Tài liệu

Postey connects ChatGPT, Claude and other AI apps to your social accounts. Ask for a post in chat. Your AI writes one for each network, shows you the drafts, and posts when you say yes.

Free to start: publish up to 15 posts per network every 30 days.

“Turn this blog post into posts for LinkedIn and X.”

“How did my last five posts do?”

Your AI asks before anything goes live.

Publishing, scheduling, deleting and replying are marked as actions that change things, so your AI shows you the draft and waits for your yes. Postey also tells it to check your account list and confirm which account to post to.

It’s Postey’s MCP server, the standard way AI apps connect to other tools.

ChatGPT

In ChatGPT, open Plugins → + → Add custom MCP server.
Name it Postey, paste the link, leave sign-in set to OAuth, tick the risk notice and select Create. Then sign in to Postey in your browser. Step-by-step ChatGPT guide

Claude

In Claude, open Customize → Connectors → + → Add custom connector.
Paste the link and sign in to Postey in your browser. Step-by-step Claude guide

Other apps: Hermes, OpenClaw, Muse, Grokbot, and the terminal

Hermes

Register Postey with the config commands. Hermes refuses a direct edit of its config file.
Sign in, then restart the gateway from another terminal.
No browser on that machine? Mint an MCP key in Postey, set mcp_servers.postey.auth to none, send the key as headers.X-API-Key and skip hermes mcp login.

hermes config set mcp_servers.postey.url https://mcp.postey.ai/mcp
hermes config set mcp_servers.postey.auth oauth
hermes config set mcp_servers.postey.skip_preflight true
hermes mcp login postey
hermes gateway restart

OpenClaw Preview

Mint an MCP key in Postey under Settings → AI & Agents → Advanced.
Add Postey to ~/.openclaw/openclaw.json as a remote server, then restart OpenClaw.

Developer reference Authentication, MCP keys and the full tool list. You don’t need any of this to connect.

How authentication works

An unauthenticated call is refused with a challenge that points at the discovery document. A client that supports it registers itself, opens your browser, and you grant access. No API key to copy.

$ curl -sD - -X POST https://mcp.postey.ai/mcp \
    -H 'content-type: application/json' \
    -d '{"jsonrpc":"2.0","id":1,"method":"initialize"}'

HTTP/2 401
www-authenticate: Bearer resource_metadata=
  "https://mcp.postey.ai/.well-known/
   oauth-protected-resource/mcp"

GET /.well-known/oauth-authorization-server

{
  "issuer": "https://srvr.postey.ai/",
  "authorization_endpoint": ".../authorize",
  "token_endpoint": ".../token",
  "registration_endpoint": ".../register",
  "grant_types_supported": [
    "authorization_code",
    "refresh_token"
  ],
  "code_challenge_methods_supported": ["S256"],
  "client_id_metadata_document_supported": true
}

Prefer a key

A client that can’t open a browser, such as a cron job or a server, sends an MCP key instead. Mint one in Postey under Settings → AI & Agents → Advanced and send it as the header below or as a bearer token. Every grant is listed there and can be revoked one at a time.

{
  "mcpServers": {
    "postey": {
      "type": "http",
      "url": "https://mcp.postey.ai/mcp",
      "headers": { "X-API-Key": "mk_..." }
    }
  }
}

Drafts

8 create_post · update_post · get_posts · get_post_content · delete_draft · restore_post · restore_posts · resolve_share_link

tools/posts.py

create_post Create a draft. The tool tells the agent to read your account list and confirm which account to use first.
update_post Overwrite an existing draft or scheduled post. Updating a published post does not re-publish it.
get_posts List post summaries for an account, filtered by platform and status. Summaries only, no post text.
get_post_content Read the full per-platform content of one post.
delete_draft Send a draft to the trash, or delete it permanently. Drafts only.
restore_post Bring a post back out of the trash with its content intact.
restore_posts Restore several trashed posts at once. The result lists restored posts and explains any failures.
resolve_share_link Resolve a Postey share URL to post metadata. The only way in when a share link is all the agent has.

Publish & schedule

5 publish_draft · schedule_post · get_schedule · update_schedule · unschedule_post

tools/publishing.py · tools/scheduling.py

publish_draft Publish a draft to the selected platforms now. Flagged as a write action, so your app asks before it publishes.
schedule_post Schedule a draft. Each platform carries its own timestamp, so a set can be staggered. Paid plan
get_schedule Read a scheduled post back: platforms, UTC times, post actions and Auto-DM rules.
update_schedule Change the time or the platform set on a scheduled post. Paid plan
unschedule_post Cancel the schedule on one or more platforms, reverting to draft once the last one is removed.

Pre-flight checks

2 validate_post_content · convert_post_content

tools/validation.py · tools/conversion.py

validate_post_content Dry-run content against a platform's hard limit, counting rules, threading requirements and media constraints. Returns warnings and mutates nothing.
convert_post_content Adapt one post’s content from one platform to others, in place on the same post. Mechanical, not a model call.

Media

4 upload_media · file_manager · list_files · read_file

tools/media.py · uploads.py

upload_media Upload an image, video, GIF or PDF and get CDN URLs back for use in a post’s media list.
file_manager Open a drop zone in the chat. A file dropped there goes to the CDN and comes back as a URL.
list_files List the files uploaded through that drop zone. They are kept for 24 hours.
read_file Get one uploaded file’s URL, name, size and type by its id. Never the bytes.

Comments and replies

5 get_internal_comments · review_post · get_review_status · get_platform_comments · reply_comment

tools/comments.py · tools/manual_comment.py

get_internal_comments Read the team notes attached to a post inside Postey. These are never published to the network.
review_post Analyse a post and leave internal improvement notes on it. Model-backed, and it stays inside Postey. Paid plan
get_review_status Collect the result of a review_post run by its job id. Reading the status is free and never starts a second pass.
get_platform_comments List real comments left by other people on the published post. LinkedIn, X, YouTube, Instagram, Bluesky and Facebook. Paid plan
reply_comment Reply to one of those comments, published directly on the network.

Accounts & teams

6 get_accounts · connect_account · get_teams · get_team_info · add_tag · remove_tag

tools/accounts.py · tools/teams.py · tools/connect.py · tools/auth_link.py · tools/tags.py

get_accounts Every social account the caller can reach, with its connected platforms. Superseded by the accounts resource where the client can read resources.
connect_account Start a connection or a re-authorisation. Returns a link for you to open. The agent never receives a credential.
get_teams List the teams the caller belongs to.
get_team_info Full team detail, including the member list, so an agent can turn a UUID on a post into a person.
add_tag Attach a tag to an existing post. Idempotent.
remove_tag Detach a tag from a post. The tag itself survives. Idempotent.

Resources

20 Read-only state an agent can fetch without spending a tool call.

Read-only state an agent can fetch without spending a tool call. A client that can read MCP resources should read these instead of calling the equivalent tool.

Prompts

Server-supplied prompts. Your client lists them as slash commands, so the wording that gets sent is ours and stays consistent between clients.
