Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo provider slack channels
```

**SDK**

**.ts**

```ts
import { Configuration, ProviderApi } from 'hanzoai';

const api = new ProviderApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getProviderSlackChannels();
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import ProviderApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = ProviderApi(client).get_provider_slack_channels()
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.ProviderAPI.GetProviderSlackChannels(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, provider_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = provider_api::get_provider_slack_channels(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.ProviderApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new ProviderApi(client).getProviderSlackChannels();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/provider/slack/channels \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **provider** through the `provider` tool, which names its 38 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them:

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_connections"
         }
       }
     }'
```
