feat(websearch): add multi-tier MCP fallback for third-party profiles

Implements CCS WebSearch Native Infrastructure (Phases 1-3):

Phase 1 - Multi-tier MCP Fallback:
- Add mcp-manager.ts with ensureMcpWebSearch() for auto-configuration
- Support web-search-prime (primary), Brave Search, and Tavily MCPs
- Case-insensitive detection of existing web search MCPs
- Block-websearch hook for optional native WebSearch blocking

Phase 2 - User Configuration:
- Add WebSearchConfig interface to unified-config-types.ts
- Add getWebSearchConfig() to unified-config-loader.ts
- Support configurable webSearchPrimeUrl for security
- Add GET/PUT /api/websearch endpoints in routes.ts
- Add WebSearch settings UI in settings.tsx dashboard

Phase 3 - Documentation & Testing:
- Add WebSearch section to README.md
- Create comprehensive docs/websearch.md guide
- Add 23 unit tests for MCP manager logic

Enables web search for gemini, codex, agy, qwen, glm, kimi profiles
that cannot access Anthropic's native WebSearch API.

## WebSearch
Third-party profiles (Gemini, Codex, GLM, etc.) cannot use Anthropic's native WebSearch. CCS automatically configures MCP-based web search as a fallback.
### How It Works
| Profile Type | WebSearch Method |
|--------------|------------------|
| Claude (native) | Anthropic WebSearch API |
| OAuth providers | MCP web-search-prime (auto-configured) |
| API profiles | MCP web-search-prime (auto-configured) |
### Configuration
Configure via dashboard (**Settings** page) or `~/.ccs/config.yaml`:
```yaml
websearch:
enabled: true # Enable/disable auto-config
provider: auto # auto | web-search-prime | brave | tavily
fallback: true # Enable fallback chain
```
### Optional API Keys
For additional search providers, set environment variables:
```bash
export BRAVE_API_KEY="your-key" # Free tier: 15k queries/month
export TAVILY_API_KEY="your-key" # AI-optimized search (paid)
```
> [!NOTE]
> `web-search-prime` works without API keys. Brave/Tavily are optional fallbacks.
See [docs/websearch.md](./docs/websearch.md) for detailed configuration and troubleshooting.

# WebSearch Configuration Guide
CCS provides automatic web search capability for all profiles, including third-party providers that cannot access Anthropic's native WebSearch API.
## How WebSearch Works
### Native Claude Accounts
When using a native Claude subscription account, WebSearch is handled by Anthropic's server-side API ($10/1000 searches, usage-based billing).
### Third-Party Profiles
Third-party profiles (OAuth and API-based) cannot use Anthropic's WebSearch because:
- Claude Code CLI executes tools locally
- CLIProxyAPI only receives conversation messages
- Tool execution never reaches the third-party backend
CCS solves this by automatically configuring MCP (Model Context Protocol) web search servers.
## Architecture
```
┌──────────────────────────────────────────────────────────────┐
│ Claude Code CLI │
│ │
│ WebSearch Tool Request │
│ │ │
│ ├── Native Claude Account? → Anthropic WebSearch API │
│ │ ($10/1000 searches) │
│ │ │
│ └── Third-party Profile? → MCP Fallback Chain │
│ │ │
│ ├── 1. web-search-prime │
│ ├── 2. Brave Search (free) │
│ └── 3. Tavily (paid) │
└──────────────────────────────────────────────────────────────┘
```
## MCP Providers
| Provider | Type | Cost | API Key Required | Notes |
|----------|------|------|------------------|-------|
| web-search-prime | HTTP MCP | Free | No | Primary, always available |
| Brave Search | stdio MCP | Free tier | `BRAVE_API_KEY` | 15k queries/month |
| Tavily | stdio MCP | Paid | `TAVILY_API_KEY` | AI-optimized search |
## Configuration
### Via Dashboard
1. Open dashboard: `ccs config`
2. Navigate to **Settings** page
3. Configure WebSearch options:
- **Enable/Disable**: Toggle auto-configuration
- **Provider**: Choose preferred provider
- **Fallback**: Enable/disable fallback chain
### Via Config File
Edit `~/.ccs/config.yaml`:
```yaml
websearch:
enabled: true # Enable auto-config (default: true)
provider: auto # auto | web-search-prime | brave | tavily
fallback: true # Enable fallback chain (default: true)
webSearchPrimeUrl: "https://..." # Optional: custom endpoint
```
### Provider Options
- **auto** (default): Uses web-search-prime, adds Brave/Tavily if API keys available
- **web-search-prime**: Free, no API key needed
- **brave**: Requires `BRAVE_API_KEY` env var
- **tavily**: Requires `TAVILY_API_KEY` env var
## Setting Up Optional Providers
### Brave Search (Free Tier)
1. Get API key: [brave.com/search/api](https://brave.com/search/api)
2. Set environment variable:
```bash
export BRAVE_API_KEY="your-api-key"
```
3. Restart CCS - Brave will be added to fallback chain
**Free tier limits**: 15,000 queries/month, 1 query/second
### Tavily (AI-Optimized)
1. Get API key: [tavily.com](https://tavily.com)
2. Set environment variable:
```bash
export TAVILY_API_KEY="your-api-key"
```
3. Restart CCS - Tavily will be added to fallback chain
## MCP Configuration
CCS writes MCP configuration to `~/.claude/.mcp.json`. Example:
```json
{
"mcpServers": {
"web-search-prime": {
"type": "http",
"url": "https://api.z.ai/api/mcp/web_search_prime/mcp",
"headers": {}
},
"brave-search": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-brave-search"],
"env": { "BRAVE_API_KEY": "..." }
}
}
}
```
## Troubleshooting
### WebSearch Not Working
1. **Check config**: Ensure `websearch.enabled: true` in config
2. **Verify MCP**: Check `~/.claude/.mcp.json` exists
3. **Debug mode**: Run with `CCS_DEBUG=1 ccs gemini` for verbose output
### MCP Server Errors
1. **Network issues**: web-search-prime requires internet access
2. **npx failures**: Brave/Tavily require Node.js and npx
3. **API key issues**: Verify env vars are set correctly
### Existing MCP Config
CCS respects existing web search MCP configuration. If you have manually configured web search MCPs, CCS will not overwrite them.
To reset:
1. Remove web search entries from `~/.claude/.mcp.json`
2. Run any CCS third-party profile to regenerate
## Security Considerations
- API keys are stored in environment variables only
- Never commit API keys to version control
- Use `.env` files with proper permissions (chmod 600)
- Dashboard settings are stored in `~/.ccs/config.yaml` (no API keys)
