How to Give Claude Access to Reddit (MCP Setup Guide)

Connect Claude to a Reddit API over MCP and it can search, paginate, and pull comment trees itself. Run one command in Claude Code, or add one JSON block to Claude Desktop's config — either way it takes under five minutes, and Claude can then search Reddit inside the conversation you're already having.

How do I get a ThreadSnoop API key?

Sign up for $0.50 of free credit — 333 reads, no card required — then create a key from /developer. Reads are $1.50 per 1,000 (as low as $1.00/1,000 in bulk).

How do I connect Claude Code to Reddit?

claude mcp add --transport http threadsnoop https://api.threadsnoop.com/mcp \
  --header "x-api-key: YOUR_KEY"

That's the whole setup. Start a session and ask Claude to search Reddit — it now has the tools to do it.

How do I connect Claude Desktop to Reddit?

Desktop only launches local commands, so reaching a hosted MCP server goes through the mcp-remote bridge. Add this to claude_desktop_config.json and restart Desktop:

{
  "mcpServers": {
    "threadsnoop": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.threadsnoop.com/mcp",
        "--header",
        "x-api-key:YOUR_KEY"
      ]
    }
  }
}

A tools icon appears in the composer once it connects — Claude can now see search_posts, search_comments, get_comment_tree, search_subreddits, get_subreddit_rules, and check_credits. Any other MCP client that supports streamable HTTP with custom headers connects the same way — nothing here is Claude-specific.

What can I ask Claude to do with Reddit access?

• “Find threads from this week in r/smallbusiness where people complain about invoicing software.” Claude calls search_posts with the subreddit, a 7-day window, and a q phrase, then reads the bodies and hands back the ones that read like real pain.
• “Has anyone in r/SaaS complained about [competitor] this month, and why?” It searches posts, then calls get_comment_tree on each to read the replies — where the real complaints usually live.
• “Pull the comment tree on this thread and tell me if anyone here would want X.” Paste a URL; Claude extracts the post ID and reasons over the whole discussion, not just the title.
• “Check r/webdev's self-promotion rules before I reply.” One call to get_subreddit_rules — worth doing before you mention your own product anywhere.

Each search or fetch costs 1 credit; check_credits doesn't. Posts under ~36 hours old show a placeholder score and comment count in Reddit's own archive — get_comment_tree gets you the real count.

Everything here reads Reddit; nothing posts, votes, or DMs — the API is read-only, so there's no tool call that would let Claude act on your behalf. If it drafts you a reply, that's a message, not a tool call, and you post it yourself.
