Postproxy

Publish to multiple social networks with only one MCP

Documentation

Postproxy MCP Server

MCP (Model Context Protocol) server for integrating Postproxy API with Claude Code. This server provides tools for publishing posts, checking statuses, and managing social media profiles through Claude Code.

Installation

Global Installation

npm install -g postproxy-mcp

Local Installation

npm install postproxy-mcp

Claude Code stores MCP server configuration under ~/.claude/plugins/. After installing postproxy-mcp, Claude will automatically detect the server on restart.

Configuration

Register MCP Server

After installing postproxy-mcp, register it with Claude Code using the claude mcp add command:

claude mcp add --transport stdio postproxy-mcp --env POSTPROXY_API_KEY=your-api-key --env POSTPROXY_BASE_URL=https://api.postproxy.dev/api -- postproxy-mcp

Replace your-api-key with your actual Postproxy API key.

The configuration will be automatically saved to ~/.claude/plugins/. After running this command:

Restart your Claude Code session
Test the connection by asking Claude: "Check my Postproxy authentication status"
If tools are available, Claude will be able to use them automatically

Alternative: Interactive Setup

For non-technical users, you can use the interactive setup command:

postproxy-mcp setup

postproxy-mcp-setup

This will guide you through the setup process step by step and register the server using claude mcp add automatically.

Available Tools

Authentication Tools

`auth_status`

Check authentication status, API configuration, and workspace information.

Parameters: None

Returns:

{
  "authenticated": true,
  "base_url": "https://api.postproxy.dev/api",
  "profile_groups_count": 2
}

Account Overview

`summary_get`

Answer "what's the status?" in one call — an activity snapshot for a time window instead of separate history_list / comments_list / dm_chats_list round trips.

Parameters:

window (string, optional): 24h (default), 7d, or 30d
from (string, optional): ISO 8601 timestamp or bare date starting an explicit range. Overrides window, and the *_previous counts come back null
to (string, optional): End of the explicit range. Defaults to now when only from is given
profile_group_id (string, optional): Report on a single group. Omit to cover every group the key can reach

Returns:

{
  "window": {
    "label": "24h",
    "from": "2026-08-17T09:00:00Z",
    "to": "2026-08-18T09:00:00Z",
    "previous_from": "2026-08-16T09:00:00Z",
    "backlog_from": "2026-07-19T09:00:00Z"
  },
  "posts": {
    "published": 4,
    "published_previous": 3,
    "failed": 1,
    "scheduled_ahead": 6,
    "next_scheduled_at": "2026-08-18T14:00:00Z",
    "by_platform": { "instagram": { "published": 4, "failed": 0 } }
  },
  "engagement": {
    "total": { "impressions": 48210, "likes": 1204 },
    "by_platform": { "instagram": { "impressions": 31002, "likes": 900 } },
    "posts_with_insights": 14
  },
  "comments": { "received": 96, "received_previous": 71, "awaiting_reply": 12, "by_platform": { "instagram": 61 } },
  "reviews": { "received": 7, "received_previous": 4, "awaiting_reply": 3 },
  "dms": { "inbound": 41, "outbound": 33, "chats_awaiting_reply": 5, "reply_window_closing": 2 },
  "api": { "calls": 812, "calls_previous": 640 }
}

Notes:

Post counts are posts, so a post sent to three networks counts once and a thread counts once. by_platform counts per-network deliveries, so a 3-item X thread is 3 under twitter.
engagement is lifetime-to-date for posts published in the window, not engagement earned during it — it sums each post's newest stats snapshot. A post published minutes ago may have no snapshot yet and won't be in posts_with_insights. Keys are the normalized metrics listed in Stats Fields by Platform.
The awaiting_reply counts describe current state, not the window — they don't change when you change window. They look back 30 days, returned as window.backlog_from. A comment counts as replied only when the reply came from you (via Postproxy or the profile itself); chats_awaiting_reply is derived from message timestamps, since Postproxy has no read/unread state.
reply_window_closing counts chats with under 6 hours of their 24h messaging window left. Networks without a window (Telegram, Bluesky) are excluded.
engagement is null when insights are off for the account; dms is null when DMs are off.
Scoped like every other tool: a group-scoped key reports only its group.

