WHAT IT DOES

What create_dimensions does on Revit MCP Server

AI agents use create_dimensions 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 create_dimensions is rated Medium

The tool creates (adds) dimensional annotations to a Revit model, which is a reversible modification of project data. This falls under Write rather than Execute because it modifies structured design data rather than executing arbitrary code. While the empty description reduces confidence from near-certain to high, the naming convention and server context strongly indicate a data-creation operation.

From the tool's definition Tool name 'create_dimensions' on a Revit MCP server context with sibling tools like 'create_detail_line', 'create_duct', 'create_grid', 'create_level' that all perform reversible data creation operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_dimensions Rate-limited

create_dimensions 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_dimensions call is checked against it from then on.
