Restart & Authenticate

Restart Claude Desktop. A browser window will open for Google OAuth authentication. Complete the flow to grant access to your Google Tag Manager account.

Manual Configuration (Advanced)

If you prefer to manually edit your config, add this to your mcpServers section:

"google-tag-manager-mcp-server": {
  "command": "npx",
  "args": [
    "-y",
    "mcp-remote",
    "https://gtm-mcp.filamentanalytics.com/sse"
  ]
}

Troubleshooting

Clearing Authentication Issues:

If you encounter persistent authentication issues, mcp-remote stores credentials in ~/.mcp-auth. Clear this directory to reset: 

rm -rf ~/.mcp-auth

Then restart your MCP client to re-authenticate.
