CommunityMentions plugin
Which subreddits AI answers cite, for AI agents (Claude, ChatGPT, Cursor, Grok Build).
This plugin connects your agent to the CommunityMentions MCP server at https://communitymentions.com/api/mcp (streamable HTTP, no sign-in) and adds a skill that tells the agent which tool to use.
Tools
| Tool | What it does |
|---|---|
find_subreddits | Describe a product or niche; get up to 10 subreddits where it fits, with how often AI answers cited each and member counts |
get_subreddit | One subreddit's AI citations by engine (OpenAI models, Perplexity, Gemini), the kinds of questions those answers were about, and its most-cited threads |
The data covers subreddits cited 50+ times in the AI answers CommunityMentions tracks, or where it has placed 50+ verified comments. Read-only.
