Overview

What is Local Scanner MCP Server?

Local Scanner MCP Server is a Model Context Protocol (MCP) server that enables AI assistants to scan local code and localhost URLs. It provides tools for validating code style, capturing screenshots of local web pages, analyzing console logs, and checking HTML compliance. It is designed for developers using AI assistants like Cline (VSCode) or Cascade (WindSurf) to interact with local development environments.

How to use Local Scanner MCP Server?

Install dependencies with npm install, build with npm run build, and start with npm start. Then configure an MCP client (e.g., for Cline or WindSurf) by editing the respective settings file and providing the path to the built server (build/index.js). The server exposes four tools: scan_localhost, screenshot_localhost, lint_code, and validate_html.

Key features of Local Scanner MCP Server

  • Access and scan localhost URLs for runtime errors
  • Capture full-page or partial screenshots of local web pages
  • Lint JavaScript, TypeScript, and CSS files
  • Validate HTML content or URLs for standards compliance
  • Perform automated page interactions (click, type, wait)
  • Integrates seamlessly with MCP AI assistant clients

Use cases of Local Scanner MCP Server

  • Debugging locally running web applications with an AI assistant
  • Visually verifying frontend changes via screenshots
  • Enforcing code quality by linting files during development
  • Ensuring web pages meet HTML accessibility standards
