WHAT IT DOES

What send_sms does on GoHighLevel MCP Server

AI agents use send_sms 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.

RISK

Why send_sms is rated Medium

Sending an SMS message creates an outbound communication to a real person. It is a reversible write action (the message is sent but no data is permanently deleted), though misuse could cause spam, harassment, or reputational harm at scale — hence high severity. It does not execute code, delete data, or move money.

RECOMMENDED RULE

The rule that runs send_sms safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GoHighLevel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For send_sms, this is the rule to start with:

send_sms Rate-limited

send_sms 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.
