The open standard connecting AI models to tools and data — USB-C for agents.
You're looking at a software record: a tool or platform in the AI stack — who maintains it and what hardware it runs on.
MCP, introduced by Anthropic in November 2024, defines how models discover and call external tools, files and services. OpenAI, Google, Microsoft and the major IDEs adopted it within a year, and it moved to open governance — the closest thing the agent ecosystem has to a universal port.
