# Reddit MCP server for Claude and ChatGPT

Buzzsift is a hosted remote MCP server that lets Claude, ChatGPT, Claude Code or Cursor search Reddit: posts that name a brand or topic, comments that mention it inside other threads, and the busiest threads read in full, each with its subreddit, upvotes, date and link. No Reddit API key, no app to register, nothing to install: add your private address as a custom connector. $1 a search, no subscription.

## What it returns

Up to 150 Reddit posts and comments, most upvoted first: the text, the subreddit or thread it's in, upvotes, date and a link to it.

Tool call: find_mentions {"brand":"Notion","platforms":["reddit"]}

## Setup in Claude

1. **Add it to Claude**: On claude.ai or Claude Desktop, open Customize → Connectors (older versions: Settings → Connectors), press Add, then Add custom connector. Name it Buzzsift and paste https://sociallisteningai.com/mcp as the URL; leave the advanced settings empty. Custom connectors work on every Claude plan, Free included (Free allows one). On Team and Enterprise an owner adds it first.
2. **Sign in and allow**: Press Connect. A Buzzsift page opens: sign in with Google or your email (a new account comes with 100 points, one search) and press Allow. You go back to Claude, connected.
3. **Ask**: "What do people complain about with Owala bottles?" Claude calls find_mentions, reads the posts and answers with links; ask for "a full report" to get the finished report.

## Setup in ChatGPT

1. **Open Plugins**: On chatgpt.com (web), open Plugins in the sidebar, press the + button and choose "Add custom MCP server". Tested on a Plus account on November 14, 2026; on Business and Enterprise an admin may have to allow custom servers first.
2. **Add the server**: Name it Buzzsift, paste https://sociallisteningai.com/mcp as the Server URL, set Authentication to OAuth, tick "I understand and want to continue" and press "Create as a plugin", then Connect: sign in to Buzzsift and press Allow.
3. **Use it in a chat**: In a chat, type @ and pick Buzzsift, then ask about a brand. Searches and reports spend points, so ChatGPT asks before a full report.

- **Claude Code**: In a terminal: claude mcp add --transport http buzzsift https://sociallisteningai.com/mcp, then /mcp in Claude Code to sign in.
- **Cursor**: Settings → MCP → Add new MCP server, or in ~/.cursor/mcp.json: {"mcpServers": {"buzzsift": {"url": "https://sociallisteningai.com/mcp"}}}; Cursor opens the sign-in page.
- **Other MCP clients**: Any client that connects to a remote MCP server over Streamable HTTP with OAuth: use https://sociallisteningai.com/mcp. A client without OAuth can use a private address from your account page instead (it carries the key; no sign-in).

## Questions

**Do I need Reddit API credentials?** No. It reads public posts and comments; you don't register a Reddit app or log in.
**How is it different from the open-source Reddit MCP servers?** Those you run yourself with your own Reddit API credentials. This one is hosted: paste an address and it works in Claude, ChatGPT, Claude Code and Cursor. The trade-off is that each search costs points.
**Can it post, vote or read private subreddits?** No. It only reads public posts and comments.
