## Description

List the comments and nested replies on a specific Reddit post. Use this after locating a post via **List Subreddit Posts** when you need its discussion thread. Provide the full post URL (e.g. `https://www.reddit.com/r/pics/comments/abc123/title/`). Enable **Trim** for a lighter response shape, and page through long threads with the cursor. [See the documentation](https://app.socialfetch.dev/playground?path=/v1/reddit/posts/comments&method=GET)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `url` | `string` | Yes | Link to the Reddit post (string, https://). E.g. https://www.reddit.com/r/pics/comments/abc123/title/. |
| `trim` | `boolean` | No | When enabled, requests a lighter response shape when available. |
| `cursor` | `string` | No | Pagination cursor from a previous response (data.page.nextCursor). |

## 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": "social_fetch",
      },
    },
  },
)

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: "social_fetch-list-reddit-post-comments",
  arguments: {
    url: "Post URL",
    trim: true,
  },
})
```

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: "social_fetch-list-reddit-post-comments",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    social_fetch: { authProvisionId: "apn_xxxxxxx" },
