删除键
AI agents call key_delete to permanently remove resources in Redis MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data from Redis. Even though individual key deletion may have limited blast radius compared to db_flush, it is categorized as Destructive (the most severe applicable category) because the action cannot be undone and results in permanent data loss.
From the tool's definition Tool name 'key_delete' with description '删除键' (Chinese: 'delete key') performs irreversible deletion of data from Redis database.
Attacks that exploit this kind of access
删除键. It is categorised as a Destructive tool in the Redis MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Redis MCP server in PolicyLayer and add a rule for key_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 Redis MCP. Nothing to install.
key_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 key_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 key_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.
key_delete is provided by the Redis MCP server (pickstar-2002/redis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
key_delete is one line of Redis's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
