WHAT IT DOES

What tag_walls does on Revit MCP Server

AI agents use tag_walls 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_walls is rated Medium

Based on the tool name and Revit context, 'tag_walls' likely creates annotation tags on wall elements, which is a Write operation (creating new annotation objects in the model). Confidence is low due to the empty description.

From the tool's definition Tool name 'tag_walls' with empty description. In Revit, tagging walls creates annotation tags attached to wall elements.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs tag_walls 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_walls, this is the rule to start with:

tag_walls Rate-limited

tag_walls 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.
