Architecture

This MCP server uses CC Switch's actual core library (cc_switch_lib) compiled without Tauri GUI support:

┌─────────────────────┐
│   MCP Protocol      │
│   (JSON-RPC 2.0)    │
└─────────┬───────────┘
          │
┌─────────▼───────────┐
│   cc-switch-mcp     │
│   (This Server)     │
└─────────┬───────────┘
          │
┌─────────▼───────────┐
│   cc_switch_lib     │
│   (Core Library)    │
│  - ProviderService  │
│  - Database         │
│  - Config Sync      │
└─────────────────────┘

This ensures identical behavior with the CC Switch desktop app.

Database

The server reads directly from the CC Switch SQLite database:

• Location: ~/.cc-switch/cc-switch.db
• Compatible: Fully compatible with the desktop app
• Safe: Can be used alongside CC Switch desktop
