How to install

Runs on your machine from its package; the steps are below.

What it does

  1. Reads
  2. Writes
  3. High impact

At most: only reads or looks up information.

What it costs

Free

Odel charges nothing per call. The publisher may charge for its own service.

Runs locally over stdio

This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).

npmgoogle-researcher-mcpv6.3.3

Run

npx -y google-researcher-mcp

MCP client config

{
  "mcpServers": {
    "google-researcher": {
      "command": "npx",
      "args": [
        "-y",
        "google-researcher-mcp"
      ]

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⚠️ This project has been superseded by web-researcher-mcp.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

bash
# 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:

jsonc
// 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.
