KingMinos MCP Server

Connect a coding agent to KingMinos at https://mcp.kingminos.com/mcp. The server is Streamable HTTP. It wraps the HTTP API at https://api.kingminos.com. One tool per live route.

It is not the OutboundSync product MCP. KingMinos pages stay on kingminos.com.

Auth is the same tenant Bearer as REST. Put the key in KINGMINOS_API_KEY. Clients send Authorization: Bearer <your-key>. A bare key is 401 malformed. Never print or commit the API key.

Sign in at app.kingminos.com to mint a km_ token. See Authentication. The machine-readable HTTP contract is GET /openapi.json.

Endpoint	https://mcp.kingminos.com/mcp
Transport	Streamable HTTP
Health	https://mcp.kingminos.com/health

Connect

Add to ~/.cursor/mcp.json (or project .cursor/mcp.json):

{
  "mcpServers": {
    "kingminos": {
      "url": "https://mcp.kingminos.com/mcp",
      "headers": {
        "Authorization": "Bearer ${env:KINGMINOS_API_KEY}"
      }
    }
  }
}

Other Streamable HTTP clients use the same pair: URL and Bearer header.

Cursor GUI sessions do not inherit shell .env files. Export KINGMINOS_API_KEY into the GUI environment so ${env:KINGMINOS_API_KEY} resolves.

Tools

One tool per live route the MCP pin advertises. Capability POSTs spend credits. Confirm put_credentials, delete_credentials, and delete_subject with the user before calling them. POST /v1/company/x-account is on the HTTP API and in the capability catalog; it is not an MCP tool yet.

Tool	Route	Notes
get_providers	GET /v1/providers
get_capabilities	GET /v1/capabilities	Catalog. A 200 proves the key.
get_recipes	GET /v1/recipes	Agent chaining recipes. Write guidance is GET /v1/recipes/guidance.
company_resolve	POST /v1/company/resolve	Name-only is no_decision. See Company resolve.
company_b2b_social	POST /v1/company/b2b-social	Paths speed / balance / accuracy / coverage. Domain required. See Company B2B social.
company_icon	POST /v1/company/icon	Hosted https://logos.kingminos.com/i/<sha256>.png or null. Favicon-fetch, then Brandfetch BYOK, then ZoomInfo. See Company icon.
company_description	POST /v1/company/description	Paths speed / balance / accuracy / coverage. AI Ark firmographics; ZoomInfo BYOK on coverage. Stamp when answer.confidence meets the path floor. See Company description.
company_domain	POST /v1/company/domain
company_hierarchy	POST /v1/company/hierarchy
person_verify_employment	POST /v1/person/verify-employment	LeadMagic default. Findymail is BYOK-only.
person_language	POST /v1/person/language	English engagement and alternatives. See Person language.
person_phone	POST /v1/person/phone	One dialable number plus the ranked rest. See Person phone.
person_title	POST /v1/person/title	Current title, seniority and function. See Person title.
person_name	POST /v1/person/name	Proper-cased first, last and full name. See Person name.
person_b2b_social	POST /v1/person/b2b-social	The person’s LinkedIn profile URL from an email. See Person B2B social.
get_run	GET /v1/runs/{id}
submit_feedback	POST /v1/feedback	Free, never costs credits. Not a support channel. File it when a call misses or comes back low-confidence, when you had to work around KingMinos, or when you wanted a field or provider we don’t have. See Feedback.
list_credentials	GET /v1/credentials	Status only — never the secret. See Vendor keys.
put_credentials	PUT /v1/credentials/{provider}	Confirm with the user. See Vendor keys.
delete_credentials	DELETE /v1/credentials/{provider}	Confirm with the user.
delete_subject	DELETE /v1/subjects/{subject_key}	Confirm with the user. Requires the erase scope.

House keys vs vendor keys

LeadMagic, Wiza, Findymail, and AI Ark are house-key vendors. ZoomInfo, Brandfetch, BuiltWith, Prospeo, Apollo, Company URL Finder, People Data Labs, HG Insights, Enrich-CRM, Lemlist, and Snov.io (credentials only) are vendor keys you store (BYOK). Websearch and favicon-fetch are house-only and cannot be stored.

MCP vs API vs Skills

Surface	Best for
MCP (this page)	A coding agent calling KingMinos tools from Cursor or another Streamable HTTP client
CLI	npx kingminos against the HTTP API
API	Scripts and the OpenAPI contract at /openapi.yaml
Agent Skills	Structured workflows (auth, company-resolve, credentials). Prefer REST. This pack does not ship the MCP server.
