+##### MCP for Gemini Enterprise Agent Platform
+
+To use MCP with Agent Platform, provide the MCP tool you want to use to
+`Tool.mcp_servers` in your `generate_content` request. See
+[here](https://docs.cloud.google.com/gemini-enterprise-agent-platform/reference/mcp#toolsets)
+for a list of available MCP tools.
+
+The `mcp` package is required to use Agent Platform MCP servers.
+You can install it with `pip install mcp`.
+
+```python
+import asyncio
+from google import genai
+from google.genai import types
+
+PROJECT_ID="your-gcp-project"
+LOCATION="your-location"
