FunASR MCP Server

Model Context Protocol server that gives AI assistants the ability to transcribe audio.

Setup

1. Install dependencies

pip install funasr

2. Optional: run with Docker

The Dockerfile starts the MCP server over stdio and is suitable for MCP directory checks that initialize the server and call tools/list.

docker build -t funasr-mcp examples/mcp_server
docker run --rm -i \
  -e FUNASR_DEVICE=cpu \
  -v /path/to/audio:/audio:ro \
  funasr-mcp

When submitting this server to MCP directories such as Glama, use this folder as the Docker build context so the container entrypoint runs funasr_mcp.py. The glama.json file in this directory declares the MCP server command and metadata for directory scanners.

Official MCP Registry checklist

The Dockerfile includes the OCI ownership label expected by the official MCP Registry:

LABEL io.modelcontextprotocol.server.name="io.github.modelscope/funasr-mcp"

Before publishing, push a public OCI image (for example to GHCR) and create a matching server.json whose name is io.github.modelscope/funasr-mcp and whose package identifier points at that image tag. The Registry verifies that the Docker/OCI label and server.json name match.

Glama submission checklist

Use these values when adding the server at https://glama.ai/mcp/servers:

Field	Value
Repository URL	https://github.com/modelscope/FunASR
Docker build context	examples/mcp_server
Dockerfile path	examples/mcp_server/Dockerfile
Server command	python /app/funasr_mcp.py
Expected MCP tool	transcribe_audio

After Glama finishes evaluation, verify that the score badge endpoint returns success before adding it to directory PRs:

[![modelscope/FunASR MCP server](https://glama.ai/mcp/servers/modelscope/FunASR/badges/score.svg)](https://glama.ai/mcp/servers/modelscope/FunASR)

If the badge endpoint still returns 404, keep the badge out of external directory submissions until the Glama listing is live.

Directory listings

The FunASR MCP server is listed on mcp.so:

Tools

transcribe_audio

Transcribe a speech audio file to text.

Parameters:

Name	Type	Required	Description
audio_path	string	Yes	Path to audio file (wav, mp3, flac, m4a, ogg)
language	string	No	Language hint (auto-detected by default)

Returns: Transcribed text with timestamps and speaker labels (when available).

Example Usage

Once configured, ask your AI assistant:

• "Transcribe the meeting recording at ~/Downloads/meeting.wav"
• "What was said in this audio file? /path/to/interview.mp3"
• "Convert this voice memo to text: ~/voice_note.m4a"

Environment Variables

Variable	Default	Description
FUNASR_DEVICE	cpu	Device: cuda, cpu, or mps
FUNASR_MODEL	iic/SenseVoiceSmall	ASR model to use

Features

• 50+ languages with automatic detection
• Speaker diarization — identifies who said what
• Timestamps — per-segment timing
• 170x realtime on GPU, 17x on CPU
• No API key needed — fully local inference
• MIT licensed, privacy-friendly (audio never leaves your machine)
