The final leg: it binds the verified Discord user to the Hanzo account that just signed in, and answers a short confirmation page telling them to return to Discord. The Hanzo credential is sealed into the connected org's KMS namespace rather than stored beside the link.

This is one leg of a three-leg flow, and the legs are not interchangeable: a browser is expected to arrive here only from the leg before it. The link URL's state proves the prompt was server-minted and carries the CHAT it started from — it is provenance only, and it never decides which account gets linked. The account identity always comes from the platform's own verified sign-in and a host-bound cookie, so forwarding a link to someone else cannot bind their account, and a session lifted into another browser is refused rather than completed. Each link is single-use, and a deployment without linking configured answers 503.

## Request

`GET /v1/provider/discord/link/callback` takes no parameters and no body — the credential is the whole request.

## Response

The document declares no response body for this operation. It answers `200` on success and the platform error shape on failure — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo provider discord link callback
```

**SDK**

**.ts**

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

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

**.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_discord_link_callback()
```

**.go**

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

resp, _, err := client.ProviderAPI.GetProviderDiscordLinkCallback(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_discord_link_callback(&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).getProviderDiscordLinkCallback();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/provider/discord/link/callback \
  -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"
         }
       }
     }'
```
