# DataWorks (dataworks-public)

Use Alibaba Cloud OpenAPI (RPC) with official SDKs or OpenAPI Explorer to manage all DataWorks resources. MCP Server is available as an alternative integration.

## Workflow

1. Confirm region, project/resource identifiers, and desired action.
2. Discover available APIs and required parameters (see API discovery below).
3. Call API via SDK.
4. Verify results with describe/list/get APIs.

### Troubleshooting fallback chain (follow this order)

If execution fails at any step, escalate to the next level:

1. **Cookbook** — check `references/cookbook.md` first. It contains verified API patterns, pitfalls, error recovery, the full end-to-end lifecycle (Create → Submit → Deploy → Run → Monitor), and reusable code snippets. Most common issues are already documented there.
2. **Official help docs** — read the API overview and per-API doc pages.
   - If an API call fails or the request/error is not understood, fetch the API directory page to locate the relevant API documentation:
     `https://help.aliyun.com/zh/dataworks/developer-reference/api-dataworks-public-2024-05-18-dir`
     Browse the category list, find the matching API name, and navigate to its detail page (URL pattern: `https://help.aliyun.com/zh/dataworks/developer-reference/api-dataworks-public-2024-05-18-{apinameincamelcase}`) for parameter details, error codes, and usage examples.
     For example, if `CreateNode` fails, find it under "数据开发（新版）" in the directory, then read its detail page: `https://help.aliyun.com/zh/dataworks/developer-reference/api-dataworks-public-2024-05-18-createnode`
3. **OpenAPI metadata** — fetch the raw JSON spec for exact parameter names, types, and required fields.
4. **SDK API docs** — check the typed SDK reference for correct method signatures and request classes.

- Java: `https://aliyunsdk-pages.alicdn.com/apidocs/{PRODUCT_CODE}/{API_VERSION}/java-async-tea/8.0.3/index.html`
- Node.js / Python: see `references/sources.md`

5. **GitHub source code** — read the Java SDK source for model/request class definitions: `https://github.com/aliyun/alibabacloud-java-sdk/tree/master/dataworks-public-20240518` (browse `src/main/java/com/aliyun/dataworks_public20240518/` for request/response models).
6. **MCP Server** — use the MCP Server to call APIs directly (see `references/mcp_server.md`).
7. **Browser** — use browser-use to visit the DataWorks Homepage (`https://dataworks.data.aliyun.com/${ALIBABA_CLOUD_REGION_ID}/#/index`) and inspect the UI behavior, network requests, or page content for clues.

## Credentials priority (must follow)

1. Environment variables: `ALIBABA_CLOUD_ACCESS_KEY_ID` / `ALIBABA_CLOUD_ACCESS_KEY_SECRET` / `ALIBABA_CLOUD_REGION_ID`
2. Credentials URI: `ALIBABA_CLOUD_CREDENTIALS_URI` (e.g. `http://localhost:7002/api/v1/credentials/0`). The SDK credentials provider automatically fetches and refreshes AK/SK/STS tokens from this HTTP endpoint.
3. Shared config file: `~/.alibabacloud/credentials`

Region policy: `ALIBABA_CLOUD_REGION_ID` is an optional default. If unset, decide the most reasonable region for the task; if unclear, ask the user.

## API discovery

Constants (use these values throughout):

- **PRODUCT_CODE**: `dataworks-public`
- **API_VERSION**: `2024-05-18`
- Use OpenAPI metadata endpoints to list APIs and get schemas (see references).

Do NOT rely on a hardcoded API list. Always discover APIs dynamically. Methods are listed in priority order — try them top-down:

### Method 1: Fetch from official help docs

Run the discovery script to curl the official documentation page and extract the complete API overview:

```bash
python scripts/fetch_api_overview.py
```

This fetches `https://help.aliyun.com/zh/dataworks/developer-reference/api-{PRODUCT_CODE}-{API_VERSION}-overview`, extracts the API list from `window.__ICE_PAGE_PROPS__.docDetailData.storeData.data.content`, and parses the HTML tables into a grouped API overview.

### Method 2: Fetch from OpenAPI metadata (full spec with parameters and responses)

Fetch raw API schemas and parameter definitions:

```bash
python scripts/list_openapi_meta_apis.py
```

This calls `https://next.api.aliyun.com/meta/v1/products/{PRODUCT_CODE}/versions/{API_VERSION}/api-docs.json` and outputs the full API docs JSON and a summary list.

To get the schema of a single API (replace `{ApiName}` with a name from the list above, e.g. `ListProjects`):

```
https://next.api.aliyun.com/meta/v1/products/{PRODUCT_CODE}/versions/{API_VERSION}/apis/{ApiName}/api.json
```

### Method 3: MCP Server tools (curated subset with category and parameter-position metadata)

If the MCP Server is running, use the MCP `tools/list` capability, or fetch `https://dataworks.data.aliyun.com/pop-mcp-tools` directly for the tool catalog JSON. Includes some APIs not in Method 2 (e.g. data service, permission approval).

