Implementation Reference
- src/mcp_server_reddit/server.py:166-171 (handler)Core implementation of the get_subreddit_rising_posts tool. Fetches rising posts from the specified subreddit using redditwarp SYNC client and maps them to Post model instances.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
- Pydantic model defining the structure of Post objects returned by the tool.class Post(BaseModel): id: str title: str author: str score: int subreddit: str url: str created_at: str comment_count: int post_type: PostType content: str | None
- src/mcp_server_reddit/server.py:301-321 (registration)MCP tool registration including name, description, and input schema validation.Tool( name=RedditTools.GET_SUBREDDIT_RISING_POSTS.value, description="Get rising 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:412-417 (handler)Dispatch handler in call_tool() that validates arguments and invokes the RedditServer method.case RedditTools.GET_SUBREDDIT_RISING_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_rising_posts(subreddit_name, limit)
- Helper function used by the handler to convert redditwarp submission objects to Post models.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) )
