Model Context Protocol (MCP)
An open protocol (Anthropic, Nov 2024) for exposing tools, data and prompts to LLM applications through a standard server interface.
MCP lets any coding agent connect to any tool server — databases, issue trackers, browsers, internal APIs — without bespoke integration per model. Adopted by OpenAI, Google, Microsoft and most agent products during 2025. Stack Overflow's 2025 survey found 34.4% of developers building agents use MCP servers.
