What send_message does on GoHighLevel MCP Server
AI agents use send_message 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.
Why send_message is rated Medium
This tool creates new message records within a conversation, which is a reversible Write operation. It modifies conversation state by adding content but does not execute code, delete data, or move money.
From the tool's definition Tool name 'send_message' combined with description 'Send a message in a conversation' indicates creating/adding new message data to an existing conversation thread.
Attacks that exploit this kind of access
The rule that runs send_message 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_message, this is the rule to start with:
send_message 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.
The button opens the PolicyLayer dashboard: create your workspace, connect GoHighLevel MCP Server, apply this rule, and every send_message call is checked against it from then on.
