GTM MCP Server

GTM MCP Server connects MCP clients to the Google Tag Manager API. It can inspect containers, create and update workspace entities, create versions, and publish a selected version after explicit confirmation.

Use the hosted server at:

https://mcp.gtmeditor.com

The server supports browser-based Google OAuth for individual users and service-account authentication for self-hosted automation.

Project status

Item	Current state
Version in `server.json`	`1.10.1`
Transport	MCP Streamable HTTP
Runtime tools	64 GTM tools by default; 94 with `GTM_TOOL_GROUPS=all`, plus 2 utility tools
MCP resources	8 resource definitions
MCP prompts	6 prompts
Official GTM API coverage	101 of 106 methods
Product parity target	101 of 106 methods, reached
Hosted endpoint	`https://mcp.gtmeditor.com`

The agreed API parity scope is complete. The project implements 101 methods from Google's 106-method GTM v2 discovery surface. The five accounts.user_permissions methods are intentionally excluded because granting and revoking GTM access needs a separate privilege-management design.

Tool count and API-method count are different. Some tools provide local guidance, while some helpers cover more than one Google API call.

Connect an MCP client

Add the hosted URL as a remote HTTP MCP server. The client should discover the OAuth metadata, open Google sign-in, and reconnect with the issued bearer token.

Claude Code

claude mcp add --transport http gtm https://mcp.gtmeditor.com

Gemini CLI

gemini mcp add --transport http gtm https://mcp.gtmeditor.com

Gemini CLI can also use this settings.json entry:

{
  "mcpServers": {
    "gtm": {
      "httpUrl": "https://mcp.gtmeditor.com"
    }
  }
}

Cursor

Add the following to .cursor/mcp.json:

{
  "mcpServers": {
    "gtm": {
      "url": "https://mcp.gtmeditor.com"
    }
  }
}

ChatGPT, Codex, and Claude web

Add a custom or remote MCP connection in the client and use https://mcp.gtmeditor.com as the server URL. Product menus change more often than this server, so refer to the client's current MCP connection instructions if the label differs.

After connecting, try:

List my GTM accounts, containers, and workspaces. Do not make changes.

The Google account used during OAuth determines which GTM accounts the server can access.

Typical workflow

Call list_accounts, list_containers, and list_workspaces to discover IDs. Do not guess IDs.
Inspect the workspace with list/get tools or the audit_container prompt.
Create or update tags, triggers, variables, templates, clients, or transformations in the selected workspace.
Call get_workspace_status and resolve conflicts before versioning.
Call create_version to snapshot the workspace.
Inspect the saved version with get_version.
Call publish_version with confirm: true only when the selected version is ready to go live.
Verify the published state with get_live_version.

Example requests:

"Audit this workspace for duplicate tags and unused triggers."
"Create a GA4 purchase event tag, but do not publish it."
"Show the difference between the latest saved version and the live version."
"Generate a Markdown tracking plan from this workspace."
"Import the iubenda template from the Community Template Gallery."

Tools

All GTM tools use the authenticated Google identity from the current MCP request. Inputs and outputs are structured JSON.

Utility

Tool	Purpose
`ping`	Test MCP connectivity
`auth_status`	Check whether the current request is authenticated

Accounts and containers

Tool	Purpose
`list_accounts`	List accessible GTM accounts
`update_account`	Rename an account
`list_containers`	List containers and their public IDs and settings
`lookup_container`	Find a container by destination ID or GTM public tag ID
`get_container_snippet`	Get a web install snippet or server-container configuration
`create_container`	Create a web, app, AMP, or server container
`update_container`	Rename a container while preserving its other settings
`delete_container`	Permanently delete a container; requires `confirm: true`
`combine_containers`	Merge a source container into a target; requires `confirm: true`
`move_tag_id`	Move a tag ID into a new container; requires confirmation and terms acceptance

Workspaces

Tool	Purpose
`list_workspaces`	List workspaces in a container
`create_workspace`	Create a workspace
`get_workspace`	Get workspace metadata and its current fingerprint
`update_workspace`	Update selected workspace fields
`delete_workspace`	Delete a workspace; requires `confirm: true`
`quick_preview_workspace`	Compile an ephemeral preview without saving or publishing
`get_workspace_status`	Show pending changes and merge conflicts
`bulk_update_workspace`	Apply multiple entity changes; requires `confirm: true`
`resolve_workspace_conflict`	Replace a conflict with a resolved entity; requires `confirm: true`
`sync_workspace`	Synchronize with the latest container version; requires `confirm: true`

Bulk update and conflict resolution accept raw GTM Entity JSON so every entity type supported by the official API remains available.

Tool	Purpose
`list_tags`	List workspace tags
`get_tag`	Get complete tag details
`create_tag`	Create a tag
`update_tag`	Update a tag with fingerprint-based concurrency control
`delete_tag`	Delete a tag; requires `confirm: true`

Triggers

Tool	Purpose
`list_triggers`	List workspace triggers
`get_trigger`	Get complete trigger details
`create_trigger`	Create a trigger
`update_trigger`	Update a trigger with fingerprint-based concurrency control
`delete_trigger`	Delete a trigger; requires `confirm: true`

For update_trigger, omit filterJson, customEventFilterJson, autoEventFilterJson, or parameterJson to preserve the current field. Pass the JSON string "[]" to clear a field, or a non-empty JSON array to replace it. For click, link-click, and form-submission triggers, use filterJson because GTM drops autoEventFilter for those trigger types.

Variables

Tool	Purpose
`list_variables`	List workspace variables
`get_variable`	Get complete variable details
`create_variable`	Create a variable
`update_variable`	Update a variable with fingerprint-based concurrency control
`delete_variable`	Delete a variable; requires `confirm: true`

`get_folder`	Get complete folder metadata
`create_folder`	Create a folder
`update_folder`	Update a folder with fingerprint protection
`delete_folder`	Delete a folder; requires `confirm: true`
`get_folder_entities`	List tags, triggers, and variables assigned to a folder
`move_entities_to_folder`	Move tags, triggers, and variables; requires `confirm: true`
`revert_folder`	Discard workspace folder changes; requires `confirm: true`
`list_built_in_variables`	List enabled built-in variables
`enable_built_in_variables`	Enable built-in variable types
`disable_built_in_variables`	Disable built-in variable types; requires `confirm: true`

Use revert_workspace_entity to discard changes to a built-in variable.

Zones

`get_environment`	Get environment configuration and authorization metadata
`create_environment`	Create a user environment
`update_environment`	Update selected fields with fingerprint concurrency control
`reauthorize_environment`	Rotate the authorization code; requires `confirm: true`
`delete_environment`	Delete a user environment; requires `confirm: true`

The Live and Latest environments are managed by GTM. Creation and deletion apply to user environments; GTM permits URL and debug updates on other types.
