Toughtongue Skills MCP Server

Tough Tongue AI Skills

Tough Tongue AI is the platform for tough conversations. Some the AI takes: voice agents that call, demo, screen, and book. Others you nail: realistic roleplay for negotiations, interviews, and coaching. This plugin lets your coding agent build, run, and improve both, in your personal or organization workspace.

Armed with these skills, your coding agent becomes a workspace commander for your Tough Tongue AI voice agents.

Get started

1. Install

Coding agents

These get the skills and the MCP server together.

Any coding agent (Claude Code, Cursor, Codex, Copilot CLI, VS Code)

npx plugins add tough-tongue/toughtongue-skills

Claude Code

/plugin marketplace add tough-tongue/toughtongue-skills
/plugin install toughtongue@toughtongue-skills

Codex

codex plugin marketplace add tough-tongue/toughtongue-skills
codex plugin add toughtongue@toughtongue

Cursor

Settings > Plugins > Team Marketplaces > Add Marketplace > Import from Repo, enter https://github.com/tough-tongue/toughtongue-skills, then install toughtongue.

Windsurf, Gemini CLI, and other coding agents

npx skills add tough-tongue/toughtongue-skills

Then add a remote (HTTP) MCP server with the URL https://api.toughtongueai.com/api/public/mcp. Config snippets: clients.md.

Web agents

These connect to the MCP server directly.

claude.ai and Claude Desktop

Settings > Connectors > Add custom connector. Name it Tough Tongue AI, paste https://api.toughtongueai.com/api/public/mcp, and approve the sign-in.

ChatGPT

Settings > Apps, find Tough Tongue AI in the app directory, and connect.

2. Sign in

Restart your agent. The first Tough Tongue AI action opens a browser sign-in; approve it once. No API key needed. (No browser, e.g. CI? Use an API key, a personal access token from the developer portal: see clients.md.)

3. Ask

Get me started with Tough Tongue AI.

Then try:

• "Create a practice scenario for an enterprise pricing negotiation."
• "For the Enterprise Discovery Call scenario, pull the last 50 sessions. What are the top 5 improvement areas?"
• "The onboarding agent keeps ending calls too early. Find out why and refine it."

Skills

• ttai-agent: create, edit, and refine Scenarios; workspaces, calls, meeting bots, and sharing.
• ttai-session-analyst: turn session scores and transcripts into team and coaching reports.
• ttai-browser-demo-builder: script browser steps for product demos from a recording or a walkthrough.
• ttai-agent-apps: build Agent Desktop apps, such as a board or checklist the voice agent updates during a call.

Your agent picks the right skill on its own. In Claude Code you can also call one directly, for example /toughtongue:ttai-agent.

What you can do

• Practice a lost deal. "Pull the last 3 calls from Gong where we lost on pricing and create a scenario to practice that objection."
• See how the team is doing. "Top 5 improvement areas from the last 50 Enterprise Discovery Call sessions, as a 3-slide deck."
• Improve an agent from real calls. "Find what went wrong in the 5 lowest-scoring onboarding sessions and refine the scenario."
• Prep for a meeting. "I meet Sarah Chen from Acme in 30 minutes. Create a quick practice scenario."
• Score real calls automatically. "Every time a call ends in Gong, score the transcript and email the rep a coaching report."

Update

Claude Code

claude plugin marketplace update toughtongue-skills
claude plugin update toughtongue@toughtongue-skills

Codex

codex plugin marketplace upgrade toughtongue
codex plugin add toughtongue@toughtongue

npx plugins add and Cursor's import always install the latest version.

Troubleshooting

• Sign-in or 401 errors: finish the browser sign-in. Claude Code: /mcp. Codex: codex mcp login ttai. Cursor: Settings > MCP.
• A Tough Tongue AI tool is missing: start a new chat; if it persists, remove and re-add the MCP server.
• The agent explains but can't act: the skills are installed but the MCP server is not. Add it for your client (clients.md).
• A Scenario change doesn't show in a running call: edits apply to new sessions.
