1. Resolves [TOO-363](https://linear.app/arcadedev/issue/TOO-363/arcade-deploy-fails-when-additional-deps-are-added-to-the-server). 2. Resolves [TOO-364](https://linear.app/arcadedev/issue/TOO-364/arcade-cores-tool-skip-logic-is-missing-case-for-direct-execution). 3. Resolves [TOO-358](https://linear.app/arcadedev/issue/TOO-358/missing-evals-error-message-shows-wrong-command). 4. Resolves [TOO-365](https://linear.app/arcadedev/issue/TOO-365/arcade-evals-unit-tests-are-hanging). <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Medium Risk** > Medium risk because it changes how `arcade deploy` spawns the server process and adjusts toolkit discovery skip logic, which can affect deployments and tool discovery; however, the changes are small and covered by new unit/integration tests. > > **Overview** > `arcade deploy` now starts the validation server using the project’s `.venv` interpreter (via `find_python_interpreter`) instead of the CLI’s own `sys.executable`, preventing missing dependency failures when the CLI is installed in an isolated env. > > `arcade-core`’s `Toolkit.tools_from_directory` skip logic is hardened to also skip the currently executing entrypoint by module name (`__main__.__spec__.name`) when file paths don’t match (e.g., bundled execution). CLI error printing now escapes plain messages to avoid rich markup issues, and `arcade-evals` lock acquisition accepts an optional timeout default. > > Adds unit tests for the new toolkit skip behavior and an integration test that boots the MCP server via direct Python invocation to mirror deployment behavior, and bumps `arcade-core`, `arcade-mcp-server`, and root dependency versions accordingly. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit e7785634c231c059f2e0bd1bc73a56bd7470a494.

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.
