WHAT IT DOES

What update_auth does on Webcake Storefront

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

RISK

Why update_auth is rated Medium

This tool creates or modifies authentication credentials and persists them to the local database, making it a Write operation. However, because credentials are foundational to system security and unauthorized modification could grant persistent access to the storefront, it rates 'high' severity rather than medium.

From the tool's definition Tool name 'update_auth' and description 'Update authentication credentials. All values are saved to local database' indicate modification of security-sensitive data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_auth safely

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

update_auth Rate-limited

update_auth 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.

What risk level is update_auth? +

Can I rate-limit update_auth? +

How do I block update_auth completely? +

Set action: deny in the PolicyLayer policy for update_auth. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
