What codex_create_project does on Sage MCP
AI agents use codex_create_project to create or update resources in Sage MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
Why codex_create_project is rated Medium
This tool creates a new project, which is a reversible write operation. It does not delete data or execute code. Severity is medium because creating projects in an organization can affect organizational structure, permissions, and resource allocation, but it is generally reversible by deleting the project afterward.
From the tool's definition "Create a new project in the organization"

The rule that runs codex_create_project safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sage MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For codex_create_project, this is the rule to start with:
codex_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Sage MCP, apply this rule, and every codex_create_project call is checked against it from then on.
