Do I need a Reddit API key or developer app?

No. You only need a Reddinbox API key. Reddinbox runs the Reddit search on its side, so you never register a Reddit app or manage Reddit credentials.

Does the Reddit MCP return full comment threads?

Yes. get_thread takes a Reddit thread URL and returns the post with its nested comment tree. search_threads returns matching posts with links you can pass to get_thread.

Can I write to Reddit with it?

No. The Reddinbox MCP is read-only. It searches and reads public conversations. It does not post, vote or comment.

Is the Reddit MCP available on the free trial?

Yes. Reddit and Hacker News are included during the free trial. Usage counts against the trial token budget.

How is this different from open-source Reddit MCP servers?

Open-source servers run on your machine and use your own Reddit access. Reddinbox is hosted, filters spam and AI-generated posts, and searches other platforms too. Self-hosting gives you more control. Hosted saves you the setup.
