WHAT IT DOES

What export_ifc does on Revit MCP Server

AI agents use export_ifc 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 export_ifc is rated Medium

The tool exports architectural/BIM data from Revit to IFC format, creating a new file or overwriting an existing export. This is a Write operation (creates/exports data) rather than Read (it produces persistent output). Severity is high because exported IFC files could be shared externally, potentially exposing sensitive building information or design details, and incorrect exports could affect downstream workflows.

From the tool's definition Tool name is 'export_ifc', which exports model data to IFC (Industry Foundation Classes) format. This is a write/output operation that serializes and exports building model data to an external file.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

export_ifc Rate-limited

export_ifc 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.

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

FAQ

Questions about export_ifc

What does the export_ifc tool do? +

export_ifc is a write tool on the Revit MCP Server MCP server. It is categorised as a Write tool in the Revit MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on export_ifc? +

Register the Revit MCP Server MCP server in PolicyLayer and add a rule for export_ifc: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Revit MCP Server. Nothing to install.

What risk level is export_ifc? +

export_ifc is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit export_ifc? +

Yes. Add a rate_limit block to the export_ifc rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block export_ifc completely? +

Set action: deny in the PolicyLayer policy for export_ifc. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides export_ifc? +

export_ifc is provided by the Revit MCP Server MCP server (demolinator/revit-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
