Delete one or more keys from Redis
AI agents call delete to permanently remove resources in Server Puppeteer — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data from a Redis store with no built-in undo capability. While the blast radius is scoped to Redis keys rather than entire databases or systems, deletion is irreversible and could cause significant data loss depending on what keys are targeted. High severity appropriate for destructive operations.
From the tool's definition Tool name is 'delete' with description 'Delete one or more keys from Redis'. The verb 'delete' and the explicit deletion of Redis keys indicates irreversible data removal.
Attacks that exploit this kind of access
Delete one or more keys from Redis. It is categorised as a Destructive tool in the Server Puppeteer MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Server Puppeteer 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 Server Puppeteer. 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 Server Puppeteer MCP server (@hisma/server-puppeteer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
