MCP protocol

MCP (Model Context Protocol) is the open standard, introduced by Anthropic in November 2024, that enables Large Language Models (LLMs) to securely access and interact with external systems and real-time data.

The Model Context Protocol (MCP) is an open-source standard designed to solve the 'N×M' data integration problem for AI agents: it replaces custom connectors with a single, universal interface. Developed by Anthropic and released in November 2024, MCP standardizes secure, two-way communication between an LLM application (the MCP client) and external data sources or tools (the MCP server). This architecture allows models to move beyond static training data, enabling real-time actions like querying a Postgres database or sending a Slack message via a structured JSON-RPC 2.0 transport layer. Major industry players, including OpenAI and Google DeepMind, have already adopted the protocol, with official SDKs available in languages like Python and TypeScript to accelerate ecosystem development.
