How to test your MCP server against Goose
Run npx @mcpjam/inspector@latest, connect the server config you already use, and select Goose. MCPJam drives your server the way this host does, including its model (openai/gpt-5-nano), so you see the tool calls it actually makes instead of guessing from a bug report.
From there, Trace shows every step from prompt to response, the OAuth Debugger shows where authorization breaks, and Evals score whether the model picks the right tool across realistic requests. All of it runs locally, free and open source.
