The inspector is a diagnostic and validation tool for the Model Context Protocol. It provides an interactive interface and a transport proxy to discover, inspect, and execute the tools, prompts, and resources provided by an MCP server.
The project serves as a debugger and compliance tester to verify that server implementations adhere to the protocol specification and JSON-RPC standards. It allows for real-time monitoring of message exchanges and logs between clients and servers across various transport layers, such as standard input/output and Server-Sent Events.
The tool covers a broad range of testing capabilities, including tool execution validation using JSON schemas, resource inspection, and the testing of prompt templates. It also facilitates connectivity debugging to ensure stable communication during the initial handshake and capability negotiation phase.
