    Google Tag Manager MCP for your AI agent

    Cogny's Google Tag Manager integration exposes 37 tools (20 read, 12 write, 5 destructive) to an AI agent over MCP. The same tools are available on every plan, from your own AI client or inside the Cogny app.

    • 20readonly reads data.
    • 12writecreates or changes something.
    • 5destructivedeletes, removes or replaces something.

    Over MCP your own AI client asks before it runs a write. To take a tool away from your agent, block it in Settings → Integrations. Plans, approvals and limits

    set it up.

    Add Cogny to your AI client once, then connect Google Tag Manager in Cogny. Every Google Tag Manager tool below appears in the client.

    • Claude.aiSettings → Connectors → Add custom connector, URL https://app.cogny.com/mcp, then log in and pick your workspace.
