const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const deployed = await pd.triggers.deploy({
  id: "linear-comment-created-instant",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    linear: { authProvisionId: "apn_xxxxxxx" },

})

console.log(deployed.id)
```

```

**MCP**

MCP servers expose Linear actions as on-demand tools.

New Comment Created (Instant) is an event source, so your application deploys it with the Connect SDK or API and then either receives each event at a webhook URL or retrieves events on demand with the trigger events API.

## Event delivery

Every event is sent to the HTTP endpoint you choose when you deploy the source. Or: no webhook required — your app or agent can fetch recent events from the [trigger events API](https://pipedream.com/docs/connect/api-reference/list-trigger-events.md) instead.
