Delete a metaobject definition. Also deletes all related metafield definitions, metaobjects, and metafields asynchronously.
AI agents call delete_metaobject_definition to permanently remove resources in Shopify Graphql — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool irreversibly deletes metaobject definitions and cascades deletion to all related metafields and metaobjects. This is a destructive operation that cannot be undone, affecting potentially significant amounts of structured data in a Shopify store. The async nature and cascade scope elevate risk from Write to Destructive.
From the tool's definition 'Delete a metaobject definition. Also deletes all related metafield definitions, metaobjects, and metafields asynchronously.' — explicitly describes deletion of data structures and all dependent data.
Attacks that exploit this kind of access
Delete a metaobject definition. Also deletes all related metafield definitions, metaobjects, and metafields asynchronously. It is categorised as a Destructive tool in the Shopify Graphql MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Shopify Graphql MCP server in PolicyLayer and add a rule for delete_metaobject_definition: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Shopify Graphql. Nothing to install.
delete_metaobject_definition is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_metaobject_definition rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_metaobject_definition. 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.
delete_metaobject_definition is provided by the Shopify Graphql MCP server (uvu-store/shopify-graphql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
