Composio and Runner
Runner gives your AI agent an OAuth-protected MCP connection, checks the caller's permission on every call, holds each answer to the shape its tool declares, and gives admins a stop control from the whole workspace down to a single tool.
What it is usually bought for
Give an AI agent useful work across your stack
The job, on its own page: Give an AI agent useful work across your stackBuilt into Runner
- An MCP endpoint your agent connects to, with OAuth
- Permissions checked fresh on every call, never from a cached copy
- Every tool is graded, with consequential work routed to a person
- Each answer checked against the shape its tool declares before it goes back
- A stop control for the workspace, a project, one tool or one person's connections
Worth knowing
What an agent may call follows the permissions of the teammate it signed in as, checked again on every call, and anything irreversible or destructive stays off the list by design. A tool that changes a record is served only once it declares the go-ahead it needs, the evidence it carries and how it is undone, and that go-ahead is given by a person elsewhere, never over the connection — these are the controls around an agent, not an agent deciding for you.
When to keep Composio
- If Composio does this job well for you today, keep it. Nothing on this page asks you to move.
- Runner stops where the bound above says it stops, and a tool you already run may cover exactly that.
Use what already works
Connect an MCP client that signs in with OAuth and names its product on each request. It signs in as one of your teammates, and every call is checked against that person's permissions at the moment it runs, so a change of role applies to the next call.
