WHAT IT DOES

What update_action does on Deloc

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

RISK

Why update_action is rated Medium

The tool creates or modifies data in a reversible manner (update operation) without permanently destroying resources or executing arbitrary code. It falls under Write category. Severity is medium because misconfigured actions in a deployment platform could cause service disruptions or expose credentials, but changes are typically reversible.

From the tool's definition Tool name is 'update_action' and description states 'Update an existing Action' — this modifies existing data reversibly.

Risk signalsBulk/mass operation — affects multiple targets

RECOMMENDED RULE

The rule that runs update_action safely

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

update_action Rate-limited

update_action 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.
