47 of ServiceTitan MCP Server's 108 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.
PolicyLayer is an MCP gateway — it sits between your AI agents and ServiceTitan MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:
{
"servicetitan_create_payment": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
} Financial tools should be explicitly enabled per use case, not open by default.
{
"servicetitan_cancel_appointment": {
"deny_if": [
{
"conditions": [],
"on_deny": "Blocked by default. Requires approval."
}
]
}
} Destructive tools should never be available to autonomous agents without human approval.
{
"servicetitan_add_customer_tag": {
"limits": [
{
"counter": "servicetitan_add_customer_tag_per_hour",
"window": "hour",
"max": 30,
"scope": "grant"
}
]
}
} Prevents bulk unintended modifications from agents caught in loops.
{
"servicetitan_deactivate_technician": {
"limits": [
{
"counter": "servicetitan_deactivate_technician_per_minute",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
} Controls API costs and prevents retry loops from exhausting upstream rate limits.
Instant setup, no code required.
Other MCP servers with similar tools — same risk classification, starter policies for each.
Yes. The ServiceTitan MCP Server server exposes 1 financial tools including servicetitan_create_payment. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.
Yes. The ServiceTitan MCP Server server exposes 9 destructive tools including servicetitan_cancel_appointment, servicetitan_cancel_job, servicetitan_cancel_membership. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.
The ServiceTitan MCP Server server has 37 write tools including servicetitan_add_customer_tag, servicetitan_add_estimate_item, servicetitan_add_invoice_item. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach ServiceTitan MCP Server.
108 tools across 4 categories: Destructive, Financial, Read, Write. 61 are read-only. 47 can modify, create, or delete data.
Register the ServiceTitan MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
