Multi-engine AI assistant desktop client based on ACP (Agent Client Protocol), supporting any ACP-compatible Agent engine with cross-platform local AI Agent execution capabilities.

## Core Features

### Multi-Engine Support

NuwaClaw uses [ACP (Agent Client Protocol)](https://agentclientprotocol.com/) to communicate with Agent engines, supporting any ACP-compatible Agent:

| Engine | Description |
|--------|-------------|
| **Claude Code** | Anthropic's official CLI Agent, recommended ⭐ |
| **Codex CLI** | OpenAI's code Agent |
| **Gemini CLI** | Google's AI Agent |
| **GitHub Copilot** | GitHub's AI coding assistant |
| **Cline** | Open-source autonomous coding Agent |
| **Cursor** | Cursor IDE's Agent capability |
| **Goose** | Block's open-source AI Agent |
| **Qwen Code** | Alibaba's Qwen code Agent |
| **Junie** | JetBrains' AI Agent |
| **OpenCode** | Open-source code Agent |
| **Nuwaxcode** | Agent engine based on OpenCode |
| **More...** | [View full list](https://agentclientprotocol.com/get-started/agents) |

> **ACP Protocol**: Agent Client Protocol standardizes communication between code editors/IDEs and AI coding agents. Similar to how LSP works for language services, ACP lets you connect any ACP-compatible Agent to any supporting client.

- Isolated engine execution with independent environment configuration
- Dynamic engine switching without app restart
- Avoid vendor lock-in, choose your Agent freely

### Cross-Platform Clients
- **Electron Client** - Desktop client based on Electron + React

### MCP Protocol Support
- Dynamic MCP server management
- Multi-protocol support (stdio, SSE, Streamable HTTP)
- Resilient connection with automatic reconnection

### Other Features
- **Persistent Storage** - SQLite local storage
- **System Tray** - Background operation with quick actions

## Quick Start

### Electron Client

```bash
# Option 1: Using Makefile (recommended, run from project root)
make electron-dev     # Development mode
make electron-build   # Build
make electron-dist    # Package

# Option 2: Using npm commands in the crate directory
cd crates/agent-electron-client

# Install dependencies
npm install

# Development mode
npm run dev

# Build
npm run build

# Package
npm run dist:mac      # macOS
npm run dist:win      # Windows
npm run dist:linux    # Linux
```

### MCP Proxy Service

```bash
cd crates/nuwax-mcp-stdio-proxy

# Install dependencies
npm install

# Build
npm run build

# Run (stdio aggregation mode)
nuwax-mcp-stdio-proxy --config '{"mcpServers":{...}}'

# Run (protocol conversion mode)
nuwax-mcp-stdio-proxy convert http://remote-mcp-server/sse

# Run (persistent bridge mode)
nuwax-mcp-stdio-proxy proxy --port 18099 --config '{"mcpServers":{...}}'
```

### IPC Channels

| Category | Channels |
|----------|----------|
| Session | `session:list`, `session:create`, `session:delete` |
| Message | `message:list`, `message:add` |
| Settings | `settings:get`, `settings:set` |
| Agent | `agent:init`, `agent:destroy`, `agent:prompt` |
| MCP | `mcp:install`, `mcp:uninstall`, `mcp:start`, `mcp:stop` |

## MCP Proxy Service Details

`nuwax-mcp-stdio-proxy` is an MCP protocol aggregation proxy that solves lifecycle management issues when integrating multiple MCP servers.

### Running Modes

| Mode | Purpose | Command |
|------|---------|---------|
| **stdio** | Aggregate multiple MCP servers into single stdio interface | `nuwax-mcp-stdio-proxy --config '...'` |
| **convert** | Convert remote MCP service to local stdio | `nuwax-mcp-stdio-proxy convert <url>` |
| **proxy** | Persistent bridge, pre-start and expose HTTP interface | `nuwax-mcp-stdio-proxy proxy --port 18099` |

### Core Features
- **Readiness Detection**: Block until MCP servers are ready
- **Resilient Transport**: Heartbeat detection, exponential backoff reconnection, request queue
- **Centralized Cleanup**: Gracefully terminate all child processes

### Resilient Transport Parameters

| Parameter | Default | Description |
|-----------|---------|-------------|
| `pingIntervalMs` | 20000 | Heartbeat interval |
| `maxConsecutiveFailures` | 3 | Consecutive failure threshold |
| `maxReconnectDelayMs` | 60000 | Reconnection delay cap |
| `maxQueueSize` | 100 | Request queue capacity |

## Configuration

### Electron Client Configuration

Configure through setup wizard on first run:
1. Enter Anthropic API Key
2. Select default model
3. Configure MCP servers

Sensitive configuration is stored in SQLite database, not hardcoded.

### MCP Server Configuration Example

```json
{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/dir"]
    },
    "github": {
      "url": "https://api.github.com/mcp"
    }
  }
}
```
