Composio

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.
