What is Web Researcher MCP?

web-researcher-mcp is a free, open-source MCP (Model Context Protocol) server that gives AI assistants real web search with citations that actually check out.

Instead of letting your AI hallucinate sources or pull from a closed, opaque index, you tell it exactly which sites to search — peer-reviewed journals, court databases, SEC filings, news outlets, patent offices, and more. We call these "search lenses."

Key capabilities: • Web, image, and news search across 30+ lenses (medical, legal, financial, academic, tech, and more) • Full-page extraction — reads entire articles, PDFs, Word docs, YouTube transcripts, and Hacker News threads • Academic search with real DOIs, citation graphs, and open-access links • Patent search (US, EU, international) • SEC EDGAR filing search for public-company documents • US court opinions and dockets via CourtListener • Economic data from World Bank, OECD, Eurostat, and FRED • Clinical trial search via ClinicalTrials.gov • Citation verification — checks if a source exists, matches a real record, and isn’t retracted • Bibliography auditing — validates an entire reference list in one pass • Multi-step deep research with session persistence and export • Formatted bibliographies in APA, MLA, BibTeX, RIS, and CSL-JSON

Compared to Perplexity (which gets citations wrong ~37% of the time) or ChatGPT’s built-in search, this tool verifies every link is real and every paper actually exists before citing it.

Runs on your machine — no data leaves to a third party. Free forever. Works with no API key out of the box (DuckDuckGo fallback); plug in Google, Brave, Exa, Tavily, or others for richer results.
