Glossary
Also: MCP
An open standard through which language models reach tools and data sources: one shared interface instead of one integration per vendor.
Before MCP every tool needed its own connection to every model. The standard inverts that: a server offers tools and resources, any client can use them.
For companies the consequence matters more than the standard itself: the connection to internal systems becomes a reusable component instead of being rebuilt inside every tool.

Four things: permission checks per call on behalf of the requesting user, rate limiting, traceable logging of every tool call, and a cap against loops. The tools themselves are the easy part.
