WHAT IT DOES

What ai_element_filter does on Revit MCP Server

AI agents call ai_element_filter 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 ai_element_filter is rated Low

With an empty description, classification relies on the tool name. 'Filter' strongly implies a read/query operation — selecting or retrieving a subset of elements from the Revit model. No side effects are implied by the name alone. Confidence is lowered due to the absence of a description.

From the tool's definition Tool name 'ai_element_filter' and empty description. The name suggests filtering/querying elements in a Revit model.

RECOMMENDED RULE

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

ai_element_filter Allowed

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

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

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 ai_element_filter call is checked against it from then on.
