They have no side effects, do not modify data, execute code, delete information, or commit financial obligations. The tool simply reports the current state of the CSMAR service, making it a low-severity Read operation with minimal blast radius if misused.

{
"version": "1",
"default": "deny",
"tools": {
"csmar_health_check": {}
}