Profile Management

`profile_groups_list`

List all profile groups accessible with your API key. Profile groups are organizational containers (e.g. per brand or client) that hold related profiles. Use a group's id to filter profiles_list by profile_group_id.

Parameters: None

Returns:

{
  "profile_groups": [
    {
      "id": "grp123abc",
      "name": "Main Brand",
      "profiles_count": 4
    }
  ]
}

`profiles_list`

List all available social media profiles for posting.

Parameters:

profile_group_id (string, optional): If provided, only profiles in this group are returned (use profile_groups_list to find group IDs)

Returns:

{
  "profiles": [
    {
      "id": "profile-123",
      "name": "My Twitter Account",
      "platform": "twitter",
      "profile_group_id": "group-abc"
    }
  ]
}

`profiles_placements`

List available placements for a profile. For Facebook profiles, placements are business pages. For LinkedIn profiles, placements include the personal profile and organizations. For Pinterest profiles, placements are boards. For Telegram profiles, placements are channels the bot can post to. For Google Business profiles, placements are locations, returned as full resource paths (accounts/X/locations/Y) to pass as location_id. For WhatsApp profiles, placements are the phone numbers on the Business Account — the placement id is the phone_number_id every whatsapp_* tool and dm_chat_create take. Available for facebook, linkedin, pinterest, telegram, google_business, and whatsapp profiles.

Parameters:

profile_id (string, required): Profile hashid

Returns (LinkedIn example):

{
  "placements": [
    {
      "id": null,
      "name": "Personal Profile"
    },
    {
      "id": "108520199",
      "name": "Acme Marketing"
    }
  ]
}

Notes:

If no placement is specified when creating a post:
- LinkedIn: defaults to the personal profile
- Facebook: defaults to a random connected page (if only one page is connected, no need to set a placement ID)
- Pinterest: it fails
- Telegram: it fails — chat_id is required on every post
- Google Business: it fails — location_id is required on every post and on every google_business_* tool

`profiles_stats`

Get the follower/engagement timeseries for a profile. Snapshots are captured roughly every 23 hours, so you can plot follower growth and other trends over time. The stats fields are platform-native (not normalized) — see Stats Fields by Platform in the post_stats section for shape and add-on profile-level keys (followers_count, followersCount, etc.) per network.

Parameters:

profile_id (string, required): Profile hashid
placement_id (string, conditional): Required for facebook, linkedin, telegram, and google_business profiles. Get it from profiles_placements. Omit for instagram, threads, youtube, twitter, tiktok, pinterest, and bluesky.
from (string, optional): ISO 8601 timestamp — only include snapshots recorded at or after this time
to (string, optional): ISO 8601 timestamp — only include snapshots recorded at or before this time

Returns (LinkedIn example):

{
  "data": {
    "profile_id": "prof_li_001",
    "platform": "linkedin",
    "placement_id": "108520199",
    "records": [
      { "stats": { "followerCount": 4500, "shareCount": 8, "likeCount": 80 }, "recorded_at": "2026-05-09T08:00:00Z" },
      { "stats": { "followerCount": 4520, "shareCount": 9, "likeCount": 90 }, "recorded_at": "2026-05-10T08:00:00Z" }
    ]
  }
}

For non-placement networks (e.g. Bluesky), omit placement_id:

{
  "data": {
    "profile_id": "prof_bsky_001",
    "platform": "bluesky",
    "placement_id": null,
    "records": [
      { "stats": { "followersCount": 8800, "postsCount": 40 }, "recorded_at": "2026-05-09T08:00:00Z" }
    ]
  }
}

Parameters:

queue_id (string, required): Queue ID

Returns:

{
  "next_slot": "2026-03-11T14:00:00Z"
}

Adding Posts to a Queue

When publishing a post with post_publish, you can add it to a queue instead of scheduling it manually:

queue_id (string, optional): Queue ID to add the post to. The queue will automatically assign a timeslot. Do not use together with schedule.
queue_priority (string, optional): Priority level: high, medium (default), or low. Higher priority posts get earlier timeslots.

