WHAT IT DOES

What Update_Group does on Files Com

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

RISK

Why Update_Group is rated Medium

This tool modifies group configuration or metadata within Files.com. As an update operation, it creates reversible changes to existing resources. The severity is medium because unauthorized group modifications could affect access controls and user permissions, but the changes are not destructive (can be reverted) and do not directly move money or execute arbitrary code.

From the tool's definition Tool name is 'Update_Group' and description states 'Update Group'. Update operations modify existing data reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs Update_Group safely

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

Update_Group Rate-limited

Update_Group 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.
