## Description

List a project's area or iteration path tree. Returns the node tree with each node's name and full path. Use this to discover the values the **Area Path** and **Iteration Path** inputs of the work item actions expect - those inputs want the backslash-delimited path, not the node name. Example: structure group `Iterations` returns `Fabrikam-Fiber-Git\\Sprint 1`. [See the documentation](https://learn.microsoft.com/en-us/rest/api/azure/devops/wit/classification-nodes/get?view=azure-devops-rest-7.1)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `organization` | `string` | Yes | Name of the organization Options are loaded from the connected account. |
| `project` | `string` | Yes | Project ID or project name. Run the List Projects action first to obtain valid values. |
| `structureGroup` | `string` | Yes | Which tree to return |
| `depth` | `integer` | No | How many levels of children to fetch (max 10). Defaults to 2. |

## 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": "azure_devops",
      },
    },
  },
)

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: "azure_devops-list-classification-nodes",
  arguments: {
    organization: "Organization",
    project: "Project",
  },
})
```

**TypeScript**

})

const result = await pd.actions.run({
  id: "azure_devops-list-classification-nodes",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    azure_devops: { authProvisionId: "apn_xxxxxxx" },
