MCP Peek - Inspect, run & proxy MCP

MCP Peek is a specialized desktop application designed for deep inspection and debugging of Model Context Protocol (MCP) servers. It provides a direct interface to: * Inspect every tool, resource, and prompt * Manually run server tools with custom inputs * Capture and view raw request and response traffic * Monitor live token usage for server operations This tool allows developers to bypass intermediary models and interact directly with MCP servers. Users can reproduce specific calls, examine raw data, and understand how a server genuinely responds before integration into an agent. MCP Peek offers an unfiltered view of server behavior, ensuring precise debugging and accurate development. Beyond direct interaction, MCP Peek can function as a proxy, sitting between your client and MCP servers to observe every call made live. This provides a critical debugging layer, showing exactly what your agent sends and receives. It's an indispensable utility for validating server definitions and ensuring seamless integration. Perfect for developers and engineers building and maintaining server-side components that conform to the Model Context Protocol, offering clarity and control over server interactions. Available across macOS, Windows, and Linux.
