## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `MSG91_CREATE_USER_EVENTS` | Create User Events | Create and track user events in MSG91 Segmento for customer behavior analysis and segmentation. Use this tool to record user actions and behaviors such as logins, purchases, page views, button clicks, or any custom events. These events help build user profiles and enable targeted campaigns based on user behavior. Examples: - Track user login events for engagement analysis - Record purchase events with product details for sales tracking - Log page views and clicks for behavior analytics - Capture custom events with properties for detailed segmentation |
| `MSG91_GET_EVENT_TYPES` | Get Event Types | Retrieves all event types configured in MSG91 Segmento. Event types represent different user actions and behaviors that can be tracked (e.g., purchases, signups, page views). Use this action to discover what events are available for tracking user behavior in your Segmento account. No parameters required - returns all event types. |
| `MSG91_GET_FAILED_EVENTS` | Get Failed Events | Retrieve failed user events from a MSG91 Segmento campaign. This tool fetches events that failed to process during campaign execution, helping you identify and debug issues such as validation errors, invalid recipients, or missing required data. Use this when you need to: - Investigate why certain events didn't process successfully - Get detailed failure reasons for troubleshooting - Monitor campaign health and identify patterns in failures - Retrieve failed events within a specific date range Results are paginated for large datasets. Requires a valid campaign_id from a Segmento campaign. |
| `MSG91_LIST_CAMPAIGNS` | List Campaigns | Tool to list all campaigns in Segmento. Use when you need to retrieve campaigns with pagination support. |
| `MSG91_RESEND_OTP` | Resend OTP | Resend OTP to the same mobile number via text message or voice call. Use when the original OTP was not received or expired, and the user needs a new code sent to the same number. |
| `MSG91_SEND_OTP` | Send OTP | Tool to send OTP (One-Time Password) to a mobile number using a pre-configured MSG91 template. Use when you need to verify user phone numbers for authentication, account registration, password reset, or transaction confirmation. |
| `MSG91_SEND_SMS_V5` | Send SMS via Flow (V5) | Send SMS messages using pre-defined templates via MSG91 Flow API v5. Use when you need to send template-based SMS with dynamic variable substitution to single or multiple recipients. Templates must be created and approved in MSG91 dashboard before use. |
| `MSG91_VERIFY_OTP` | Verify OTP | Tool to verify an OTP (One-Time Password) sent to a mobile number. Use when you need to confirm that the OTP code entered by the user matches the one sent via Send OTP API. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK
```python
pip install composio_openai
```

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

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

Import and initialize Composio client, then create a 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')
```

```typescript
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 Msg91 Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Msg91 actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Send an SMS to confirm today\'s appointment'
  }]
)
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: 'Send an SMS to confirm today\'s appointment'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and Claude Agent SDK
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

#### Path 2, Step 2: Create Tool Router Session

Initialize the Composio client and create a Tool Router session
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')
url = session.mcp.url
```

```typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });

console.log("Creating Tool Router session...");
const { mcp } = await composio.create('your-user-id');
console.log(`Tool Router session created: ${mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Msg91 tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Send SMS to +1234567890 with appointment reminder')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

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({
  transport: {
    type: 'http',
    url: mcp.url,
    headers: { 'x-api-key': 'your-composio-api-key' }
  }
});

const tools = await client.tools();

const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{ role: 'user', content: 'Send SMS to +1234567890 with appointment reminder' }],
  stopWhen: stepCountIs(5)
});

console.log(`Agent: ${text}`);
```
