How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Obrotomierz Open Data to help me. It is a free service with an MCP server at https://obrotomierz.pl/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site.
