MCP Server with Google ADK Project

This project implements a Model Context Protocol (MCP) server using Google's Agent Development Kit (ADK) for building intelligent agents and tools. The system features multiple specialized agents that collaborate through a coordinator agent to handle different types of requests.

Prerequisites

• Python 3.9+
• Groq and OpenRouter Key

Setup

1. Clone this repository
2. Create a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   

3. Install dependencies:

   pip install -r requirements.txt
   

4. Set up your Groq & Openrouter Key: add key in .env if available otherwise create file as

touch .env 

add key

OPENROUTER_API_KEY="ADD_Your_Key"
GROQ_API_KEY="ADD_Your_Key" 

Running the MCP Server

python server.py

This will start the MCP server on http://0.0.0.0:8080

Available Agents

Coordinator Agent

The coordinator agent uses LLM-based routing to direct requests to the most appropriate specialized agent. It analyzes the content of the request and determines which agent can best handle it.

Search Agent

Performs web searches and provides information on various topics.

Example Request:

curl -X POST http://localhost:8080/ask -H "Content-Type: application/json" -d '{"query":"What is Model Context Protocol?"}'

Data Analysis Agent

Analyzes data from various file formats (CSV, Excel) and generates reports with visualizations.

Example Request:

curl -X POST http://localhost:8080/ask -H "Content-Type: application/json" -d '{"file_path": "sales_data.xlsx","query":"make a report for these data"}'

Code Generator Agent

Generates code in various programming languages based on natural language descriptions.

Example Request:

curl -X POST http://localhost:8080/ask -H "Content-Type: application/json" -d '{"query":"Python code for fibonacci series","language":"python"}'

API Endpoints

• /ask - General endpoint that routes to the appropriate specialized agent
• /search - Endpoint for direct web searches
• /analyze-data - Endpoint for data analysis
• /generate-code - Endpoint for code generation
• /chat/completions - Chat completion endpoint for conversational interaction

MCP Tools

The server exposes the following MCP tools:

• ask - Routes the user's query to the most appropriate agent
• search - Searches the web for information
• analyze_data - Analyzes data files and generates reports with visualizations
• generate_code - Generates code based on natural language descriptions

Extending This Project

To add new agents:

1. Create a new file in the agents/ directory
2. Implement the agent class with an async process() method
3. Update the coordinator agent to recognize and route to the new agent

To add new tools:

1. Create a new file in the tools/ directory
2. Implement the tool functionality with comprehensive docstrings
3. Import and use the tool in your agents
