Leave r/memes out from now on.

filters updated
Done. r/memes is out for the whole workspace.
A monitor, not a live search
What your agent gets from a Reddit MCP server
The usual Reddit MCP server is a thin layer over Reddit's API: an app you register, credentials in a local config, a process on your laptop, and a live search every time the model asks.
Rumoro does the searching ahead of time. It checks every subreddit for your keywords every 30 minutes, stores the matches and scores each one against what your company does. So when you ask, the answers are already waiting: this week's threads, posts from people ready to buy, the subreddits where a rival keeps turning up.
X, Hacker News, LinkedIn and the other sources sit on the same server, so a single question spans all of them.

Next, give it something to watch on Reddit
Create a keyword limited to Reddit in the dashboard, or ask your agent to. It begins with recent posts from the past month and adds each new match after that.

Then just ask
What you can ask about Reddit
Ask in plain words; your agent chooses the tool. All of these work on day one.
“Has anyone on Reddit asked for a recommendation in our category this month?”
rumoro · search_mentions“Who on Reddit talks about our competitor the most?”
rumoro · list_people“Ping #sales in Slack whenever a Reddit post shows buying intent.”
rumoro · create_alert“Stop collecting from r/memes and r/cryptocurrency.”
rumoro · update_filters“What do people on Reddit dislike about our pricing? Write a reply I could post.”

Reddit MCP questions
Questions about the Reddit MCP server
What is a Reddit MCP server?
It's a server that speaks the Model Context Protocol, so AI clients like Claude, Cursor and Codex can call it as tools for Reddit. Most are open-source wrappers around Reddit's API that you run yourself with your own Reddit app. Rumoro's is hosted and works from a feed it keeps: your keywords, watched on Reddit and other sources, with every post scored.
Do I need Reddit API keys?
No. Rumoro does the Reddit side itself, so you skip registering an app, handling credentials and waiting on Reddit's approval. Sign in to Rumoro in the browser once, or give a headless machine a Rumoro API key.
How do I add the Reddit MCP server to Claude?
Claude Code: run claude mcp add --transport http rumoro https://mcp.rumoro.dev/mcp, open /mcp in a session, choose rumoro and Authenticate. Claude Desktop or claude.ai: Customize › Connectors, + Add › Add custom connector, paste https://mcp.rumoro.dev/mcp, then sign in. Finally create a keyword limited to Reddit, or ask Claude to create it.
Can it search any Reddit post, or only my keywords?
Only what your keywords have matched. Rumoro is built to watch, not to search on demand: it checks every subreddit for each keyword every 30 minutes, and a fresh keyword comes with recent posts from the past month. To look up arbitrary terms on the spot, an open-source server with your own Reddit app is the right tool.
How much does it cost?
Using the MCP server adds nothing to your bill. Rumoro charges for what it tracks: $5 for each keyword a month and $0.008 for each matched post, taken from credit you top up, with no subscription. New workspaces get $5.80 to start.
