### Description (declared)

# MCP Ferris Search

A blazing-fast MCP (Model Context Protocol) server for multi-engine web search, written in Python.

This is a Python implementation inspired by the original [ferris-search](https://github.com/lispking/ferris-search) Rust project.

## Features

- **Multi-engine fan-out** — search across multiple engines simultaneously with a single call
- **9 search engines** — Bing, DuckDuckGo, Brave, Baidu, CSDN, Juejin, Zhihu, GitHub, GitHub Code
- **7 MCP tools** — `web_search` + 6 content fetchers
- **No API keys required** for most engines (Brave requires API key)
- **Proxy support** — HTTP/SOCKS5 proxy via environment variables
