Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

NPM package uivision-mcp-bridge
Claude Code 
claude mcp add ui-vision-mcp -e 'UIVISION_MCP_PORT=<UIVISION_MCP_PORT>' -- npx -y uivision-mcp-bridge@1.7.18

Ui.Vision - Browser and Desktop Automation

Automate websites and desktop applications with macros, JavaScript, or an AI assistant. Ui.Vision combines browser automation, OCR and image recognition, with an MCP server that lets AI agents create, edit and run reusable macros in your browser.

What can you automate?

  • Browser tasks: fill forms, extract web data, download reports and repeat workflows in your existing browser session.
  • Website testing: record and replay interactions, use Selenium IDE commands, and run checks with different input data.
  • Visual tasks: find on-screen text with OCR and locate controls by image when HTML selectors are unavailable.
  • Desktop workflows: automate applications and remote desktop interfaces using visual recognition and mouse and keyboard input. Desktop automation requires the additional Ui.Vision desktop components (XModules).
  • AI-assisted automation: ask the built-in AI assistant or an external MCP client to write and run macros, then inspect the resulting script, logs and screenshots.

Use the macro recorder and command table, write JavaScript with the uiv.* API, or let an AI assistant author the macro. The resulting automation can be saved and run again.

Get started

Install the browser extension; you do not need to build this repository:

Open Ui.Vision and record a browser task, or start with a macro from the extension's demos. For desktop input and additional native capabilities, see the XModules installation guide.

The browser extension is open source and free for personal and commercial use. See the Ui.Vision website for desktop components and available editions.

Connect an AI assistant with MCP

Ui.Vision provides a Model Context Protocol (MCP) server through the uivision-mcp-bridge package. It connects MCP clients such as Claude Code, Claude Desktop and Cursor to the Ui.Vision browser extension.

An agent can inspect a page, create or edit a macro, run it, and use logs and screenshots to check the result. The automation executes through Ui.Vision in your browser.

Start with the MCP setup guide. The installer command is:

npx uivision-mcp-bridge --setup

The installer registers Ui.Vision with supported MCP clients found on your machine. Then enable the MCP bridge in Ui.Vision → Settings → AI, complete the connection steps in the guide, and restart your MCP client. Node.js and npm are required to run the installer.

For a first task, ask your connected assistant:

Use Ui.Vision to open https://example.com, read the page heading, and save a reusable macro for this task.

See mcp/README.md for bridge source, configuration and troubleshooting.

JavaScript automation and documentation for AI assistants

The uiv.* JavaScript API covers page elements, visual matching, OCR, browser and desktop input, screenshots, tabs, CSV files and downloads. Ui.Vision macros execute sequentially: write API calls without async or await.

When asking an AI assistant to write a macro, give it the API reference below so it uses Ui.Vision's supported methods and runtime conventions.

Help and support

Ask questions and share automation examples in the Ui.Vision user forum, where users, support staff and developers participate.

Build from source

Building the extension is not required if you "only" want to use it.

You can install UI.Vision directly from the Chrome, Edge or Firefox stores, which is the easiest and the recommended way of using the Ui.Vision browser extension. Older versions can be found in the RPA software archive.

The information below is only required and intended for developers:

The project uses Node V20.11.1 and NPM V10.2.4

If you have any questions, please contact us at TEAM AT UI.VISION - Thanks!

Build the extension bundle
npm i -f
npm run build
npm run build-ff

npm run build creates the Chrome/Edge build in dist, npm run build-ff creates the Firefox build in dist_ff.

Develop
npm i -f
npm start

Use npm run start-ff for the Firefox variant. Both run webpack in watch mode, so the bundles in dist (Chrome/Edge) and dist_ff (Firefox) are rebuilt on every change.

Once done, the ready-to-use extension code appears in the /dist directory (Chrome, Edge) or /dist_ff directory (Firefox). Load it via chrome://extensions → "Load unpacked" (Chrome/Edge) or about:debugging → "Load Temporary Add-on" (Firefox).

Repository layout

  • src/ - the extension source (React UI, side panel, macro player, commands)
  • extension/ - static extension assets and manifest.json (Manifest V3)
  • mcp/ - the Ui.Vision MCP bridge, which lets Claude Code and other MCP clients create, edit and run macros. See mcp/README.md
  • dist/, dist_ff/ - build output for Chrome/Edge and Firefox
