AI-ready Try oda mcp servers

Open IFC Viewer includes a built-in MCP server. Connect your AI agent to the open model and let it explore the building, read property sets, analyze geometry and add walls, doors or furniture.

Need the same for your own IFC, STEP or DWG files, or inside your own product? That is what ODA MCP Servers are for.