Example:

  "content": "Queued post content",
  "profiles": ["twitter", "linkedin"],
  "queue_id": "q1abc",
  "queue_priority": "high"
}

Comment Management

`comments_list`

List comments on a published post. Returns paginated top-level comments with nested replies.

Parameters:

post_id (string, required): Post ID
profile_id (string, required): Profile ID to identify which platform's comments to retrieve
page (number, optional): Page number, zero-indexed (default: 0)
per_page (number, optional): Number of top-level comments per page (default: 20)
from (string, optional): ISO 8601 date/time — only comments received at or after this point
to (string, optional): ISO 8601 date/time — only comments received at or before this point

from/to filter on when Postproxy received the comment, not the platform's posted_at (which isn't always populated). A bare date such as 2026-03-25 means that date's start of day. The filter applies to top-level comments only — a comment in range still returns its full replies array.

Returns:

{
  "total": 42,
  "page": 0,
  "per_page": 20,
  "data": [
    {
      "id": "cmt_abc123",
      "external_id": "17858893269123456",
      "body": "Great post!",
      "status": "synced",
      "author_username": "someuser",
      "like_count": 3,
      "is_hidden": false,
      "posted_at": "2026-03-25T10:00:00.000Z",
      "replies": [
        {
          "id": "cmt_def456",
          "body": "Thanks!",
          "author_username": "author",
          "parent_external_id": "17858893269123456"
        }
      ]
    }
  ]
}

Comment objects may also include an attachments array (media on the comment — image, video, audio, gif, external, file), each with id, type, url, status, and external_id. Populated for Facebook, Threads, and Bluesky; Instagram, YouTube, and LinkedIn comments are text-only. The array is empty when there is no media.

Direct Messages

1:1 messaging (chats and messages) on DM-capable profiles. Supported on Facebook (Messenger), Instagram (DMs), Telegram (Bot DMs), Bluesky, and WhatsApp. Outbound sends are processed asynchronously (returned with status: "pending"). Meta's 24h messaging window applies to Facebook/Instagram — a human replying to the participant's own inquiry can pass tag: "HUMAN_AGENT" to send outside it (up to 7 days, never for promotional or automated content); Telegram and Bluesky have no window. On WhatsApp the window is re-opened only by sending an approved template (template) or a category: "utility" text — see WhatsApp Business Management for the rest of the WhatsApp surface.

`dm_chats_list`

List chats for a profile, ordered by most recent activity.

Parameters:

profile_id (string, required): Profile ID (Facebook, Instagram, Telegram, Bluesky, or WhatsApp)
page (number, optional): Page number, zero-indexed (default: 0)
per_page (number, optional): Items per page (default: 20)
before / after (string, optional): ISO 8601 timestamp filters on last_message_at

WhatsApp chats also carry external_placement_id (the phone number the chat belongs to), group (true for group chats) and within_messaging_window.

`dm_chat_create`

Find or create a chat for a participant (idempotent — returns the existing chat if one exists). Use before messaging a participant the profile hasn't messaged yet.

Parameters:

profile_id (string, required): Profile ID
participant_external_id (string, required): Platform participant ID (IG-scoped user ID, Facebook PSID, Telegram user id, Bluesky DID, or a WhatsApp phone number with country code — non-digits are stripped)
placement_id (string, optional): Placement id from profiles_placements. Required on WhatsApp (the phone number the chat is on); optional on Facebook (page id)
participant_username (string, optional)
participant_name (string, optional)

A brand-new WhatsApp conversation has no open messaging window, so the first send into it must be a template (see dm_message_send).

`dm_chat_get`

Get a single chat by Postproxy ID or platform external_conversation_id.

Parameters:

chat_id (string, required): Chat ID or external conversation ID

`dm_messages_list`

List messages in a chat, most recent first.

