ToughTongue AI MCP Server

Agent skills and MCP server for Tough Tongue AI, the platform for handling tough conversations. Some, the AI takes: voice agents that answer and place calls, qualify leads, run demos, screen candidates, and book meetings. Others, you nail: hyper-realistic roleplay that gets you ready for negotiations, interviews, and coaching conversations. It is available as a remote MCP endpoint.

Teams that work with agent skills, codex and sales training and want a hosted endpoint instead of running a local process. The project is written in JavaScript.
