Implementation Reference

• src/uscardforum/server_tools/users.py:86-118 (handler)

  The MCP tool handler for 'get_user_replies'. Decorated with @mcp.tool(), defines input schema via Annotated Fields, and delegates to the DiscourseClient for execution.
  @mcp.tool() def get_user_replies( username: Annotated[ str, Field(description="The user's handle"), ], offset: Annotated[ int | None, Field(default=None, description="Pagination offset (0, 30, 60, ...)"), ] = None, ) -> list[UserAction]: """ Fetch replies/posts made by a user in other topics. Args: username: The user's handle offset: Pagination offset (0, 30, 60, ...) Returns a list of UserAction objects with: - topic_id: Which topic they replied to - post_number: Their post number in that topic - title: Topic title - excerpt: Preview of their reply - created_at: When they replied Use this to: - See a user's contributions across topics - Find their data points and experiences - Evaluate the quality of their participation Paginate with offset in increments of 30. """ return get_client().get_user_replies(username, offset=offset)
• src/uscardforum/server_tools/__init__.py:37-47 (registration)

  Registration via import into server_tools __init__.py, exposing get_user_replies for use in the MCP server.
  from .users import ( get_user_summary, get_user_topics, get_user_replies, get_user_actions, get_user_badges, get_user_following, get_user_followers, get_user_reactions, list_users_with_badge, )

  Top-level re-export of all tools including get_user_replies in the main server entrypoint.

• src/uscardforum/api/users.py:112-127 (helper)

  Client-side API method implementing get_user_replies by calling get_user_actions with filter=5 (replies). Called by the DiscourseClient.
