WHAT IT DOES

What revoke_range_access does on Ludus FastMCP

AI agents call revoke_range_access to permanently remove resources in Ludus FastMCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why revoke_range_access is rated Critical

Revoking access is a destructive/irreversible action in the access control sense: once revoked, the user loses all access to the range and any associated state or context tied to that access grant. This cannot be undone automatically and has significant impact on a user's ability to operate within the environment.

From the tool's definition 'Revoke range access from a user' — revocation of access is an irreversible administrative action that removes a user's ability to access the cyber range environment

RECOMMENDED RULE

The rule that runs revoke_range_access safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ludus FastMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For revoke_range_access, this is the rule to start with:

revoke_range_access Hidden

revoke_range_access is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