Parameters:

chat_id (string, required): Chat ID or external conversation ID
page (number, optional): Page number, zero-indexed (default: 0)
per_page (number, optional): Items per page (default: 20)
direction (string, optional): inbound or outbound
status (string, optional): Filter by message status

`dm_message_send`

Send an outbound message. Provide exactly one of body (text), media (a single attachment), or — on WhatsApp — template, interactive, location or contacts.

Parameters:

chat_id (string, required): Chat ID or external conversation ID
body (string, optional): Message text (required when nothing else is sent; on WhatsApp it may also accompany media as the caption)
media (string[], optional): Up to one attachment as a URL or local file path. Not supported on Bluesky. (The remote/Worker MCP accepts URLs only.) WhatsApp limits: image 5MB jpeg/png, video 16MB mp4/3gpp, audio 16MB, document 100MB.
tag (string, optional): HUMAN_AGENT to send outside the 24h window — extends it to 7 days from the participant's last inbound message (Facebook/Instagram only). Meta restricts it to a human replying to the participant's own inquiry; using it for marketing, offers, or automated re-engagement can get that Page / Instagram account's messaging capability suspended. Past 7 days Meta rejects the send and the message lands in status: failed with the platform error in error_details.
reply_to_external_id (string, optional): Telegram & WhatsApp — platform message id (Telegram message_id, WhatsApp wamid) to quote / thread under
reply_markup (object, optional): Telegram only — inline/reply keyboard payload
quick_replies (object[], optional): Facebook & Instagram only — up to 13 tappable chips above the participant's composer. Each { title, payload }.

Quick replies and buttons

Facebook Messenger and Instagram Direct only — on Telegram use reply_markup instead (passing these returns a 422). Quick replies are ephemeral chips that vanish once one is tapped; buttons stay attached to the message in the thread.

	`quick_replies`	`buttons`
Max per send	13	3
`title`	required, ≤20 chars	required, ≤20 chars
`payload`	required, ≤1000 chars	required for `postback`, ≤1000 chars

{
  "chat_id": "chat_xyz789",
  "body": "What can I help with?",
  "quick_replies": [
    { "title": "Track order", "payload": "TRACK" },
    { "title": "Talk to support", "payload": "HELP" }
  ]
}

{
  "chat_id": "chat_xyz789",
  "body": "Nike Air Max",
  "card": { "subtitle": "$129 · Arriving Friday", "image_url": "https://cdn.example.com/shoe.png" },
  "buttons": [
    { "type": "web_url", "title": "Buy now", "url": "https://shop.example.com/p/air-max" },
    { "type": "postback", "title": "Notify me", "payload": "NOTIFY:air-max" }
  ]
}

Buttons are delivered as a Meta generic template whose element title is your body — that's where the 80-character cap comes from. Instagram is stricter than Messenger: it delivers quick replies only on a plain-text message, so quick_replies with media or with buttons returns 422 there.

Receiving taps: a tapped chip or button postback arrives as an inbound message carrying tapped_action: { "kind": "quick_reply" | "postback" | "callback_query", "payload": "...", "title": "..." }. Read it from dm_messages_list / dm_message_get instead of digging through platform_data. Instagram ice-breaker taps and Telegram callback queries normalize to the same field.

WhatsApp templates and interactive messages

A WhatsApp number can only send free-form text, media, interactive, location and contacts while the participant's 24h window is open (within_messaging_window on the chat). Outside it — including a conversation you start yourself — send an approved template. variables fill the placeholders in order (header text vars first, then body vars, then dynamic URL button vars) and must match the template's variable_count from whatsapp_templates_list; the rendered body is stored on the message.

{
  "chat_id": "chat_wa1",
  "template": {
    "name": "order_update",
    "language": "en_US",
    "variables": ["Ana", "ORD-12345"]
  }
}

Templates with a media header take header_media: { "link": "https://..." }; a location header takes header_location; URL / copy-code / flow buttons take button_params: [{ "index": 0, "sub_type": "url", "parameters": [{ "type": "text", "text": "12345" }] }].

