WHAT IT DOES

What containers_create does on Samarth Gtm Mcp

AI agents use containers_create to create or update resources in Samarth Gtm Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Samarth Gtm Mcp environment.

RISK

Why containers_create is rated Medium

This tool creates (adds) a new GTM container, which is a reversible write operation. While it modifies the GTM infrastructure, it does not delete data or move funds, and the operation can be undone by deleting the created container. The gating mechanisms (GTM_MCP_ENABLE_WRITES=true and confirm=true) indicate organizational awareness of the write risk.

From the tool's definition Tool name is 'containers_create' and description explicitly states '[WRITE] Create a new GTM container.' The action creates a new container, which is a reversible modification to Google Tag Manager configuration.

RECOMMENDED RULE

The rule that runs containers_create safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Samarth Gtm Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For containers_create, this is the rule to start with:

containers_create Rate-limited

containers_create stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
