PeopleSearch.im MCP server

Give your AI agent PeopleSearch.im: search a global professional database in plain English, reveal full profiles, and fetch verified professional (work) emails, plus email verification, reverse email lookup, LinkedIn lookups, and company lookups. Searching is free; most lookups cost 1 credit and are refunded automatically when nothing is found.

Listed in the Official MCP Registry as im.peoplesearch/email-finder.

Connect (remote server, recommended)

No install. The server runs at:

https://peoplesearch.im/api/mcp

The first time your assistant uses a PeopleSearch.im tool, it asks you to sign in and approve the connection (OAuth). No API key to copy.

Claude and ChatGPT: add the URL above as a custom connector (in ChatGPT, choose OAuth).

Claude Code:

claude mcp add --transport http peoplesearch https://peoplesearch.im/api/mcp

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "peoplesearch": {
      "url": "https://peoplesearch.im/api/mcp"
    }
  }
}

VS Code (.vscode/mcp.json):

{
  "servers": {
    "peoplesearch": {
      "type": "http",
      "url": "https://peoplesearch.im/api/mcp"
    }
  }
}

Prefer an API key? (Windsurf, scripts, clients without OAuth)

Create a key (sk_sift_...) on the developer page and send it as a Bearer header:

claude mcp add --transport http peoplesearch https://peoplesearch.im/api/mcp \
  --header "Authorization: Bearer sk_sift_..."

{
  "mcpServers": {
    "peoplesearch": {
      "serverUrl": "https://peoplesearch.im/api/mcp",
      "headers": { "Authorization": "Bearer sk_sift_..." }
    }
  }
}

Connect (local stdio bridge)

For clients that only speak stdio, this repository is a zero-dependency bridge (index.mjs, Node 18+). It speaks MCP over stdio and forwards each tool call to the PeopleSearch.im REST API with your API key:

{
  "mcpServers": {
    "peoplesearch": {
      "command": "npx",
      "args": ["-y", "github:yumaheymans/peoplesearch-mcp"],
      "env": { "PEOPLESEARCH_API_KEY": "sk_sift_..." }
    }
  }
}

Or clone the repository and run node index.mjs with PEOPLESEARCH_API_KEY set. PEOPLESEARCH_BASE_URL optionally overrides the API base (default https://peoplesearch.im).

Tools

Data comes from Icypeas, a B2B people-data provider. Emails are professional (work) addresses looked up live, not personal ones. A lookup can come back empty, and then the credit is refunded.
