OpenConnector
An open-source connector gateway that lets AI agents and applications reach more than a thousand SaaS providers and prebuilt actions through an SDK, CLI, MCP, HTTP or OpenAPI.
OpenConnector is a connector gateway for AI agents, positioned as an alternative to Pipedream and Composio. A user connects an app account once, and the gateway exposes a shared catalog of providers and prebuilt actions to agents and applications through the Connector SDK, an oo CLI relay, MCP, HTTP/OpenAPI, or a web console.
It can run as a managed, hosted runtime with OAuth already set up, or self-hosted with Docker or Node.js on infrastructure a user controls. It handles credentials for API keys, OAuth2, custom credentials and no-auth providers, keeps Action contracts inspectable with request/response schemas and required scopes, and offers runtime controls for connection identity, scopes, tokens, allow/block policies and redacted run logs.
It is written in TypeScript, stores state in SQLite or PostgreSQL with local or S3-compatible file transit, and is licensed under Apache-2.0.
