Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
GA4 conversion analyst inside Claude — funnel drops, traffic anomalies, device gaps, with numbers.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 3 months ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Hosted MCP server that turns your Google Analytics 4 property into a conversation. Ask "where's my biggest funnel drop?" or "did mobile conversion drop last week?" in Claude, ChatGPT, Cursor or Cline — ConvRadar pulls the right slice, runs the diagnostic, and answers with numbers and a recommended action.
https://mcp.convradar.com/mcpThis repository is the public manifest for the hosted ConvRadar MCP server. The server itself is a managed service — there is no self-hosted binary. Use the configuration below to connect any MCP-compatible client to it.
Live output from the connector — funnel audit on the demo tenant in Claude.ai, traffic-quality verdict in ChatGPT. Full set with paired prompts in media/.
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.
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.
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.
Sign in at https://convradar.com/chat with an email link or Google, connect GA4 and ask the same questions in the browser. Free during the open beta, no card. Page Scan, Page Speed and Benchmarks below need no login at all.
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 |
The public skills catalog contains two workflows: SaaS Page Audit for one SaaS pricing, product or service page, and E-commerce & Lead Gen Audit for a whole store or service lead-generation site. Both produce an evidence-backed HTML report and use connected GA4 data when appropriate. The E-commerce & Lead Gen skill keeps separate rules for purchases and enquiries and excludes SaaS.
The hosted MCP server serves the same skill files for ChatGPT plugin import. GitHub is the readable source; a plugin version receives its own snapshot during Scan Tools. See the catalog index.
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.
Add this to your client's MCP config (claude_desktop_config.json, ~/.cursor/mcp.json, etc.):
{
"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.
Add a Custom Connector in Settings → Connectors:
https://mcp.convradar.com/mcpConvRadar is an official plugin in ChatGPT's plugin directory: open ConvRadar in ChatGPT, click Connect and sign in with Google. No Developer Mode, no URL to paste.
Install the plugin from antigravity-plugin/: agy plugin install ./convradar-mcp/antigravity-plugin from a clone of this repo. It adds the remote server and both audit skills; sign-in runs over OAuth on the first call.
ConvRadar exposes the following tools. The MCP client picks the right one for each question; you don't usually call them by name.

After connecting, try:
Authorization header.read:metrics, write:hypotheses.GET https://mcp.convradar.com/.well-known/oauth-protected-resource.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.
