One Search Mcp

yokingma/one-search-mcp

Gives Claude access to web search through multiple providers, including a free local browser option that needs no API keys. Exposes four tools: one_search for querying engines like SearXNG, Tavily, DuckDuckGo, Bing, and Google; one_scrape for extracting content from pages; one_map for crawling sites; and one_extract for preprocessing multi-URL content. The local mode uses agent-browser with your existing Chrome or Edge install to automate searches. Reach for this when you need Claude to search the web or scrape content without committing to a specific search API. The Docker image bundles Chromium if you want zero setup. Switched from Firecrawl to agent-browser in recent versions for better privacy and lower costs.
