create_project · Openl MCP: Risk & Policy

WHAT IT DOES

What create_project does on Openl

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

WHY IT NEEDS A POLICY

Why create_project needs a policy

Creating a project and committing it to a repository is a reversible write operation. While it modifies the repository state, it does not irreversibly delete data (which would be Destructive), execute arbitrary code (Execute), nor move financial assets (Financial). The operation can be undone through version control mechanisms.

From the tool's definition Tool description states 'Create a new OpenL project in a design repository and commit it' — this creates and persists new data in a repository via commit operation.

create_project Rate-limited

create_project 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.
