OpenConnector is an open-source connector gateway for AI agents and an alternative to Pipedream/Composio. Connect user app accounts once, then expose a shared catalog of 1,000+ providers and 10,000+ prebuilt Actions to agents and applications.

| Managed OAuth and hosted runtime, ready to use. No deployment or OAuth app setup. | Run locally or on your own infrastructure with Docker or Node.js. You manage storage and OAuth apps. | Cloudflare, Fly.io, RepoCloud, nibrun, NEXUS AI, Pethost, ZopDay, and more. |
| 🚀 OOMOL Hosted | Self-host | More platforms |
Use the Connector SDK from app code, oo CLI as the local-agent relay, MCP from agent hosts, HTTP/OpenAPI from custom clients, and the Web Console for administration and debugging.
- Keep credentials, scopes, schemas, policies, and run logs inside an inspectable runtime.
- Run locally, on your own infrastructure, or through OOMOL's hosted runtime.
- Use the same provider ids, Action ids, schemas, and contracts across open-source and commercial SaaS deployments.
- A working connector catalog across products such as GitHub, Gmail, Notion, BigQuery, Google Analytics, Supabase, Airtable, Slack, and more.
- Credential handling for API keys, OAuth2, custom credentials, and no-auth providers.
- Built-in OAuth 2.1 authorization server so remote MCP clients and other agents can authenticate with dynamically registered clients, PKCE S256, and revocable, policy-scoped access tokens.
- Inspectable Action contracts: request/response schemas, required scopes, and lazy-loaded executor source.
- Runtime controls for connection identity, scopes, runtime tokens, action allow/block policies, temporary file transit, and redacted run logs.
- Deployment options for local Docker or Node.js with SQLite or PostgreSQL state and local or S3-compatible transit storage, plus OOMOL's hosted runtime. Additional managed platforms are listed in deployment options.
OpenConnector fits products where agents need durable access to the tools users already use, without handing provider credentials to the agent process.
- Agent products that need reusable access across work apps, developer tools, data systems, communication platforms, and AI services.
- Products adding agent workflows that need stable, inspectable Action contracts for user app access.
- Teams that want hosted auth for speed while keeping a path to private or self-hosted runtime control.
| Tool | Purpose |
|---|---|
| Connector SDK | Thin TypeScript HTTP client. Use OpenConnector for self-hosted runtimes, or Connector / ProjectConnector for OOMOL-hosted personal and SaaS end-user connections. |
| oo CLI | Local agent relay for connector Actions. oo connector can search, inspect, and run Actions against OOMOL-hosted or self-hosted OpenConnector runtimes. |
| MCP | Expose app Actions to MCP-capable agent hosts through http://localhost:3000/mcp. |
| HTTP / OpenAPI | Call /v1/actions/* directly or inspect the generated /openapi.json document. |
Endpoint details, response envelopes, auth headers, MCP tools, and Action guide examples are in docs/runtime-api.md.
OpenConnector ships with a local Dashboard for browsing connectors, configuring credentials, creating runtime tokens, and inspecting runtime usage.
Use the connector catalog to see available services, search for providers, and open their Actions and credential setup from one place.
Use the Overview page after deployment to monitor runtime readiness, available providers, executable Actions, recent failures, tool call trends, and recent calls.
Provider names and trademarks belong to their respective owners and are used only for identification and interoperability.

