WHAT IT DOES

What save_document does on Revit MCP Server

AI agents use save_document 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 save_document is rated Medium

Saving a document in Revit commits design changes, model data, and metadata to disk. This is a write operation with substantial impact—unsolicited saves could overwrite important project versions or interrupt collaborative workflows. However, it's reversible via undo/version control, so it ranks below Destructive.

From the tool's definition Tool name 'save_document' indicates it persists changes to a Revit project file. Empty description limits specificity, but the function clearly modifies persistent state by writing to the document.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

save_document Rate-limited

save_document 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 save_document call is checked against it from then on.
