Delete a database user from a CCX datastore. This is DESTRUCTIVE and may break applications using this user. You must set confirm to true. Use ccx_list_db_users first to see existing users and their host restrictions. Blocked by protection mode (CCX_PROTECT) by default.
AI agents call ccx_delete_db_user to permanently remove resources in Severalnines CCX MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool deletes database users, which is an irreversible operation that cannot be undone. It matches the Destructive category definition ('irreversibly deletes or overwrites data, or actions that cannot be undone'). The severity is high because deleting a user could break dependent applications and cause service disruption, though it is scoped to a single user rather than an entire datastore.
From the tool's definition Tool description explicitly states 'This is DESTRUCTIVE and may break applications using this user.' The tool permanently removes a database user, an irreversible action.
Attacks that exploit this kind of access
Delete a database user from a CCX datastore. This is DESTRUCTIVE and may break applications using this user. You must set confirm to true. Use ccx_list_db_users first to see existing users and their host restrictions. Blocked by protection mode (CCX_PROTECT) by default. It is categorised as a Destructive tool in the Severalnines CCX MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Severalnines CCX MCP Server MCP server in PolicyLayer and add a rule for ccx_delete_db_user: 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 Severalnines CCX MCP Server. Nothing to install.
ccx_delete_db_user 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 ccx_delete_db_user 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 ccx_delete_db_user. 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.
ccx_delete_db_user is provided by the Severalnines CCX MCP Server MCP server (severalnines/ccx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
