# Integrations

> An integration is something Executor connects to, defined by an MCP server, an OpenAPI spec, or a GraphQL endpoint.

An **integration** is something Executor can connect to. Each integration is defined by
a source that describes the available tools:

* an **MCP server**
* an **OpenAPI** specification
* a **GraphQL** endpoint

The integration describes the catalog of tools; on its own it isn't a live, authenticated
connection. To actually call tools, you create a [connection](/concepts/connections).
