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⚠️ This project has been superseded by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-researcherentry before addingweb-researcher.
Your existing GOOGLE_CUSTOM_SEARCH_API_KEY and GOOGLE_CUSTOM_SEARCH_ID work unchanged.
Why the Rewrite?
| Open Issue | Resolution in web-researcher-mcp |
|---|---|
| #108 — Orphan detection fails via npx | Go binary has native process lifecycle (EOF/SIGPIPE) — no npm wrapper |
| #107 — Google discontinuing 'entire web' search | Eight providers (Brave, Serper, SearXNG, SearchAPI, Tavily, Exa, DuckDuckGo + Google PSE for lenses) with automatic fallback |
| #55 — Support alternative search engines | Multiple engines behind one interface, plus a zero-config DuckDuckGo default |
| #72 — Add Redis caching | Hybrid cache: memory + AES-encrypted disk + optional Redis |
| #40 — Split server.ts into modules | Fully 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.
