THE RISK

Critical Risk

Why delete-serverless-cache needs a policy

The 'delete' verb combined with 'serverless-cache' indicates this tool performs irreversible deletion of cached data. Even without a detailed description, 'delete' operations are classified as Destructive per the rules. The severity is high rather than critical because the blast radius is limited to cache (typically non-persistent data), though cache deletion could disrupt service performance.

From the tool's definition Tool name is 'delete-serverless-cache' which explicitly contains 'delete' indicating irreversible removal of cache data. Description is empty, preventing full assessment of scope.

POLICY

How to control delete-serverless-cache

PolicyLayer is an MCP gateway — it sits between your AI agents and CloudWatch Application Signals MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete-serverless-cache:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete-serverless-cache"
  ]
}

delete-serverless-cache disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register CloudWatch Application Signals MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
