RISK

Why update_bill is rated Medium

This tool modifies existing billing records reversibly through an update operation. It is categorized as Write rather than Destructive because updates are non-destructive and reversible. Severity is medium because bill modifications could affect financial records and business operations, but the actual financial impact depends on what values are changed and requires an authorized user to invoke the operation.

From the tool's definition Tool name 'update_bill' and description 'Update an existing bill in Sanka' indicates modification of existing bill records.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_bill safely

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

update_bill Rate-limited

update_bill 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.
