Linkr KVM MCP Server

Linkr KVM MCP Server exposes Radxa Linkr KVM controls through the Model Context Protocol (MCP). It lets an MCP client capture screenshots, crop screen areas, send keyboard and mouse events, type text, wait for on-screen text, and ask vision/OCR models about the current screen.

Requirements

• Python 3.11 or newer is recommended.

• A reachable Radxa Linkr KVM device.

• A Linkr API key.

• Vision/OCR provider API keys if using ask_vl or ocr_area.

Installation

Create and activate a virtual environment, then install dependencies:

python -m venv .venv
.\.venv\Scripts\Activate.ps1
pip install -r requirements.txt

On POSIX-like shells:

python3 -m venv .venv
. .venv/bin/activate
pip install -r requirements.txt

Configuration

Copy the example configuration and fill in real credentials:

cp config.example.yaml config.yaml

Do not commit real secrets. Keep config.example.yaml sanitized.

Running

Recommended direct launch:

python main.py

The default transport is stdio. You can also select a transport explicitly:

python main.py --transport stdio
python main.py --http --host 127.0.0.1 --port 8000 --path /mcp
python main.py --transport sse --host 127.0.0.1 --port 8000 --sse-path /sse --message-path /messages/

Environment variables can also set defaults:

• MCP_TRANSPORT

• MCP_HOST

• MCP_PORT

• MCP_PATH

• MCP_SSE_PATH

• MCP_MESSAGE_PATH

The helper scripts forward arguments to the Python launcher:

.\start.ps1 --http

start.bat --transport stdio

./start.sh --http
