update_order · Sevdesk MCP: Risk & Policy

WHAT IT DOES

What update_order does on Sevdesk

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

WHY IT NEEDS A POLICY

Why update_order needs a policy

Updating an order modifies business-critical financial data (order terms, amounts, line items, customer details, etc.) reversibly within sevdesk's accounting system. This is a Write operation rather than Financial because the tool itself doesn't transfer money or create financial obligations—it updates order records.

From the tool's definition Tool name 'update_order' and description 'Update an existing order in sevdesk' indicate modification of existing business data. The broader server context shows this is an accounting/invoicing system where orders are financial documents.
