## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `TELNYX_CREATE_NETWORK` | Create Network | Tool to create a new network. Use when you need to provision a fresh network resource before connecting devices. |
| `TELNYX_CREATE_NOTIFICATION_CHANNEL` | Create Notification Channel | Tool to create a notification channel. Use when you need to register a channel (SMS, voice, email, or webhook) to receive notifications. E.g., create a webhook channel for event callbacks. |
| `TELNYX_CREATE_NOTIFICATION_PROFILE` | Create Notification Profile | Tool to create a notification profile. Use when you need to register a new profile to group notification channels (SMS and voice) and define notification settings. Must be called before TELNYX_CREATE_NOTIFICATION_CHANNEL, as channel creation requires the notification_profile_id returned by this tool. |
| `TELNYX_CREATE_NOTIFICATION_SETTING` | Create Notification Setting | Tool to add a notification setting. Use after creating the event condition, profile, and channel. All three UUID parameters must be fetched dynamically from their respective list/create endpoints; hardcoded IDs are not portable across accounts. |
| `TELNYX_DELETE_NETWORK` | Delete Network | Tool to delete a network by ID. Use when you have obtained the network's identifier and need to remove it permanently. |
| `TELNYX_DELETE_NOTIFICATION_CHANNEL` | Delete Notification Channel | Tool to delete a notification channel by ID. Use when you have the channel's identifier and need to remove it permanently. |
| `TELNYX_DELETE_NOTIFICATION_PROFILE` | Delete Notification Profile | Tool to delete a notification profile by ID. Use when you have the profile's identifier and need to remove it permanently. |
| `TELNYX_DELETE_NOTIFICATION_SETTING` | Delete Notification Setting | Tool to delete a notification setting by ID. Use when you need to permanently remove an existing notification setting before reconfiguration. |
| `TELNYX_GET_BLACK_BOX_TEST_RESULTS` | Get Black Box Test Results | Tool to retrieve black box test results from Telnyx SETI Observability. Use when you need to check service health and test results, optionally filtering by product. |
| `TELNYX_GET_USER_BALANCE` | Get User Balance | Tool to retrieve the current user account balance and credit details. Use after authenticating your account to check available balance. |
| `TELNYX_LIST_AUDIT_LOGS` | List Audit Logs | Tool to retrieve a list of audit log entries for your account. Use when you need to review recent resource changes with optional pagination and date filters. |
| `TELNYX_LIST_CONNECTIONS` | List Connections | Tool to retrieve all connections in your account. Use when you need to list connections with pagination, filtering, and sorting. |
| `TELNYX_LIST_DYNAMIC_EMERGENCY_ENDPOINTS` | List Dynamic Emergency Endpoints | Tool to list dynamic emergency endpoints. Use when you need to retrieve dynamic emergency endpoint records, optionally filtered by status or country. Example: "List all activated endpoints in US". |
| `TELNYX_LIST_GLOBAL_IP_HEALTH_CHECK_TYPES` | List Global IP Health Check Types | Tool to list all available global IP health check types. Use when you need to retrieve supported health check types for global IP configurations. |
| `TELNYX_LIST_MESSAGING_PROFILES` | List Messaging Profiles | Tool to list messaging profiles. Use when you need to retrieve messaging profiles with optional pagination. |
| `TELNYX_LIST_MESSAGING_URL_DOMAINS` | List Messaging URL Domains | Tool to list configured messaging URL domains. Use when you need to retrieve messaging URL domains for a profile. |
| `TELNYX_LIST_MOBILE_NETWORK_OPERATORS` | List Mobile Network Operators | Tool to list available mobile network operators. Use when you need to discover operators optionally filtered by country code, operator name, or with pagination. |
| `TELNYX_LIST_NETWORK_INTERFACES` | List Network Interfaces | Tool to list all network interfaces for a specified network. Use after retrieving a network's ID to enumerate its interfaces. |
| `TELNYX_LIST_NETWORKS` | List Networks | Tool to list all networks in your account. Use when you need to retrieve networks with optional pagination and filtering. |
| `TELNYX_LIST_NOTIFICATION_CHANNELS` | List Notification Channels | Tool to list all notification channels. Use when you need to retrieve and paginate existing notification channels, optionally filtering by channel type. |
| `TELNYX_LIST_NOTIFICATION_EVENT_CONDITIONS` | List Notification Event Conditions | Tool to list all notification event conditions. Use when you need to retrieve and paginate notification event conditions, optionally filtering by associated record type. |
| `TELNYX_LIST_NOTIFICATION_EVENTS` | List Notification Events | Tool to list all notification events with their IDs. Use to dynamically retrieve notification_event_condition_id values before configuring webhook subscriptions — IDs are account-specific and must not be hardcoded, as stale IDs silently prevent events (e.g., call routing, recording) from reaching the webhook. |
| `TELNYX_LIST_NOTIFICATION_PROFILES` | List Notification Profiles | Tool to list all notification profiles. Use when you need to retrieve and paginate your notification profiles with optional pagination. |
| `TELNYX_LIST_PHONE_NUMBERS` | List Phone Numbers | Tool to list phone numbers associated with your account. Use when you need to retrieve and filter your phone numbers with optional pagination and sorting. |
| `TELNYX_LIST_SSO_AUTHENTICATION_PROVIDERS` | List SSO Authentication Providers | Tool to retrieve all configured SSO authentication providers. Use after authenticating to enumerate your organization's SSO providers. |
| `TELNYX_RETRIEVE_NETWORK` | Retrieve Network | Tool to retrieve details of a specific network by ID. Use after obtaining the network's identifier to fetch its current attributes before update or delete operations. |
| `TELNYX_RETRIEVE_NOTIFICATION_CHANNEL` | Retrieve Notification Channel | Tool to retrieve a notification channel by ID. Use after you have a channel ID and need its details, such as name, type, and status. |
| `TELNYX_RETRIEVE_NOTIFICATION_PROFILE` | Retrieve Notification Profile | Tool to retrieve a notification profile by ID. Use after obtaining the profile ID when you need details about its webhook endpoints and subscribed events. |
| `TELNYX_RETRIEVE_NOTIFICATION_SETTING` | Retrieve Notification Setting | Tool to retrieve a notification setting by ID. Use after obtaining the notification setting ID to fetch its details, such as status, parameters, and associated channel. |
| `TELNYX_UPDATE_NETWORK` | Update Network | Tool to update details of an existing network. Use when you have a network's identifier and need to modify its name or tags. |

```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Telnyx Tools via Tool Router with Your Agent

  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'Check my current Telnyx account balance and recent audit logs.'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Telnyx tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Get current user account balance from Telnyx')
        async for message in client.receive_response():
            if hasattr(message, 'content'):

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText, stepCountIs } from 'ai';

const client = await createMCPClient({
