Composio is the integration gateway that gives Ultron access to 250+ external services. You connect a service once — Composio handles auth, token refresh, API versioning, rate limit backoff, and schema normalization.
What Composio handles
| Concern | What Composio does |
|---|
| OAuth flows | Full OAuth 2.0 with PKCE, token storage, refresh |
| API versioning | Normalizes schema differences across API versions |
| Rate limit backoff | Automatic retry with exponential backoff on 429s |
| Schema normalization | Consistent tool interface regardless of underlying API |
| Error handling | Structured errors returned to Ultron, not raw API errors |

How it works in Ultron
The Composio MCP server loads in every Ultron sandbox session. When you ask Ultron to interact with any connected service, the tool call routes through Composio:
You: "Update the Acme Corp deal stage in Salesforce to Proposal."
↓
Ultron calls: composio_salesforce_update_opportunity({ id: "...", stage: "Proposal" })
↓
Composio: validates auth, calls Salesforce API, returns result
↓
Ultron: "Done — Acme Corp deal stage updated to Proposal."
Connecting a Composio integration in settings doesn’t consume credits. Credits are consumed only when a tool call executes against the service.
