Delete multiple values from the cache (alias for delete_many).
AI agents call cache_delete_multi to permanently remove resources in AWS Transform MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes data from a cache system. Deletion is a destructive operation that cannot be undone. The 'multiple values' scope amplifies the blast radius. While this is less critical than deleting production databases, the irreversible removal of cached data without recovery options justifies the Destructive category and high severity rating.
From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete multiple values from the cache'. The alias reference 'delete_many' reinforces the destructive nature of the operation.
Documented attack patterns abuse exactly the kind of access cache_delete_multi gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Transform MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for cache_delete_multi:
{
"version": "1",
"default": "deny",
"hide": [
"cache_delete_multi"
]
}cache_delete_multi disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete multiple values from the cache (alias for delete_many). It is categorised as a Destructive tool in the AWS Transform MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the AWS Transform MCP Server MCP server in PolicyLayer and add a rule for cache_delete_multi: 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 AWS Transform MCP Server. Nothing to install.
cache_delete_multi is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the cache_delete_multi 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.
Set action: deny in the PolicyLayer policy for cache_delete_multi. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
cache_delete_multi is provided by the AWS Transform MCP Server MCP server (awslabs.aws-transform-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AWS Transform MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
