WHAT IT DOES

What update-document-type does on Mcp Dev

AI agents use update-document-type to create or update resources in Mcp Dev, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Dev environment.

RISK

Why update-document-type is rated Medium

This tool creates or modifies data reversibly by updating document type definitions. While the change is persistent, it is not destructive (document types can be further modified or reverted through other means). The severity is high because modifying document types in a CMS affects content structure and rendering across the entire system, with broad impact on content management operations.

From the tool's definition Tool name 'update-document-type' and description 'Updates a document type by Id' indicate modification of document type definitions in Umbraco CMS.

RECOMMENDED RULE

The rule that runs update-document-type safely

update-document-type Rate-limited

update-document-type 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.
