Human Lineage

npx add-mcp 'https://humanlineage.org/api/mcp'

Connect Claude, ChatGPT or any MCP-compatible AI agent to the Human Lineage genealogical graph — search people, read profiles, list relatives and render family-tree images.

Endpoint

Human Lineage exposes a public MCP server over Streamable HTTP — no API key required:

https://humanlineage.org/api/mcp

Connect Claude Desktop

Settings → Connectors → Add custom connector → paste the endpoint URL above → Add.

Connect Claude Code

Add to .mcp.json in your project (or run claude mcp add):

{
  "mcpServers": {
    "human-lineage": {
      "type": "http",
      "url": "https://humanlineage.org/api/mcp"
    }
  }
}

Connect Cursor

Add to .cursor/mcp.json (or Settings → MCP → Add new MCP server):

{
  "mcpServers": {
    "human-lineage": {
      "url": "https://humanlineage.org/api/mcp"
    }
  }
}

Connect ChatGPT

Settings → Connectors → Advanced → enable developer mode, then Add connector → paste the endpoint URL above. (Requires a ChatGPT plan with connector support.)

Other clients

Any MCP client that supports remote Streamable HTTP servers works the same way — paste the endpoint URL where the client asks for an MCP server. Clients that only support local (stdio) servers need a bridge such as mcp-remote.
