Resolves https://linear.app/arcadedev/issue/TOO-788/mypy-failures-are-silently-dropped-during-arcade-mcp-ci <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > Low risk: primarily CI/Makefile behavior and type-annotation tweaks; functional logic is unchanged aside from stricter failure propagation in `make check`. > > **Overview** > **Stops CI from silently ignoring mypy failures.** The `make check` target now runs `mypy` across `libs/arcade*/` and exits non-zero if any package fails, reporting the failed libs. > > Separately tightens typing to satisfy `mypy` (removing `type: ignore` on OAuth helpers, adding `cast()`/`Any` annotations for JSON response shapes and subprocess kwargs, and handling non-`str` `server_address` hosts), and bumps patch versions for `arcade-mcp` and `arcade-mcp-server`. > > <sup>Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit e79575b13a2d03adf3548104a0064c643f1e21b1.

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.