Inside the window, interactive is Meta's own object — reply buttons (up to 3), a list (up to 10 rows), a CTA URL, a product card, a flow or a location request:

{
  "chat_id": "chat_wa1",
  "interactive": {
    "type": "button",
    "body": { "text": "Ready to confirm your booking?" },
    "action": {
      "buttons": [
        { "type": "reply", "reply": { "id": "confirm", "title": "Confirm" } },
        { "type": "reply", "reply": { "id": "reschedule", "title": "Reschedule" } }
      ]
    }
  }
}

A tap comes back as an inbound message whose body is the tapped title, with the reply id under platform_data.interactive. Facebook/Instagram quick_replies / buttons return 422 on WhatsApp, and template / interactive / location / contacts / category return 422 on every other network.

`dm_message_get`

Get a single message by Postproxy ID or platform external_id.

Parameters:

message_id (string, required): Message ID or external ID

`dm_message_edit`

Parameters:

message_id (string, required): Message ID or external ID
body (string, optional): New text/caption
reply_markup (object, optional): New keyboard (or {} to remove)

`dm_message_react` / `dm_message_unreact`

Add or remove your business account's reaction on a message. Facebook Messenger, Instagram Direct and WhatsApp.

Parameters (dm_message_react):

message_id (string, required): Message ID or external ID

Parameters (dm_message_unreact):

message_id (string, required)

`dm_chat_archive` / `dm_chat_unarchive`

Archive (mute) or unarchive (unmute) a chat. Bluesky only. Returns the chat with archived set.

Parameters:

chat_id (string, required): Chat ID or external conversation ID

`dm_chat_mark_read`

Mark a chat as read. On WhatsApp this sends the read receipt (blue ticks) for the newest inbound message; on other networks it only stamps metadata.read_at. Returns the chat.

Parameters:

chat_id (string, required): Chat ID or external conversation ID

`dm_comment_private_reply`

Send a DM to the author of a comment, in reply to that comment (Meta "Private Replies"). Bypasses the 24h window (comments up to 7 days old) and creates/reuses a chat automatically. One private reply per comment, ever. Instagram and Facebook only.

Parameters:

post_id (string, required): Post ID
comment_id (string, required): Comment ID or external ID
profile_id (string, required): Profile ID (Instagram or Facebook)
text (string, required): DM text
quick_replies (array, optional): Up to 13 chips — same shape as dm_message_send
buttons (array, optional): Up to 3 buttons — same shape as dm_message_send; caps text at 80 characters
card (object, optional): Card styling for buttons (subtitle, image_url, default_action)

Interactive elements follow the same rules as dm_message_send — on Instagram, quick_replies and buttons are mutually exclusive. Media attachments are not available on private replies.

History

`history_list`

List recent post jobs.

Parameters:

limit (number, optional): Maximum number of jobs to return (default: 10)

Returns:

{
  "jobs": [
    {
      "post_id": "job-123",
      "content": "Full post body as submitted...",
      "content_preview": "Post content preview...",
      "created_at": "2024-01-01T12:00:00Z",
      "overall_status": "complete",
      "status": "processed",
      "scheduled_at": "2024-01-02T09:00:00Z",
      "draft": false,
      "source": "postproxy",
      "queue_id": null,
      "platforms_count": 2,
      "platforms": [
        {
          "platform": "twitter",
          "status": "published",
          "url": "https://x.com/user/status/123"
        }
      ]
    }
  ]
}

scheduled_at is null for posts that were published immediately. status is the raw API status (draft, scheduled, processing, processed, …), while overall_status folds platform outcomes into a single verdict.

Note: Postproxy's /posts API does not return profile identity (profile ID or name) per platform — only the network. Use profiles_list to map networks to connected profiles.

Google Business Profile Management

These edit the Google business listing itself — hours, attributes, services, food menus, action links and profile photos — as opposed to publishing local posts to it (that's post_publish with platform google_business).

Three rules apply to every tool in this group:

location_id is always required. It's the full Google resource path accounts/X/locations/Y, returned by profiles_placements.
Updates are field-masked. Each write takes a fields array naming exactly what's being replaced. Anything named in fields but absent from the payload is cleared, and nested objects are replaced wholesale rather than merged. Always read before you patch.
Availability varies by category and region. Attributes, service lists, food menus and action link types differ per listing. List what's available first; a location that isn't eligible returns 422.

