Store or update room metadata for a specific Revit project in the local database. Rooms are linked to a project by project name. The project must exist before storing room data.
AI agents use store_room_data to create or update resources in Revit — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Revit environment.
This tool creates or modifies room metadata in a local database, which is a reversible write operation. It does not delete data, execute code, or involve financial transactions. The blast radius is medium since incorrect room data could affect BIM project accuracy but can be corrected.

Attacks that exploit this kind of access
Store or update room metadata for a specific Revit project in the local database. Rooms are linked to a project by project name. The project must exist before storing room data. It is categorised as a Write tool in the Revit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Revit MCP server in PolicyLayer and add a rule for store_room_data: 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. Nothing to install.
store_room_data 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 store_room_data 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 store_room_data. 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.
store_room_data is provided by the Revit MCP server (mohamed-elnahla/revit-mcp-github-copilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
