FreeCAD MCP Bridge

A community MCP bridge connects an agent to an open FreeCAD session through an add-on running inside the application.

Platforms: Unknown

Claude Code · Documented

The maintainer provides a Claude Code setup.

Codex · MCP compatible

Uses MCP; agent-specific setup instructions are not included in the linked documentation.

Cursor · MCP compatible

Uses MCP; agent-specific setup instructions are not included in the linked documentation.

Requirements and limitations

FreeCAD with MCP Bridge installed and enabled; an MCP client supporting the documented Streamable HTTP endpoint.

Enable the bridge in each FreeCAD session. It exposes Python execution rather than a fixed list of CAD tools; consult the repository for platform requirements.

FreeCAD MCP · addon bridge

A FreeCAD addon bridges the running application to an external MCP server.

Platforms: See documentation

Claude Code · MCP compatible

MCP transport compatibility is inferred; this agent is not explicitly documented for this connection.

Codex · MCP compatible

MCP transport compatibility is inferred; this agent is not explicitly documented for this connection.

Cursor · MCP compatible

MCP transport compatibility is inferred; this agent is not explicitly documented for this connection.

Requirements and limitations

FreeCAD with the companion addon and the documented uv-based server setup.

The addon must be active in FreeCAD; Python and workbench operations depend on the installed environment.

Questions before setup

Does one integration cover every workflow?

No such claim is made. Check the capability list, requirements and limitations of each route, then test a copy of a representative project.
