RustDeskMCP fork

This repository is a modified fork of the official RustDesk project and remains licensed under AGPL-3.0. It adds an embedded localhost MCP server, a separate RustDeskMCP app identity, and agent-oriented desktop and terminal control flows on top of the upstream RustDesk codebase.

Chinese version of this fork overview: docs/README-ZH.md

What this fork adds

• an embedded localhost MCP server inside the desktop Flutter client
• a separate Windows runtime identity, RustDeskMCP, so this fork does not collide with a normal RustDesk installation
• MCP desktop-session operations that follow the normal RustDesk connection path
• MCP terminal-session operations
• explicit local input lock and unlock semantics for agent-driven desktop tasks
• remote desktop frame capture for vision-based automation

Design rules of this fork

• Keep the normal non-MCP RustDesk user path working.
• Enable MCP from the GUI, not from a separate startup mode.
• Make MCP operations follow the same user-visible session flow as RustDesk.
• Keep the current MCP surface scoped to desktop and terminal sessions.

MCP quick start

1. Start RustDeskMCP.
2. In the GUI, enable Settings -> Security -> Enable MCP server.
3. Send JSON-RPC requests to http://127.0.0.1:59940/mcp.
4. Use initialize, then tools/list, then tools/call.

Current MCP scope

Desktop session tools:

• open_desktop_session
• input_password
• select_desktop_display
• get_desktop_frame
• lock_remote_user_input
• unlock_remote_user_input
• mouse_move
• mouse_click
• keyboard_input
• keyboard_hotkey

Terminal session tools:

• open_terminal_session
• input_password
• terminal_input
• terminal_output

Dependencies

Desktop versions use Flutter or Sciter (deprecated) for GUI, this tutorial is for Sciter only, since it is easier and more friendly to start. Check out our CI for building Flutter version.

Please download Sciter dynamic library yourself.

Raw Steps to build

• Prepare your Rust development env and C++ build env

• Install vcpkg, and set VCPKG_ROOT env variable correctly

  • Windows: vcpkg install libvpx:x64-windows-static libyuv:x64-windows-static opus:x64-windows-static aom:x64-windows-static
  • Linux/macOS: vcpkg install libvpx libyuv opus aom

• run cargo run

How to build with Docker

Begin by cloning the repository and building the Docker container:

git clone https://github.com/rustdesk/rustdesk
cd rustdesk
git submodule update --init --recursive
docker build -t "rustdesk-builder" .

Then, each time you need to build the application, run the following command:

docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder

Note that the first build may take longer before dependencies are cached, subsequent builds will be faster. Additionally, if you need to specify different arguments to the build command, you may do so at the end of the command in the <OPTIONAL-ARGS> position. For instance, if you wanted to build an optimized release version, you would run the command above followed by --release. The resulting executable will be available in the target folder on your system, and can be run with:

target/debug/rustdesk

Or, if you're running a release executable:

target/release/rustdesk

Please ensure that you run these commands from the root of the RustDesk repository, or the application may not find the required resources. Also note that other cargo subcommands such as install or run are not currently supported via this method as they would install or run the program inside the container instead of the host.
