About AEC Model Bridge
AEC Model Bridge is an MCP server published by the GitHub account Sam-AEC. Revit MCP server: 200+ tools to read and edit BIM models, every change human-approved.
It runs on your own machine: your AI client starts it from the MCP bundle package aec-model-bridge-1.4.0.mcpb at version 1.4.0.
It asks for one secret: MCP_REVIT_ANTHROPIC_API_KEY. Give it a key with the least access that still works.
Version 1.4.0 was published on 9 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 8 automated checks on the registry entry and the package code: 6 pass, 0 warn, 0 fail, 2 info. How we check.
