AI agents call list_users to retrieve information from Ghl without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries user/team member information from a GoHighLevel location without creating, modifying, deleting, or executing operations. It is a standard read operation with minimal blast radius if misused by an AI agent—the worst case is unauthorized visibility into user roster information.
From the tool's definition Tool name 'list_users' and description 'List users or team members in the configured GoHighLevel location' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
List users or team members in the configured GoHighLevel location. It is categorised as a Read tool in the Ghl MCP Server, which means it retrieves data without modifying state.
Register the Ghl MCP server in PolicyLayer and add a rule for list_users: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ghl. Nothing to install.
list_users is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_users rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_users. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_users is provided by the Ghl MCP server (snack-jpg/ghl-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
