What folders_create does on Samarth Gtm Mcp
AI agents use folders_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.
Why folders_create is rated Medium
This tool creates a new folder resource in Google Tag Manager, which is a reversible data modification operation. The explicit [WRITE] tag in the description confirms it modifies state. The requirements for GTM_MCP_ENABLE_WRITES=true and confirm=true indicate intentional gating, but the action itself remains a Write category operation.
From the tool's definition [WRITE] Create a GTM folder. Requires GTM_MCP_ENABLE_WRITES=true and confirm=true.
Attacks that exploit this kind of access
The rule that runs folders_create safely

folders_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Samarth Gtm Mcp, apply this rule, and every folders_create call is checked against it from then on.
