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 no key, and returns one row layout for all of them. 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:

{
  "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."
