WHAT IT DOES

What link_file does on Revit MCP Server

AI agents use link_file 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 link_file is rated Medium

The empty description limits confidence, but in Revit's context, 'link_file' most likely creates or modifies the model structure by linking external files (a common Revit operation). This is a Write action (reversible via unlinking) rather than Execute or Destructive.

From the tool's definition Tool name 'link_file' suggests linking external files into a Revit model, which is a reversible write operation that modifies the project by adding references or dependencies.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

link_file Rate-limited

link_file 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 link_file call is checked against it from then on.

Questions about link_file

What does the link_file tool do? +

link_file 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 link_file? +

Register the Revit MCP Server MCP server in PolicyLayer and add a rule for link_file: 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 link_file? +

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

Can I rate-limit link_file? +

Yes. Add a rate_limit block to the link_file 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 link_file completely? +

Set action: deny in the PolicyLayer policy for link_file. 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 link_file? +

link_file 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.
