Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

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.

⭐ If you're tired of AI making things up, and web-researcher-mcp helps you, give us a star ⭐ — it helps more teams discover the project.

Questions

What is the Web Researcher MCP server?

Give your AI assistant real web search, full-page reading, and multi-source research with citations that are never fabricated.

Is Web Researcher safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it C (73/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Web Researcher need?

It reads BRAVE_API_KEY, EXA_API_KEY, GOOGLE_CUSTOM_SEARCH_API_KEY, SEARCHAPI_API_KEY, SERPER_API_KEY, TAVILY_API_KEY and XQUIK_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Web Researcher run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as smithery-cli-pin.

How current is this page?

The grade is for one exact copy of the source (7d1fd8a48f8b), read on 2026-10-08. The repository is watched and re-audited when it changes.
