Model Context Protocol (MCP)

Also known as MCP

The Model Context Protocol (MCP) is an open standard for connecting LLM applications to external tools, data sources, and other agents through a common interface, rather than every integration being a bespoke one-off. It's the plumbing that lets a single tool or data connector be written once and reused across different agents and applications. Adopting it early is part of building model-agnostic, vendor-neutral agent systems instead of tools wired to one specific assistant — though MCP standardizes the wire format for that connection, not the catalog, contract, or permission decisions behind it.
