AI agents use send_estimate 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 and sends an estimate, which is a write operation that generates a new business document and initiates communication. While reversible (estimates can be cancelled, resent, or superseded), it has high severity because sending an incorrect or fraudulent estimate to a customer could commit the business to unfavorable terms, damage customer relationships, or be used for deceptive purposes.
From the tool's definition Tool name is 'send_estimate' with description 'Send an estimate to customer'. This creates/sends a new estimate document to a customer, which is a reversible write operation that modifies business state (estimate record created/sent).
Documented attack patterns abuse exactly the kind of access send_estimate 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 send_estimate:
{
"version": "1",
"default": "deny",
"tools": {
"send_estimate": {
"limits": [
{
"counter": "send_estimate_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}send_estimate 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.
Send an estimate to customer. 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 send_estimate: 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.
send_estimate 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 send_estimate 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 send_estimate. 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.
send_estimate 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.
