WHAT IT DOES

What create_page does on M8 Codex MCP

AI agents use create_page to create or update resources in M8 Codex MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your M8 Codex MCP environment.

WHY IT NEEDS A POLICY

Why create_page needs a policy

This tool creates and generates code artifacts (pages, components) within the M8 framework. While it modifies the codebase by adding new generated content, the operation is reversible (generated files can be deleted or regenerated). It does not execute arbitrary operations, delete data irreversibly, or trigger financial transactions.

From the tool's definition Tool name 'create_page' and description explicitly states it 'generates code' (生成代码) and 'automatically completes code generation' (自动完成...生成代码), which creates new artifacts. The description indicates it produces Vue pages and components as output artifacts.
