## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Lmnt MCP or direct API to generate audio, transform voice recordings, edit sound clips, and analyze speech through natural language.

## Summary

Lmnt is an AI-powered audio and voice manipulation platform for creative and technical sound work. It makes generating and transforming audio fast, flexible, and accessible for every developer.

## Categories

- ai & machine learning

## Toolkit Details

- Tools: 8

## Images

- Logo: https://logos.composio.dev/api/lmnt

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for LMNT.
  - Setup:
    - Configure Api Key credentials for LMNT.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- Generate a podcast intro in a new voice
- List all available AI voices for selection
- Synthesize this script using my preferred voice
- Update voice settings to sound more energetic

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `LMNT_CREATE_VOICE` | Create Voice | Creates a custom voice in LMNT by training on uploaded audio samples. The voice can then be used for text-to-speech synthesis. Returns the voice ID and metadata upon successful creation. The voice may be in 'training' state initially before becoming 'ready'. |
| `LMNT_DELETE_VOICE_INFO` | Delete Voice Info | Deletes a voice from your LMNT account. This operation permanently removes the voice and cancels any pending operations on it. This action cannot be undone. Only voices owned by you (owner='me') can be deleted; system voices cannot be deleted. Use case: Remove custom voices that are no longer needed to manage your voice library. |
| `LMNT_GENERATE_SPEECH_WITH_METADATA` | Generate Speech With Metadata | Generates speech from text and returns JSON with base64-encoded audio and optional word-level timing metadata. Use when you need the synthesis seed or word timestamps for subtitle synchronization. For lower latency without metadata, use the Synthesize Speech action instead. |
| `LMNT_GET_ACCOUNT` | Get Account | Retrieves account information including subscription plan details and current usage statistics. |
| `LMNT_GET_VOICE_INFO` | Get Voice Info | Gets metadata for a specific LMNT voice, including active status, supported languages, and plan availability. Useful for validating a voice ID before using it in synthesis requests. |
| `LMNT_GET_VOICES_LIST` | Get Voices List | Retrieves a list of available voices from LMNT. Returns both system-provided preset voices and any custom voices you have created. Use filters to narrow results by ownership (system vs custom) or starred status. Each voice includes details like ID, name, description, gender, state, and preview URL. |
| `LMNT_SYNTHESIZE_SPEECH` | Synthesize Speech | Synthesizes speech from text using LMNT's AI voices. Converts text (up to 5000 characters) into natural-sounding speech audio using a specified voice. Returns base64-encoded audio at `data.response_data.audio` — decode before saving or passing to other tools. Supports multiple audio formats and quality settings for different use cases. |
| `LMNT_UPDATE_VOICE` | Update Voice Info | Updates information about a specific voice in LMNT. You can update the name, description, gender, starred status, and unfreeze state of a voice. Note: Only user-owned voices (owner='me') can have their name, description, and gender updated. System voices can only be starred/unstarred. |

## 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 Lmnt Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Lmnt actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Synthesize speech from this text: "Welcome to the podcast!" using my preferred voice'
  }]
)
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: 'Synthesize speech from this text: "Welcome to the podcast!" using my preferred voice'
  }],
});
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 Lmnt tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Synthesize speech saying “Welcome to our demo” using the first available voice')
        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: 'Synthesize speech saying “Welcome to our demo” using the first available voice' }],
  stopWhen: stepCountIs( 5 )
});

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