MCP

Search local CAD archives from Claude, Codex, and other MCP clients.

CADCrawl MCP uses your CADCrawl API key to index and retrieve STEP, STP, STL, and 3MF files from local folders.

Get an API key

Create a CADCrawl account, start an eligible monthly or annual subscription, then issue an MCP API key from the API keys tab. Copy it when it is created; it is only shown once.

Install Bun

Bun is required because the MCP server uses local SQLite storage.

powershell -c "irm bun.sh/install.ps1 | iex"

Add to Codex

Replace ccad_... with the API key from your CADCrawl dashboard.

codex mcp add cadcrawl --env CADCRAWL_API_KEY="ccad_..." -- bunx @cadcrawl.com/mcp

Claude

Replace ccad_... with the API key from your CADCrawl dashboard.

claude mcp add --env CADCRAWL_API_KEY="ccad_..." cadcrawl -- bunx @cadcrawl.com/mcp

Install the Codex skill

The skill tells Codex how to use CADCrawl retrieval without wasting repeated searches.

npx skills add cadcrawl/mcp --skill cadcrawl-mcp

Troubleshooting

Unable to connect: confirm `https://api.cadcrawl.com/health` opens from the same machine.

401: the API key is missing, copied incorrectly, or revoked.

403: MCP API keys require an active monthly or annual subscription.

429: the account reached the daily MCP API request limit.

No results: index the target folder first with the CADCrawl MCP indexing tool.
