RISK

Why create_service is rated Medium

This tool creates new service offerings in the CRM, which is a reversible write operation. It establishes business-critical entities (services with pricing and policies) that affect customer-facing functionality and revenue operations. The moderate severity reflects that while it doesn't delete data or move money, misconfiguration could disrupt service availability or introduce incorrect pricing.

From the tool's definition Tool name 'create_service' and description 'Create a bookable service. Sets duration, price, capacity, and policies' indicates data creation that modifies the CRM state.

RECOMMENDED RULE

The rule that runs create_service safely

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

create_service Rate-limited

create_service 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.

}
