FunASR MCP server

FunASR MCP Server

Model Context Protocol server that gives AI assistants local audio transcription with SenseVoiceSmall by default.

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 \
  --mount type=bind,src=/path/to/audio,dst=/audio,readonly \
  --mount type=volume,src=funasr-mcp-cache,dst=/root/.cache/modelscope \
  funasr-mcp

Verify the image entrypoint and MCP handshake without downloading a model:

python examples/mcp_server/smoke_test.py 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 repository root glama.json declares GitHub maintainer ownership for Glama, while the glama.json file in this directory declares the container command and metadata for directory scanners.

Official MCP Registry

The versioned Registry metadata is in server.json. It points to the public GHCR image and asks clients to mount one host audio directory at /audio read-only. The Dockerfile carries the matching OCI ownership label:

Current published release:

• GitHub release mcp-v0.1.2
• Official MCP Registry entry
• Public GHCR package

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

The release workflow validates the metadata against the official schema, builds the image, performs an MCP initialize and tools/list handshake, pushes the versioned image to GHCR, and publishes server.json through the official mcp-publisher CLI.

To release a new MCP server version:

1. Update version and the OCI image tag in server.json together.
2. Merge the change after the MCP validation workflow passes.
3. Have a modelscope organization Owner push the matching mcp-v<version> tag, for example mcp-v0.1.2.
4. Approve the protected mcp-registry-publish environment deployment.

The official Registry only grants the io.github.modelscope/* namespace to a GitHub organization Owner. Keep the publish environment restricted to release tags and require a maintainer approval because its OIDC token can publish the organization namespace.

After publication, clients can run the pinned image directly:

docker run --rm -i \
  --mount type=bind,src=/path/to/audio,dst=/audio,readonly \
  --mount type=volume,src=funasr-mcp-cache,dst=/root/.cache/modelscope \
  ghcr.io/modelscope/funasr-mcp:0.1.2

When using the container, pass tool paths under /audio, such as /audio/meeting.wav.

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 listing or API shows an evaluated quality score before adding it to directory PRs. An HTTP 200 from the listing or badge endpoint alone does not prove that a score has been assigned:

[![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 published in the official Registry and listed on mcp.so:

• https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.modelscope/funasr-mcp

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	auto, zh, yue, en, ja, or ko (default: auto)

Returns: Transcribed text with per-segment timestamps when the model returns them.

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	Model name or local model path passed to AutoModel

Features

• Five-language transcription — Mandarin, Cantonese, English, Japanese, and Korean
• Automatic detection or explicit hints — auto, zh, yue, en, ja, and ko
• VAD segmentation — splits longer audio before recognition
• Optional segment timestamps — included only when the configured model returns them
• Configurable local inference — choose the model and CPU, CUDA, or MPS with environment variables
• No API key needed — fully local inference
• MIT licensed, privacy-friendly (audio never leaves your machine)
