mcp-explorer

Overview

MCP Explorer is a web-based GUI that allows users to connect to MCP servers, browse their capabilities, and interact with them directly from their browser. The tool supports both Streamable HTTP and SSE transports, with options for Bearer token or custom header authentication. Users can browse available tools, view their schemas, execute them with custom parameters, read resources, and test prompts. The interface includes a parameter store for saving frequently used values and URL history for connecting to previously used servers.
