<!-- CURSOR_SUMMARY --> > [!NOTE] > Adds --workers to HTTP mode with validation, refactors server startup/discovery for multi-process uvicorn, and removes all Docker-related files/configs. > > - **MCP Server (HTTP mode)** > - Add `--workers` arg to run multiple uvicorn workers; block `workers > 1` with `stdio`, and `reload` with multiple workers. > - Refactor startup: move tool discovery/config into `create_arcade_mcp_factory()` driven by env vars; use `uvicorn.run(..., workers=...)` for multi-worker/reload; retain `serve_with_force_quit()` only for single-worker. > - Adjust CLI to only discover tools in `stdio` path; HTTP path now delegates discovery to the factory. > - **MCPApp** > - Minor run path cleanup; continue using `serve_with_force_quit()` for single-worker HTTP. > - **Ops/Packaging** > - Remove `docker/` directory and all Dockerfiles, compose/configs, and docs. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit c5700ac8855173c1e82c6f7e41b30ca173aaec14.

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.
