It does not execute arbitrary code, delete data irreversibly, or move money. While it could have downstream effects if misused to create misleading relationships, the primary action is Write (create).
From the tool's definition Tool name contains 'create_association' and description states 'Create a new association that defines relationship types between entities'. This is a creation operation that modifies data by establishing new relationships.
Attacks that exploit this kind of access
The rule that runs ghl_create_association safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ghl, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ghl_create_association, this is the rule to start with:
ghl_create_association 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 Ghl, apply this rule, and every ghl_create_association call is checked against it from then on.
