• src/mcp_server_reddit/server.py:419-425 (handler)

  Dispatch handler in the MCP call_tool() function that handles the get_post_content tool call by parsing arguments and invoking the RedditServer.get_post_content method.

  case RedditTools.GET_POST_CONTENT.value:
      post_id = arguments.get("post_id")
      if not post_id:
          raise ValueError("Missing required argument: post_id")
      comment_limit = arguments.get("comment_limit", 10)
      comment_depth = arguments.get("comment_depth", 3)
      result = reddit_server.get_post_content(post_id, comment_limit, comment_depth)

• src/mcp_server_reddit/server.py:84-92 (helper)

  Helper function used by _build_post to extract the content string from a Reddit submission based on its type (link, text, gallery). Called indirectly via the main handler.

  def _get_post_content(self, submission) -> str | None:
      """Helper method to extract post content based on type"""
      if isinstance(submission, redditwarp.models.submission_SYNC.LinkPost):
          return submission.permalink
      elif isinstance(submission, redditwarp.models.submission_SYNC.TextPost):
          return submission.body
      elif isinstance(submission, redditwarp.models.submission_SYNC.GalleryPost):
          return str(submission.gallery_link)
      return None
