01 · Install Corralimited MCP Server

before you install - you'll need

SNAPDIFF_API_KEY

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

Claude Code

claude mcp add corralimited-snapdiff-mcp -- npx -y @corralimited/snapdiff-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "corralimited-snapdiff-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@corralimited/snapdiff-mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

The 4 tools it gives your agent

Extracted from the project's README - what mcp lets an agent do.

snapdiff_verify_ui_change: - Checks whether a visual change matches the agent's stated intent. Returns verdict (pass / expected_change_detected / unexpected_regression / no_change_detected
snapdiff_compare_pages: - Raw visual diff between two URLs, or a URL vs. a stored project baseline. Use for ad-hoc diffs that don't fit the verify-ui-change verdict shape.
snapdiff_capture_screenshot: - Single screenshot of a URL.
snapdiff_html_to_image: - Render HTML/CSS to an image (OG cards, social images, email headers).
