Revit MCP Server

AI chat for Autodesk Revit that lives inside Revit. No Claude Desktop. No external apps. Just a native chat panel, a WebSocket server, and 53+ tools that talk directly to the Revit API.

Author: Sanjay Chauhan | GitHub

A native WPF chat panel docked inside Revit. The plugin and MCP server communicate over WebSocket on localhost — the AI sees your active view, selection, and model context in real time. No middleman.

Supports multiple AI providers out of the box: OpenRouter (100+ models), Anthropic Claude, DeepSeek, and Qwen. Switch providers by changing one line in your .env file. Run Qwen locally through Ollama for free.

53 specialized tools cover query, selection, visibility, views, sheets, MEP, tagging, and export. 5 additional dynamic intent tools (query, execute, analyze, navigate, create) work across any Revit category — so "query Walls", "query Conduit", "query Electrical Fixtures" all work without needing a separate hardcoded tool for each.
