A minimalistic MCP client for testing MCP Server

MCP Client for Testing

A minimalistic MCP (Model Context Protocol) client for testing tool calls in MCP servers.

Usage

Install uv and test a tool call in an MCP server like this:

uvx mcp-client-for-testing \
    --config '
    [
        {
            "name": "name of mcp server",
            "command": "uv",
            "args": [
                "--directory", 
                "path/to/root/dir/", 
                "run", 
                "server.py"
            ],
            "env": {}
        }
    ]
    ' \
    --tool_call '{"name": "tool-name", "arguments": {}}'

To use it as in your code, install the package with:

uv pip install mcp-client-for-testing 

and use it like this:

import asyncio
import json
from mcp_client_for_testing.client import execute_tool

async def main():
    config = [
        {
            "name": "name of mcp server",
            "command": "uv",
            "args": [
                "--directory", 
                "path/to/root/dir/", 
                "run", 
                "server.py"
            ],
            "env": {}
        }
    ]
    tool_call = {"name": "tool-name", "arguments": {}}
    
    await execute_tool(config, tool_call)

if __name__ == "__main__":
    asyncio.run(main())
