Drop a table
AI agents call drop_table to permanently remove resources in PostgreSQL MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
DROP TABLE is a destructive operation that permanently deletes a table and all contained data. This is the most severe category per the rules, as it irreversibly removes data. The critical severity reflects the maximal blast radius: an AI agent misusing this tool could destroy entire database tables with no undo capability, requiring restoration from backup to recover.
From the tool's definition Tool name is 'drop_table' with description 'Drop a table'. The DROP TABLE SQL command permanently removes a table and all its data, which is irreversible and cannot be undone without restoration from backup.
Attacks that exploit this kind of access
Drop a table. It is categorised as a Destructive tool in the PostgreSQL MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the PostgreSQL MCP Server MCP server in PolicyLayer and add a rule for drop_table: 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 PostgreSQL MCP Server. Nothing to install.
drop_table 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 drop_table 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 drop_table. 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.
drop_table is provided by the PostgreSQL MCP Server MCP server (reckersai/mcpg). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
