publish_form · RSpace MCP Server MCP: Risk & Policy

WHAT IT DOES

What publish_form does on RSpace MCP Server

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

WHY IT NEEDS A POLICY

Why publish_form needs a policy

Publishing a form is a reversible modification of metadata/configuration state that enables or exposes functionality. It does not delete, execute arbitrary code, nor does it move money. While publishing could facilitate document creation by others, the tool itself performs only the write operation of changing a form's availability status.

From the tool's definition Tool description states it "Makes a form available for creating documents". The verb 'makes available' indicates a state change that enables document creation, which is a write operation that modifies form configuration.
