MCP server for Google Tag Manager
Google tag manager mcp server connects Google Tag Manager to AI assistants that speak the Model Context Protocol. MCP server for Google Tag Manager.
This is a server that supports remote MCP connections, with Google OAuth built-in and provides an interface to the Google Tag Manager API.
Once connected, the assistant can call this tool directly:
Troubleshooting — Some MCP clients (like Cursor AI) have a 60-character limit for the combined MCP server name + tool name length. If you use a longer server name in yourThe server is distributed via npm as npm, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Before the server will start you need to supply 4 environment variables: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, COOKIE_ENCRYPTION_KEY, WORKER_HOST. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Google Tag Manager sits in that group, and the shape of its toolset — Troubleshooting — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
