Create a new custom object schema with labels, key, and primary display property
AI agents use create_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.
This is a Write operation because it creates and stores new data (a custom object schema) that is reversible—the schema can be modified or deleted later. The severity is medium because misconfiguration or abuse could create unwanted data structures that clutter the CRM system or potentially enable downstream injection/validation bypass attacks, but the immediate blast radius is contained to schema definitions rather…
From the tool's definition Tool name 'create_object_schema' and description 'Create a new custom object schema' indicate the tool creates new data structures (custom object schemas) with configurable properties (labels, key, primary display property).
Documented attack patterns abuse exactly the kind of access create_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_object_schema:
{
"version": "1",
"default": "deny",
"tools": {
"create_object_schema": {
"limits": [
{
"counter": "create_object_schema_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_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.

Create a new custom object schema with labels, key, and primary display property. 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_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_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_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_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_object_schema 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.
