AI agents call delete_agent_runtime to permanently remove resources in Awslabs Valkey — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The 'delete_' prefix strongly suggests this tool performs irreversible destruction of an agent runtime artifact. While the empty description limits certainty, the explicit use of 'delete' in the name aligns with the Destructive category (actions that cannot be undone). In a Valkey/cache context, deletion of runtime state could affect service availability.
From the tool's definition Tool name is 'delete_agent_runtime' with no description provided. The verb 'delete' indicates irreversible removal of data or system state (agent runtime).
Documented attack patterns abuse exactly the kind of access delete_agent_runtime gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Valkey, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_agent_runtime:
{
"version": "1",
"default": "deny",
"hide": [
"delete_agent_runtime"
]
}delete_agent_runtime disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

delete_agent_runtime. It is categorised as a Destructive tool in the Awslabs Valkey MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Awslabs Valkey MCP server in PolicyLayer and add a rule for delete_agent_runtime: 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 Awslabs Valkey. Nothing to install.
delete_agent_runtime 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 delete_agent_runtime 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 delete_agent_runtime. 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.
delete_agent_runtime is provided by the Awslabs Valkey MCP server (awslabs.valkey-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Awslabs Valkey, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
