I connected the MCP Server to Cursor using HTTPS. Cursor successfully connects and shows that 6 tools are available. However, when I make a request I am not getting back a response. I reconnected using the NPM package and it does work successfully, but only 3 tools are available. How do I get the HTTPS Server working in Cursor?

MCP Server Not Sending Properly Formatted Responses
Hello, same issue here:
MCP error -32600: Tool search has an output schema but did not return structured content
- Client: Cursor IDE (latest version)
- OS: macOS (darwin 25.2.0)
- MCP Server: Lucid Software (official integration via Cursor's MCP settings)
- Enable the Lucid Software MCP server in Cursor IDE (Settings → Features → MCP)
- Complete OAuth authentication successfully
- Attempt to use any Lucid MCP tool (e.g., search with query "document" or fetch with a valid document ID)
- Observe the error
- search with various queries ("document", "a", "") - all fail
- fetch with a valid document UUID - also fails
