Delete one or more Redis keys
AI agents call redis_del to permanently remove resources in Mcp Database — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Redis key deletion is a destructive operation that cannot be undone. Once keys are deleted, the data is permanently lost unless separately backed up. While the blast radius depends on which keys an agent targets, the operation itself is fundamentally irreversible, placing it in the Destructive category rather than Write (which is reversible).
From the tool's definition Tool name explicitly states 'del' (delete) and description confirms 'Delete one or more Redis keys' — irreversible removal of data from Redis.
Attacks that exploit this kind of access
Delete one or more Redis keys. It is categorised as a Destructive tool in the Mcp Database MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Database MCP server in PolicyLayer and add a rule for redis_del: 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 Mcp Database. Nothing to install.
redis_del 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 redis_del 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 redis_del. 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.
redis_del is provided by the Mcp Database MCP server (nam088/mcp-database-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
