What is the Model Context Protocol?
Glossary · AI agent and machine identity security
Short answer
The Model Context Protocol (MCP) is an open standard that lets AI applications connect to tools and data sources through a common interface.
Why it matters
A shared interface makes it easy to connect agents to many systems. It also makes it easy to connect them to systems nobody reviewed.
What it looks like
A coding assistant connects to a repository server, a database server and a browser server, each with its own credentials.

nerl0 maps the MCP servers that agents use and what the credentials behind them can reach. See MCP servers.
