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 refuses a share of requests however they are routed. Measured on the platform 2026-08-23 across nine companies over residential connections, the subreddit feed was readable for four and refused for five, and the mention feed the same. The public .rss feeds are the only open route; Reddit returns 403 on every unauthenticated JSON route. A refusal is reported as blocked and never as a zero, so an absence is never mistaken for a finding, and a blocked row is worth retrying. 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 map_reddit_brand_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

Example prompts

• "Find the subreddit for monzo.com and tell me how active it is."

• "Map the Reddit presence for stripe.com and search mentions for "stripe.com" rather than the brand name."

• "Look up r/monzo and skip the site wide mention sample."

• "Is there an official subreddit for figma.com?"

Inputs

• company_domain (optional): bare company domain, for example shopify.com. Supply this or a handle. With a domain the actor runs full discovery; with a handle it skips straight to the fetch.

• company_name (optional): improves search accuracy and is what the identity gate checks a discovered profile against, so supplying it reduces wrong matches.

• handle (optional): the subreddit name with or without the r/ prefix, for example stripe. Supplying it skips discovery.

• mentionQuery (optional): what to search Reddit for when measuring brand mentions. Defaults to your domain in quotes, which is far more precise than the brand name. A bare search for stripe matches the English word; "stripe.com" returns developer subreddits.

• includeMentions (optional): when true (the default) a site wide mention sample is pulled alongside the subreddit. Set false for the official subreddit only, which is one fetch instead of two.

• includeFollowerCounts (optional): when true (the default) the profile is fetched and the counts are extracted. Set false to resolve the profile URL only, which is cheaper and needs no proxy.

• skipCache (optional): when false (the default) a successful lookup is cached for seven days and reused. Set true to force a fresh fetch.

• redditClientId (optional): your own Reddit app client id, free to create at reddit.com/prefs/apps. This is the only route to a subscriber count, because Reddit returns 403 on every unauthenticated JSON route. Leave it empty and everything else still works.

• redditClientSecret (optional): your own Reddit app client secret, paired with the client id above. Used for your run only and never stored.

• max_charge_usd (optional): spending cap for this call, in USD. The actor stops before any charge that would take the run past this amount and keeps every row already charged.

Supply either company_domain or handle.

Output

The tool returns the actor's flat JSON row for the company, with 26 snake_case fields and no nested objects. subreddit_status, subreddit_subscribers_status and mentions_status are separate, so a blocked read is distinguishable from an empty one. See the Apify Store page for the full output schema.
