- src/mcp_reddit/reddit_fetcher.py:68-102 (handler)The main asynchronous handler function for the 'fetch_reddit_post_content' tool. It fetches the Reddit post using redditwarp Client, extracts post details, retrieves top comments up to specified limit and depth, formats them using helper functions, and returns a formatted string. Registered via @mcp.tool() decorator.async def fetch_reddit_post_content(post_id: str, comment_limit: int = 20, comment_depth: int = 3) -> str: """ Fetch detailed content of a specific post Args: post_id: Reddit post ID comment_limit: Number of top level comments to fetch comment_depth: Maximum depth of comment tree to traverse Returns: Human readable string containing post content and comments tree """ try: submission = await client.p.submission.fetch(post_id) content = ( f"Title: {submission.title}\n" f"Score: {submission.score}\n" f"Author: {submission.author_display_name or '[deleted]'}\n" f"Type: {_get_post_type(submission)}\n" f"Content: {_get_content(submission)}\n" ) comments = await client.p.comment_tree.fetch(post_id, sort='top', limit=comment_limit, depth=comment_depth) if comments.children: content += "\nComments:\n" for comment in comments.children: content += "\n" + _format_comment_tree(comment) else: content += "\nNo comments found." return content except Exception as e: return f"An error occurred: {str(e)}"
