Implementation Reference

• src/uscardforum/server_tools/auth.py:121-173 (handler)

  MCP tool handler for bookmark_post. Defines input schema with Pydantic Field descriptions and proxies execution to the underlying client.bookmark_post method. Requires prior authentication via login tool.

• src/uscardforum/server_tools/__init__.py:52-58 (registration)

  Re-exports the bookmark_post tool from the auth submodule, making it available at the server_tools package level for easy import in the main server.
  from .auth import ( login, get_current_session, get_notifications, bookmark_post, subscribe_topic, )
• src/uscardforum/server.py:15-45 (registration)

  Imports all MCP tools including bookmark_post from server_tools package. This exposure in the server entrypoint ensures the @mcp.tool decorated functions are registered when the server runs.
  from uscardforum.server_tools import ( analyze_user, bookmark_post, compare_cards, find_data_points, get_all_topic_posts, get_categories, get_current_session, get_hot_topics, get_new_topics, get_notifications, get_top_topics, get_topic_info, get_topic_posts, get_user_actions, get_user_badges, get_user_followers, get_user_following, get_user_reactions, get_user_replies, get_user_summary, get_user_topics, list_users_with_badge, login, research_topic, resource_categories, resource_hot_topics, resource_new_topics, search_forum, subscribe_topic, )
• src/uscardforum/api/auth.py:251-302 (helper)

  Underlying API helper method in AuthAPI that performs the actual HTTP POST request to /bookmarks.json to create the bookmark, handling CSRF, form data, and response parsing. Called indirectly by the MCP handler via client proxy.
