MCP

One MCP session, both toolsets

One session gives your product or agent every Google Sheets and lemlist 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": "google_sheets,lemlist",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// One list, both toolsets: Google Sheets and lemlist tools arrive
// together, each keyed by its own app's slug.

// e.g. run Add Single Row:
const result = await mcp.callTool({
  name: "google_sheets-add-single-row",
  arguments: {
    drive: "Drive",
    sheetId: "Spreadsheet ID",
  },
})

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.
