WHAT IT DOES

What create_pipe does on Revit MCP Server

AI agents use create_pipe 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_pipe is rated Medium

Creating pipes in a Revit model modifies the architectural/MEP design document by adding new geometry and elements. This is reversible (pipes can be deleted), so it falls under Write rather than Destructive. While the description is empty, the tool name combined with the server's MEP focus and sibling tool patterns strongly indicate data creation.

From the tool's definition Tool name 'create_pipe' indicates creation of MEP (mechanical, electrical, plumbing) piping elements in Revit.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_pipe Rate-limited

create_pipe 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.

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about create_pipe

What does the create_pipe tool do? +

create_pipe 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 create_pipe? +

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

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

Can I rate-limit create_pipe? +

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

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

create_pipe 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.
