| **Address**   | `https://api.hanzo.ai/v1/tool/plugins` |
| **Method**    | `GET`                                  |
| **Operation** | `get_tool_plugins`                     |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY` |

Reports what this deployment actually mounted: every subsystem the
composition root declared and whether it is switched on. A plugin here is
MOUNTED CODE that extends the deployment's own surface — not a tool an agent
calls — so this is an inventory and not a tool source. It is read off the same
boot snapshot every traced request resolves its subsystem label against, so it
cannot drift from what is serving. Enabled-only by default, because a caller
asking what this deployment can do wants what is running; ?all=true adds the
configured-but-off ones.

## Request

1 field.

| Field | In    | Type   | Required | Description                                                                                             |
| ----- | ----- | ------ | -------- | ------------------------------------------------------------------------------------------------------- |
| `all` | query | string | —        | All includes the configured-but-disabled subsystems too, but only when it is exactly the string "true". |

## Response

| Status    | Body                 | Meaning |
| --------- | -------------------- | ------- |
| `200`     | tool.pluginMountList | ok      |
| `default` | problem-details      | refused |

`200` body — 4 fields.

| Field                | In   | Type                | Always | Description                                                                                             |
| -------------------- | ---- | ------------------- | ------ | ------------------------------------------------------------------------------------------------------- |
| `plugins`            | body | tool.pluginMount\[] | —      | Plugins is every subsystem the composition root declared, filtered to the enabled ones unless all=true. |
| `plugins[].enabled`  | body | boolean             | —      | Enabled is whether this subsystem is switched on in this deployment.                                    |
| `plugins[].name`     | body | string              | —      | Name is the subsystem's name, the same label a traced request resolves to.                              |
| `plugins[].prefixes` | body | string\[]           | —      | Prefixes are the URL prefixes this subsystem serves.                                                    |

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

## Examples

**CLI**

```bash
hanzo tool plugins get
```

**SDK**

**.ts**

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

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

**.py**

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

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

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new ToolApi(client).getToolPlugins();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/tool/plugins \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **tool** through the `tool` tool, which names its 17 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_tools"
         }
       }
     }'
```
