execute_python3

MCP tool from Rhino MCP by tanishqbhattad

CPython 3 via RhinoCode (Rhino 8.11+, Developer mode)

How to use it

Project documentation lists execute_python3 for the Rhino MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
