WHAT IT DOES

What renew_app does on Deloc

AI agents use renew_app 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 renew_app is rated Medium

Renewing an app extends its availability or trial period, modifying app state in a reversible manner. This falls under Write rather than Financial (no money moves) or Destructive (no data is deleted). The severity is medium because unintended renewals could extend service commitments or affect quota/resource allocation, but the effect is limited to a single app and reversible.

From the tool's definition Tool name 'renew_app' and description 'Extend a free-tier app' indicate modification of app lifecycle/subscription state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs renew_app 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 renew_app, this is the rule to start with:

renew_app Rate-limited

renew_app 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Deloc, apply this rule, and every renew_app call is checked against it from then on.
