Google Knowledge Graph MCP Server

Model Context Protocol server that connects Claude (or any MCP client) to Google's free public Knowledge Graph API. Search for real-world entities - people, places, organisations, concepts - and get structured data back. It runs locally over stdio via the published package.

People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

Claude Code

claude mcp add houtini-ai-google-knowledge-graph-mcp -- npx -y @houtini/google-knowledge-graph-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "houtini-ai-google-knowledge-graph-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@houtini/google-knowledge-graph-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

npm package @houtini/google-knowledge-graph-mcp - the @houtini scope differs from the repo owner (houtini-ai); confirm it's the project's official package

registry namespace io.github.houtini-ai is GitHub-verified and matches the repo owner

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
