How this service works
Debug MCP server connection and tool-call failures - stdio transport, initialize handshake, tool schemas, isError results, inspector
Output
A JSON object containing a guide record with fields: id (unique identifier), t (title of the guide), c (category), body (full markdown or plain-text article covering MCP stdio transport setup, initialize handshake debugging, tool schema validation, isError result interpretation, and MCP inspector usage), price (nullable number), and license (license identifier string).
Example use cases
Fixing MCP stdio transport startup
“My MCP server using stdio transport won't connect — the initialize handshake seems to be failing. Can you get me the guide on debugging MCP connection and tool-call failures so I can figure out what's wrong?”
Diagnosing isError tool-call results
“My MCP tool calls keep returning isError results and I don't know how to interpret them. Can you fetch the Saylor Innovations article on MCP tool-call failures to help me understand what's going wrong?”
Using MCP inspector for troubleshooting
“I want to learn how to use the MCP inspector to trace what's happening with my server — can you pull up the guide that covers MCP inspector usage and tool schema debugging?”
