This one needs environment variables set before it will start: MS_CLIENT_ID (Microsoft Entra (Azure AD) application client ID), MS_CONFIG_DIR (Path to the per-user Microsoft config directory (credentials/, accounts.json)), MS_ACCOUNT_EMAIL (Account email when running in multi-account per-instance mode (falls back to the first account in accounts.json)), MS_MCP_PACKAGE_ID (Logical package ID surfaced in error responses), MICROSOFT_REQUEST_TIMEOUT_MS (Override the upstream Microsoft Graph request timeout in milliseconds (max 300000 = 5 min)). The author declared them in the registry entry; get the values from the project itself.
