google-researcher-mcp — DEPRECATED

⚠️ This project has been superseded by web-researcher-mcp.

A complete rewrite in Go: same tools, but it cites real sources and stays honest — citation verification, retraction flagging, eight search providers behind one interface, and a single signed static binary. No Node.js, no npm.

Migrate in one line

Your API keys and tool calls don't change — only how the server is launched. Pick whichever you prefer (no Node required):

# macOS / Linux — installs the binary and registers it with Claude Code automatically:
curl -fsSL https://raw.githubusercontent.com/zoharbabin/web-researcher-mcp/main/install.sh | sh

# Windows (PowerShell):
powershell -ExecutionPolicy Bypass -c "irm https://raw.githubusercontent.com/zoharbabin/web-researcher-mcp/main/install.ps1 | iex"

# Python users (uv) — run with no install:
uvx web-researcher-mcp
Before / after (MCP client config)

The config keeps the same shape — swap the command/args, keep your env:

// BEFORE — google-researcher-mcp (npx / Node)
{
  "mcpServers": {
    "google-researcher": {
      "command": "npx",
      "args": ["-y", "google-researcher-mcp"],
      "env": { "GOOGLE_CUSTOM_SEARCH_API_KEY": "…", "GOOGLE_CUSTOM_SEARCH_ID": "…" }
    }
  }
}

// AFTER — web-researcher-mcp (installed binary; or use "uvx" + args ["web-researcher-mcp"])
{
  "mcpServers": {
    "web-researcher": {
      "command": "web-researcher-mcp",
      "env": { "GOOGLE_CUSTOM_SEARCH_API_KEY": "…", "GOOGLE_CUSTOM_SEARCH_ID": "…" }
    }
  }
}

Don't run both at once — they register identical tool names. Remove the google-researcher entry before adding web-researcher.

Your existing GOOGLE_CUSTOM_SEARCH_API_KEY and GOOGLE_CUSTOM_SEARCH_ID work unchanged.

Why the Rewrite?

Open IssueResolution in web-researcher-mcp
#108 — Orphan detection fails via npxGo binary has native process lifecycle (EOF/SIGPIPE) — no npm wrapper
#107 — Google discontinuing 'entire web' searchEight providers (Brave, Serper, SearXNG, SearchAPI, Tavily, Exa, DuckDuckGo + Google PSE for lenses) with automatic fallback
#55 — Support alternative search enginesMultiple engines behind one interface, plus a zero-config DuckDuckGo default
#72 — Add Redis cachingHybrid cache: memory + AES-encrypted disk + optional Redis
#40 — Split server.ts into modulesFully modular Go architecture (one package per concern)

Plus what's new: verify_citation and audit_bibliography (catch fabricated/retracted citations), academic / patent / SEC-filing / US-case-law / economic / clinical-trial search, and authority-weighted search lenses.
