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.
