tool use function calling

Builds on OpenAI function calling and tool use patterns, adding protocol-level synchronization and agent awareness of tool availability.

MCP tools are how structured capabilities are exposed to LLMs; article demonstrates tool implementation as part of MCP.

MCP depends on LLM's function calling capability; article assumes this as prerequisite

MCP is fundamentally about how agents discover and call tools; the article's claims example shows agents using MCP-exposed APIs as tools

MCP overview section and 'Building Tools' segment directly address how agents structure and invoke external tools—tool use is foundational to context management

Tools described as differentiator between chatbot (text) and agent (action); function calling protocol enables context-aware action selection

MCP servers expand Claude's tool access patterns beyond built-in functions; configuration is part of tool context architecture

MCP enables AI to call external tools—Mutiny uses this for exposing visitor context as callable context

MCP is a structured protocol for tool integration; this demonstrates how tool use surfaces external context

MCP servers represent an abstraction layer above traditional function calling, enabling systematic tool integration

The ability to 'read, click through, and interact' suggests Claude is using tools to navigate and extract content from websites, similar to browser automation via function calls.
