Grafbase is a serverless GraphQL platform that helps developers build and deploy data-driven applications faster. It provides a global data mesh, edge caching, and a CLI for local development. Developers building modern web and mobile applications use it to simplify data fetching and improve performance.

Use action names and parameters as needed.
This skill uses the Membrane CLI to interact with Grafbase. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.
Install the Membrane CLI so you can run membrane from the terminal:
npm install -g @membranehq/cli
membrane login --tenant
A browser window opens for authentication.
Headless environments: Run the command, copy the printed URL for the user to open in a browser, then complete with membrane login complete .
```bash
membrane search grafbase --elementType=connector --json
```
Take the connector ID from output.items[0].element?.id, then:
```bash
membrane connect --connectorId=CONNECTOR_ID --json
```
The user completes authentication in the browser. The output contains the new connection id.
When you are not sure if connection already exists:
```bash
membrane connection list --json
```
If a Grafbase connection exists, note its connectionId
When you know what you want to do but not the exact action ID:
membrane action list --intent=QUERY --connectionId=CONNECTION_ID --json
This will return action objects with id and inputSchema in it, so you will know how to run it.
| Name | Key | Description |
|---|---|---|
| --- | --- | --- |
| Get Available Mutations | get-available-mutations | List all available mutation operations in the schema |
| Get Available Queries | get-available-queries | List all available query operations in the schema |
| Execute Persisted Query | execute-persisted-query | Execute a persisted/trusted document query by its hash |
| Get Type Details | get-type-details | Get detailed information about a specific GraphQL type |
| List Schema Types | list-types | List all types defined in the GraphQL schema |
| Batch GraphQL Operations | batch-graphql-operations | Execute multiple GraphQL operations in a single request |
| Introspect Schema | introspect-schema | Fetch the GraphQL schema using introspection query |
| Execute GraphQL Mutation | graphql-mutation | Execute a GraphQL mutation against the Grafbase endpoint |
| Execute GraphQL Query | graphql-query | Execute a GraphQL query against the Grafbase endpoint |
membrane action run --connectionId=CONNECTION_ID ACTION_ID --json
To pass JSON parameters:
membrane action run --connectionId=CONNECTION_ID ACTION_ID --json --input "{ \"key\": \"value\" }"
When the available actions don't cover your use case, you can send requests directly to the Grafbase API through Membrane's proxy. Membrane automatically appends the base URL to the path you provide and injects the correct authentication headers — including transparent credential refresh if they expire.
membrane request CONNECTION_ID /path/to/endpoint
Common options:
| Flag | Description |
|---|---|
| ------ | ------------- |
-X, --method | HTTP method (GET, POST, PUT, PATCH, DELETE). Defaults to GET |
-H, --header | Add a request header (repeatable), e.g. -H "Accept: application/json" |
-d, --data | Request body (string) |
--json | Shorthand to send a JSON body and set Content-Type: application/json |
--rawData | Send the body as-is without any processing |
--query | Query-string parameter (repeatable), e.g. --query "limit=10" |
--pathParam | Path parameter (repeatable), e.g. --pathParam "id=123" |
membrane action list --intent=QUERY (replace QUERY with your intent) to find existing actions before writing custom API calls. Pre-built actions handle pagination, field mapping, and edge cases that raw API calls miss.共 2 个版本
