Privacy policy

Last updated: 12 October 2026. Operated by the Autodesk MCPs administrator (contact: shady.hefilla@hotmail.com).

This policy covers both Revit MCP and Navisworks MCP, which share this service, and makes the same promises for both. For Navisworks MCP, read Navisworks wherever it says Revit (for example the Navisworks and Navisworks MCP version), and models, files and items wherever it says models, files and elements.

What is collected

• That Revit MCP is in use: when you signed in, when a Revit with Revit MCP was last running on your PC (it reports at start and once an hour), and the Revit and Revit MCP version, and whether the administrator has licensed your account. This shows the administrator who uses Revit MCP and who is active; it is never shown to other users and says nothing about your models.
• Missing-feature reports you agree to send: when Revit MCP cannot do something you asked, your AI assistant may offer to report it. Only if you agree, it sends what is missing, a description, and a summary of your request written without project, client or file names, with your account and the Revit version, so the developer can add it in a next version.
• Bug reports: when a Revit MCP tool fails because of a defect in Revit MCP itself (for example a file missing from its installation), Revit MCP reports it automatically: the tool, the error message and where in Revit MCP's own code it happened, with names, numbers, file paths and e-mail addresses removed, plus your account and the Revit and Revit MCP version. Your AI assistant may also offer to report a bug it notices; it sends that only if you agree. Never what you asked, the tool's inputs or anything from your model.
• At sign-in (Google or GitHub): your name, e-mail address and account identifier, so contributions can be attributed to you and access can be withdrawn. Your password is never seen: you enter it on Google's or GitHub's own page.
• While Revit MCP is used — AI-learning information only: which Revit MCP tool failed, its error message with names and numbers removed (e.g. Unknown category '…'), which option changed to make it work (generic words only, such as a Revit category like Walls; everything else is replaced by (text) or (number)), the Revit and Revit MCP version, advice the AI assistant wrote about using the tools, scripts that someone deliberately saved as reusable recipes, and playbooks (general step-by-step procedures for multi-step jobs, written without project names). Who wrote or used a playbook is never shown to other users.

What is not collected

No model or project information: no model, project, file or view names, no file paths, no element, level, type, sheet or parameter names or values, no geometry or drawings, no computer name, and none of the scripts the AI runs. This is removed on your PC before anything is sent, and the service removes it again on arrival.

Cloud AI access (optional, off unless you switch it on)

If you switch on Cloud AI access on your PC and add Revit MCP (or Navisworks MCP) as a connector in a cloud AI such as ChatGPT or claude.ai, that AI's requests and your PC's answers pass through this service on their way between the AI company and your PC. Those answers can contain model information, because that is what you ask the cloud AI to work with; the AI company handles it under its own privacy policy. This service only passes them on: it does not store or log their content. It keeps the list of tool names and descriptions your PC offers, and sign-in tokens for the connector (as one-way hashes, access tokens for one hour, refresh tokens for 90 days). Switch it off on your PC at any time; with it off, nothing passes.

What it is used for

Only to learn and increase the capabilities of Revit MCP for its users: merging repeated mistakes into lessons and offering known fixes and tips. The data is not sold, not used for advertising and not shared with anyone else.

Where it is kept

Contributions are stored in a private GitHub repository controlled by the administrator. Sign-in passes are kept by this service (Cloudflare) only as one-way hashes. Tips shown to other users carry no names.

Your choices

You can use Revit MCP without signing in (nothing is shared). You can sign out at any time (revit-mcp --logout, or navis-mcp --logout), and you can ask for your contributions to be removed by writing to shady.hefilla@hotmail.com.
