How to Set Up and Use MCP Agent

MCP Agent is a modular Python framework that implements the Model Context Protocol with a client-server architecture over StdIO, combining LLM integration, real-time web search via the Serper API, and an advanced Graph-RAG retrieval system. It is designed as a reference implementation and building block for developers who want to create their own MCP-compatible agents with structured retrieval, tool use, and a FastAPI-backed interface for querying the agent programmatically.

Prerequisites

  • Python 3.9+ installed
  • A Serper API key for web search functionality (sign up at serper.dev to obtain SERPER_API_KEY)
  • Git to clone the repository
  • pip to install dependencies from requirements.txt
  • An MCP-compatible client such as Claude Desktop, or direct use of the FastAPI interface
1

Clone the MCP Agent repository

Clone the project from GitHub to get the full framework source code.

git clone https://github.com/AtharvaJadhav/mcp-agent.git
cd mcp-agent
2

Install Python dependencies

Install all required packages from the requirements file into your Python environment.

pip install -r requirements.txt
3

Configure environment variables

Create a .env file in the project root with your Serper API key and any optional configuration settings.

# .env
SERPER_API_KEY=your-serper-api-key-here
REQUEST_TIMEOUT=30
MAX_RESULTS=20
LOG_LEVEL=INFO
4

Start the FastAPI client interface

Launch the FastAPI server to expose the MCP agent through a REST API for programmatic access.

python -m client.fastapi_client
5

Query the agent

Send requests to the search endpoint or check the health endpoint to confirm everything is running.

# Health check
curl http://localhost:8000/health

# Search query
curl -X POST http://localhost:8000/search \
  -H 'Content-Type: application/json' \
  -d '{"query": "latest developments in AI agents", "max_results": 10}'

MCP Agent Examples

Client configuration

  }
}

Prompts to try

Example prompts and API requests to interact with the MCP Agent's search and retrieval capabilities.

- "Search the web for recent research papers on graph-based RAG retrieval systems."
- "Find the top 10 results about Model Context Protocol implementations in Python."
- "What are the latest news items about LLM agent frameworks this week?"
- "Search for tutorials on building MCP servers with Python and summarize the best one."
- "Find documentation for the Serper API and explain its rate limits."

Troubleshooting MCP Agent

Search returns empty results or 401 Unauthorized

Verify SERPER_API_KEY is correctly set in your .env file. Check your Serper account dashboard for remaining API credits. The free tier has a monthly search limit — upgrade your plan if exhausted.

FastAPI server fails to start with ImportError

Ensure all dependencies are installed: run 'pip install -r requirements.txt' again. If using a virtual environment, confirm it is activated. Python 3.9+ is required — run 'python --version' to confirm.

REQUEST_TIMEOUT errors when querying the agent

Increase the REQUEST_TIMEOUT value in your .env file (e.g., REQUEST_TIMEOUT=60). Complex queries involving multiple search result pages or RAG retrieval may take longer than the default 30 seconds.
