What create_room_separation does on Revit MCP Server
AI agents use create_room_separation 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.
Why create_room_separation is rated Medium
The tool creates new model elements (room separations) in a Revit project, which is a reversible modification operation. This is Write rather than Execute because it performs a specific creation action with predictable effects, not arbitrary code execution. The empty description lowers confidence slightly, but the naming pattern and sibling context strongly indicate element creation.
From the tool's definition Tool name 'create_room_separation' indicates creation of architectural elements in Revit (room separation lines/boundaries).
Attacks that exploit this kind of access
The rule that runs create_room_separation 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 create_room_separation, this is the rule to start with:
create_room_separation 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 create_room_separation call is checked against it from then on.
Questions about create_room_separation
create_room_separation 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.
Register the Revit MCP Server MCP server in PolicyLayer and add a rule for create_room_separation: 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.
create_room_separation is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_room_separation 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.
Set action: deny in the PolicyLayer policy for create_room_separation. 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.
create_room_separation 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.
