AI agents use update_snippet 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.
The tool creates or modifies data reversibly by updating an existing snippet. While snippets are typically low-blast-radius content (templates or text blocks), their modification in a CRM context could affect automated messaging, customer communications, or business processes. The change is reversible (can be updated again), so it does not meet the Destructive threshold.
From the tool's definition Tool name is 'update_snippet' and description states 'Update a snippet' — this modifies existing data (a snippet, likely reusable text/content) reversibly within the GoHighLevel CRM system.
Documented attack patterns abuse exactly the kind of access update_snippet 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_snippet:
{
"version": "1",
"default": "deny",
"tools": {
"update_snippet": {
"limits": [
{
"counter": "update_snippet_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_snippet 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.

Update a snippet. 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_snippet: 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_snippet 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_snippet 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_snippet. 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_snippet 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.
