When to choose this
Choose MCP Inspector when you need a comprehensive testing tool for MCP servers, especially for developers who want to interactively test tools, debug connections, and explore server capabilities before integration.
When NOT to choose this
Avoid if you need a production-ready MCP server implementation itself rather than a testing tool, or if you prefer minimal dependencies - the Inspector requires a Node.js environment and browser interface.
