Common questions

Is Voice Transcriber MCP Server safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: GROQ_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 8 months ago, and the latest version (2.0.1) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Voice Transcriber MCP Server

MCP server that automatically transcribes Google Chat voice messages using Groq Whisper API (whisper-large-v3). No local GPU needed.

When Claude Code encounters an audio attachment in a Google Chat message, this server transcribes it immediately without asking for confirmation.

Features

  • Transcribe Google Chat voice messages by URL (automatic)
  • Transcribe local audio files (mp3, m4a, wav, ogg, flac, webm, aac)
  • Uses Groq Whisper API (free tier, fast, cloud-based)
  • Reuses Google Chat OAuth2 credentials (no separate Google auth needed)

Prerequisites

1. Groq API Key (free)
  1. Go to console.groq.com/keys
  2. Create a free account
  3. Generate an API key
  4. You'll set this as GROQ_API_KEY in your MCP config (see below)
2. Google Chat OAuth2 Token

This server needs a valid Google Chat OAuth2 token (token.json) to fetch messages and download audio attachments.

If you already use a Google Chat MCP server (e.g. multi-chat-mcp-server), the token is already available. Default path:

~/tools/multi-chat-mcp-server/src/providers/google_chat/token.json

If your token is in a different location, set the GCHAT_TOKEN_PATH environment variable.

If you don't have a Google Chat token yet, you need to:

  1. Create a Google Cloud project with Chat API enabled
  2. Create OAuth2 credentials (Desktop app)
  3. Run the OAuth flow to generate token.json with scopes:
  • https://www.googleapis.com/auth/chat.messages.readonly
  • https://www.googleapis.com/auth/chat.spaces.readonly
3. uv (Python package manager)
OSCommand
Linux / macOS / WSL`curl -LsSf https://astral.sh/uv/install.sh \sh`
Windows`powershell -c "irm https://astral.sh/uv/install.ps1 \iex"`

Verify: uv --version

Installation

git clone https://github.com/fgasparetto/voice-transcriber-mcp.git

cd voice-transcriber-mcp uv sync

Configuration

Add to your Claude Code MCP config (.mcp.json or ~/.claude.json):

{

"mcpServers": { "voice-transcriber": { "type": "stdio", "command": "uv", "args": [ "--directory", "/path/to/voice-transcriber-mcp", "run", "python", "server.py" ], "env": { "GROQ_API_KEY": "gsk_your_groq_api_key_here" } } } }

Replace:

  • /path/to/voice-transcriber-mcp with the actual clone directory
  • gsk_your_groq_api_key_here with your Groq API key
Environment Variables
VariableRequiredDefaultDescription
GROQ_API_KEYYes—Groq API key (get one free)
GCHAT_TOKEN_PATHNo~/tools/multi-chat-mcp-server/src/providers/google_chat/token.jsonPath to Google Chat OAuth2 token

Tools

transcribe_voice_message

Transcribe a voice message from Google Chat. Called automatically by Claude when it encounters an audio attachment.

transcribe_voice_message(

message_url="https://chat.google.com/dm/SPACE/THREAD/MSG", language="it" )

transcribe_audio_file

Transcribe a local audio file.

transcribe_audio_file(

file_path="/tmp/recording.m4a", language="it" )

Platform Notes

Linux

No additional steps. Ensure uv is in your PATH.

macOS
  • If uv not found after install: export PATH="$HOME/.local/bin:$PATH"
Windows (WSL)

Claude Code runs inside WSL. All paths must be Linux-style:

  • Token path: /home/USER/tools/... (NOT /mnt/c/...)
  • If uv not found: source ~/.bashrc or add ~/.local/bin to PATH

Troubleshooting

ProblemSolution
GROQ_API_KEY not setAdd it to the env section in your MCP config
Google Chat token not foundSet GCHAT_TOKEN_PATH or authenticate your Google Chat MCP
Groq API error 413Audio file too large (Groq limit: 25MB)
uv: command not foundInstall uv (see Prerequisites)

How It Works

Claude Code → MCP tool call → server.py
  1. Parse Google Chat URL
  2. Fetch message via Google Chat API (OAuth2 token)
  3. Download audio attachment via media API
  4. Send to Groq Whisper API (whisper-large-v3)
  5. Return transcribed text
