MCP servers

Agents get their tools from MCP servers — what they are, the two kinds, and how you attach one to an agent.

Agents get their abilities from MCP servers. An MCP server exposes a set of tools — read a log range, list Kubernetes pods, fetch a pull request diff — and an agent calls those tools while it works. Everything an agent can see or do outside ilert comes from an MCP server you connected.

There are two kinds:

Kind	Who runs it	What you provide
ilert hosted	ilert, inside its own infrastructure	A credential for your system (and, for some servers, a small component deployed in your network)
External	You, or the vendor of the tool	The server's public HTTPS URL plus the credential it expects

Both kinds are connected the same way: you create a connector once, then attach it to an agent on the agent's Tools tab and choose which of its tools the agent may use.