## Calling APIs via SDK

**Recommend using the latest SDK version.** The DataWorks SDK is updated frequently with new APIs, bug fixes, and model changes. Check the latest version from the package registry before installing:

- Node.js: `https://www.npmjs.com/package/@alicloud/dataworks-public20240518`
- Python: `https://pypi.org/project/alibabacloud-dataworks-public20240518/`
- Java: `https://central.sonatype.com/artifact/com.aliyun/alibabacloud-dataworks_public20240518`

Prefer the official Alibaba Cloud SDK. Two styles are supported:

### Style 1: Generalized call (recommended, covers all APIs)

Use `@alicloud/openapi-client` to call any DataWorks API without importing product-specific SDK classes. This is the approach used by the MCP Server source code (`src/tools/callTool.ts`).

```bash
npm install @alicloud/openapi-client @alicloud/openapi-util @alicloud/tea-util @alicloud/credentials
```

```typescript
import OpenApi from "@alicloud/openapi-client";
import Util from "@alicloud/tea-util";

// 1. Create client
const config = new OpenApi.Config({
  accessKeyId: process.env.ALIBABA_CLOUD_ACCESS_KEY_ID,
  accessKeySecret: process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET,
  endpoint: `dataworks.${
    process.env.ALIBABA_CLOUD_REGION_ID || "cn-shanghai"
  }.aliyuncs.com`,
});
const client = new OpenApi.default(config);

// 2. Build request params (RPC style)
const params = new OpenApi.Params({
  style: "RPC",
  action: "ListProjects", // API name
  version: "{API_VERSION}", // see Constants above
  protocol: "HTTPS",
  method: "POST", // GET or POST per API spec
  authType: "AK",
  pathname: "/",
  bodyType: "json",
});

// 3. Build query/body from input
const query = { PageNumber: 1, PageSize: 10 };
const request = new OpenApi.OpenApiRequest({ query });
const runtime = new Util.RuntimeOptions({});

// 4. Call
const res = await client.callApi(params, request, runtime);
console.log(res.body);
```

Key rules from `src/tools/callTool.ts`:

- `style`: `'RPC'` when API has no path; `'ROA'` when it has a path.
- `method`: per API spec (`GET` / `POST` / `PUT` / `DELETE`).
- Parameters with `in: 'query'` go to `query`; `in: 'body'` / `in: 'formData'` go to `body`.
- For `GET` / `DELETE` requests, `body` must be `null` (otherwise signature fails).
- Use `bodyType: 'string'` to avoid precision loss on large numbers.

### Style 2: Product-specific SDK (typed, per-API methods)

```bash
npm install @alicloud/dataworks-public20240518
```

```typescript
import DataWorks from "@alicloud/dataworks-public20240518";
import * as DataWorksClasses from "@alicloud/dataworks-public20240518";
import OpenApi from "@alicloud/openapi-client";

const config = new OpenApi.Config({
  accessKeyId: process.env.ALIBABA_CLOUD_ACCESS_KEY_ID,
  accessKeySecret: process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET,
  endpoint: `dataworks.cn-shanghai.aliyuncs.com`,
});
const client = new DataWorks.default(config);

// Each API has a typed Request class and a method
const request = new DataWorksClasses.ListProjectsRequest({
  pageNumber: 1,
  pageSize: 10,
});
const runtime = new Util.RuntimeOptions({});
const resp = await client.listProjectsWithOptions(request, runtime);
```

API name → SDK method: `ListProjects` → `client.listProjectsWithOptions(request, runtime)`.

### Python SDK

```bash
pip install alibabacloud_dataworks_public20240518
```

```python
import os
from alibabacloud_dataworks_public20240518.client import Client
from alibabacloud_dataworks_public20240518 import models
from alibabacloud_tea_openapi.models import Config

config = Config(
    access_key_id=os.environ['ALIBABA_CLOUD_ACCESS_KEY_ID'],
    access_key_secret=os.environ['ALIBABA_CLOUD_ACCESS_KEY_SECRET'],
    endpoint=f"dataworks.{os.environ.get('ALIBABA_CLOUD_REGION_ID', 'cn-shanghai')}.aliyuncs.com",
)
client = Client(config)
request = models.ListProjectsRequest(page_number=1, page_size=10)
resp = client.list_projects(request)
print(resp.body)
```

### Java SDK

```xml
<dependency>
    <groupId>com.aliyun</groupId>
    <artifactId>alibabacloud-dataworks_public20240518</artifactId>
    <version>8.0.3</version>
</dependency>
```

```java
import com.aliyun.dataworks_public20240518.Client;
import com.aliyun.dataworks_public20240518.models.*;
import com.aliyun.teaopenapi.models.Config;

Config config = new Config()
    .setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"))
    .setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"))
    .setEndpoint("dataworks." + System.getenv("ALIBABA_CLOUD_REGION_ID") + ".aliyuncs.com");
Client client = new Client(config);

ListProjectsRequest request = new ListProjectsRequest()
    .setPageNumber(1L)
    .setPageSize(10L);
ListProjectsResponse resp = client.listProjects(request);
System.out.println(resp.getBody());
```

## MCP Server integration (last resort)

Only use MCP when SDK calls keep failing after consulting docs, metadata, and GitHub source:

```bash
npm install -g alibabacloud-dataworks-mcp-server
```

See `references/mcp_server.md` for full configuration.

Use dynamic discovery (above) to get the full list and parameter schemas. Common naming patterns:

1. Inventory/list: prefer `List*` / `Get*` / `Describe*` APIs.
2. Create/configure: prefer `Create*` / `Update*` / `Import*` APIs.
3. Remove: prefer `Delete*` / `Remove*` APIs.
4. Lifecycle: prefer `Start*` / `Stop*` / `Suspend*` / `Resume*` / `Rerun*` APIs.

## Destructive operation policy

Before executing delete, stop, or suspend operations, always summarize the affected resources and confirm with the user.

## Timestamp handling

DataWorks APIs use millisecond timestamps. Convert between human-readable dates and timestamps as needed.

## Selection questions (ask when unclear)

1. Which DataWorks project (project ID or name)?
2. Which region? (common: `cn-shanghai`, `cn-beijing`, `cn-hangzhou`, `cn-shenzhen`)
3. What type of operation? (data development / operations / data quality / metadata / workspace)
4. For task operations: target node ID, workflow, or instance ID?
