AI agents use update_smart_list to create or update resources in GoHighLevel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment.
This tool creates or modifies data (smart lists) in the GoHighLevel CRM system. Smart lists are typically used for contact segmentation and filtering in CRM systems. Updating a smart list is a Write operation—it changes existing data but is reversible (the list can be updated again or restored).
From the tool's definition Tool name is 'update_smart_list' and description states 'Update a smart list'. Update operations modify data reversibly without deletion or irreversible changes.
Documented attack patterns abuse exactly the kind of access update_smart_list 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 update_smart_list:
{
"version": "1",
"default": "deny",
"tools": {
"update_smart_list": {
"limits": [
{
"counter": "update_smart_list_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_smart_list 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.
Free to start. No card required.
Update a smart list. It is categorised as a Write tool in the GoHighLevel MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the GoHighLevel MCP Server MCP server in PolicyLayer and add a rule for update_smart_list: 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.
update_smart_list is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_smart_list 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 update_smart_list. 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.
update_smart_list 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.
