Delete one or more keys from Redis
AI agents call delete to permanently remove resources in Helm Chart CLI — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of Redis keys cannot be undone without a backup. This is a destructive operation with high blast radius if an AI agent mistakenly deletes critical cache data, session stores, or other persistent Redis entries. Destructive category takes precedence over Write or Execute.
From the tool's definition Tool name is 'delete' and description states 'Delete one or more keys from Redis' — this irreversibly removes data from a Redis store.
Attacks that exploit this kind of access
Delete one or more keys from Redis. It is categorised as a Destructive tool in the Helm Chart CLI MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Helm Chart CLI MCP server in PolicyLayer and add a rule for delete: 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 Helm Chart CLI. Nothing to install.
delete 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 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. 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 is provided by the Helm Chart CLI MCP server (jeff-nasseri/servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
