25.0717 Lab notes (Gdrive), Git

• 1 Agent has built-in tool functions
  • Direct Python functions (file operations, calculations, API calls)
  • No external protocol needed
  • Example: weather_api(city), file_read(path), math_calculate(expression)
• 2 Agent decides when to use tools
  • Based on prompt keywords or patterns
  • Simple if/else logic or regex matching
  • Example: if "weather" in question → call weather_api()
• 3 Agent executes tools directly
  • Calls local functions or libraries
  • Makes direct HTTP requests to APIs
  • Processes files on local filesystem
• 4 Agent formats tool results for model
  • Converts API responses to readable text
  • Example: {"temp": 25, "desc": "sunny"} → "Temperature is 25°C, sunny"

Note: Traditional tools are simpler but less standardized than MCP. MCP provides discovery, validation, and standardized interfaces.
