MCP
One MCP session, both toolsets
One session gives your product or agent every Microsoft Outlook Calendar and Todoist tool at once — connect once, list tools, and call them like any single-app session.
// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(
new URL("https://remote.mcp.pipedream.net/v3"),
{
requestInit: {
headers: {
Authorization: `Bearer ${accessToken}`,
"x-pd-project-id": "{project_id}",
"x-pd-environment": "production",
"x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
"x-pd-app-slug": "microsoft_outlook_calendar,todoist",
},
},
},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// One list, both toolsets: Microsoft Outlook Calendar and Todoist tools arrive
// together, each keyed by its own app's slug.
// e.g. run Accept Event:
const result = await mcp.callTool({
name: "microsoft_outlook_calendar-accept-event",
arguments: {
eventId: "Event ID",
comment: "Comment",
},
})import { PipedreamClient } from "@pipedream/sdk"
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 externalUserId = "{external_user_id}" // any stable ID for this user in your system
const [microsoftOutlookCalendarTools, todoistTools] =
await Promise.all([
pd.components.list({ app: "microsoft_outlook_calendar" }),
pd.components.list({ app: "todoist" }),
])

# Connect both accounts to the same external_user_id, then
# configure and invoke either app's tools on that user's behalf.ARCHITECTURE
One user, two connected accounts
Your user connects each account once, under whatever ID they already have in your product. The two stay independent — either can be revoked on its own — and your code reaches both through that one user.

Triggers
-
Calendar Event Deleted (Instant)
triggerEmit new event when a Microsoft Outlook Calendar event is deleted. Because deleted events cannot be re-fetched from the Outlook API after deletion, this trigger emits notification metadata only (not the full event object). The emitted payload includes the deleted event identifier (eventId),changeType,subscriptionId,tenantId, andnotificationTimestamp. Downstream processors must rely solely on this metadata. See the documentationv0.0.1 -
New Calendar Event (Instant)
triggerEmit new event when a new Calendar event is createdv0.0.16 -
New Calendar Event Update (Instant)
triggerEmit new event when a Calendar event is updatedv0.0.16 -
New Upcoming Calendar Event (Polling)
triggerEmit new event based on a time interval before an upcoming calendar event. See the documentationv0.0.9
TOOLS
Todoist tools
The Todoist tools this pairing puts in reach, each one running on your user's own connected account.

-
New or Modified Task
triggerEmit new event for each new or modified task. See the documentationv0.0.12 -
New Completed Task
triggerEmit new event for each completed Todoist task, including recurring task completions. Non-recurring completions are polled viaGET /tasks/completed/by_completion_date. Recurring completions don't appear there - Todoist reschedules a recurring task instead of marking it completed there - so they're additionally polled via the v1 Activity Log (GET /api/v1/activities), detected as anitem:completedevent withextra_data.is_recurringset totrue. Accessing recurring task completions older than 7 days requires a Todoist premium/business plan. Respects the Projects filter. See the documentation.v2.0.0 -
New Incomplete Task
triggerEmit new event for each new incomplete task. See the documentationv0.1.6 -
New or Modified Project
triggerEmit new event for each new or modified project. See the documentationv0.0.12
