WHAT IT DOES

RISK

Why create_approval_request is rated Medium

This tool creates a new approval request record in the system, which is a reversible Write operation. It modifies system state by adding an approval workflow item but does not irreversibly delete data, execute arbitrary code, move money, or directly modify existing records.

From the tool's definition Tool name is 'create_approval_request' and description states 'Create an ad hoc approval request' — the verb 'create' and explicit mention of creating a request indicate this writes/creates data.

RECOMMENDED RULE

The rule that runs create_approval_request 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 create_approval_request, this is the rule to start with:

create_approval_request Rate-limited

create_approval_request 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.
