Why delete_tag is rated Critical
This tool permanently deletes a tag and strips it from all entities that reference it. This is an irreversible operation affecting potentially many records, making it Destructive rather than merely Write.
From the tool's definition The tool description explicitly states 'Delete a CRM tag and remove it from all tagged entities.' This irreversibly removes data (the tag itself) and modifies associated records across the CRM system.
Attacks that exploit this kind of access
The rule that runs delete_tag safely
PolicyLayer is an MCP gateway: it sits between your AI agents and FavCRM, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_tag, this is the rule to start with:
delete_tag is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect FavCRM, apply this rule, and every delete_tag call is checked against it from then on.
