create_project · Portfolio MCP: Risk & Policy

WHAT IT DOES

What create_project does on Portfolio

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

WHY IT NEEDS A POLICY

Why create_project needs a policy

The tool creates new project data in the portfolio system, which is a reversible write operation. It modifies the portfolio state by adding content, but does not execute arbitrary code, delete data irreversibly, or perform financial transactions.

From the tool's definition Tool name is 'create_project' and description states 'Create a new project'. Server description confirms 'full CRUD operations on portfolio content' including create operations. This is a creation/modification action without permanent deletion.

Verdict

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.
