Composio
MCP & connectorsA platform that gives agents authenticated access to hundreds of apps through managed tools.
Composio provides a large catalogue of ready-made tools — across SaaS apps and developer services — that an agent can call, with authentication and token handling managed for you.
The hard part of agent tooling is rarely the call; it is OAuth, refresh tokens, and per-user permissions. Composio absorbs that, exposing capabilities over MCP and SDKs.
Where it's ideally used
A strong fit when an agent needs to act across many third-party apps and you want auth and connector upkeep handled for you.
Where it doesn't fit
Unnecessary weight when an agent only ever touches one or two internal systems you already hold credentials for.
