+# MCP_AGENT_EXAMPLE.py — robust full script with automatic runtime agent health check + fallback
 """
-MCP-Enabled Agent Example
-Demonstrates how to use Model Context Protocol tools with the AI Agent Boilerplate.
+Usage:
+    python MCP_AGENT_EXAMPLE.py
+    python MCP_AGENT_EXAMPLE.py --no-mongo
+This file will try to use the project's BaseAgent; if it misbehaves at runtime
+(it has incompatible method signatures / returns weird objects), the script
+automatically falls back to a MinimalAgentFallback so the demo runs cleanly.
