Voice Call

Local, MCP-driven voice conversations between coding agents and you.

Install · Take a call · MCP · Reference

Agents use Model Context Protocol (MCP) to start calls with a briefing and questions, query call status, and retrieve transcripts and file activity. Answer on your desktop to discuss decisions with an OpenAI Realtime voice assistant. The voice assistant can query project files through read-only tools, and the calling agent receives the conversation when the call ends.

Features

• Answer, reject, and end calls from a desktop window.

• Discuss project files through read-only search and file tools.

• Review the transcript and file activity after a call.

Install

Ubuntu 24.04+ on x86_64, with a desktop session, microphone, and speakers. Node.js and Electron are bundled. Answered calls require an OpenAI API key with billing and Realtime access; usage is billed separately from ChatGPT subscriptions.

Keep ~/.local/bin on your PATH. If the doctor reports "No usable sandbox", run voice-call setup-sandbox and repeat the check. Sandbox setup uses sudo to install a directory-scoped AppArmor exception; anyone who can replace a matching executable inherits it. See installation, updates, and sandbox details.

Take a call

1. Connect your agent through MCP and ask it to call you with a self-contained briefing.

2. Choose Answer to talk or Reject to decline.

3. Choose Hang up to return the transcript and keep the review window open, or say goodbye to end the call and close the app.

The voice assistant can inspect files but cannot execute commands or change them.

Connect an agent

Configure your MCP client to run voice-call mcp over stdio, with OPENAI_API_KEY in its launch environment:

{
  "command": "voice-call",
  "args": ["mcp"]
}

The MCP process needs access to your desktop and audio session. Set its tool execution timeout above the requested call duration; calls default to 15 minutes. See OpenCode configuration, voice selection, and session-relative file access.

Privacy and scope

Briefings, audio, and requested file contents go to OpenAI. Grant access only to project directories you permit the voice assistant to read, and keep secrets outside that root. Transcripts and file activity live in memory and are lost when MCP restarts. See file boundaries and call limits.
