What is the MCP Inspector used for?

The MCP Inspector is an interactive GUI tool that allows you to browse and test the tools, resources, and prompts provided by an MCP server to verify their functionality before deployment.

Can I test both HTTP and stdio servers?

Yes, this skill provides specific command-line workflows for both streamable HTTP transports and standard input/output (stdio) server configurations.

Does it support automated CI/CD testing?

Yes, it provides a structured approach to creating integration tests using pytest and httpx, which can be integrated into your automated development pipelines.

How does this skill help with error handling?

It includes a dedicated Phase for testing edge cases like missing fields, invalid data types, and empty inputs to ensure your server returns helpful error messages instead of crashing.

セキュリティとテスト

Validates and tests Model Context Protocol (MCP) servers using automated scripts, manual curl commands, and the MCP Inspector GUI.

This skill provides a comprehensive framework for debugging and verifying MCP servers to ensure they function correctly across different transport methods. It guides developers through starting servers in development mode, interactive testing with the official MCP Inspector, manual JSON-RPC verification via curl, and the creation of robust integration test suites with pytest. By covering edge cases and performance metrics, it helps maintain high-quality MCP implementations for seamless integration with AI clients like Claude Desktop and Cursor.
