| **Address**   | `https://api.hanzo.ai/v1/knowledge/connectors/catalog` |
| **Method**    | `GET`                                                  |
| **Operation** | `get_knowledge_connectors_catalog`                     |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`                 |

Returns the ONE catalog of everything a caller can
connect: every first-party connector and every long-tail one, in a single list
sorted by provider. `configured` reports whether this deployment holds OAuth
credentials for a source, so the console can show Connect rather than a dead
button, and `kind` is a badge only — the connect and sync lifecycle is
identical for both. The catalog itself is org-independent; a validated
principal is still required. It is metadata only: no secret is ever returned.

## Request

`GET /v1/knowledge/connectors/catalog` takes no parameters and no body — the credential is the whole request.

## Response

| Status    | Body                 | Meaning |
| --------- | -------------------- | ------- |
| `200`     | knowledge.catalogOut | ok      |
| `default` | problem-details      | refused |

`200` body — 6 fields.

| Field                      | In   | Type                      | Always | Description                                                                                                      |
| -------------------------- | ---- | ------------------------- | ------ | ---------------------------------------------------------------------------------------------------------------- |
| `connectors`               | body | knowledge.catalogEntry\[] | —      | Connectors is every connectable source, sorted by provider.                                                      |
| `connectors[].configured`  | body | boolean                   | —      | Configured is whether THIS DEPLOYMENT holds the OAuth client credentials for the provider.                       |
| `connectors[].description` | body | string                    | —      | Description is one line of shop copy: what connecting this source pulls in.                                      |
| `connectors[].displayName` | body | string                    | —      | DisplayName is the label to show a person.                                                                       |
| `connectors[].kind`        | body | string                    | —      | "native" \| "provider"                                                                                           |
| `connectors[].provider`    | body | string                    | —      | Provider is the source's id and the address every connector op takes it by (/v1/knowledge/connectors/:provider). |

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

## Examples

**CLI**

```bash
hanzo knowledge connectors catalog
```

**SDK**

**.ts**

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

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

**.py**

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

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

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new KnowledgeApi(client).getKnowledgeConnectorsCatalog();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/knowledge/connectors/catalog \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **knowledge** through the `knowledge` tool, which names its 9 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_knowledge_connectors"
         }
       }
     }'
```
