Auto-posting must comply with Reddit's Responsible Builder Policy. Default mode is MANUAL — auto mode requires double confirmation.. Hosted by 0n3: 21 endpoints your AI can call with your own Reddit account, from Claude, ChatGPT, Cursor, Claude Code, Codex or Gemini CLI. One sign-in, one key per AI, a receipt for every call.

Install in three steps

  1. Create a free account at 0n3.app and connect Reddit: paste a key or sign in through a door. It lands in your vault, encrypted.
  2. Open 0n3.app/install, pick your AI. A key is made for that AI alone; copy the line it gives you.
  3. Ask your AI: whoami. It answers with your connected services. Then ask it to submit post in Reddit.

Questions

What can an AI do with the Reddit MCP server?

21 things: posts, comments, subreddits, messages and more. Every call runs with your own Reddit connection and lands on a receipt.

Do I need to run anything on my computer?

No. 0n3 is hosted. Connect Reddit once, install 0n3 into your AI with one line, done.

Where does my Reddit key go?

Into your 0n3 vault, encrypted, one record per connection. The AI never sees it.
