Delete records from a table
AI agents call delete to permanently remove resources in Bun Database MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The delete tool performs irreversible deletion of database records. While the server claims built-in SQL injection prevention for parameterized queries, the delete operation itself has high blast radius: an AI agent with access to this tool could permanently remove critical business data, user records, or application state that cannot be recovered without backups.
From the tool's definition Tool name is 'delete' with description 'Delete records from a table'. This directly irreversibly removes data from a database.
Attacks that exploit this kind of access
Delete records from a table. It is categorised as a Destructive tool in the Bun Database MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Bun Database MCP Server 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 Bun Database MCP Server. 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 Bun Database MCP Server MCP server (ross-jill-ws/bun-db-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
