submit_application · Crosswalk MCP: Risk & Policy

WHAT IT DOES

What submit_application does on Crosswalk

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

WHY IT NEEDS A POLICY

Why submit_application needs a policy

This tool changes application status from draft/pending to submitted, which is a reversible write operation (the application state can theoretically be reset or modified later, unlike a destructive delete).

From the tool's definition submit_application marks an application as submitted, indicating a state change in the application workflow. The description fragment shows this creates or modifies application state records.
