VLC MCP Server

An MCP (Model Context Protocol) Server to play and control movies using the VLC media player. Use any MCP client to control play videos remotely (e.g. awesome-mcp-clients)

I use my signal-mcp-client running on an old laptop connected to my beamer. This way I can play a movie by sending a signal message. An example of how to use it is shown in the screenshot below.

Usage

This installation is for Linux systems running Ubuntu or a similar Debian-based system like Raspberry Pi OS. With a few modifications it should also work on other systems. Feel free to create a pull request if you get it working on another system.

1. Install VLC, mediainfo and uv.

   sudo apt-get install vlc mediainfo
   curl -LsSf https://astral.sh/uv/install.sh | sh
   

2. Start the VLC http server:

   export DISPLAY=:0 # needed when running it remotely on a server
   vlc --extraintf=http --http-host=localhost --http-port=8081 --http-password=your_password
   

3. Add the server to the MCP config file of your client (like signal-mcp-client or awesome-mcp-clients)

   {
       "name": "vlc-mcp-server",
       "command": "uvx",
       "args": [
           "vlc-mcp-server"
       ],
       "env": {
           "ROOT_VIDEO_FOLDER": "path/to/your/video/folder",
           "VLC_HTTP_HOST": "localhost",
           "VLC_HTTP_PORT": "8081",
           "VLC_HTTP_PASSWORD": "your_password"
       }
   }
   

   or clone the repo and use uv with a directory:

   {
       "name": "vlc-mcp-server",
       "command": "uv",
       "args": [
           "--directory",
           "path/to/root/dir/",
           "run",
           "vlc_mcp_player/main.py"
       ],
       "env": {
           "the same as above"
       }
   }

Contributions to this project are welcome. Feel free to report bugs, suggest ideas, or create merge requests.

Development

Clone repo and install dependencies:

git clone https://github.com/piebro/vlc-mcp-server.git
uv venv
uv sync --extra dev
uv run pre-commit install

Testing

Use mcp-client-for-testing to test the tools of the server using the json config using the local path.

uvx mcp-client-for-testing \
    --config '
    [
        "the json config from above"
    ]
    ' \
    --client_log_level "INFO" \
	--server_log_level "INFO" \
    --tool_call '{"name": "show_video", "arguments": {"video_title": "David Lynch - Dune", "subtitle_language_code": "en"}}'

Formatting and Linting

The code is formatted and linted with ruff:

uv run ruff format
uv run ruff check --fix

Building with uv

Build the package using uv:

uv build

Releasing a New Version

To release a new version of the package to PyPI, create and push a new Git tag:

1. Checkout the main branch and get the current version:

   git checkout main
   git pull origin main
   git describe --tags
   

2. Create and push a new Git tag:

   git tag v0.2.0
   git push origin v0.2.0
   

The GitHub Actions workflow will automatically build and publish the package to PyPI when a new tag is pushed. The python package version number will be derived directly from the Git tag.

Running as a Systemd Service

To ensure the VLC HTTP interface runs automatically on boot and restarts if it fails (on Linux systems), you can set it up as a systemd user service. User services run under your specific user account.

This setup assumes that you have completed the setup steps.

1. Enable User Lingering to keep your user session active after logging out.

   sudo loginctl enable-linger $USER
   

2. Create Systemd Service Directory

   mkdir -p /home/$USER/.config/systemd/user/
   

3. Create Service File for VLC HTTP Server. Make sure vlc is installed using apt and not using snap or change the path to the vlc binary.

   cat << EOF > "/home/$USER/.config/systemd/user/vlc-http.service"
   [Unit]
   Description=VLC Media Player with HTTP Interface
   After=network.target sound.target
   
   [Service]
   Restart=on-failure
   RestartSec=30
   SyslogIdentifier=vlc-http
   Environment="DISPLAY=:0"
   
   ExecStart=/usr/bin/vlc --extraintf=http --http-host=localhost --http-port=8081 --http-password=your_password
   
   ExecStop=/usr/bin/pkill -f '/usr/bin/vlc --extraintf=http --http-host=localhost --http-port=8080'
   
   [Install]
   WantedBy=default.target
   EOF
   

4. Enable and Start the Services

   systemctl --user daemon-reload
   systemctl --user enable vlc-http.service
   systemctl --user start vlc-http.service
   

5. Check Service Status and Logs

   systemctl --user status vlc-http.service
   journalctl --user -u vlc-http.service -f
