WHAT IT DOES

What wafle_resources_invalidate does on wafle MCP server

AI agents invoke wafle_resources_invalidate to trigger actions in wafle 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 wafle_resources_invalidate needs a policy

This tool triggers an operational action (cache invalidation) that affects the MCP server's in-memory state. It's not a simple read, nor does it permanently delete data, but it executes a side-effecting operation that clears cached resources, potentially causing downstream performance impacts or forcing re-fetches. Misuse could cause repeated cache thrashing or service disruption.
