web-researcher-mcp
Your AI research assistant that cites real sources and stays honest.
Search the entire web or narrow it down to just the sites you trust;
medical journals, court databases, news outlets, academic papers.
Analyze the full source, not just snippets. Links that work, citations you can trust,
no made up closed garden pre-synthesized results.
