About:
MCP Inspector is an interactive debugging tool designed for testing and evaluating Model Context Protocol servers. It provides a graphical interface to inspect server capabilities, test tool calls, and debug resources in real-time. This tool streamlines the development workflow for MCP server developers and integrators.
Key Features:
  • Interactive GUI for testing MCP servers
  • Real-time debugging and inspection
  • Support for tool calls and resource evaluation
  • Visual interface for protocol exploration
Use Cases:
  • Debugging MCP server implementations during development
  • Testing tool and resource availability before integration
  • Learning and understanding MCP protocol capabilities
Alternatives:
  • curl/postman – Generic HTTP clients lack MCP-specific protocol understanding and visualization
  • custom scripts – Ad-hoc scripts require more setup and lack interactive debugging features
