Open Connector
Connect AI agents to hundreds of services through one integration, without putting credentials in agent code.
Open Connector is an agent-first connector platform. Integrate once to connect AI agents to hundreds of services through a growing catalog of connectors and tools. It exposes the same platform through API, SDK, and MCP, while keeping third-party credentials under your control.
Start with the hosted console; self-host when you need to run the platform in your own environment. Both paths use the same project, connection, and tool-call model.
How it works
- Your agent authenticates with a project API key.
- Open Connector resolves a connected account and injects its credential server-side.
- The provider API receives the request; the agent receives the result, not the credential.

Use Open Connector Cloud
Create a project in the console, connect a service, and make a tool call. No local infrastructure.
Self-host Open Connector
Run the same connector platform on infrastructure you control, with your own database and encryption key.
What it provides
| Feature | Detail |
|---|---|
| Encrypted vault | AES-256-GCM at rest; self-hosted instances control CONNECTOR_ENCRYPTION_KEY |
| Composio SDK compatible | Drop-in replacement — same SDK, one baseURL change |
| Multi-auth types | OAuth2 (PKCE + refresh), API_KEY, and BASIC auth all supported |
| Tamper-evident audit trail | SHA-256 hash chain — any tampered record breaks the chain |
| Self-hostable | Your Postgres, your OAuth apps, your keys — no vendor lock-in |
| Open source | Fork it, audit it, contribute to it — see LICENSING.md |
| Agent-native auth | x-api-key header with scoped metadata per Project |
Connector catalog
The catalog contains connector definitions and their available auth methods. A connector becomes usable only when its auth method is available on the target instance and you create an auth config for it. Browse Connectors before building against a provider.
