## Introduction

This guide walks you through connecting Lmnt to the Claude Agent SDK using the Composio tool router. By the end, you'll have a working Lmnt agent that can generate a podcast intro in a new voice, list all available ai voices for selection, synthesize this script using your preferred voice through natural language commands.
This guide will help you understand how to give your Claude Agent SDK agent real control over a Lmnt account through Composio's Lmnt MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Get and set up your Claude/Anthropic and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Lmnt
- Configure an AI agent that can use Lmnt as a tool
- Run a live chat session where you can ask the agent to perform Lmnt operations

## What is Claude Agent SDK?

The Claude Agent SDK is Anthropic's official framework for building AI agents powered by Claude. It provides a streamlined interface for creating agents with MCP tool support and conversation management.
Key features include:
- Native MCP Support: Built-in support for Model Context Protocol servers
- Permission Modes: Control tool execution permissions
- Streaming Responses: Real-time response streaming for interactive applications
- Context Manager: Clean async context management for sessions

## What is the Lmnt MCP server, and what's possible with it?

The Lmnt MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Lmnt account. It provides structured and secure access to your voice and audio management features, so your agent can perform actions like creating voices, synthesizing speech, retrieving or updating voice profiles, and managing your audio assets on your behalf.
- Custom voice creation and management: Direct your agent to create new voice profiles or update existing ones for use in voice synthesis and transformation.
- Real-time speech synthesis: Instantly generate lifelike speech from text using your selected voice models for creative or technical projects.
- Voice library retrieval: Have your agent fetch and list all available voices in your Lmnt account, making it easy to explore or switch between options.
- Voice info review and deletion: Pull detailed information about any voice profile or let your agent remove unused voices to keep your workspace organized.
- Account insights and status checks: Allow your agent to retrieve your Lmnt account details, ensuring smooth integration and monitoring of usage or settings.

## 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. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Lmnt MCP server is an implementation of the Model Context Protocol that connects your AI agent to Lmnt. It provides structured and secure access so your agent can perform Lmnt operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and Claude/Anthropic API Key
- Primary know-how of Claude Agents SDK
- A Lmnt account
- Some knowledge of Python

### 1. Getting API Keys for Claude/Anthropic and Composio

Claude/Anthropic API Key
- Go to the [Anthropic Console](https://console.anthropic.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Lmnt MCP?

With a standalone Lmnt MCP server, the agents and LLMs can only access a fixed set of Lmnt tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Lmnt and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Agent SDK?

Yes, you can. Claude Agent SDK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Lmnt tools.

### Can I manage the permissions and scopes for Lmnt while using Tool Router?

Yes, absolutely. You can configure which Lmnt scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Lmnt data and credentials are handled as safely as possible.
