MCP
Stay on top of the conversations that matter, discover emerging trends, and even publish directly to Reddit - all without touching the Reddit API. With the Reddit integration you can search subreddits, pull rich post data, manage comments, and create or edit posts using nothing more than natural language prompts.
A more efficient approach is to split the work into smaller nodes:
Tap into the global Reddit community of over 430 million monthly users and 100k+ active subreddits - perfect for monitoring niches, gathering insights, and engaging in real time.
What is Reddit MCP?
When you create a Reddit MCP node, Gumloop automatically builds a custom node that understands Reddit’s API. Just describe what you want in plain English and the node handles authentication, endpoints, and formatting behind the scenes. You can then reuse that node anywhere in your workflows.What Can It Do for You?
- Pull the hottest, newest, or top posts from any subreddit in seconds
- Drill into a specific post to grab full text, score, author, and more
- Publish, edit, or delete posts and comments without leaving Gumloop
- Search across subreddits, posts, or user profiles to surface exactly what you need

How to Use
1
Create Your Reddit MCP Node
Go to your node library, search for Reddit, and click “Create a node with AI”
2
Add Your Prompt
Drag the Reddit MCP node to your canvas and add your prompt in the text box.
3
Test Your Node
Run the node to see the results. If it works as expected, you’re all set! If you run into issues, check the troubleshooting tips below.
4
Save and Reuse
Once your Reddit MCP node is working, save it to your library. You can now use this customized node in any workflow.
Example Prompts
Here are some prompts that work well with Reddit MCP:Start with a single, focused action and specify the exact fields you want back - this keeps runs fast and outputs tidy.
Troubleshooting
If your Reddit MCP node isn’t working as expected, try these best practices:Keep Prompts Simple and Specific
- Good: “Fetch the top 3 hot posts from r/startups and return title and score”
- Less efficient: “Fetch the top 10 posts from r/startups, summarize each one, then email the summaries to me”
For best results, keep Reddit MCP focused on one Reddit action, then pass the output to other nodes for summarization or emailing.
Match What Reddit Can Do
- Good: “Delete Reddit post with
Post URL” - Less efficient: “Delete the post and update a Google Sheet with the result”
Reddit MCP excels at Reddit actions. To update spreadsheets, follow up with Google Sheets Updater in your workflow.
Break Complex Tasks Into Steps
Trying to do too much in a single prompt might cause timeouts or unexpected errors:1
Step 1: Find Subreddits
Search subreddits about AI and return subreddit_name and ID
2
Step 2: Get Posts
For each subreddit ID, fetch the top 5 posts and return post_id, title, and selftext
3
Step 3: Summarize Posts
Summarize each post using Ask AI and return a concise summary
4
Step 4: Publish Summaries
Send each summary via Tweet node with the post link
Connect these nodes sequentially in your workflow. The subreddit IDs from Step 1 feed into Step 2, post details from Step 2 feed into Step 3, and summaries from Step 3 go to Step 4.
Focus on Data Retrieval
Reddit MCP is great at getting information from Reddit. For analysis or content creation, pair it with other nodes. Example:- Good prompt: “Get Reddit post details for
Post URLand return title, body_text, and score” - Less efficient: “Get post details and write a 500-word blog post about it”
Use Ask AI or another writing node for content creation. Keep Reddit MCP focused on retrieving or managing Reddit data.
