Hey, thanks for the report. This is a known issue after updating Cursor to 2.3.41. The MCP server connects successfully (I can see “20 tools enabled” in your screenshot), but the agent can’t discover the tools. The team is working on a fix similar thread: Agent chat "No MCP resources available" when trying to use MCP
Can you share the Request ID from the chat where you see the error? (three dots in the top-right of the chat > Copy Request ID). That’ll help the team figure out the cause.
