create_sample · RSpace MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_sample does on RSpace MCP Server

AI agents use create_sample 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 create_sample needs a policy

The 'create_sample' tool creates new data objects (samples) in RSpace, which is reversible (samples can be deleted or modified). This is a Write operation rather than Read (retrieves existing data), Execute (runs arbitrary code), Destructive (irreversibly deletes), or Financial (moves money).

From the tool's definition Tool name is 'create_sample' and sibling tools include 'bulk_create_samples', 'create_document_from_form', 'create_form', 'create_grid_container', etc., establishing a clear pattern of data creation tools.

Verdict

create_sample Rate-limited

create_sample 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.
