Signado MCP
Warm lead discovery for Claude Code, Codex, ChatGPT, and Grok Bot.
This repository is the public listing page for Signado's hosted MCP endpoint. It does not contain product source code. Connect your existing workspace, then ask your assistant to list warm leads, inspect LinkedIn engagement context, find emails, and save AI outreach drafts back to Campaigns.
Endpoint
https://mcp.signado.io/mcp
Connect Claude Code
claude mcp add --transport http signado https://mcp.signado.io/mcp
Then run /mcp, choose signado, and authenticate in your browser.
Claude Code reads Signado's OAuth client details automatically.
Connect Codex
codex mcp add signado --url https://mcp.signado.io/mcp
codex mcp login signado
Approve the browser prompt with your existing Signado account and choose the workspace to connect. Codex reads Signado's OAuth client details automatically.
Connect Claude web
In Settings → Connectors, add a custom connector named Signado for
https://mcp.signado.io/mcp. Keep authentication on Always required. Under
OAuth client, keep Use Anthropic's hosted client metadata (Recommended).
Under Advanced, keep Streamable HTTP, add the connector, then approve the
Signado sign-in.
Connect ChatGPT
In Settings → Plugins, enable developer mode if needed, then select + → New
Plugin. Name it Signado, enter https://mcp.signado.io/mcp, and choose
OAuth. Under Advanced OAuth settings, keep Client Identifier Metadata
Document (CIMD) as the registration method. Create the plugin, then sign in
with Signado and approve access.
Connect Grok Bot
Send this message to your bot:
Add a custom MCP server called signado at https://mcp.signado.io/mcp
Grok Bot adds the connector and shows a connect card. Select Authorize, sign in with Signado, choose the workspace to connect, and approve access. No API key or auth header is needed.
Tools and credit costs
The connector advertises 15 tools. qualify and catchup_source are hidden from the listing but remain callable as compatibility aliases, for 17 callable tools in total.
Read and export
| Tool | What it does | Cost |
|---|---|---|
ping | Checks the connection and selected workspace. | 0 credits |
list_warm_leads | Lists warm leads with ICP scores, companies, LinkedIn engagement context, and a best_of_run boolean. | 0 credits |
get_best_of_run | Returns stored Best of run selections from completed Discovery runs. Mechanical runs rank by composite score, always keep the top lead, then keep scores of at least 60 up to five. The exact quote and run boundary remain; verdict, why, and angle are nullable legacy fields from historical model-selected runs. | 0 credits |
get_warm_lead_detail | Loads one warm lead's complete LinkedIn engagement history on demand. | 0 credits |
export_leads | Exports warm leads as structured CSV rows for a date window. | 0 credits |
list_templates | Lists system templates, workspace templates, and authoring rules. | 0 credits |
Discovery sources
| Tool | What it does | Cost |
|---|---|---|
preview_source | Optionally previews a keyword, creator, Company page, or post source. Completed empty previews retain their fixed charge; a Company page with no recent original posts is a valid empty result. | 1 credit |
add_source | Adds keyword, creator, or Company page monitoring with an optional Daily or Custom schedule, or saves a LinkedIn post PAUSED for Once-only discovery. Post scope is Commenters, Reactors, or Both (default Both); post creation never accepts or seeds a recurring schedule. | 0 credits to add, then normal discovery credits when run |
set_source_schedule | Changes an existing keyword, creator, or Company page source to Daily or to selected ISO weekdays at one local time in an IANA timezone. Edits affect only future runs. | 0 credits |
run_source_once | Runs an active/paused keyword, creator, or Company page, or a paused post, once. Post Both requires at least two lead slots. Zero-engagement runs settle unused lead credits. | 0 credits to queue, then credits for leads actually found |
cancel_source_run | Cancels an in-flight one-time run. Leads already found stay; unspent credits come back automatically. | 0 credits |
catchup_source | Legacy alias of run_source_once, kept for back-compat. | Same as run_source_once |
remove_source | Archives a source while keeping the history in place. | 0 credits |
add_source keyword mode:
keyword_modeis optional and only valid whensource_type = "keyword".- Omit it, or pass
"post_engagers", to find people commenting on matching LinkedIn posts. - Pass
"post_authors"to find the people who wrote matching LinkedIn posts, including zero-comment posts when the author is person-shaped. source_type = "competitor_creator"does not acceptkeyword_mode; creator sources still monitor engagers on that creator's posts.source_type = "company"requiresprofile_urlto be a LinkedIn/company/...URL and does not acceptkeyword_mode. It remains a Company Page source in returned source and Warm Leads metadata.- Company-account comments are filtered; people commenting from personal profiles, including company employees, remain eligible warm leads.
Custom schedules use ISO weekday numbers (1 = Monday through 7 = Sunday),
one local_time for every selected weekday, and an IANA timezone such as
Europe/London. Both add_source and set_source_schedule show a no-write
plan first and require confirm: true to change monitoring. Schedule edits
recompute the next future run and never trigger a retroactive run. Post sources
remain Once-only and reject Daily or Custom schedules. The saved UTC due instant
remains canonical if an MCP runtime cannot render a PostgreSQL-supported zone
alias locally; the tool returns a localization warning instead of failing after
the schedule was saved.
Creator and Company page sources use the same profile-source credit infrastructure: 1 credit for Preview or a Daily profile-post scan, 5 credits per new warm lead, and the plan-configured re-engagement rate. They reuse the existing creator ledger actions and refund rules without changing their public source type. A valid scan with no recent posts keeps the scan charge; a hard full-chain failure is reported and refunded rather than silently pausing.
add_source post mode:
- Set
source_type = "post"and providepost_url. post_engagement_scopeis"commenters","reactors", or"both"(default).- Post sources are saved paused and are Once-only. Optionally call
preview_source, then callrun_source_oncewith a confirmed credit ceiling. - The reactor capability belongs only to post sources; keyword and creator sources cannot inherit it.
Examples:
{ "source_type": "keyword", "keyword": "website redesign", "keyword_mode": "post_engagers", "confirm": false }
{ "source_type": "keyword", "keyword": "website redesign", "keyword_mode": "post_authors", "confirm": false }
{ "source_type": "post", "post_url": "https://www.linkedin.com/feed/update/urn:li:activity:1234567890", "post_engagement_scope": "both", "confirm": false }
{ "source_type": "company", "profile_url": "https://www.linkedin.com/company/mondaydotcom/", "confirm": false }
{ "source_name": "Competitor scans", "schedule": { "mode": "custom", "weekdays": [1, 2, 3, 4, 5], "local_time": "08:00", "timezone": "Europe/London" }, "confirm": false }
Enrichment and outreach
| Tool | What it does | Cost |
|---|---|---|
find_email | Finds emails for selected leads and writes results back to Warm Leads. | 5 credits per contact |
