Deletes a Timestream for InfluxDB DB instance by the instance-identifier
AI agents call DeleteDbInstance to permanently remove resources in AWS Well-Architected Security Assessment Tool MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a database instance and cannot be undone. It meets the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' While high rather than critical (as blast radius depends on the specific instance and its data criticality), deletion of a database instance represents a severe irreversible action.
From the tool's definition Tool name 'DeleteDbInstance' explicitly indicates deletion. Description states 'Deletes a Timestream for InfluxDB DB instance' — a permanent, irreversible operation on a database resource.
Documented attack patterns abuse exactly the kind of access DeleteDbInstance gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Well-Architected Security Assessment Tool MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for DeleteDbInstance:
{
"version": "1",
"default": "deny",
"hide": [
"DeleteDbInstance"
]
}DeleteDbInstance disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Yes. Add a rate_limit block to the DeleteDbInstance 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 DeleteDbInstance. 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.
DeleteDbInstance is provided by the AWS Well-Architected Security Assessment Tool MCP Server MCP server (awslabs.well-architected-security-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
