Server URL: https://mcp.2022.cat
Sign-in: No sign-in. Paste the URL and it connects.
Our hands-on result: Works 7 of 7 tasks passed, tested Oct 18, 2026 with MCP TypeScript SDK (reference client).

ChatGPT setup

https://mcp.2022.cat
  1. Open Plugins on chatgpt.com, click the plus button, then Add custom MCP server. On some plans you first turn on Developer mode under Settings.
  2. Name it cat-2022-catalunya-2022 and enter the URL: https://mcp.2022.cat
  3. Set authentication to none.
  4. Tick the risk acknowledgement, create it, then start a new chat and pick it with @.

We ran the hands-on test in a reference client, not in ChatGPT. This config follows ChatGPT's documented format for remote (Streamable HTTP) servers. If it fails for you, tell us and we will retest.
