Fusion MCPilot
Portable agent skill for Autodesk Fusion 360 over MCP with reusable workflows for parametric modeling, geometry validation, and 3D-print prep.
What it does and how it connects
Fusion MCPilot is a portable AI agent skill for Autodesk Fusion 360 over MCP. It supplies the skill, recipes, validation, and optional client helpers for native parametric modeling, live CAD state inspection, parameter changes, geometry validation, and metric 3D-print preparation.
It connects an agent to Fusion's existing local MCP service: the repository does not install a replacement Fusion MCP server. Setup is to install Fusion, enable its local MCP service, install the fusion-360-mcp skill folder in the agent's skill directory, and register the Fusion endpoint (a common local address is http://127.0.0.1:27182/mcp).
The README states it is an independent community project, not affiliated with or endorsed by Autodesk, OpenAI, or Prusa Research. Installation is documented for ChatGPT Work, Codex, Claude Code, Cursor, and other agents, with a Windows adapter and a portable Python installer.

Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- Cloud-first file model makes local file control, rename/move/backup workflows feel alien and risky.Error Index
- General UI/UX is described as confusing and hostile for routine work.Error Index
- One failed fusion360 MCP call ate 23% of a Claude usage window, per the Haitch morning digest's smaller-items list.Error Index
- an agent-built parametric plywood panel passes 149 offline tests with green CI, but Fusion measurements and screenshots were NOT RUN, so live correctness is UNKNOWN before anything touches Fusion or a CNC.Error Index
