What create_company does on Shopify Graphql
AI agents use create_company to create or update resources in Shopify Graphql, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Shopify Graphql environment.
Why create_company is rated Medium
Creating a new company record is a reversible write operation. It modifies the store's data by adding a new entity, but does not delete data, execute arbitrary code, or move money. The blast radius is medium because a malicious actor could create fake or spam company accounts, but the operation itself is not destructive or financial in nature.
From the tool's definition Tool name is 'create_company' and description states 'Create a new B2B company' — this is a create operation that adds new data to the Shopify store.
Attacks that exploit this kind of access
The rule that runs create_company safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Shopify Graphql, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_company, this is the rule to start with:
create_company 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 Shopify Graphql, apply this rule, and every create_company call is checked against it from then on.
