Graphlens MCP

A free, MIT-licensed MCP server that gives coding agents (Claude Code, Cursor, and compatible clients) a semantic code graph of your project - symbols, cross-file calls, references, imports and cross-language boundaries. 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 Jupyter Notebook.

01 · Install Graphlens MCP

Claude Code

claude mcp add neko1313-graphlens-mcp -- uvx graphlens-mcp

      "command": "uvx",
      "args": [
        "graphlens-mcp"
      ]
    }
  }
}

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