AI agents call get_caller_ids to retrieve information from GoHighLevel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists verified caller IDs from the GoHighLevel CRM system. It performs a read-only query operation with no side effects, no data modification, and no execution capabilities. The blast radius of misuse is minimal—an attacker could view what caller IDs are registered but cannot create unauthorized caller IDs, make calls, or modify system state.
From the tool's definition Tool name 'get_caller_ids' and description 'Get verified caller IDs' indicate a retrieval operation that queries existing caller ID data without modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access get_caller_ids gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GoHighLevel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_caller_ids:
{
"version": "1",
"default": "deny",
"tools": {
"get_caller_ids": {}
}
}get_caller_ids is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get verified caller IDs. It is categorised as a Read tool in the GoHighLevel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GoHighLevel MCP Server MCP server in PolicyLayer and add a rule for get_caller_ids: 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 GoHighLevel MCP Server. Nothing to install.
get_caller_ids 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 get_caller_ids 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 get_caller_ids. 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.
get_caller_ids is provided by the GoHighLevel MCP Server MCP server (busybee3333/go-high-level-mcp-2026-complete). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
