Implementation Reference
- src/mcp_server_reddit/server.py:166-171 (handler)The main handler function that fetches rising posts from the specified subreddit using the redditwarp SYNC client and constructs Post objects using the _build_post helper.
def get_subreddit_rising_posts(self, subreddit_name: str, limit: int = 10) -> list[Post]: """Get rising posts from a specific subreddit""" posts = [] for subm in self.client.p.subreddit.pull.rising(subreddit_name, limit): posts.append(self._build_post(subm)) return posts - Input schema definition for the tool, specifying required 'subreddit_name' parameter and optional 'limit'.
