## Description

Lists the departments configured in the Brex account with their ID and name. Results are capped at `maxResults` (default `100`) — check `$summary` for a truncation notice and raise `maxResults` if it's truncated. This is how you turn a department name into the department ID that **Invite User** requires. [See the documentation](https://developer.brex.com/openapi/team_api/departments/listdepartments)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `maxResults` | `integer` | No | The maximum number of records to return, from 1 to 2000. Defaults to 100. |

## Run it

**MCP**

```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": "brex",
      },
    },
  },
)

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

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
  name: "brex-list-departments",
  arguments: {
    maxResults: 10,
  },
})
```

**TypeScript**

```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 result = await pd.actions.run({
  id: "brex-list-departments",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    brex: { authProvisionId: "apn_xxxxxxx" },
    maxResults: 10,
  },
})

console.log(result)
```
