WHAT IT DOES

What kinsta.tools.clear-cache does on Kinsta MCP Server

AI agents invoke kinsta.tools.clear-cache to trigger actions in Kinsta MCP Server. 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.

WHY IT NEEDS A POLICY

Why kinsta.tools.clear-cache needs a policy

Clearing cache triggers an external operation on the server infrastructure. It is not a simple data read or write — it actively purges cached data and initiates a server-side operation (evidenced by returning an operation_id). While cache clearing is generally recoverable (cache rebuilds over time), it can cause temporary performance degradation or expose origin servers to increased load.

From the tool's definition Clear the server cache for an environment. Returns an operation_id.
