Implementation Reference

• src/uscardforum/server_tools/auth.py:64-76 (handler)

  MCP tool handler for get_current_session. Registers the tool and delegates to the shared client instance.
  @mcp.tool() def get_current_session() -> Session: """ Get information about the current session. Returns a Session object with: - is_authenticated: Whether logged in - current_user: CurrentUser object with user info (if authenticated) Use to verify authentication status. """ return get_client().get_current_session()
• src/uscardforum/models/auth.py:46-64 (schema)

  Pydantic model for Session return type, including from_api_response factory method.
  class Session(BaseModel): """Current session information.""" current_user: CurrentUser | None = Field(None, description="Logged-in user") is_authenticated: bool = Field(False, description="Whether authenticated") class Config: extra = "ignore" @classmethod def from_api_response(cls, data: dict[str, Any]) -> "Session": """Parse from raw API response.""" user_data = data.get("current_user") or data.get("user") current_user = CurrentUser(**user_data) if user_data else None return cls( current_user=current_user, is_authenticated=current_user is not None, )
• src/uscardforum/api/auth.py:97-111 (helper)

  Core API implementation that fetches session from /session/current.json endpoint and handles unauthenticated case.
  def get_current_session(self) -> Session: """Get current session info. Returns: Session data including user info (unauthenticated if no session) """ try: payload = self._get("/session/current.json") return Session.from_api_response(payload) except requests.exceptions.HTTPError as e: # 404 means no session - return unauthenticated session if e.response is not None and e.response.status_code == 404: return Session(is_authenticated=False, current_user=None) raise
• src/uscardforum/client.py:482-488 (helper)

  Client wrapper that delegates to AuthAPI.get_current_session()
  def get_current_session(self) -> Session: """Get current session info. Returns: Session data including user info """ return self._auth.get_current_session()
• src/uscardforum/server_core.py:136-168 (helper)

  Shared singleton client factory used by all tools, with optional auto-login.
