# get_discounts Fetch discount codes from the store Agent View of the PolicyLayer registry record for `get_discounts`. HTML page: https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/get-discounts ## Facts - Tool: `get_discounts` - Server: Shopify Graphql (`uvu-store/shopify-graphql-mcp`) — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp.md - Homepage: https://github.com/UVU-Store/shopify-graphql-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_discounts", "arguments": {} } } ``` ## Why get_discounts is rated Low The verb 'fetch' combined with the absence of any language suggesting creation, modification, deletion, or execution clearly indicates this is a read-only operation. Retrieving discount codes does not alter store state and poses minimal risk if misused by an AI agent, as it only exposes existing discount information. From the tool's own definition: "Tool name 'get_discounts' and description 'Fetch discount codes from the store' indicate a retrieval operation with no modification or side effects." ## Use case AI agents call get_discounts to retrieve information from Shopify Graphql without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Shopify Graphql: ```json { "version": "1", "default": "deny", "tools": { "get_discounts": {} } } ``` ## Other tools on Shopify Graphql (318) - `cancel_fulfillment_order` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/cancel-fulfillment-order.md - `cancel_order` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/cancel-order.md - `cancel_subscription_contract` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/cancel-subscription-contract.md - `delete_app_proxy` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-app-proxy.md - `delete_cart_transform` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-cart-transform.md - `delete_channel` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-channel.md - `delete_collection` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-collection.md - `delete_company` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-company.md - `delete_company_contact` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-company-contact.md - `delete_custom_fulfillment_service` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-custom-fulfillment-service.md - `delete_custom_pixel` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-custom-pixel.md - `delete_customer` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-customer.md - `delete_customer_address` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-customer-address.md - `delete_delivery_customization` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-delivery-customization.md - `delete_delivery_option_generator` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-delivery-option-generator.md - `delete_discount` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-discount.md - `delete_draft_order` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-draft-order.md - `delete_file` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-file.md - `delete_fulfillment_constraint_rule` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-fulfillment-constraint-rule.md - `delete_location` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-location.md - `delete_market` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-market.md - `delete_marketing_engagements` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-marketing-engagements.md - `delete_marketing_event` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-marketing-event.md - `delete_menu` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-menu.md - `delete_metaobject` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-metaobject.md - `delete_metaobject_definition` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-metaobject-definition.md - `delete_order` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-order.md - `delete_packing_slip_template` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-packing-slip-template.md - `delete_page` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-page.md - `delete_payment_customization` — Destructive — https://policylayer.com/tools/uvu-store-shopify-graphql-mcp/delete-payment-customization.md - …and 288 more: https://policylayer.com/tools/uvu-store-shopify-graphql-mcp.md ## For agents This record is a snapshot.
