### Description (declared)

# Searchlight

Free, open-source web search MCP server for AI coding tools.

Works with **Claude Code**, **Cursor**, **Windsurf**, **VS Code Copilot**, and any MCP-compatible AI tool. Zero API keys required — install, add one line to your MCP config, and start searching.

## Features

- **Zero cost** — Free search via native HTTP scraping (Bing, Baidu, Yandex, Brave, DuckDuckGo)
- **Zero config** — Works out of the box with `auto` backend and language-aware routing
- **7 search engines** with automatic failover and reachability probing
- **4 MCP tools** — `web_search`, `web_read`, `web_search_and_read`, `search_config`
- **Quality Site Library** — Auto-enhances queries with authoritative sources (Anthropic, OpenAI, MCP docs, LangChain, etc.)
- **Smart content extraction** — trafilatura → readability → BeautifulSoup fallback chain with quality scoring
- **JS page rendering** — Automatic Jina AI proxy fallback for JavaScript-rendered pages
- **Smart caching** — Async SQLite with dynamic TTL (time-sensitive queries cache shorter)
- **Auto-learning** — Automatically discovers and adds high-quality websites from your reading patterns
- **Security** — Automatic API key/secret detection and redaction in queries
