What ConvRadar does

ConvRadar is a hosted Model Context Protocol (MCP) server. It connects to your Google Analytics 4 property over OAuth (read-only) and exposes 39 conversion-diagnostic tools to any MCP client.

Runs a full audit on demand — funnel drops, traffic-quality regressions, device gaps, landing-page leaks, product/category performance.
Compares segments, periods and benchmarks. Answers in plain English with GA4 numbers attached.
Records hypotheses so the next conversation picks up where the last one ended.

Works with any GA4 property

ConvRadar isn't e-commerce-only. On connect it detects what kind of property you have and adapts the metrics, funnel and benchmarks to match — so the numbers make sense whether or not you sell anything on-site.

E-commerce — product and category performance, the add-to-cart → checkout → purchase funnel, revenue and AOV.
SaaS — sign-ups, trials and activation as the conversion funnel; engagement where there's no cart.
Lead generation — form submits, demo requests, contact and quote events mapped into a real lead funnel.
Mobile & web apps — app engagement, key-event completion and retention-shaped questions.
Content, media and everything else — engagement, read depth and whatever key events you've defined.

If a property has no e-commerce tracking, ConvRadar won't hand you a misleading 0% conversion rate or $0 revenue. It leads with engagement and the key events you actually fire, and tells you when a metric isn't available instead of reporting a zero as fact.

Try without installing

The connector is the deep end. Five instruments on the site cover the shallow end, and three of them run without an account:

Tool	What it does	Access
📊 Conversion Audit	Connect GA4 and get an audit of your real traffic: ranked leaks with the numbers behind each and a prioritized fix list.	Free sign-up + GA4
🩺 Page Scan	Paste any URL. GPT and Claude read the desktop and mobile page against our pattern library and pin each leak to the screenshot.	No login
⚡ Page Speed & UX Check	Google PageSpeed score, a screenshot and the design issues costing sales, in about a minute.	No login
🕹️ Benchmarks	Conversion-rate ranges by industry — see where you land before chasing a number.	No login
🗣️ Voice of Customer	Paste your URL — it mines independent customer discussion across your category (Reddit, Quora, niche forums & social threads; your brand's own reviews excluded), ranks the pains by frequency with verbatim quotes and their source links, then grades your page copy against each pain and hands you a prioritized fix list. ~3–5 min per run, report by email.	Free sign-up

Connect your client

ConvRadar is a remote OAuth-protected MCP. Any stdio-only client (Claude Desktop, Cursor, Cline, Continue) can connect via mcp-remote, which handles the OAuth handshake on first run.

Claude Desktop / Cursor / Cline

Add this to your client's MCP config (claude_desktop_config.json, ~/.cursor/mcp.json, etc.):

config.json

{
  "mcpServers": {
    "convradar": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.convradar.com/mcp"]
    }
  }
}

Restart the client. On first tool call, a browser window opens for OAuth — sign in with the same Google account that owns your GA4 property.

First prompts to try

After connecting, try:

Run a full audit of my account.
Where's my biggest funnel drop?
Did mobile conversion drop last week?
Compare desktop and mobile checkout conversion for the last 30 days.
What should I A/B test next?

Auth

Protocol: OAuth 2.1, Bearer token in Authorization header.
Scopes: read:metrics, write:hypotheses.
Discovery (RFC 9728): GET https://mcp.convradar.com/.well-known/oauth-protected-resource.
No per-user URLs — mcp-remote (or the client's built-in OAuth flow) handles the login on first run.

The OAuth flow only requests read-only GA4 access — ConvRadar can never modify your analytics data.

Pricing

Free right now — ConvRadar is in open beta. No card, no trial countdown. Connect GA4 and use every tool. Each account has 1,000 tool calls a day, and every tool result reports how many are left.

When the beta ends it becomes $9.99 / month flat (7-day free trial, cancel anytime). Beta users get advance notice before that kicks in.
