Overview

AI-generated overview

Searches public posts and comments on Bluesky, Hacker News, Mastodon, Lemmy, Reddit and YouTube and returns them in one row layout.

What you can do: Search public posts by keyword across six platforms, or read comments on given post addresses
Filter by platform, date, post and comment limits, and Mastodon or Lemmy instance
Choose how Reddit is reached: the Arctic Shift archive by subreddit, your own Serper or Brave key, or both
Get a free status row per query and platform explaining what was returned or blocked
Cap spending with a maximum charge amount per run
When to use it: Useful when you want an assistant to gather public discussion on a topic or the comments under specific posts across several platforms and compare them in one table, for example sentiment or feedback research.
Requirements: Runs locally as an npm package via npx, needing Node.js 18 or newer. Requires an Apify account and an Apify API token set as APIFY_TOKEN; the tool is listed without a token but calls need one. Searching all of Reddit by keyword additionally needs your own Serper or Brave key.

Before you install

Runs are billed per post or comment row plus a start fee to your Apify account, and each comment is a charged row. A search_api_key is sent to the chosen search provider. The server starts remote Apify actor runs and returns their dataset rows. Instagram, X, Facebook, TikTok and LinkedIn are not covered.

README

Multi Platform Social Posts and Comments MCP Server

[Glama score] [MCP Registry] [npm version] [npm downloads] [license] [mcpservers.org]

An MCP server for the Mamba Labs Multi Platform Social Posts and Comments actor on Apify. Public posts and comments from 6 platforms, in one row layout.

Note to current users, 13 November 2026

Reddit changed how its data can be reached: it closed logged-out search about 5 November 2026 and ended its RSS feeds on 13 November 2026. We rebuilt the actor so it keeps returning Reddit data. It now reads the Arctic Shift archive of Reddit posts, lets you choose the route with reddit_route, and switches to the other route when the first one fails. Add your own Serper or Brave search key to search all of Reddit by keyword. A blocked run charges only the start fee. Your saved inputs and tasks keep working. Prices do not change.

What's Inside

What it does

Give keywords or post addresses. The actor reads public posts and their comments from Bluesky, Hacker News, Mastodon, Lemmy, Reddit, and YouTube, with no login, and returns one row layout for all of them. Reddit is read from the Arctic Shift archive for the subreddits you name, or across all of Reddit with your own Serper or Brave key. A free status row per query and platform says what each returned or why it was blocked. Instagram, X, Facebook, TikTok, and LinkedIn are not covered.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

json

{  "mcpServers": {    "mamba-multi-platform-social-posts-comments": {      "command": "npx",      "args": [        "-y",        "@mambalabsdev/mcp-multi-platform-social-posts-comments"      ],      "env": {        "APIFY_TOKEN": "your-apify-token"      }    }  }}

{  "mcpServers": {    "mamba-multi-platform-social-posts-comments": {      "command": "npx",      "args": [        "-y",        "@mambalabsdev/mcp-multi-platform-social-posts-comments"      ],      "env": {        "APIFY_TOKEN": "your-apify-token"      }    }  }}

Restart the client. The get_social_posts_comments tool appears.

Prerequisites

Node.js 18 or newer.
An Apify API token from console.apify.com/account/integrations, set as APIFY_TOKEN. The server lists its tool without a token; a call needs one.

Example prompts

"What are people saying about CRM migrations on Hacker News and Bluesky?"
"Collect the comments on these post addresses into one table."
"Find recent public posts about cold email deliverability since October."

Tool

get_social_posts_comments. One tool. Example arguments:

json

{  "queries": [    "crm"  ],  "platforms": [    "bluesky",    "hackernews",    "lemmy"  ],  "max_posts_per_platform": 3,  "max_comments_per_post": 2}

{  "queries": [    "crm"  ],  "platforms": [    "bluesky",    "hackernews",    "lemmy"  ],  "max_posts_per_platform": 3,  "max_comments_per_post": 2}

Inputs

Every buyer facing input of the actor. Omitted inputs take the actor's own defaults.

Input	Type	Required	Description
`queries`	array	no	Keywords to search on each platform, up to 20. Mastodon reads a query as a hashtag, so crm tools becomes #crmtools.
`post_urls`	array	no	Addresses of posts to read comments from, such as your own posts, up to 100. Bluesky, Hacker News, Mastodon, Lemmy, Reddit, and YouTube.
`platforms`	array	no	Any of bluesky, hackernews, mastodon, lemmy, reddit, youtube. Default all 6. Used for queries; a post address picks its own platform.
`max_posts_per_platform`	number	no	Up to 500. Default 25. YouTube returns its first results page, about 20 videos.
`include_comments`	boolean	no	yes or no. Default yes. Each comment is a charged row.
`max_comments_per_post`	number	no	Up to 200. Default 20. YouTube returns its first comment page, about 20.
`since_date`	string	no	Only posts from this date, such as 2026-10-01. YouTube gives relative dates only, so YouTube rows are not filtered.
`mastodon_instance`	string	no	Host name to read hashtags from. Default mastodon.social.
`lemmy_instance`	string	no	Host name to search. Default lemmy.world.
`reddit_subreddits`	array	no	Subreddits to search for each query on Reddit, such as sales or r/sales, up to 10. Without your own search key, Reddit is searched through the Arctic Shift archive, which needs a subreddit. Leave empty to search all of Reddit with `search_api_key`.
`reddit_route`	string	no	`arctic_shift` (default): the Arctic Shift archive, free, needs `reddit_subreddits`. `search_key`: your own Serper or Brave key, searches all of Reddit. `both`: both, deduped. When the chosen route fails or cannot run, the actor uses the other one if it can and says so in `route_note`.
`search_provider`	string	no	`serper` or `brave`, the provider of `search_api_key`. Default `serper`.
`search_api_key`	string	no	Optional. Your own Serper or Brave Search key, used only to find Reddit posts across all of Reddit. Sent only to that provider, never logged or written to a row.
`max_charge_usd`	string	no	Optional. The run stops before a charge that would pass this amount. Summary rows are always returned.

Pricing

Pay per event on Apify, billed to your Apify account. Prices in USD.

Platform status rows and refused input are free, and a blocked run charges only the start fee. Mamba Labs pays the platform costs of the run, Apify proxy traffic included. Search calls made with your own key are billed to you by your provider.
