# Orbit + Stack Exchange (Stack Overflow) — Pipedream Connect

> Connect a user's Orbit and Stack Exchange (Stack Overflow) accounts and expose tools for both apps directly in your product or your agent.

- Apps: Orbit (`orbit`) + Stack Exchange (Stack Overflow) (`stack_exchange`)
- This page (HTML): https://pipedream.com/apps/orbit/integrations/stack-exchange
- One `external_user_id` owns both connected accounts, and each account stays independently revocable.

## One session, both toolsets (recommended)

- Endpoint: `https://remote.mcp.pipedream.net/v3`
- Headers: `Authorization: Bearer <token>` · `x-pd-project-id` · `x-pd-environment` · `x-pd-external-user-id` · `x-pd-app-slug: orbit,stack_exchange`
- `x-pd-app-slug` takes a comma-separated list, so `orbit,stack_exchange` is one session on one transport. Both toolsets arrive from a single `listTools()`, and a tool is called exactly as it would be in a single-app session.

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
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 accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,
        "x-pd-project-id": process.env.PIPEDREAM_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": "orbit,stack_exchange",
      },
    },
  },
)

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

const { tools } = await mcp.listTools()

// One list, both toolsets: Orbit and Stack Exchange (Stack Overflow) tools arrive
// together, each keyed by its own app's slug.

// e.g. run Create Activity:
const result = await mcp.callTool({
  name: "orbit-create-activity",
  arguments: {
    workspaceSlug: "Workspace Slug",
    workspaceMemberSlug: "Workspace Member Slug",
  },
})
```

## Both apps from your backend

```ts
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 [orbitTools, stackExchangeTools] =
  await Promise.all([
    pd.components.list({ app: "orbit" }),
    pd.components.list({ app: "stack_exchange" }),
  ])

// One external user owns both connected accounts, so either app's tools
// run on their behalf with the same externalUserId.
```
