FAQ
Common questions
Can I use Reddit MCP without a developer API key?
Yes for the core browser workflow. You still need to sign in to your own Reddit session and follow Reddit's policies.
Can Claude Desktop or Codex publish to Reddit?
Yes, with a locally configured MCP client and authenticated browser session. Review the preview and approve the consequential action.
Can I publish without Chrome?
No. Chrome/Chromium is required for login, live browser previews and writes. LightPanda may be used for supported reads.
Will a subreddit always accept my post?
No. Subreddit rules, account restrictions, moderation and changes to the Reddit UI can interrupt publication.
Do I need to share my Reddit password with an AI?
No. Sign in through your own browser, keep credentials and keys private, and protect your server.