Payloads use Google's own shapes and camelCased keys in both directions, so a response can be sent straight back as a request body.

Tool	Purpose
`google_business_location_get`	Read the listing — name, description, website, phones, categories, address, hours, service area, metadata
`google_business_location_update`	Update listing fields (`title`, `websiteUri`, `phoneNumbers`, `categories`, `storefrontAddress`, `serviceArea`, `labels`, `latlng`, `openInfo`, `profile`, `storeCode`)
`google_business_categories_list`	Resolve category resource names (`categories/gcid:*`) for a region — needed for any `categories` patch
`google_business_hours_update`	Set `regularHours`, `specialHours` and `moreHours`
`google_business_attributes_get`	Read attributes currently set
`google_business_attributes_available`	List which attributes this listing can set, with value types
`google_business_attributes_update`	Set attributes
`google_business_service_list_get`	Read the service list
`google_business_service_list_update`	Replace the service list (needs `metadata.canModifyServiceList`)
`google_business_food_menus_get`	Read food menus (restaurant-like categories only)
`google_business_food_menus_update`	Replace food menus (needs `metadata.canHaveFoodMenus`)
`google_business_place_action_links_list`	List action buttons ("Book online", "Order online")
`google_business_place_action_link_create`	Add an action button
`google_business_place_action_link_update`	Update an action button
`google_business_place_action_link_delete`	Remove an action button
`google_business_media_list`	List profile photos and videos
`google_business_media_create`	Add a photo or video
`google_business_media_delete`	Remove a photo or video

Typical flow

1. profiles_placements                    → get location_id
2. google_business_location_get           → read current state
3. google_business_attributes_available   → see what this listing accepts
4. google_business_attributes_update      → patch only what changed

Attribute value shapes

google_business_attributes_available returns a valueType per attribute, which decides the shape to send back:

valueType	Shape
`BOOL`	`{ "name": "attributes/offers_online_appointments", "values": [true] }`
`URL`	`{ "name": "attributes/url_linkedin", "uriValues": [{ "uri": "https://..." }] }`
`ENUM`	`{ "name": "attributes/preferred_messaging_service", "repeatedEnumValue": { "setValues": ["TOKEN"] } }`

attribute_mask defaults to exactly the names you send, so a partial update never clears attributes you left out.

Hours

Times accept either "09:00" / "09:00:00" strings or Google's { "hours": 9, "minutes": 0 } objects — both are normalized before the call. Read current hours from google_business_location_get; each block named in fields is replaced entirely.

{
  "fields": ["regularHours"],
  "regularHours": {
    "periods": [
      { "openDay": "MONDAY", "openTime": "09:00", "closeDay": "MONDAY", "closeTime": "18:00" }
    ]
  }
}

Media

Google downloads the file from media_url itself — there is no upload step, so the URL must be publicly reachable https (not a short-lived signed URL, not localhost). Images need at least 250×250 and at most 5MB. category defaults to ADDITIONAL; use COVER or LOGO only when you intend to change the profile header or logo.

Reading empty results

Google omits keys rather than returning empty values: a listing with no attributes returns { "name": "..." } with no attributes key at all, and the same applies to serviceItems, placeActionLinks and boolean flags like isPreferred. Treat absent as empty.

Analytics

Google Business location analytics come through the standard profiles_stats tool — pass the location_id as placement_id. Metrics are Search and Maps impressions (desktop and mobile), website clicks, call clicks, direction requests, conversations, bookings, food orders and food-menu clicks. Google Business has no follower count, and Google exposes no per-post analytics for local posts.

WhatsApp Business Management

Manage a connected WhatsApp Business Account beyond the inbox: message templates, phone-number status and registration, the public business profile, display name and username, blocked users, groups, and Click-to-WhatsApp conversion reporting. Conversations themselves go through the dm_* tools above.

