## Description

Retrieve a collection by ID. Returns the collection's description, a lightweight article list (id, name, slug), and parent/child collection group relationships for hierarchy navigation. To find a collection ID: run **Search Publication** — each result includes `collections[].id`, or call **Get Article** and extract `collections[].id`. To get full content for a listed article, pass its `id` to **Get Article**. [See the documentation](https://docs.polly.help/integrations/a/publication-api-examples?partition=3iD5jyfMSRprgo2tD)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `collectionId` | `string` | Yes | The ID of the collection to retrieve. To find a collection ID, run Search Publication and extract collections[].id from any result, or call Get Article and extract collections[].id from the article. |

## 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": "polly_help",
      },
    },
  },
)

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: "polly_help-get-collection",
  arguments: {
    collectionId: "Collection ID",
  },
})
```

**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: "polly_help-get-collection",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    polly_help: { authProvisionId: "apn_xxxxxxx" },
    collectionId: "Collection ID",
  },
})

console.log(result)
```
