AI agents use create-custom-object-schema 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.
Creating custom object schemas is a Write operation as it creates new, structured data definitions in the GoHighLevel system. While reversible (schemas can be modified or deleted), the action modifies the system's data model and could impact how business data is organized and processed.
From the tool's definition Tool description states 'Allows you to create a custom object schema' - directly creates new data structures within the system that persist and organize business data.
Documented attack patterns abuse exactly the kind of access create-custom-object-schema 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 create-custom-object-schema:
{
"version": "1",
"default": "deny",
"tools": {
"create-custom-object-schema": {
"limits": [
{
"counter": "create-custom-object-schema_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-custom-object-schema 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.

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 create-custom-object-schema: 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.
create-custom-object-schema 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 create-custom-object-schema 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 create-custom-object-schema. 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.
create-custom-object-schema is provided by the GoHighLevel MCP Server MCP server (drausal/gohighlevel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GoHighLevel MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