Four rules apply to every tool in this group:

The WhatsApp Business Account (WABA) is the profile; each phone number on it is a placement. Phone-scoped tools take phone_number_id — the placement id from profiles_placements (its metadata carries display_phone_number, quality_rating, messaging_limit_tier, name_status, platform_type).
Templates and the Conversions dataset are WABA-level — those tools take only profile_id.
Free-form messages only inside the 24h window. Once a participant's last inbound message is older than 24h (or the conversation is new), dm_message_send accepts only an APPROVED template (or a category: "utility" text). A delivered template re-opens the window.
Coexistence numbers are limited. A number connected with onboarding: "business_app" (still in the WhatsApp Business app on a phone) has lower throughput and cannot use the Groups API; whatsapp_number_info reports platform_type other than CLOUD_API for these.

Responses use Meta's own field names where Meta's shapes are returned (components, interactive, business profile fields).

Tool	Purpose
`whatsapp_templates_list`	List synced templates (filter `name`, `language`, `status`; `refresh: true` re-syncs from Meta first)
`whatsapp_template_get`	One template with components, status and `variable_count`
`whatsapp_template_create`	Submit a custom template (`components`) or instantiate a library one (`library_template_name`)
`whatsapp_template_update`	Change `components` (back to PENDING review) and/or `message_send_ttl_seconds`
`whatsapp_template_delete`	Delete one language (`language`) or the whole name
`whatsapp_template_library_get`	Inspect a Meta library template before instantiating it
`whatsapp_number_info`	Live number + WABA status: quality rating, messaging tier, name status, platform type
`whatsapp_number_register`	Register the number with the Cloud API using its 6-digit PIN
`whatsapp_number_request_verification_code`	SMS / voice verification code for an unverified number
`whatsapp_number_verify`	Submit the verification code
`whatsapp_business_profile_get`	Public profile: about, address, description, email, websites, vertical, photo
`whatsapp_business_profile_update`	Update those fields (`about` ≤139, `description` ≤512, ≤2 websites)
`whatsapp_business_profile_photo_update`	Replace the profile photo (`url` or base64 `data`; JPEG/PNG ≤5MB)
`whatsapp_display_name_get`	Verified display name and review status
`whatsapp_display_name_request_change`	Submit a new display name for Meta review
`whatsapp_username_get` / `_set` / `_delete` / `_suggestions`	Manage the number's `wa.me` username
`whatsapp_blocked_users_list` / `whatsapp_blocked_user_status`	Who is blocked
`whatsapp_users_block` / `whatsapp_users_unblock`	Block / unblock up to 1000 numbers per call
`whatsapp_groups_list` / `_create` / `_get` / `_update` / `_delete`	Groups the number administers (Cloud API numbers only)
`whatsapp_group_participants_add` / `_remove`	Manage members (a group holds 8)
`whatsapp_group_invite_link_create`	Fresh invite link (revokes the previous one)
`whatsapp_group_join_requests_list` / `_approve` / `_reject`	Handle join requests on approval-required groups
`whatsapp_dataset_get` / `whatsapp_dataset_create`	Conversions API dataset on the WABA
`whatsapp_conversion_event_send`	Report a LeadSubmitted / Purchase / AddToCart / InitiateCheckout / ViewContent for a Click-to-WhatsApp conversation

Typical flow

1. profile_groups_initialize_connection   → platform: whatsapp (onboarding: api | business_app)
2. profiles_placements                    → get phone_number_id
3. whatsapp_templates_list                → find an APPROVED template and its variable_count
4. dm_chat_create                         → participant_external_id: phone, placement_id: phone_number_id
5. dm_message_send                        → template: { name, language, variables }
6. dm_messages_list                       → the reply opens a 24h window; free-form sends now work

Connecting a number

profile_groups_initialize_connection with platform: "whatsapp" returns a connect URL. Pass onboarding: "business_app" when the number lives in the WhatsApp Business app on a phone (the user scans a QR code; the app keeps working alongside Postproxy and up to 6 months of chats are imported) or onboarding: "api" when the number is with another provider or brand new (moved onto the Cloud API; no longer usable in the app). Omit it and the connect page asks. Each WhatsApp Business Account becomes one profile and each of its numbers a placement.

