## Description

Download the content of a Slack file (e.g. an image, PDF or snippet shared in a channel) to the file-stash directory, returning the saved path plus the file metadata (`name`, `mimetype`, `size`). Canvases download as HTML. Get the file ID from a message's `files[].id` via **Get Channel History**, or from **List Files** / **Browse Files**. Works for files in private channels the authenticated user is a member of. Example: passing `file` `F0123456789` downloads `diagram.png` to `/tmp/F0123456789-diagram.png` and returns `{ "filedata": ["F0123456789-diagram.png", "/tmp/F0123456789-diagram.png"], "file": { "id": "F0123456789", "name": "diagram.png", "mimetype": "image/png", "size": 84213 } }`. [See the documentation](https://docs.slack.dev/reference/objects/file-object#access)

## Props

| Prop | Type | Required | Description |

| `file` | `string` | Yes | The file's ID (e.g. F1234567890). Run Get Channel History (a message's files[].id), List Files or Browse Files first to obtain it. |
| `syncDir` | `dir` | Yes | SyncDir |

## 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": "slack_v2",
      },
    },
  },
)

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: "slack_v2-download-file",
  arguments: {
    file: "File ID",
    syncDir: "SyncDir",
  },
})
```

**TypeScript**

  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "slack_v2-download-file",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    slack_v2: { authProvisionId: "apn_xxxxxxx" },
    file: "File ID",
    syncDir: "SyncDir",
