A Model Context Protocol (MCP) server that provides CAD generation and verification tools for Claude Code. This server enables conversational 3D
Most developer tooling work still happens through a UI a human drives. Cadquery MCP server moves it into the conversation instead. A Model Context Protocol (MCP) server that provides CAD generation and verification tools for Claude Code. This server enables conversational 3D modeling by exposing CAD-Query functionality through MCP tools.
The server publishes 5 tools. What each one is for:
macOS — Location: ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — The Windows tool exposed by this serverConfiguration — The Configuration tool exposed by this serververify_cad_query — Validates a CAD-Query generated model against specified criteriaTesting — The Testing tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Cadquery's toolset — macOS, Windows, Configuration and 2 more — is a fair guide to whether it matches your workflow. It is maintained by rishigundakaram; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Cadquery's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
