A command-line interface for interacting with MCP (Model Context Protocol) servers that lets Claude access external tools, APIs, and data sources. You'll use this when you need Claude to read files, query databases, hit APIs, or interact with services like GitHub through their MCP servers. It provides discovery commands to list available servers and tools, inspection commands to see JSON schemas, and execution commands to actually call the tools with arguments. The workflow is straightforward: discover what's available, explore tool parameters, then execute with JSON payloads. Includes search functionality and different output formats for scripting.
