## MCP Servers

| Server | Description |
|--------|-------------|
| `context7` | Framework documentation lookup via Context7 |

### Context7

**Tools provided:**
- `resolve-library-id` - Find library ID for a framework/package
- `get-library-docs` - Get documentation for a specific library

Supports 100+ frameworks including Rails, React, Next.js, Vue, Django, Laravel, and more.

MCP servers start automatically when the plugin is enabled.

**Authentication:** To avoid anonymous rate limits, set the `CONTEXT7_API_KEY` environment variable with your Context7 API key. The plugin passes this automatically via the `x-api-key` header. Without it, requests go unauthenticated and will quickly hit the anonymous quota limit.

## Browser Automation

This plugin uses **agent-browser CLI** for browser automation tasks. Install it globally:

```bash
npm install -g agent-browser
agent-browser install  # Downloads Chromium
```

The `agent-browser` skill provides comprehensive documentation on usage.

## Installation

```bash
claude /plugin install compound-engineering
```

## Known Issues

### MCP Servers Not Auto-Loading

**Issue:** The bundled Context7 MCP server may not load automatically when the plugin is installed.

**Workaround:** Manually add it to your project's `.claude/settings.json`:

```json
{
  "mcpServers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp",
      "headers": {
        "x-api-key": "${CONTEXT7_API_KEY:-}"
      }
    }
  }
}
```

Set `CONTEXT7_API_KEY` in your environment to authenticate. Or add it globally in `~/.claude/settings.json` for all projects.
