Reddit is a social platform with millions of users across 100k+ communities. The Reddit MCP server lets you search subreddits, fetch posts, manage comments, and publish content using natural language.
Reddit MCP nodes require you to bring your own Reddit app credentials. If you only need read-only access, use the Reddit Scraper node instead, which works without credentials.If you only need to fetch posts, comments, or search subreddits, use the Reddit Scraper node instead. It works out of the box without any custom credentials and is easier to set up.

​
What Can It Do?

  • Search subreddits and discover communities
  • Fetch posts with full details and comments
  • Create and edit posts in any subreddit
  • Manage comments on your posts

​
Where to Use It

Add Reddit as a tool to any agent. The agent can then interact with Reddit conversationally, choosing the right actions based on context. To add an MCP tool to your agent:
  1. Open your agent’s configuration
  2. Click Add tools → Connect an app with MCP
  3. Search for the integration and select it
  4. Authenticate with your Reddit app credentials
You can control which tools your agent has access to. After adding an integration, click on it to enable or disable specific tools based on what your agent needs.

​
In Workflows (Via Agent Node)

For automated pipelines, use an Agent Node with Reddit tools. This gives you the flexibility of an agent within a deterministic workflow.

​
As a Custom MCP Node

You can also create a standalone MCP node for a specific action. This generates a reusable node that performs one task, useful when you need the same operation repeatedly in workflows.
To create a custom MCP node:
  1. Go to your node library and search for the integration
  2. Click Create a node with AI
  3. Describe the specific action you want (e.g., “Get top posts from r/programming”)
  4. Test the node and save it for reuse
Custom MCP nodes are single-purpose by design. For tasks that require multiple steps or dynamic decision-making, use an agent instead.

​
Setting Up Credentials

Reddit MCP requires your own Reddit app credentials. See the Reddit app preferences to create an app, or request enterprise API access for high-volume use cases.

Troubleshooting

IssueSolution
Agent not finding the right dataUse specific subreddit names or post URLs
Action not completingCheck that you’ve configured Reddit app credentials
Unexpected resultsThe agent may chain multiple tools (e.g., searching first, then getting details). Review the agent’s reasoning to understand its approach.
Tool not availableVerify the tool is enabled in your agent’s MCP configuration
Authentication errorsVerify your Reddit app credentials in Gumloop Credentials
Agents are smart enough to chain multiple API calls together. For example, asking “Get comments from the top post in r/programming” will fetch posts first, then get comments. If results seem off, check the agent’s step-by-step reasoning.
