The Fragmentation of Agentic Tooling
Until recently, connecting a Large Language Model to external context meant writing custom functions for every individual tool: one schema for OpenAI function calling, another for LangChain tools, and yet another for custom REST endpoints.
The Model Context Protocol (MCP) introduces a universal, bi-directional JSON-RPC protocol enabling AI assistants to securely discover and consume tools and resources across host environments.
