Whisper MCP Server

A lightweight MCP (Model Context Protocol) server for local audio transcription using whisper.cpp. There are several Whisper MCP implementations out there. This one is minimal and pairs with apple-voice-memo-mcp for a complete voice memo workflow.

Features

  • Local transcription - All processing happens on your machine
  • Multiple models - Choose from tiny, base, small, medium, or large models
  • Various formats - Supports wav, mp3, m4a, and other audio formats
  • Timestamps - Get transcriptions with or without timestamps

Requirements

  • macOS (tested on Apple Silicon)
  • Node.js 18+
  • whisper-cpp: brew install whisper-cpp
  • ffmpeg: brew install ffmpeg

Installation

Terminal
npm install -g whisper-mcp

Or run directly:

Terminal
npx whisper-mcp

Configuration

Claude Desktop

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

config.json
{
  "mcpServers": {
    "whisper-mcp": {
      "command": "npx",
      "args": ["-y", "whisper-mcp"]
    }
  }
}

After editing, restart Claude Desktop.

Claude Code (CLI)

For Claude Code, add to your project's .mcp.json file:

config.json
{
  "mcpServers": {
    "whisper-mcp": {
      "command": "npx",
      "args": ["-y", "whisper-mcp"]
    }
  }
}

Or for user-wide configuration, add to ~/.claude/settings.json:

config.json
{
  "mcpServers": {
    "whisper-mcp": {
      "command": "npx",
      "args": ["-y", "whisper-mcp"]
    }
  }
}

Tip: Use /mcp in Claude Code to verify the server is connected.

Local Development Setup

If running from source instead of npm:

config.json
{
  "mcpServers": {
    "whisper-mcp": {
      "command": "node",
      "args": ["/path/to/whisper-mcp/dist/index.js"]
    }
  }
}

With Apple Voice Memos MCP

For a complete voice memo workflow, use alongside apple-voice-memo-mcp:

config.json
{
  "mcpServers": {
    "apple-voice-memo-mcp": {
      "command": "npx",
      "args": ["-y", "apple-voice-memo-mcp"]
    },
    "whisper-mcp": {
      "command": "npx",
      "args": ["-y", "whisper-mcp"]
    }
  }
}
