create_space · Dart MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_space does on Dart MCP Server

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

WHY IT NEEDS A POLICY

Why create_space needs a policy

Creating a new space is a reversible operation that establishes a new organizational container in the workspace. It modifies the system state by adding data but does not execute arbitrary code, delete data irreversibly, or commit financial transactions. The low severity reflects that misuse would typically result in unwanted workspace clutter rather than data loss or system compromise.

From the tool's definition Tool name is 'create_space' and description states 'Create a new space'. The verb 'create' indicates data creation without irreversible deletion or financial impact.

create_space Rate-limited

create_space 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.
