+This repository demonstrates LLM Agents using tools from Model Context Protocol (MCP) servers with several frameworks:
 - Google Agent Development Kit (ADK)
 - LangGraph Agents
 - OpenAI Agents
 - Pydantic-AI Agents
 
-Included MCP Server is based on [MCP Python SDK Quickstart](https://github.com/modelcontextprotocol/python-sdk/blob/b4c7db6a50a5c88bae1db5c1f7fba44d16eebc6e/README.md?plain=1#L104)
+Both single and multiple MCP server examples are demonstrated

+- [Agent with multiple MCP servers](agents_mcp_usage/multi_mcp/README.md)
+  - Also includes Agent evaluations
