<!-- CURSOR_SUMMARY --> > [!NOTE] > **Medium Risk** > Touches authentication/login flow, credentials-file permissions, and subprocess lifecycle behavior across platforms; while mostly defensive, regressions could impact login or process management on Windows/macOS runners. > > **Overview** > Improves Windows/cross-platform reliability across the CLI and MCP server: OAuth login now binds the callback server to `127.0.0.1`, avoids slow loopback reverse-DNS, adds a configurable callback timeout (`--timeout` + env default), and opens URLs via a Windows-friendly `_open_browser` to avoid flashing console windows. > > Centralizes CLI output via a shared `console` that forces UTF-8 on Windows, standardizes UTF-8 file reads/writes throughout, tightens credentials-file permissions on Windows using `icacls`, and adds shared Windows subprocess helpers for **no-window** process creation and graceful termination (used by `deploy`, MCP reload, and usage-tracking worker). > > Updates client configuration UX/robustness (Windows AppData resolution via `platformdirs`, Cursor config path fallbacks + compatibility writes, overwrite warnings, absolute `uv` path for GUI clients, safer path display) and improves `deploy` child-process handling to avoid pipe-buffer deadlocks while giving better debug-aware error messages. > > Expands CI to run tests on Linux/Windows/macOS, adds a no-auth CLI integration workflow, disables usage tracking in toolkits CI, and adds extensive regression tests for Windows signals, subprocess cleanup, UTF-8, and config-path edge cases; bumps `arcade-core` to `4.4.2` and `arcade-mcp-server` to `1.17.2` (with updated dependency pin). > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 0fabd8ca1cd647039ba6ddbdf3f7809c330bab9e.

Analytics & Privacy
Arcade MCP Server collects anonymous usage data to help us improve the service and debug issues. We track "MCP server start" events to understand server usage patterns and reliability.
What We Track
When the server starts, we collect the following information:
- Server configuration: transport type (
httporstdio), host, port - Server metadata: tool count, server version
- Runtime environment: Python version, OS type and release
- Timing: device timestamp
- Errors: error messages (if startup fails)
Privacy
- For anonymous users: Events are tracked with an anonymous ID and no user profile is created
- For authenticated users: Events are linked to your account to help us provide better support
- No sensitive data (credentials, tool inputs/outputs, or personal information) is ever collected
Opt Out
To disable usage tracking, set the environment variable ARCADE_USAGE_TRACKING to 0.
