WHAT IT DOES

What clear_colors does on Revit MCP Server

AI agents use clear_colors 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 clear_colors is rated Medium

The description is empty, lowering confidence. Based on the name and context of the 'color_splash' sibling tool (which likely applies colors to elements), 'clear_colors' most likely reverses or removes color overrides from Revit elements or views. This is a reversible modification (colors can be reapplied), placing it in the Write category.

From the tool's definition Tool name 'clear_colors' and sibling tool 'color_splash' suggest this removes color overrides applied to elements in a Revit view.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

clear_colors Rate-limited

clear_colors 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.
