Connect an AI app to Revit with 765T Flow

MCP endpoint

Every AI app points at the same address, over streamable HTTP:

Authentication is OAuth 2.1 with PKCE in the browser: the first connect opens a 765T Flow page and you click "Authorize" once. No code is typed or pasted.

Seven hub tools

These are what an AI app sees in tools/list. The 468 Revit tools in the catalog are opened through flow_tools and run through flow_call.

• flow_list_instances

  Lists the account's connected Revit instances and their open documents, and returns the instanceId every catalog call needs.

• flow_read_result

  Reads the next part of a long answer, exactly as that answer's next pointer names it.

• flow_report_issue

  Sends a bug report, feedback or a feature request to the 765T Flow team when you ask for it, and returns a reference id.

• flow_tools

  Browses the catalog: the tool groups, one group's members, or one tool's exact input schema.

• flow_call

  Runs one catalog tool by its exact name, with arguments in the schema flow_tools returned.

• flow_find

  Finds the right tool or how-to guide for a Revit job described in plain words. Read-only.

• flow_get

  Reads one guide or tool entry in full, by the ref flow_find returned. Read-only.

flow_find and flow_get are listed when the hosted guide library is available.

How a write runs

The assistant you connected decides — no approval dialog sits in between.

• Preview is optional: for a tool that supports a dry run, the call sets dryRun to check first without touching the model.
• Every write lands inside one named undo step in Revit — one Ctrl+Z takes the whole write back.
• After the write, the tool reports the execution result and the list of elements it changed.
• A write whose outcome is uncertain is never blindly retried.

Install Control Center on Windows

The installer sets up Control Center and the connector inside Revit for your Windows user only — no administrator rights are needed.

1. Create a free account or sign in on 765tflow.com — the installer lives in your account.

2. Download the Windows installer and run it. If Windows SmartScreen appears, click More info, then Run anyway.

3. Open Revit. When Revit asks about the 765T Flow add-in, choose Always Load.

Then pair the Revit side with your account:

1. Open 765T Flow Control Center.

2. Press "Sign in" on the account strip.

3. The browser opens this very site — click "Authorize" once. The card updates itself when the account is accepted.

Connect Claude, ChatGPT or Cursor

Each app adds the same MCP address; the first connect opens the browser for your "Authorize" click.

Claude

1. In Claude — on the web or in the desktop app — open "Customize > Connectors".

2. Click "+", then "Add custom connector", and paste this address:

   https://765tflow.com/mcpCopy

3. Click "Add" — the browser asks for "Authorize" once, and that is all it asks.

ChatGPT

1. In ChatGPT on the web, open Settings → Security and login and turn on Developer mode.

2. Add a connector with this address:

   https://765tflow.com/mcpCopy

3. Finish with one "Authorize" click in the browser.

Cursor

With Cursor installed, click the button below — Cursor asks you to confirm, then adds the 765t-flow server.

Add to Cursor

Or add this block to ~/.cursor/mcp.json yourself, then restart Cursor:

{
  "mcpServers": {
    "765t-flow": {
      "url": "https://765tflow.com/mcp"
    }
  }
}

Another app with remote MCP support over streamable HTTP and OAuth uses this same address. 765T Flow writes nothing into any app's configuration.

Check the connection

Ask the assistant to call flow_list_instances. The answer lists your connected Revit instances; an empty list means no connector is online yet — open Control Center, press "Sign in" and start Revit.
