Overview

AI-generated overview

Lets an assistant find subreddits relevant to a product or niche and see how often AI answer engines cite them.

What you can do
The server exposes two tools. find_subreddits takes a short description of a product, brand or niche and returns up to 10 matching subreddits, closest match first. get_subreddit takes a subreddit name and returns its AI citations by engine, the kinds of questions involved, and which threads are cited most.
When to use it
Useful when planning Reddit community outreach or checking whether a particular subreddit matters for being recommended by ChatGPT, Perplexity or Gemini. It fits questions about where AI answers look for recommendations in a category.
Requirements
A remote MCP endpoint at communitymentions.com, reached over streamable HTTP. No packages, environment variables or headers are declared, and no authentication is declared.
Before you install
Queries describe your product, brand or niche and the subreddits you look up, and are sent to a third-party service. Citation figures are that service's own measurements, so treat them as estimates rather than verified data.

Installation

In SourceWeft

  1. Open CommunityMentions in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.communitymentions%2Fcommunitymentions/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Tools

find_subreddits

Find subreddits for a product

Use this when someone asks which subreddits or Reddit communities fit a product, brand or niche, or where on Reddit AI answers look for recommendations in a category. Takes a short description such as "AI writing tool for marketers" and returns up to 10 matching subreddits, closest match first, with how often AI answers cited each, members and a link to each subreddit's data page. Only subreddits in CommunityMentions' data (cited 50+ times or with 50+ verified comments placed) are included; health, legal-help and adult communities are left out.

Parametersdescriptionrequired

get_subreddit

Get a subreddit's AI-citation data

Use this when someone asks how often AI answers cite a specific subreddit, which of its threads get cited, or whether it matters for being recommended by ChatGPT, Perplexity or Gemini. Takes a subreddit name such as "SaaS" or "r/marketing" and returns its AI citations by engine, the kinds of questions those answers were about, its most-cited threads and its member count.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
