Drop an index
AI agents call db_drop_index to permanently remove resources in Database MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The 'drop' operation removes a database index permanently and cannot be undone without manual recreation or restoration from backups. This is a destructive action that alters the database schema irreversibly. While not as severe as dropping a table (which would lose data), dropping an index degrades query performance and cannot be reversed transactionally.
From the tool's definition Tool name 'db_drop_index' and description 'Drop an index' indicate irreversible deletion of a database index.
Attacks that exploit this kind of access
Drop an index. It is categorised as a Destructive tool in the Database MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Database MCP Server MCP server in PolicyLayer and add a rule for db_drop_index: 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 Database MCP Server. Nothing to install.
db_drop_index 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 db_drop_index 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 db_drop_index. 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.
db_drop_index is provided by the Database MCP Server MCP server (roilanrodriguez55/database-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
