MCP CLI Client

What is MCP CLI Client?

MCP CLI Client is a command-line tool and Python library for connecting to MCP (Machine Communication Protocol) servers via local STDIO connections and remote SSE (Server‑Sent Events) connections. It is built for developers who need to interact with MCP servers from the terminal or integrate MCP functionality into their own Python projects.

How to use MCP CLI Client?

Clone the repository, create and activate a Python virtual environment, install dependencies with pip install -r requirements.txt, and copy .env.example to .env to configure settings. Use python main.py with --local or --remote flags to send JSON‑RPC requests, or launch the interactive mode with python main.py --local. For module usage, install with pip install -e . and import MCPClient for programmatic control.
