ha-mcp

The server's security is largely dependent on the underlying Home Assistant instance it connects to and the validity of the provided long-lived access token. The application logic generally delegates complex operations (like template evaluation) to Home Assistant's internal APIs, relying on HA's inherent sandboxing. File system interactions, such as those related to the 'ha_mcp_tools' custom component, include explicit path validation against allowed directories, demonstrating a conscious effort to limit potential access. The 'ha_install_mcp_tools' tool, which handles HACS component installation, is disabled by default behind a feature flag and targets a specific hardcoded repository, preventing arbitrary code injection through user input. Proper management of Home Assistant itself, including strong API token security, is crucial.
