From Protocol to Intelligence: Powering Agents with MCP.

---

📍 Overview

MCP Agent Tool Adapter enables modular tool invocation via the MCP protocol, and provides agents that can dynamically reason with tools using either Google ADK or LangGraph.

This project transforms MCP tools into:

• 🤖 Google ADK-based agents with streaming FastAPI or CLI interfaces
• 🧠 LangGraph-based agents that use ReAct + streaming tool planning

🚀 Getting Started

☑️ Prerequisites

• Python 3.10+

⚙️ Installation

# Clone this repository
❯ git clone https://github.com/serkanyasr/mcp-agent-tool-adapter
❯ cd mcp-agent-tool-adapter

# Install dependencies
❯ pip install -r requirements.txt

---

🤖 Usage

Run Google ADK CLI agent:

❯ python app_client_adk.py

Run LangGraph ReAct CLI agent:

❯ python app_client_langgraph.py

Ensure your mcp_config.json defines tools like:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["@modular-protocol/filesystem"]
    }
  }
}

🧠 Tool Architecture

MCP tools are connected to agents through MCPClient, which handles:

• Tool server spawning (via subprocess)
• Session management
• Tool adaptation (langgraph or Google ADK)
• Cleanup

You can dynamically swap agent type by changing tool_type to "google" or "langgraph" in your app.
