This release introduces Profiles v2, enabling users to manage multiple MCP server configurations and switch between them dynamically, plus enhanced security isolation options.

New Features

Profiles v2 (Teams edition)

  • Per-profile tool indexes: Each profile now maintains its own Bleve search index for faster, isolated tool discovery
  • Profile switching via MCP tool: Agents can now switch profiles programmatically using the new set_profile MCP tool
  • Profile management REST API: New /api/v1/profiles endpoint for profile CRUD operations
  • Profile pinning per agent token: Pin specific agents to profiles with server-side enforcement to prevent unauthorized profile switching
  • Real-time profile updates: Server-Sent Events (SSE) broadcast active profile changes to connected clients
  • Web UI profile switcher: New header control for selecting active profiles in the dashboard

Profiles v2 (Personal edition)

  • System tray profile switcher: Quick profile switching directly from the macOS/Windows system tray menu

Security & Isolation

  • Configurable isolation modes: New isolation.mode enum setting allows choosing between Docker, Landlock, or no sandboxing
  • Landlock sandbox (experimental): Proof-of-concept Linux kernel-based sandboxing for MCP servers without Docker dependency
  • Per-server initialize timeout: Configure custom MCP protocol initialization timeouts for individual servers to handle slow-starting tools

Bug Fixes

  • Fixed index pagination when rebuilding or clearing per-profile indexes that exceed search page limits

Improvements

  • Mode-aware server selector automatically filters available servers based on configured isolation mode
  • Enhanced observability with proper user_id and profile label values in metrics (Teams edition)

v0.43.1

This release focuses on bug fixes and reliability improvements, particularly around configuration handling, text encoding, and server imports.

Bug Fixes

  • Configuration management: Fixed an issue where not all server configuration fields were properly copied during config operations, which could lead to incomplete server settings
  • Text handling: Resolved UTF-8 encoding errors in direct-mode by ensuring text truncation occurs at valid character boundaries instead of mid-character
  • Server imports: Fixed conflict resolution when importing servers with duplicate names, ensuring the conflict-rename mapping works correctly with both original and sanitized server names
  • Release process: Improved reliability of the code-signing retry mechanism with corrected artifact patterns

New Features

  • Audit logging (Teams edition): Added per-user audit records for credential brokering operations, providing detailed tracking of credential access and usage for compliance and security monitoring (MCP Spec 074 T10)

v0.42.0

This release introduces enhanced control over tool approval workflows with per-server auto-approval settings and new CLI commands for managing quarantined tools.

New Features

  • Per-Server Auto-Approve Toggle: Configure auto-approval of tool changes independently for each MCP server through the UI (Personal & Teams)
  • Trust Baseline & Rug-Pull Detection: New trust-baseline approval mode automatically flags suspicious tool changes that may indicate malicious updates (Personal & Teams)
  • CLI Tool Management: Added tools approve and tools reject commands for managing pending quarantined tools from the command line (Personal & Teams)
  • Batch Tool Approval: Approve or reject multiple pending tools at once from the global Tools page (Personal & Teams)
  • Auto-Approve Configuration: New auto_approve_tool_changes flag replaces the deprecated skip_quarantine setting, providing clearer control over tool approval behavior (Personal & Teams)

Improvements

  • Tool approval settings are now exposed and persisted through the REST API for programmatic configuration (Teams)
  • Pending tools are now prominently displayed in the ServerDetail approval banner for better visibility (Personal & Teams)

Breaking Changes

  • The skip_quarantine configuration flag is deprecated in favor of auto_approve_tool_changes. Existing configurations will be automatically migrated, but you should update your config files to use the new flag name.

v0.41.2

This release fixes a Docker credential helper issue affecting upstream MCP server connections.

Bug Fixes

  • Docker credential helpers: Fixed PATH resolution for Docker credential helpers when running in bundled environments. The Docker bundle directory is now correctly prepended to the child process PATH, ensuring credential helpers can be properly located and executed (#716)

This fix applies to both Personal and Teams editions when using Docker-based MCP servers that require authentication.

v0.41.1

This release focuses on security and reliability improvements for upstream Docker-based MCP server execution.

Bug Fixes

  • Fixed Docker binary resolution for user-supplied configurations - Resolved an issue where the direct-exec mode failed to properly resolve the Docker binary path when users provided custom docker run commands for upstream MCP servers. This ensures more reliable container execution across different system configurations.

  • Enhanced security logging - Upstream secrets (such as API keys and authentication tokens) are now properly redacted from Docker spawn argument debug logs. This prevents sensitive configuration data from being exposed in log files when troubleshooting Docker-based MCP server deployments.

Both fixes apply to Personal and Teams editions when using Docker-based upstream MCP servers.

v0.40.0

This release focuses on Docker isolation improvements, environment handling for macOS GUI users, and security scan UI reliability fixes.

New Features

  • Environment Variable Forwarding (Teams): New opt-in configuration to forward proxy environment variables to upstream MCP servers for controlled network access (MCP-2769)
  • macOS Login Shell Support (Personal): GUI app now hydrates login-shell environment once at startup, ensuring consistent environment variables when launched via launchd (MCP-2751)
  • Enhanced Telemetry: Added tracking for Docker isolation flag, CLI source identification, and Docker failure codes (schema v5)

Bug Fixes

  • Security Scan UI (Teams): Fixed issue where security scan interface remained stuck on "Scanning…" despite backend job completion (MCP-2740)
  • Scan Cancellation Handling (Teams): Cancelled security scans are now properly treated as non-success states in finalization logic (MCP-2755)
  • Docker Binary Resolution: Improved Docker binary resolution for isolated spawn processes, preventing execution failures in containerized environments (MCP-2753)
  • Docker Path Caching: Fixed stat-probe logic to correctly override negative cache entries in Docker path resolution, improving reliability when Docker becomes available after initial checks
