generate-api-routes · Kalendis MCP: Risk & Policy

WHAT IT DOES

What generate-api-routes does on Kalendis MCP

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

WHY IT NEEDS A POLICY

Why generate-api-routes needs a policy

This tool creates new files/code (API routes) in a reversible manner—generated code can be edited, deleted, or regenerated. It does not execute those routes, delete data, move money, or trigger external operations with uncontrolled side effects. While code generation carries some risk if misused (e.g., overwriting existing routes), the primary action is Write (creation/modification of project files).

From the tool's definition Tool 'generate-api-routes' creates API route handlers for Next.js or Express frameworks. The description indicates it generates code artifacts that are written to the project, modifying the codebase.
