MCP server for interacting with Autodesk Civil 3D.
If you want an AI assistant working directly with Civil3d MCP, the civil3d mcp mcp server is the bridge. MCP server for interacting with Autodesk Civil 3D.
An MCP server that enables AI assistants to write and execute C# code directly inside Autodesk Civil 3D. Instead of fixed tools, the AI generates code that runs with full API access.
Once connected, the assistant can call these 3 tools directly:
civil3d_execute — Execute C# code with write access (transaction committed)civil3d_query — Execute C# code read-only (no commit)civil3d_skills — Browse/search/read code skill templatesSetup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.
The server reads one environment variable: CIVIL3D_HOST. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Civil3d MCP sits in that group, and the shape of its toolset — civil3d_execute, civil3d_query, civil3d_skills — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
