SDK And CLI

OpenConnector can be used directly through MCP and HTTP, and it also has dedicated developer tools for application and agent workflows. The Connector SDK and oo CLI both work with the open-source runtime and with OOMOL-hosted connector services, using the same provider ids, Action ids, and schemas.

Connector SDK

Connector SDK is the TypeScript client for calling connector Actions from apps and agent runtimes. Use it when you want to execute Actions, proxy upstream provider APIs, or inspect the runtime catalog from code.

Install:

npm install @oomol-lab/connector

For the self-hosted OpenConnector runtime, use OpenConnector. baseUrl is the server origin, not a /v1 URL:

import { OpenConnector } from "@oomol-lab/connector";

const open = new OpenConnector({
  baseUrl: "http://localhost:3000",
  runtimeToken: process.env.OOMOL_CONNECT_RUNTIME_TOKEN,
});

const stories = await open.hackernews.get_top_stories({});
console.log(stories);

For OOMOL-hosted connector services, use Connector for personal connections or ProjectConnector for end-user connections in a SaaS product. All clients use the same Action model; the gateway keeps provider credentials behind the runtime boundary, authorizes the request, and executes the provider Action. The SDK is intentionally just a client: it does not run provider integrations locally or manage OAuth setup.

For an end-to-end Gmail OAuth and SDK example, see gmail-oauth-sdk.md.

oo CLI

oo CLI is the command-line toolkit for local AI agent workflows. Use it when you want an agent on your machine to discover, inspect, and call connector Actions through a consistent command-line entry.

Point connector-family commands at a self-hosted OpenConnector runtime:

oo connector login http://localhost:3000
oo connector search "send an email"
oo connector schema gmail.send_email
oo connector run gmail --action send_email --data '@payload.json'

For authenticated runtimes, create a runtime token in the Web Console Access page and pass it during login:

oo connector login https://connector.example.com --token <runtime-token>

For containers and CI, use environment variables instead of writing CLI config:

export OO_CONNECTOR_URL="https://connector.example.com"
export OO_CONNECTOR_TOKEN="<runtime-token>"
oo connector run github --action get_current_user --data '{}'

When no self-hosted runtime is configured, connector commands can still route to OOMOL-hosted connector services through OO_API_KEY or the active oo account. A self-hosted connector is a capability override for connector commands, not an oo account; non-connector commands such as hosted LLM, file transfer, and skill publishing still use OOMOL account authentication.

Protocol APIs

For custom clients, scripts, or agent hosts that do not use the SDK or CLI, use:

• MCP: http://localhost:3000/mcp
• HTTP runtime API: /v1/actions
• OpenAPI: /openapi.json

See runtime-api.md for protocol-level details.
