B2B Reddit Conversation Monitor MCP Server

Status, 12 November 2026

Working: Reddit threads and comments from the Arctic Shift archive of public Reddit posts (no key, about 15 minutes behind live Reddit), searched in the subreddits you name or 8 default business subreddits. Keyword search across all of Reddit with your own Serper or Brave search key. Hacker News and Product Hunt, unchanged.

Changed: Reddit closed logged-out search around 5 November 2026 and ends RSS on 13 November 2026. Actor version 0.1 read those feeds, so its Reddit searches returned 0 rows from about 5 November. Actor version 0.2 and this server's 1.1.0 read no Reddit feed. What to use instead: name your subreddits, or pass your own key in search_api_key. Pick the route in reddit_route; if it fails, the actor switches to the other route and says so in route_note.

A blocked run charges only the start fee.

An MCP server for the Mamba Labs B2B Reddit Conversation Monitor actor on Apify. Give it a company domain, product category keywords, or a topic. Each run reads public Reddit posts and comments through the route you pick (the Arctic Shift archive with no key, or your own Serper or Brave key) and returns tagged threads and comments, plus summary rows: share of voice against competitors, the most discussed companies in a category, or recurring questions grouped by theme. Every row names its route in data_route.

What it does

Three modes:

company: give company_domain (for example smartlead.ai). You get the threads and comments that name the brand or its competitors, each tagged complaint, praise, comparison, alternative_request, switching, buying_intent, feature_request, or question, with sentiment and a 0 to 100 intent score. A row gets displacement_signal true when one sentence names a competitor and complains about it, switches from it, or asks for an alternative to it. One company summary row carries mention counts, the sentiment split, share of voice per competitor, and the top complaint themes.
category: give category_keywords (for example cold email tools). You get the threads plus one row per company discussed in two or more threads, with mention counts, sentiment, and share of voice.
gap: give subreddits, a topic, or both. You get the questions people ask (is there a tool for, how do I, alternative to), grouped by theme, with how many went unanswered and which tools the answers named.

Reddit routes (reddit_route):

Route	Where Reddit rows come from	Needs	Comments
`arctic_shift` (default)	Arctic Shift, a free public archive of Reddit posts and comments run by an independent open source project	Subreddits; with none named and no key, r/sales, r/SaaS, r/startups, r/Entrepreneur, r/marketing, r/smallbusiness, r/coldemail, r/b2bmarketing	Yes
`search_key`	Your own Serper or Brave key searches `site:reddit.com`; hits are read back through Arctic Shift	`search_api_key`	No
`both`	Both, duplicates removed	Same as above	Arctic Shift rows only

If the route you pick fails (no answer, a timeout, a refused key, a key with no credits), the actor switches to the other route when it can run, and route_note says so. search_key with no key returns one free error row per input that says so, and no other route runs in its place. Each Reddit thread row also gets embed_checked and post_state (live, removed, unknown) from Reddit's public post embed.

Tags, sentiment, and the score are rule based. Blocked or empty results come back free with a row_status saying so. 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-b2b-reddit-conversation-monitor": {
      "command": "npx",
      "args": [
        "-y",
        "@mambalabsdev/mcp-b2b-reddit-conversation-monitor"
      ],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Restart the client. The monitor_reddit_conversations 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 on Reddit saying about smartlead.ai versus Instantly in the last 60 days? Show the displacement signals."
"Which cold email tools get recommended most on Reddit this year?"
"What do people in r/sales and r/LeadGeneration keep asking for that nobody answers?"

Tool

monitor_reddit_conversations. One tool. Example arguments:

{
  "mode": "company",
  "company_domain": "smartlead.ai",
  "brand_names": ["Smartlead"],
  "competitors": ["Instantly", "lemlist"],
  "since_days": "60"
}

A blocked run charges only the start fee. Blocked, error, and no results rows, and rows skipped by only_new, are free. A row found through a fallback route costs the same as any row; the route that failed costs nothing.

Your keys

The actor needs no key. With no key it reads Reddit through Arctic Shift. A Serper or Brave key of your own (search_api_key) adds keyword search across all of Reddit and a fallback route; you pay the search service for its calls, and the actor's prices do not change. Exa is not offered: it returns no reddit.com pages. The actor holds no key of its own; your key is passed to your own Apify run, marked secret, and never written to a row, a log, or the run summary. The search key route was tested with recorded answers and with refused keys; your first run with your key is its live test. Proxy traffic adds nothing to your price: Mamba Labs pays the platform costs of the run. proxy_mode is a reliability setting for Product Hunt only.

FAQ

Why did Reddit results stop in early November 2026? Reddit closed logged-out search around 5 November 2026 and ends RSS on 13 November 2026. Actor version 0.2 (12 November 2026) reads Arctic Shift and your own search key instead.

Do I need a key? No. Name your subreddits, or 8 default business subreddits are searched. A key adds search across all of Reddit.

What does a blocked run cost? Only the start fee.

Why does a post read [removed]? Arctic Shift stores a post when it is made. post_state shows its state on Reddit at run time.
