share_form · RSpace MCP Server MCP: Risk & Policy

WHAT IT DOES

What share_form does on RSpace MCP Server

AI agents use share_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 share_form needs a policy

This tool modifies access control and collaboration settings for a form by sharing it with groups. While it doesn't create new data or delete anything, it does change the form's metadata and permissions state in RSpace, making it a reversible Write action.

share_form Rate-limited

share_form 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.
