Implementation Reference

• src/uscardforum/server_tools/users.py:50-83 (handler)

  The primary MCP tool handler for 'get_user_topics'. Decorated with @mcp.tool(), defines input schema via Annotated Fields, and delegates to DiscourseClient.get_user_topics() for execution.

  @mcp.tool()
  def get_user_topics(
      username: Annotated[
          str,
          Field(description="The user's handle"),
      ],
      page: Annotated[
          int | None,
          Field(default=None, description="Page number for pagination"),
      ] = None,
  ) -> list[dict[str, Any]]:
