Tool Calling
When an AI model invokes a structured external function during a conversation.
Tool calling (or function calling) is how modern AI clients execute actions: the model selects a tool, supplies JSON arguments, and receives structured results. MCP standardizes this pattern across clients like Claude, ChatGPT, Cursor, and Gemini.
MCP360 tools are validated with strict schemas and return JSON data — never executable instructions — to keep agent behavior predictable.
