WHAT IT DOES

What self_heal_unit does on Nitrostack

AI agents invoke self_heal_unit to trigger actions in Nitrostack. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why self_heal_unit is rated High

Rerouting operational logic triggers external system changes with potentially broad blast radius.

RECOMMENDED RULE

The rule that runs self_heal_unit safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nitrostack, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For self_heal_unit, this is the rule to start with:

self_heal_unit Rate-limited

self_heal_unit stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on self_heal_unit? +

Register the Nitrostack MCP server in PolicyLayer and add a rule for self_heal_unit: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Nitrostack. Nothing to install.

What risk level is self_heal_unit? +

Can I rate-limit self_heal_unit? +

Yes. Add a rate_limit block to the self_heal_unit rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block self_heal_unit completely? +
