AI agents call delete-replication-group to permanently remove resources in Prometheus MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of a replication group is an irreversible operation that destroys data or infrastructure. This falls under Destructive rather than Execute because it specifically removes a resource entirely rather than triggering a side effect. The high severity reflects that losing a replication group could disrupt monitoring and observability.
From the tool's definition Tool name 'delete-replication-group' combined with server context (AWS Managed Prometheus) indicates permanent deletion of a replication group resource. The 'delete-' prefix is a clear indicator of destructive action.
Documented attack patterns abuse exactly the kind of access delete-replication-group gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Prometheus MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete-replication-group:
{
"version": "1",
"default": "deny",
"hide": [
"delete-replication-group"
]
}delete-replication-group disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

delete-replication-group. It is categorised as a Destructive tool in the Prometheus MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Prometheus MCP Server MCP server in PolicyLayer and add a rule for delete-replication-group: 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 Prometheus MCP Server. Nothing to install.
delete-replication-group 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-replication-group 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-replication-group. 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-replication-group is provided by the Prometheus MCP Server MCP server (awslabs.prometheus-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Prometheus MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
