resolve_alert · KVMFleet MCP Server MCP: Risk & Policy

WHAT IT DOES

What resolve_alert does on KVMFleet MCP Server

AI agents use resolve_alert to create or update resources in KVMFleet MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your KVMFleet MCP Server environment.

WHY IT NEEDS A POLICY

Why resolve_alert needs a policy

The tool modifies alert state by marking a condition as handled. This is a reversible write operation (alerts can typically be re-opened or re-triggered), not a read operation (which would merely query alert status) and not destructive (the alert record is not deleted). While the server is described as 'read-only' overall, this tool performs a write action.

From the tool's definition Tool description states 'Resolve a fired alert — marks the underlying condition as handled.' This is a state-modifying operation that changes alert status from unresolved to resolved.

resolve_alert Rate-limited

resolve_alert stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
