Tools & Capabilities Breakdown

Reddit MCP Buddy Tools (5)

browse_subreddit

Fetch posts from a subreddit sorted by your choice (hot/new/top/rising/controversial). Returns a post list with content, metadata, and a data_source field. With Reddit credentials (data_source "api") posts include score, num_comments, and upvote_ratio; without credentials, results come from Reddit's public RSS feed (data_source "rss") and those fields plus nsfw are null — see the response note and do not infer popularity from them.

search_reddit

Search for posts across Reddit or specific subreddits. Returns matching posts with content and metadata.

get_post_details

Fetch a Reddit post with its comments. Requires EITHER url OR post_id. IMPORTANT: When using post_id alone, an extra API call is made to fetch the subreddit first (2 calls total). For better efficiency, always provide the subreddit parameter when known (1 call total).

user_analysis

Analyze a Reddit user's posting history, karma, and activity patterns. Returns posts, comments, and statistics.
