delete
AI agents call delete to permanently remove resources in Pgmcp — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Despite the empty description, the tool name 'delete' combined with the server's PostgreSQL administration context and sibling destructive tools (destroy_corpus, destroy_document, drop_function) makes it highly probable this tool performs irreversible deletion. The critical severity reflects the potential to permanently lose data without recovery.
From the tool's definition Tool named 'delete' with no description, operating on a PostgreSQL administration server alongside tools like 'destroy_corpus', 'destroy_document', and 'drop_function'. The naming convention and context strongly indicate irreversible data deletion.
Attacks that exploit this kind of access
delete. It is categorised as a Destructive tool in the Pgmcp MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Pg 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 Pgmcp. 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 Pg MCP server (veloper/pgmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
