magento_index · Magector MCP: Risk & Policy

WHAT IT DOES

What magento_index does on Magector

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

WHY IT NEEDS A POLICY

Why magento_index needs a policy

This tool builds or updates a search index from the codebase files. It writes/modifies index data, but does not delete source code or execute arbitrary commands. The operation is reversible in the sense that re-indexing can be re-run, making Write the appropriate category. Misuse could cause a stale or corrupted index, but blast radius is limited to search functionality.

From the tool's definition 'Index or re-index the Magento codebase for semantic search. Run this after code changes to update the search index.'
