Relay server for [msclaude](https://msclaude.ai) — use Claude Code from any browser.

msclaude lets you run Claude Code on your local machine and access it through a web interface. The server acts as an encrypted WebSocket relay between your browser and the local agent. No data is stored on the server.

## Install

```bash
npm install -g @agent-link/server
```

## Usage

```bash
# Start server (foreground)
agentlink-server start --port 3456

# Start server (background)
agentlink-server start --daemon --port 3456

# Stop server
agentlink-server stop

# Check status
agentlink-server status

# Upgrade to latest version
agentlink-server upgrade

# Auto-start on boot
agentlink-server service install --port 3456
agentlink-server service uninstall
```

## Public file downloads

Set `AGENTLINK_FILES_DIR` to expose an unauthenticated `/files/*` download path
from a directory outside the web build output:

```bash
AGENTLINK_FILES_DIR=/home/shikailun/agentlink-files agentlink-server start --port 3456
```

For example, `/home/shikailun/agentlink-files/tool.zip` is served at
`/files/tool.zip`. Directory indexes and dotfiles are disabled.

## How it works

```
Browser ↔ msclaude Server ↔ msclaude Client ↔ Claude Code
  (web)      (relay)                (your machine)         (CLI)
```

The server is a lightweight Express + WebSocket relay. It serves the web UI, assigns unique session URLs, and forwards encrypted messages between the browser and the agent.
