WHAT IT DOES

What accept_invitation does on Webcake Storefront

AI agents use accept_invitation 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 accept_invitation is rated Medium

Accepting an invitation is a Write operation that creates a new access/membership record for a site. It is reversible (the user could be removed later), but grants access to a site, which could have meaningful security implications if misused. No data is deleted, no code is executed, and no financial transaction occurs.

From the tool's definition Accept a site invitation — 'accept' implies confirming/activating an invitation, creating a membership or access relationship

Attacks that exploit this kind of access

RECOMMENDED RULE

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

accept_invitation Rate-limited

accept_invitation 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.
