Update object schema properties including labels, description, and searchable fields
AI agents use update_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 tool modifies system schema/configuration properties (labels, descriptions, searchable fields) rather than instance data. While it creates or modifies data reversibly without permanent deletion, it affects system-wide schema which could impact multiple records and workflows. Classified as Write rather than Execute because it directly modifies metadata rather than executing code/commands.
From the tool's definition Tool name 'update_object_schema' combined with description stating it updates 'object schema properties including labels, description, and searchable fields' indicates modification of data structure definitions.
Documented attack patterns abuse exactly the kind of access update_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 update_object_schema:
{
"version": "1",
"default": "deny",
"tools": {
"update_object_schema": {
"limits": [
{
"counter": "update_object_schema_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_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.
Free to start. No card required.
Update object schema properties including labels, description, and searchable fields. 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_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.
update_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 update_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 update_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.
update_object_schema is provided by the GoHighLevel MCP Server MCP server (mastanley13/gohighlevel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
