WHAT IT DOES

What check_clashes does on Revit MCP Server

AI agents call check_clashes to retrieve information from Revit MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why check_clashes is rated Low

Clash detection is a model analysis operation that checks for intersections or conflicts between MEP systems or structural elements. It reads and analyzes model geometry without modifying data, making it a Read operation.

From the tool's definition Tool name 'check_clashes' suggests it performs clash detection analysis within a Revit model, comparing geometric elements for conflicts. The description is empty, which limits definitive classification.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

check_clashes Allowed

check_clashes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "check_clashes": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Revit MCP Server, apply this rule, and every check_clashes call is checked against it from then on.
