Findymail MCP Server

An MCP (Model Context Protocol) server that wraps the Findymail API, giving AI assistants access to email finding, verification, and enrichment tools.

Setup

1. Install dependencies and build

npm install
npm run build

2. Get your API key

Retrieve your API token from the Findymail API page.

3. Configure in your MCP client

The server supports two transport modes:

Stdio mode (local, e.g., Claude Desktop)

Add to your MCP client configuration (e.g., Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "findymail": {
      "command": "node",
      "args": ["/path/to/findymail-mcp/dist/index.js"],
      "env": {
        "FINDYMAIL_API_KEY": "your-api-key-here"
      }
    }
  }
}

HTTP mode (remote connections)

Set the PORT environment variable to start the server with Streamable HTTP transport:

FINDYMAIL_API_KEY=your-api-key PORT=3000 node dist/index.js

The MCP endpoint will be available at http://localhost:3000/mcp. Configure your MCP client to connect to this URL.
