Implementation Reference
- src/mcp_server_reddit/server.py:145-150 (handler)The core handler function that fetches hot posts from a subreddit using the redditwarp client and builds a list of Post objects using the _build_post helper.def get_subreddit_hot_posts(self, subreddit_name: str, limit: int = 10) -> list[Post]: """Get hot posts from a specific subreddit""" posts = [] for subm in self.client.p.subreddit.pull.hot(subreddit_name, limit): posts.append(self._build_post(subm)) return posts
- The input schema definition for the tool, specifying subreddit_name as required and limit as optional with bounds.inputSchema={ "type": "object", "properties": { "subreddit_name": { "type": "string", "description": "Name of the subreddit (e.g. 'Python', 'news')", }, "limit": { "type": "integer", "description": "Number of posts to return (default: 10)", "default": 10, "minimum": 1, "maximum": 100 } }, "required": ["subreddit_name"] }
- src/mcp_server_reddit/server.py:232-252 (registration)Registration of the tool in the list_tools() handler, defining name, description, and input schema.Tool( name=RedditTools.GET_SUBREDDIT_HOT_POSTS.value, description="Get hot posts from a specific subreddit", inputSchema={ "type": "object", "properties": { "subreddit_name": { "type": "string", "description": "Name of the subreddit (e.g. 'Python', 'news')", }, "limit": { "type": "integer", "description": "Number of posts to return (default: 10)", "default": 10, "minimum": 1, "maximum": 100 } }, "required": ["subreddit_name"] } ),
- src/mcp_server_reddit/server.py:390-395 (registration)Dispatch logic in the call_tool() handler that extracts arguments and invokes the get_subreddit_hot_posts method.case RedditTools.GET_SUBREDDIT_HOT_POSTS.value: subreddit_name = arguments.get("subreddit_name") if not subreddit_name: raise ValueError("Missing required argument: subreddit_name") limit = arguments.get("limit", 10) result = reddit_server.get_subreddit_hot_posts(subreddit_name, limit)
- Key helper function used by the handler to construct Post model instances from redditwarp submission objects.def _build_post(self, submission) -> Post: """Helper method to build Post object from submission""" return Post( id=submission.id36, title=submission.title, author=submission.author_display_name or '[deleted]', score=submission.score, subreddit=submission.subreddit.name, url=submission.permalink, created_at=submission.created_at.astimezone().isoformat(), comment_count=submission.comment_count, post_type=self._get_post_type(submission), content=self._get_post_content(submission) )
