MCP
One MCP session, both toolsets
One session gives your product or agent every Harvest and LinkedIn 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": "harvest,linkedin",
},
},
},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// One list, both toolsets: Harvest and LinkedIn tools arrive
// together, each keyed by its own app's slug.
// e.g. run Create Invoice:
const result = await mcp.callTool({
name: "harvest-create-invoice",
arguments: {
accountId: "Account ID",
clientId: "Client ID",
},
})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 [harvestTools, linkedinTools] =
await Promise.all([
pd.components.list({ app: "harvest" }),
pd.components.list({ app: "linkedin" }),
])
// One external user owns both connected accounts, so either app's tools
// run on their behalf with the same externalUserId.curl "https://api.pipedream.com/v1/connect/{project_id}/components?app=harvest" \
-H "X-PD-Environment: production" \
-H "Authorization: Bearer {access_token}"
curl "https://api.pipedream.com/v1/connect/{project_id}/components?app=linkedin" \
-H "X-PD-Environment: production" \
-H "Authorization: Bearer {access_token}"
# 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.

-
Create Invoice
actionCreate a new free-form invoice for a client. Provide Line Items as a JSON array to itemize the invoice. Example: call with clientId set to InGen Corp's client ID, subject="Consulting Services", lineItems=[{"kind":"Service","description":"Genetics consulting","unit_price":2000,"quantity":1}]. See the documentation.Writev0.0.1 -
Create Project
actionCreate a new project. Example: call with clientId set to InGen Corp's client ID, projectName="Compound Perimeter Fence Upgrade", isBillable=true, billBy="Project", budgetBy="none". See the documentation.Writev0.0.1 -
Create Task Assignment
actionAssign a task to a project. Use Get Projects to find a project ID and List Tasks to find a task ID. Example: call with projectId set to the Jurassic Park Construction project's ID and taskId set to the Genetics Research task's ID to put that task on the project. See the documentation.Writev0.0.1 -
Create Timesheet Entry
actionCreate a new time entry. Two ways to log time, matching the account's Company setting: on duration-based accounts (wants_timestamp_timersisfalse— the common case) set Hours to log a completed entry directly. On timestamp-based accounts (wants_timestamp_timersistrue) leave Hours blank and use Started Time/Ended Time instead — leave both time fields blank too to start a running timer now, or set both to log a completed entry with explicit start/end times. Passing Started/Ended Time on a duration-based account is silently ignored by Harvest (it starts a running timer instead) — if that happens, switch to Hours. Use Get Projects to find a Project ID, List Tasks to find a Task ID, and List Users to find a User ID. Example (duration-based): call with projectId, taskId, spentDate="2026-09-17", hours=3.5. Example (timestamp-based): the same call with hours omitted and startedTime/endedTime set instead. See the documentation and start/end time variant.Writev1.0.0 -
Create User

Create User Assignment

Delete Invoice
actionPermanently delete an invoice. Use List Invoices to find a valid ID. Example: call with invoiceId set to a draft invoice's ID to remove it before it's sent. See the documentation.Writev0.0.1 -
