Which integrations are available for this server?

Supports remote Git repository management within the kernel source tree, including fetching updates and performing hard resets to match remote states. Enables remote Linux kernel cross-compilation, providing tools for full kernel and module-specific builds, applying defconfigs, and retrieving build artifacts and logs.

How do I use kernel-build-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@kernel-build-mcp pull the latest changes and run a full kernel build" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

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