Apps and agents discover Actions, inspect schemas and scopes, select a connection alias, and execute through the gateway. Provider secrets stay behind the runtime boundary; agents receive the metadata, safe account labels, and execution results needed for the run.
| Path | Best for | Includes |
|---|---|---|
| Open-source self-host | Developers and teams that want full control | Local Docker or Node runtime, SQLite or PostgreSQL state, local or S3-compatible transit files, MCP, HTTP, OpenAPI, and Web Console |
| Kubernetes (Helm) | Teams that run their own clusters | Hardened Helm chart with PVC-backed SQLite or PostgreSQL plus migration hooks, Ingress, autoscaling, and NetworkPolicy toggles |
| OOMOL | Teams that want users to authorize accounts immediately | OOMOL-provided OAuth apps, monthly included Connect credits, and hosted runtime infrastructure; the same provider and Action contracts keep a path open to later private or self-hosted deployment |
Note
This starts a self-hosted runtime. OAuth providers require OAuth client credentials from apps you register with those providers. To let users authorize supported providers without setting up your own OAuth apps, use OOMOL-hosted connectors.
Start the runtime from the published image with Docker Compose:
docker compose upThis pulls ghcr.io/oomol-lab/open-connector:latest. To build from source instead:
docker compose -f docker-compose.yml -f docker-compose.build.yml up --buildOpen the local console and generated API reference:
http://localhost:3000
http://localhost:3000/docs
Run a no-auth Action to verify the runtime:
curl -s -X POST http://localhost:3000/v1/actions/hackernews.get_top_stories \
-H 'content-type: application/json' \
-d '{"input":{}}'See docs/quickstart.md for the full local setup, first provider connection, OAuth flow, and runtime settings.
GitHub is the simplest credentialed example because it can use a personal access token:
curl -s -X PUT http://localhost:3000/api/connections/github \
-H 'content-type: application/json' \
-d '{"authType":"api_key","values":{"apiKey":"github_pat_..."}}'
curl -s -X POST http://localhost:3000/v1/actions/github.get_current_user \
-H 'content-type: application/json' \
-d '{"input":{}}'A GitHub App installation works the same way with no token to paste: store the App ID, the
installation id and the App's private key, and the runtime mints one-hour installation tokens on
demand. The connection profile identifies the installation's account; get_current_user requires
a personal access token or OAuth user credential. Installation repository listing supports
pagination only; omit visibility, sort and direction.
curl -s -X PUT http://localhost:3000/api/connections/github \
-H 'content-type: application/json' \
-d "{\"authType\":\"custom_credential\",\"values\":{\"appId\":\"1234567\",\"installationId\":\"87654321\",\"privateKey\":\"$(awk 'BEGIN{ORS="\\n"}1' app.private-key.pem)\"}}"For OAuth2 apps, named connections, credential encryption, token refresh, and action policies, see docs/credentials.md and docs/configuration.md.
For npm-based local development, open http://localhost:5173; the Web Console dev server proxies
API requests to the runtime on http://localhost:3000. For Docker or a built Node runtime, the
console is served from http://localhost:3000.
The console supports provider browsing, API key and OAuth client configuration, runtime token creation, Action schema inspection, Action debugging, recent run review, and access to the generated OpenAPI and MCP metadata.
The Node runtime uses SQLite by default and can use PostgreSQL 15 or newer when
OOMOL_CONNECT_DATABASE_URL is configured. PostgreSQL migrations are explicit: run
npm run runtime:migrate before starting a version with pending migrations. Server startup only
checks schema readiness and never applies PostgreSQL DDL. See
docs/configuration.md for configuration, permissions, TLS,
and multi-instance requirements. The Docker image exposes the same runner as its migrate
subcommand; see docs/docker-ghcr.md.
Run OpenConnector from a prebuilt image on GitHub Packages (GHCR): ghcr.io/oomol-lab/open-connector. Use
latest for the newest release, a pinned released version for production, or tip for the latest
main build.
See docs/docker-ghcr.md for tags, pulling, and running.
If you want an AI bot you can use out of the box, try Leina. Leina connects to over 1,500 SaaS apps and lets you customize your own AI agent by choosing its app connections, skills, and knowledge base to fit your team’s workflows.
Use it in Slack, Microsoft Teams, Discord, or Telegram to find information, compile weekly reports, organize customer feedback, and prepare sales follow-ups through the apps you authorize.

npm install
npm run devThe local API runtime listens on http://localhost:3000. The Web Console dev server listens on
http://localhost:5173 and proxies API requests to the runtime.
