THE RISK

Critical Risk

Why delete_datastore needs a policy

Deletion of a data store is an irreversible operation that cannot be undone. This falls squarely into the Destructive category as it permanently removes data. The severity is high because deleting a data store in a healthcare imaging system could result in loss of critical medical data, affecting patient care and compliance.

From the tool's definition Tool name is 'delete_datastore' and description states 'Delete a data store from AWS HealthImaging'. The verb 'delete' combined with 'data store' indicates irreversible removal of data.

POLICY

How to control delete_datastore

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_datastore:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_datastore"
  ]
}

delete_datastore disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register AWS — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on delete_datastore? +

Register the AWS MCP server in PolicyLayer and add a rule for delete_datastore: 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 AWS. Nothing to install.

What risk level is delete_datastore? +

How do I block delete_datastore completely? +

Set action: deny in the PolicyLayer policy for delete_datastore. 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.

What MCP server provides delete_datastore? +

delete_datastore is provided by the AWS MCP server (@awslabs/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
