Your AI can already see the screen. It just can't measure it. Screenshots make an agent guess: "that heading looks a bit faint. It runs locally over stdio via the published package.

People who work with accessibility, devtools and playwright and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Uisight

before you install - you'll need

UISIGHT_TOOLS

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add sololabstr-uisight -- npx -y uisight

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "sololabstr-uisight": {
      "command": "npx",
      "args": [
        "-y",
        "uisight"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)
