Debugging MCP configurations can be a time-consuming and frustrating process due to issues like trailing commas, incorrect paths, and missing environment variables. To address these challenges, a new open-source CLI tool called mcp-doctor has been developed. This tool helps users by scanning their configurations and pinpointing errors such as the exact location of trailing commas, verifying path existence, warning about missing environment variables, and testing server responsiveness. It is compatible with various platforms including Claude Desktop, Cursor, VS Code, Claude Code, and Windsurf, and can be easily installed via npm. This matters because it streamlines the debugging process, saving time and reducing frustration for developers working with MCP configurations.
