WHAT IT DOES

What nfs_config_update does on Nasbridge

AI agents use nfs_config_update to create or update resources in Nasbridge, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nasbridge environment.

RISK

Why nfs_config_update is rated Medium

This tool modifies NFS configuration globally, affecting network services and access controls across the TrueNAS system. While reversible (configuration can be changed back), incorrect NFS settings could disrupt network file sharing, create security vulnerabilities, or impact system availability.

From the tool's definition Tool name 'nfs_config_update' combined with description 'Update global NFS configuration' indicates modification of system configuration settings.

RECOMMENDED RULE

The rule that runs nfs_config_update safely

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

nfs_config_update Rate-limited

nfs_config_update stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
