+## 🔌 MCP Server Integration
+
+This app is a **real MCP server**! When running, it exposes its functionality as tools that other AI agents can call via the Model Context Protocol.
+
+**MCP Endpoint:** `http://localhost:7860/gradio_api/mcp/`
+
+This means:
+- Other AI agents can use Explainor as a tool
+- Enables agent-to-agent communication
+- Part of the growing MCP ecosystem
+
