ConvRadar is a hosted Model Context Protocol server. It connects to your Google Analytics 4 property over OAuth (read-only) and exposes 22 conversion-diagnostic tools to any MCP-compatible client — Claude, ChatGPT, Cursor, Cline.

This page is the reference for the connector: the endpoint, the OAuth flow, the scopes, and every tool the server exposes. If you just want to try it, the demo at /chat gives you 3 free messages with no signup.

Endpoint

TransportStreamable HTTP
URLhttps://mcp.convradar.com/mcp
AuthOAuth 2.1, Bearer token in Authorization header
DiscoveryGET /.well-known/oauth-protected-resource (RFC 9728)

Auth and scopes

ConvRadar uses OAuth 2.1 with PKCE. There are no per-user URLs and no manual API key — the client walks the discovery handshake on the protected resource and is redirected to the authorization server on first call.

The two scopes the server requests:

  • read:metrics — read GA4 metrics, dimensions, funnel data and traffic breakdowns. Required for every diagnostic tool.
  • write:hypotheses — store and retrieve hypotheses tied to the account so future conversations resume where the last one ended.

The downstream OAuth to Google asks only for read-only GA4 access. ConvRadar cannot modify your analytics data.

Connect a client

Stdio-only clients (Claude Desktop, Cursor, Cline, Continue) connect through mcp-remote, which handles the OAuth handshake the first time you call a tool. Add this block to the client's MCP config:

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

Web clients use a native connector menu:

  • Claude.ai — Settings → Connectors → Add custom connector. URL: https://mcp.convradar.com/mcp. OAuth is handled automatically.
  • ChatGPT (Plus / Pro) — Settings → Connectors → Add custom MCP connector with the same URL.
  • Glama, Smithery — add the connector through the registry UI; both walk the OAuth flow for you.

On first tool call a browser window opens to authorize the Google account that owns your GA4 property. The token is stored by the client and refreshed automatically.

Tools

The MCP client picks the right tool for each question; you do not usually call them by name. All tools are namespaced cr_* so they will not collide with other connectors.
