WHAT IT DOES

What tag_elements does on Revit MCP Server

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

RISK

Why tag_elements is rated Medium

Tagging elements in Revit is a metadata/annotation operation that modifies model content (tags are persistent annotations) but remains reversible—tags can be deleted or edited. This fits the Write category rather than Read (it modifies state) or Destructive (it can be undone).

From the tool's definition Tool name 'tag_elements' suggests adding or modifying tags on Revit elements. Within the Revit/BIM context alongside sibling tools like 'create_detail_line', 'create_dimensions', and 'create_duct', tagging elements represents a reversible modification…

RECOMMENDED RULE

The rule that runs tag_elements safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Revit MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tag_elements, this is the rule to start with:

tag_elements Rate-limited

tag_elements 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.

What risk level is tag_elements? +

tag_elements is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit tag_elements? +

Yes. Add a rate_limit block to the tag_elements rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block tag_elements completely? +
