ClimbPast MCP

Read and edit GA4, Search Console and Google Tag Manager from any AI.

ClimbPast is a hosted MCP (Model Context Protocol) server that connects Google Analytics 4, Google Search Console and Google Tag Manager to Claude, ChatGPT, Cursor, or any MCP client. 29 tools. Read-only by default; write access is opt-in and revocable.

Most analytics MCP servers can only read. ClimbPast writes: register GA4 custom dimensions and key events, submit sitemaps, check whether a URL is actually indexed, and create, edit and publish Tag Manager containers, from chat.

Quickstart

Sign up at climbpast.com, connect your Google account, and copy your cp_ API key from the dashboard. Then connect your client:

Claude Code

Terminal

claude mcp add --transport http climbpast https://climbpast.com/api/mcp --header "Authorization: Bearer cp_YOUR_KEY"

claude.ai (custom connector)

Settings > Integrations > Add custom connector:

Field	Value
Name	ClimbPast
URL	`https://climbpast.com/api/mcp`
Auth type	Bearer token
Token	your `cp_` key

Cursor / any MCP client

Add to your MCP config (mcpServers):

config.json

{
  "climbpast": {
    "type": "http",
    "url": "https://climbpast.com/api/mcp",
    "headers": {
      "Authorization": "Bearer cp_YOUR_KEY"
    }
  }
}

Then ask things like:

"How much traffic did ChatGPT, Perplexity and Claude send us this month?"
"Register plan_type as a custom dimension in GA4."
"Is /pricing indexed? If not, resubmit the sitemap."
"Create a GTM tag that fires on the signup button and publish the container."

Security model

Your AI holds a cp_ API key, never your Google account credentials.
Read-only by default. Write tools require enabling write access in Settings, which triggers a separate Google consent screen.
Keys are revocable from the dashboard in one click. Revoke the key and access is gone.

Support and feature requests

If there's a GA4, Search Console or GTM operation you still do by hand, open an issue. Requests genuinely drive the roadmap.
