RedReplier MCP¶
Remote MCP server (Streamable HTTP, OAuth or API key) - a hosted connector that turns social listening into an agent workflow. RedReplier watches Reddit, Facebook, Hacker News, X and Bluesky for posts that mention your product or keywords, scores each mention 0-100 for lead relevance, and gives your agent the reasoning behind the score plus a drafted reply, so it can surface opportunities before anyone else notices them.
Server type: Remote (Streamable HTTP)
Auth: OAuth sign-in, or API key (redreplier_ prefix) via Authorization header
Endpoint: https://mcp.redreplier.com/mcp
Tools: 6 documented (list_keywords, add_keyword, search_threads, get_thread, get_relevance_score, list_subreddits)

Tools¶
| Tool | Purpose |
|---|---|
| list_keywords | List the keywords RedReplier is tracking for you |
| add_keyword | Start tracking a new keyword, optionally scoped to specific subreddits |
| search_threads | Find Reddit threads matching your keywords, filtered by subreddit, score and recency (minScore, since, limit, offset) |
| get_thread | Fetch the full details and comments of a single thread |

The listing also documents capabilities beyond the six-tool reference - mentions from all five networks in one list filterable by website, source, status or score, a count-before-paging helper, per-mention score reasoning with a saved drafted reply, mention statuses (new, approved, rejected), monitored websites and keywords with cost previews, and email alert digest controls. Connect to discover the full live tool list.
Connection¶
- Create a RedReplier account and add at least one website or keyword set to track.
- Add the endpoint to any MCP client. Claude Code one-liner -
claude mcp add redreplier --transport http https://mcp.redreplier.com/mcp - Sign in when the OAuth browser window opens. For headless agents or clients without OAuth, create an API token at redreplier.com/api-tokens and send it as
Authorization: Bearer redreplier_...(with or without the Bearer prefix). - Ask for today's high-scoring threads about your product, or have the agent triage the mention inbox and draft replies. A packaged Agent Skill is also published at github.com/redreplier/agent.
