  Chatbot v0.3.0

  What is new in plain terms

  • A completely new worker module has been added to handle MCP tool execution, running as a separate process that communicates with the server via WebSocket.
  • Workers now have full authentication with JWT-based registration and login, including service tokens and challenge-response security.
  • MCP tool execution has been moved from client to server worker — the client no longer executes MCP tools directly.
  • A new worker management UI lets you view, update, and delete registered workers from settings.
  • The settings screen has been redesigned with a collapsible sidebar and organized pages.
  • Workers can now be deployed via Docker with auto-start support after initial setup.

  User-facing improvements

  New worker module for MCP tool execution

  • Added a new worker/ module that runs as a standalone process handling all MCP tool calls.
  • Workers connect to the server via WebSocket for bidirectional communication.
  • Each worker has a public UID for external identification.
  • Workers support layered configuration (defaults → secrets → runtime).

  Worker authentication system

  • Workers can now register with the server and receive authentication credentials.
  • JWT-based authentication with separate audiences for users and workers.
  • Service token authentication with challenge-response security.
  • Workers must complete a session handshake before becoming operational.

  Worker management UI

  • Added a worker management section in settings to view all registered workers.
  • Workers can be updated (display name, configuration) and deleted from the UI.
  • Added a worker selection dropdown in the MCP server dialog to choose which worker handles tool execution.
  • Display name resolution is now delegated to the worker setup flow.

  Settings screen redesign

  • Complete overhaul of the settings UI with a collapsible sidebar navigation.
  • Settings are organized into pages for better structure.
  • Added generation-based content control in the topbar for better streaming behavior.

  MCP runtime improvements

  • MCP runtime status is now refreshed automatically after server operations.
  • Client runtime has auto-stop functionality when not in use.
  • Worker runtime properly closes and cleans up MCP resources on shutdown.

  Self-hosting and deployment improvements

  • Added Docker support for the worker module.
  • Workers can be configured to auto-start after initial setup.
  • Added server URL resolution logic for worker setup.
  • Worker configuration is now secured with layered approach (secrets separated from defaults).

  Security and reliability

  • JWT authentication now uses separate audiences for users and workers.
  • Worker configuration is restructured and secured with proper separation of sensitive data.
  • Session handshake completion is now enforced before workers can process requests.
  • Local MCP server API resources have been removed (client-side execution deprecated).

  Build and packaging

  • Worker module has its own Gradle build configuration.
  • Build and application defaults are properly configured for the worker.
  • All tests continue to pass across the application.

  Docs and project housekeeping

  • Expanded onboarding and project documentation.
  • Reorganized documentation files for better structure.
  • Cleaned up local IDE configuration files.
