Why remove_user_from_group needs a policy

Removing a user from a group revokes their access permissions, which is effectively irreversible without knowing the prior state. This is a destructive operation on access control. The empty description lowers confidence, but the name strongly implies this action. Severity is high because misuse could revoke legitimate access for users.

From the tool's definition Tool name 'remove_user_from_group' implies removing a user from a group, which is an irreversible IAM/access control modification. Description is empty, lowering confidence.

POLICY

How to control remove_user_from_group

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

policy.json

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

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