Client Ref
Provides a terminal-based user interface for testing Model Context Protocol (MCP) servers.
About
Client Ref is a terminal-based client designed for interacting with and testing Model Context Protocol (MCP) servers. Built with the Textual TUI library, it allows developers to connect to MCP servers defined in a configuration file (following the format used by the Claude Desktop app) and inspect their functionality. It leverages the magentic library to connect to LLM APIs, and defaults to using the Claude Haiku model (requiring an ANTHROPIC_API_KEY). The client also features an inspector screen accessible through the command palette, aiding in debugging and testing server behavior.
