Protocol examples

A GET in the address bar returns 405 because this endpoint expects MCP POST messages. Use the examples below or the official SDK client to test it.

Scope and compatibility

The server returns metadata and file URLs. It cannot purchase, inspect a private account, write to a local project or render an interactive 3D viewer inside every chat client.

Only anonymous, published catalog facts are returned. Unknown facts remain null; recorded import checks apply to the exact GLB hash and do not certify performance.

Metadata shares a best-effort edge limit of 120 requests per minute per IP at each Cloudflare location. File downloads have no account download quota.

• POST: initialize / notifications / tools/list / tools/call
• GET / DELETE: 405 · OPTIONS: 204
• JSON response · no persistent session ID · 32 KiB message limit
• tools/call: content + structuredContent; isError=true on invalid arguments
