Questions about the Reddit MCP
Do I need Reddit API keys?
No. Manifold is hosted and reads Reddit through a data provider, so there is no Reddit app to register and nothing to install.
Can my agent post, comment or vote?
No. Every tool is read-only. Your agent finds and reads threads; you decide where to join in.
Is Reddit search complete?
No. Search is ranked, like Reddit’s own, and never returns everything. To see everything posted in a community, ask for its new posts: that tool returns the whole time window and says how much it covered. Reddit tools in the docs
Which clients does it work with?
Claude, Claude Code, ChatGPT, Codex, Cursor, Gemini CLI, Grok, OpenCode and any other client that connects to a remote MCP server. Sign in with OAuth, or use an API key from the dashboard for scripts. Setup guides for every client
Can it find threads that ChatGPT and Google cite?
Yes, with the other tools on the same server. The AI visibility tools show which pages AI answers cite, and Reddit threads are often among them. AI visibility MCP
