Google Tag Manager MCP

Delete a tag, trigger or variable

delete_entity
DestructiveIdempotent

Delete a tag, trigger, or variable from Google Tag Manager by providing its API path. Simplifies entity removal and enforces the required edit scope.

Instructions

Deletes a tag, trigger or variable by its API path. The response is empty on success. Requires the tagmanager.edit.containers scope.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
pathYesAPI-relative resource path as returned in the resource's own "path" field, e.g. "accounts/1/containers/2/workspaces/3/variables/7".
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description adds valuable behavioral details beyond annotations: the response is empty on success and the operation requires the tagmanager.edit.containers scope. This complements the annotations' destructiveHint and idempotentHint without contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is exceptionally concise: two sentences, front-loaded with the action, then result and scope. No unnecessary words or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple, one-parameter delete tool with full schema coverage and annotations, the description adequately covers action, success behavior, and auth requirement. It is complete for invoking the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with a detailed description of the 'path' parameter including format and example. The description's phrase 'by its API path' reinforces but does not add semantic value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool deletes a tag, trigger, or variable by its API path, specifying the action (delete), resource types, and method. This distinguishes it from sibling tools like create_entity and update_entity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context: delete via API path, empty response on success, and required scope. While it doesn't explicitly mention alternatives or exclusions, the purpose is unambiguous and sufficient for basic usage decisions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
