AI agents use update_sms_template 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 (an SMS template) in a reversible manner. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or retrieve data (Read). The modification of SMS templates could affect customer communications if misused by an AI agent, hence medium severity. High confidence because the intent is clear from both name and description.
From the tool's definition Tool name is 'update_sms_template' and description states 'Update an SMS template', which modifies an existing configuration object reversibly within the CRM system.

"default": "deny",
"tools": {
"update_sms_template": {
"limits": [
{
"counter": "update_sms_template_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
