}Frequently asked questions
No. The public MCP server is unauthenticated. Use it from ChatGPT connectors (developer mode), Claude custom connectors, or Claude Code.
MCP is the native protocol. The OpenAPI snippet on each card is for a custom GPT Action if you are still on that path.
Tester is a generic client for any server. This gallery is our server — copy, install, call.
