About ToughTongue AI

ToughTongue AI connects coding agents to a workspace for building and improving voice agents and roleplay scenarios. Its skills cover scenario authoring, session analysis, demos, and agent apps.

Key features

  1. 01Create and refine scenarios
  2. 02Analyze session scores and transcripts
  3. 03Build browser demo scripts
  4. 04Create Agent Desktop apps

Use cases

  1. 01Practice negotiation conversations
  2. 02Find coaching themes in call sessions
  3. 03Improve agents using low-scoring sessions
  4. 04Prepare for an upcoming meeting

MCP support

The plugin connects to Tough Tongue AI’s hosted MCP server over HTTPS, with browser-based OAuth sign-in. The server lets coding agents work with scenarios, voice agents, roleplays, and their sessions in the user’s workspace.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

Run commands in a terminal; paste JSON into the client’s MCP config and restart. Servers that need sign-in will prompt on first connect.

Tough Tongue AI Skills

MCP Registry

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.

How it works

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

What the plugin contains and connects to
  • Skills and configuration only. Markdown skills, reference docs, an icon, and MCP server configs. No hooks, scripts, or executable code.
  • One server. Your agent talks to Tough Tongue AI's hosted MCP server at https://api.toughtongueai.com/api/public/mcp over HTTPS. You sign in with OAuth in your browser. The plugin reads no API keys, tokens, or environment variables, and its configs carry only that URL.
  • What is sent. Only what your agent passes to the ttai tools: Scenario text, session queries, and the phone numbers, meeting links, transcripts, or recording links you ask it to use. It all stays in your Tough Tongue AI workspace under the privacy policy.

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. Claude Code over SSH: run claude mcp login plugin:toughtongue:ttai --no-browser in an ssh -t session and open the printed URL on your own machine. Running in CI or on a server with no browser? See headless setup in the Tough Tongue AI docs.

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 (over SSH: claude mcp login plugin:toughtongue:ttai --no-browser, connected with ssh -t). 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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
