Implementation Reference

• src/uscardforum/server_tools/auth.py:78-119 (handler)

  Primary MCP tool handler for get_notifications. Defines input schema with Annotated fields and docstring. Delegates execution to DiscourseClient.get_notifications(). The @mcp.tool() decorator handles tool registration.
  @mcp.tool() def get_notifications( since_id: Annotated[ int | None, Field(default=None, description="Only get notifications newer than this ID"), ] = None, only_unread: Annotated[ bool, Field(default=False, description="Only return unread notifications"), ] = False, limit: Annotated[ int | None, Field(default=None, description="Maximum number to return"), ] = None, ) -> list[Notification]: """ Fetch your notifications. REQUIRES AUTHENTICATION. Args: since_id: Only get notifications newer than this ID (optional) only_unread: Only return unread notifications (default: False) limit: Maximum number to return (optional) Must call login() first. Returns a list of Notification objects with: - id: Notification ID - notification_type: Type of notification - read: Whether read - topic_id: Related topic - post_number: Related post - created_at: When created Use to: - Check for new replies to your posts - See mentions and likes - Track topic updates you're watching """ return get_client().get_notifications( since_id=since_id, only_unread=only_unread, limit=limit )
• src/uscardforum/models/auth.py:66-80 (schema)

  Pydantic model defining the structure of each Notification returned by the tool. Used for input/output validation and serialization.
  class Notification(BaseModel): """A user notification.""" id: int = Field(..., description="Notification ID") notification_type: int = Field(..., description="Type of notification") read: bool = Field(False, description="Whether read") created_at: datetime | None = Field(None, description="When created") topic_id: int | None = Field(None, description="Related topic ID") post_number: int | None = Field(None, description="Related post number") slug: str | None = Field(None, description="Topic slug") data: dict[str, Any] = Field(default_factory=dict, description="Extra data") class Config: extra = "ignore"
• src/uscardforum/api/auth.py:181-212 (helper)

  Core implementation in AuthAPI that performs the HTTP GET to /notifications.json, parses responses into Notification models, and applies client-side filtering for since_id, only_unread, and limit parameters.
  def get_notifications( self, since_id: int | None = None, only_unread: bool = False, limit: int | None = None, ) -> list[Notification]: """Fetch notifications (requires auth). Args: since_id: Only notifications after this ID only_unread: Only unread notifications limit: Maximum notifications to return Returns: List of notification objects """ self._require_auth() payload = self._get("/notifications.json") raw_notifications = payload.get("notifications", []) notifications = [Notification(**n) for n in raw_notifications] # Apply filters if since_id is not None: notifications = [n for n in notifications if n.id > since_id] if only_unread: notifications = [n for n in notifications if not n.read] if limit is not None: notifications = notifications[: max(0, int(limit))] return notifications
• src/uscardforum/client.py:490-509 (helper)

  DiscourseClient wrapper method that forwards the get_notifications call to the internal AuthAPI instance.
  def get_notifications( self, since_id: int | None = None, only_unread: bool = False, limit: int | None = None, ) -> list[Notification]: """Fetch notifications (requires auth). Args: since_id: Only notifications after this ID only_unread: Only unread notifications limit: Maximum notifications to return Returns: List of notification objects """ return self._auth.get_notifications( since_id=since_id, only_unread=only_unread, limit=limit )
• src/uscardforum/server.py:65-65 (registration)

  Tool is imported and exposed via __all__ in the main server entrypoint, making it available for the MCP server.
