An MCP (Model Context Protocol) server for accessibility checking and rule validation. This tool scans TypeScript files for common accessibility and code quality violations.

Installation

Install the package globally or locally:

npm install -g accessibility-mcp

Or install locally in your project:

npm install accessibility-mcp

Configuration

Add the following to your mcp.json configuration file (used by Cursor, Copilot, and other MCP-compatible tools):

Global Installation

{
  "mcpServers": {
    "accessibility": {
      "command": "node",
      "args": [
        "/path/to/global/node_modules/accessibility-mcp/build/index.js"
      ]
    }
  }
}

Local Installation

{
  "mcpServers": {
    "accessibility": {
      "command": "node",
      "args": [
        "./node_modules/accessibility-mcp/build/index.js"
      ]
    }
  }
}

Using npx (Recommended)

{
  "mcpServers": {
    "accessibility": {
      "command": "npx",
      "args": [
        "accessibility-mcp"
      ]
    }
  }
}
