A read-only MCP server that lets you explore and query any Gadget app's data via GraphQL — no generated client required. It supports multiple apps and both production/development environments.
List all models (list_models): Discover every model available in your Gadget app via GraphQL introspection.
Inspect model fields (introspect_model): View all fields and their types for any model — useful before querying to know what fields exist.
Query multiple records (query_records): Fetch records from any model with custom field selection, filtering (e.g., { "name": { "equals": "#59389" } }), and result limits (default 10, max 50).
Fetch a single record (get_record): Retrieve one specific record by its ID with custom field selection.
Run raw GraphQL queries (run_graphql): Execute arbitrary read-only GraphQL queries for complex use cases like nested relations or advanced filtering — mutations are blocked to enforce read-only access.
Provides tools to interact with Gadget applications via GraphQL, enabling users to list models, perform introspection, and execute read-only queries against application data.
Enables read-only access to Shopify-related data stored in Gadget apps, allowing users to query records such as Shopify orders and inspect Shopify-specific data models.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Gadget MCP Server show me the fields on the shopifyOrder model"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
