An MCP server that resolves a company domain to its subreddit and samples public mentions of the brand. It wraps the Mamba Labs Reddit Brand Presence and Mention Monitor actor on Apify and returns a Clay-ready flat JSON row to any MCP client.

What it does

Give it a company domain and it returns that company's subreddit, how alive that subreddit is, and a sample of how much the brand is being talked about across Reddit as a whole. One flat row per company, covering the subreddit URL, subscriber count, posting cadence and a mention sample.

Read this limitation before you build on it. Reddit's RSS routes returned HTTP 403 to Apify platform IP ranges as measured on 2026-08-22, and Reddit returns 403 on every unauthenticated JSON route. Subreddit discovery resolves, but cadence and mention fields can come back marked blocked rather than populated. A refusal is reported as blocked and never as a zero, so an absence is never mistaken for a finding. Supplying your own Reddit app client id and secret is the only route to a subscriber count.

All of the lookup runs on Apify. This package is a thin client that calls the actor and hands back the result unchanged.

Quick start

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

Add this to your Claude Desktop config:

{
  "mcpServers": {
    "mamba-reddit-brand-presence-mapper": {
      "command": "npx",
      "args": ["-y", "@mambalabsdev/mcp-reddit-brand-presence-mapper"],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Get your token at https://console.apify.com/account/integrations, paste it in, and restart Claude Desktop. The mapredditbrand_presence tool will be available.

Prerequisites

• Node.js 18 or newer
• An Apify account with an API token
• Optional: your own Reddit app client id and secret, free to create at reddit.com/prefs/apps, if you want the subscriber count
