# 765T Flow

> AI for Autodesk Revit on Windows 10 or 11 (485 registered tools across 15 groups). Best supported on Revit 2021 and later. Every write lands inside one named undo step in Revit — one Ctrl+Z takes the whole write back. FLOW does not charge a fee during Early Access.

## What 765T Flow is

- No cloud builds your model for you. FLOW runs through a hosted endpoint and a connector on your machine, shows what a change would do when the call asks for a preview, and reports the result and the elements it changed afterwards.
- The assistant never talks to Revit directly. Between your prompt and the open model, the request goes through 765tflow.com/mcp and the FLOW add-in inside Revit — every Revit API call runs inside the Revit process on your machine.
1. The assistant you use: Sends a request over MCP to 765tflow.com/mcp. It does not know the Revit API — only the list of tools FLOW lets it see.
2. The 765tflow.com/mcp endpoint: 765tflow.com/mcp authenticates your signed-in account, checks the call against the declared tool surface, and sends the signed command down the live connection your Revit session opened.
3. The FLOW add-in inside Revit: Receives the signed command on the outbound connection it opened — nothing on your machine listens on a port — verifies the signature, and queues the work for a valid Revit API thread.
4. Your open Revit model: The add-in reads or edits the model on your machine; each write commits inside one named undo step (Ctrl+Z), and the RVT file never leaves your computer.
- 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.

## MCP endpoint

- URL: https://765tflow.com/mcp
- Transport: 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 API key or token sits in a configuration file.

## Seven hub tools (tools/list)

- 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.

## How to connect

### 1. Install Control Center on Windows
- The installer sets up Control Center and the add-in inside Revit for your Windows user only — no administrator rights are needed. Best supported on Revit 2021 and later.
1. Create a free account or sign in with Google or email on 765tflow.com, then click Download for Windows in your account. If your browser blocks the downloaded file: in Chrome, open Downloads and choose Keep; in Edge, hover the download, click the three dots → Keep → Show more → Keep anyway.
2. Run the installer (if you previously installed the 0.2 beta, uninstall it first). Because the installer is not digitally signed yet, Windows SmartScreen asks you to confirm on the first run: on the blue “Windows protected your PC” box, click More info — “Unknown publisher” is expected for an unsigned build — then click 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.

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

### 3. Connect Cursor
- With Cursor installed, click the button below — Cursor asks you to confirm, then adds the 765t-flow server.
- One-click install link: cursor://anysphere.cursor-deeplink/mcp/install?name=765t-flow&config=eyJ1cmwiOiJodHRwczovLzc2NXRmbG93LmNvbS9tY3AifQ==
- Or add this block to ~/.cursor/mcp.json yourself, then restart Cursor:
{
  "mcpServers": {
    "765t-flow": {
      "url": "https://765tflow.com/mcp"
    }
  }
}

### 4. Connect Antigravity
- Antigravity reads remote MCP servers from the serverUrl field in its raw MCP configuration (mcp_config.json):
- Official docs: https://antigravity.google/docs/mcp
1. Open mcp_config.json from the Antigravity IDE Agent side panel (… menu → MCP Servers → Manage MCP Servers → View raw config) or edit ~/.gemini/config/mcp_config.json directly.
2. Add the 765t-flow server entry under mcpServers and save the file:
3. Open Agent settings (Ctrl+, on Windows) → the Customizations tab, click Authenticate next to 765t-flow, and click "Authorize" in the browser.
4. After you click "Authorize", the browser lands on Antigravity's callback page (antigravity.google/oauth-callback) and shows a one-time OAuth authorization code. Copy that authorization code, paste it back into the Antigravity settings panel, and click Submit so the app on your PC receives the code from the browser and finishes connecting 765t-flow.
{
  "mcpServers": {
    "765t-flow": {
      "serverUrl": "https://765tflow.com/mcp"
    }
  }
}

Other apps with remote MCP over streamable HTTP and OAuth use this same address. 765T Flow writes nothing to any app's configuration on its own, and the Add to Cursor button adds the entry only when you confirm in Cursor.
