Kernel Build MCP Server

Local setup required. This server has to be cloned and prepared on your machine before you register it in Claude Code.
1

Set the server up locally

Run this once to clone and prepare the server before adding it to Claude Code.

Run in terminal
git clone https://github.com/arttttt/kernel-build-mcp
cd kernel-build-mcp

Then follow the repository README for any remaining dependency or build steps before continuing.

2

Register it in Claude Code

After the local setup is done, run this command to point Claude Code at the built server.

Run in terminal
claude mcp add kernel-build -- node "<FULL_PATH_TO_KERNEL_BUILD_MCP>/dist/index.js"

Replace <FULL_PATH_TO_KERNEL_BUILD_MCP>/dist/index.js with the actual folder you prepared in step 1.

MCP server for remote Linux kernel cross-compilation.

kernel-build-mcp

MCP server for remote Linux kernel cross-compilation.

Setup

1. Install Tailscale

Install on both Mac and Linux:

# Mac
brew install tailscale

# Linux
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up

Enable Tailscale SSH on the Linux machine:

sudo tailscale up --ssh

Verify connectivity from Mac:

# Check Tailscale IP
tailscale ip -4   # on Linux machine

# Test SSH (no keys needed — Tailscale handles auth)
ssh user@100.x.x.x

Add to ~/.ssh/config for convenience:

Host kernel-build
    HostName 100.x.x.x
    User <user>

2. Deploy MCP server to Linux

scp -r . kernel-build:~/kernel-build-mcp/
ssh kernel-build "~/kernel-build-mcp/install.sh"

3. Configure

Either edit config on Linux directly:

ssh kernel-build "vi ~/.config/kernel-build-mcp/config.json"

Or use the set_config tool from Claude Code after connecting.

4. Connect from Claude Code

Copy .mcp.json to your kernel project:

cp .mcp.json /path/to/SmokeR24.1-kernel/.mcp.json

Or merge with existing .mcp.json if one exists.

Verify: claude --mcp-debug

Try it

→Perform a full kernel build using the current configuration.
→Fetch the latest changes from the remote repository and reset the state.
→Build the specific module located in the drivers/net directory.
→Retrieve the last build log to check for compilation errors.
→Download the compiled kernel artifact as a base64 encoded file.
