WHAT IT DOES

What upsert_approval_rule does on Sanka MCP Server

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

RISK

Why upsert_approval_rule is rated Medium

This is a Write operation because it creates or updates (upserts) approval rules—reversible configuration changes. It does not execute arbitrary code, delete data, or move money. However, the medium severity reflects that misconfigured approval rules could disrupt business workflows or inadvertently block critical operations if an AI agent applies inappropriate block_targets like document_download or delivery_send.

From the tool's definition Tool name 'upsert_approval_rule' and description 'Create or update an approval rule' indicate reversible data modification. The tool modifies workflow configuration by creating or updating approval rules that govern how documents and actions are processed.
