WHAT IT DOES

What sign_contract does on Businys

AI agents use sign_contract to create or update resources in Businys, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Businys environment.

RISK

Why sign_contract is rated Medium

Signing a contract creates a legally binding commitment on behalf of the user. While it is technically a write operation (adding a signature/record), it carries high severity because it creates legal obligations that may be difficult or impossible to reverse. It does not move money directly, so Financial is not the primary category, but misuse could lead to unintended legal agreements.

RECOMMENDED RULE

The rule that runs sign_contract safely

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

sign_contract Rate-limited

sign_contract 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.
