MCP Client

MCP Client

A CLI tool for interacting with Anthropic's Claude model using MCP (Model Context Protocol) servers.

Features

• Connect to multiple MCP servers defined in a configuration file
• Interactive chat with Claude using available MCP tools
• Stream Claude's responses in real-time
• Support for both interactive and single-query modes
• Rich terminal output with clear formatting

Installation

# Clone the repository
git clone https://github.com/lingster/mcp-llm.git
cd mcp-llm

# Install with uv
uv sync 

Configuration

Create a JSON configuration file that defines your MCP servers. For example:

{
  "mcpServers": {
    "brave-search": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-brave-search"
      ],
      "env": {
        "BRAVE_API_KEY": "your-api-key-here"
      }
    }
  }
}

Save this file to one of these locations:

• ~/.config/mcp-client/config.json
• ~/.mcp-client.json
• ./mcp-client.json
• ./config.json

Alternatively, you can specify a custom config file with the --config option.