Templates

Meta reviews every custom template; a new one is PENDING until approved, and only APPROVED templates can be sent. Placeholders are {{1}}, {{2}}… (parameter_format: POSITIONAL, the default) or {{name}} (NAMED). variable_count on a template is the number of variables a send must carry: header text placeholders, then body placeholders, then one per dynamic-URL button. Library templates (whatsapp_template_library_get → whatsapp_template_create with library_template_name) skip review. A name is unique per language; deleting by name without language removes every language.

Conversions

Conversations that start from a Click-to-WhatsApp ad carry a ctwa_clid on the chat's metadata. Create a dataset once (whatsapp_dataset_create), then report outcomes with whatsapp_conversion_event_send by chat_id or phone; a chat with no captured ctwa_clid returns 422.

Platform Parameters Reference

Instagram:

format: "post" | "reel" | "story"
collaborators: Array of usernames (max 10 for posts, 3 for reels)
first_comment: String - comment to add after posting
cover_url: String - thumbnail URL for reels
audio_name: String - audio track name for reels
trial_strategy: "MANUAL" | "SS_PERFORMANCE" - trial strategy for reels
thumb_offset: String - thumbnail offset in milliseconds for reels
user_tags: Array of { username, x, y, media_index } - tag public Instagram accounts on any format (post, reel, story). Images require x and y (floats 0.0–1.0 from the top-left corner); reels and video slides are tagged by username only (coordinates are dropped); stories accept coordinates but don't need them. media_index picks the carousel slide (0-based, default 0). A leading @ is stripped. Out-of-range coordinates, a media_index past the last media item, or an image tag missing x/y are rejected with a 422 naming the entry. Private accounts and accounts with tagging off are silently skipped by Instagram.

Troubleshooting

Server Won't Start

Check API Key: Ensure POSTPROXY_API_KEY is set when registering with claude mcp add
Check Node Version: Requires Node.js >= 18.0.0
Check Installation: Verify postproxy-mcp is installed and in PATH
Check Registration: Ensure the server is registered via claude mcp add and configuration is saved in ~/.claude/plugins/

Authentication Errors

AUTH_MISSING: API key is not configured. Make sure you included --env POSTPROXY_API_KEY=... when running claude mcp add
AUTH_INVALID: API key is invalid. Verify your API key is correct.

Validation Errors

TARGET_NOT_FOUND: One or more profile IDs don't exist. Use profiles_list to see available profiles.
VALIDATION_ERROR: Post content or parameters are invalid. The API now returns detailed error messages:
- 400 errors: {"status":400,"error":"Bad Request","message":"..."}
- 422 errors: {"errors": ["Error 1", "Error 2"]} - Array of validation error messages
- Check the error message for specific validation issues

API Errors

API_ERROR: Postproxy API returned an error. Check the error message for details.
Timeout: Request took longer than 30 seconds. Check your network connection and API status.

Platform Errors

When checking post status with post_status, platform-specific errors are now available in the error field of each platform object:

error: null - Post published successfully
error: "Error message" - Detailed error message from the platform API
Common errors include authentication issues, rate limits, content violations, etc.

Draft Post Issues

If you create a draft post (draft: true) but receive draft: false in the response:

The response will include a warning field explaining that the API may have ignored the draft parameter
This can happen if:
- The API does not support drafts with media attachments
- The API has specific limitations for draft posts under certain conditions
Check the warning field in the response for details
Enable debug mode (POSTPROXY_MCP_DEBUG=1) to see detailed logging about draft parameter handling

Debug Mode

Enable debug logging by setting POSTPROXY_MCP_DEBUG=1 when registering the server:

claude mcp add --transport stdio postproxy-mcp --env POSTPROXY_API_KEY=your-api-key --env POSTPROXY_BASE_URL=https://api.postproxy.dev/api --env POSTPROXY_MCP_DEBUG=1 -- postproxy-mcp
