Implementation Reference

• src/uscardforum/server_tools/topics.py:201-257 (handler)

  Primary MCP tool handler for get_all_topic_posts. Decorated with @mcp.tool(), defines input/output schema using Annotated and Field, implements logic by delegating to DiscourseClient.get_all_topic_posts().
  @mcp.tool() def get_all_topic_posts( topic_id: Annotated[ int, Field(description="The numeric topic ID"), ], include_raw: Annotated[ bool, Field(default=False, description="Include markdown source (default: False)"), ] = False, start_post_number: Annotated[ int, Field(default=1, description="First post to fetch (default: 1)"), ] = 1, end_post_number: Annotated[ int | None, Field(default=None, description="Last post to fetch (optional, fetches to end if not set)"), ] = None, max_posts: Annotated[ int | None, Field(default=None, description="Maximum number of posts to return (optional safety limit)"), ] = None, ) -> list[Post]: """ Fetch all posts from a topic with automatic pagination. Args: topic_id: The numeric topic ID include_raw: Include markdown source (default: False) start_post_number: First post to fetch (default: 1) end_post_number: Last post to fetch (optional, fetches to end if not set) max_posts: Maximum number of posts to return (optional safety limit) This automatically handles pagination to fetch multiple batches. IMPORTANT: For topics with many posts (>100), use max_posts to limit the response size. You can always fetch more with start_post_number. Use cases: - Fetch entire small topic: get_all_topic_posts(topic_id=123) - Fetch first 50 posts: get_all_topic_posts(topic_id=123, max_posts=50) - Fetch posts 51-100: get_all_topic_posts(topic_id=123, start_post_number=51, max_posts=50) - Fetch specific range: get_all_topic_posts(topic_id=123, start=10, end=30) Returns the same Post structure as get_topic_posts but for all matching posts. Pro tip: Use get_topic_info first to check post_count before deciding whether to fetch all or paginate manually. """ return get_client().get_all_topic_posts( topic_id, include_raw=include_raw, start_post_number=start_post_number, end_post_number=end_post_number, max_posts=max_posts, )
