Why color_splash needs a policy

The description is empty, so the exact behavior cannot be determined from it. Based on the tool name 'color_splash' and the context of sibling tools (notably 'clear_colors'), this tool likely applies color highlighting/visualization to Revit model elements. This would be a Write-level operation (modifying visual properties), but without a description, confidence is low.

From the tool's definition Tool name is 'color_splash'; description is empty and uninformative.

POLICY

How to control color_splash

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP server for Revit - Python, and nothing reaches the server without passing your rules. This is the rule we recommend for color_splash:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "color_splash": {
      "limits": [
        {
          "counter": "color_splash_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

color_splash gets a rate cap, and everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
