# LMNT — how to use (mcp.ai)

Connect your LMNT account and use 8 tools for artificial intelligence straight from your AI agent. Connect with your own API key. LMNT focuses on voice and audio manipulation, possibly leveraging AI to generate or transform sound for various creative and technical use cases.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_lmnt?ms=1787295960000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `lmnt_create_voice`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/lmnt`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
Discover endpoints: `GET https://api.mcp.ai/api/lmnt/_endpoints`
