AWS Cognito MCP Server

A Model Context Protocol (MCP) server implementation that connects to AWS Cognito for authentication and user management. This server provides a set of tools for user authentication flows including sign-up, sign-in, password management, and more.

Prerequisites

  • AWS account with Cognito User Pool configured
  • Node.js 18 or higher

Installation

# Clone the repository git clone https://github.com/yourusername/mcp-server-aws-cognito.git # Install dependencies cd mcp-server-aws-cognito npm install # Build the server npm run build

AWS Cognito Configuration

  1. Log in to your AWS Console and navigate to Amazon Cognito
  2. Create a User Pool or use an existing one
  3. Note your User Pool ID and App Client ID
  4. Set these values as environment variables or in a .env file (you need .env file only when you use claude code, not claude desktop):
AWS_COGNITO_USER_POOL_ID=your-user-pool-id AWS_COGNITO_USER_POOL_CLIENT_ID=your-app-client-id

The Inspector will provide a URL to access debugging tools in your browser.

Using with Claude Desktop

Before starting make sure Node.js is installed on your desktop for npx to work.

  1. Go to: Settings > Developer > Edit Config
  2. Add the following to your claude_desktop_config.json:
{ "mcpServers": { "aws-cognito-mcp-server": { "command": "/path/to/mcp-server-aws-cognito/build/index.js", "env": { "AWS_COGNITO_USER_POOL_ID": "your-user-pool-id", "AWS_COGNITO_USER_POOL_CLIENT_ID": "your-app-client-id" } } } }

Using with Claude Code

Claude Code is a command-line interface for Claude. To use this MCP server with Claude Code:

  1. Install Claude Code by following the instructions at Claude Code Documentation
  2. Add the MCP server to Claude Code:
claude mcp add "aws-cognito-mcp" npx tsx index.ts
  1. Verify it's been added:
claude mcp list
  1. Run Claude with your MCP server:
claude

Development

For development with auto-rebuild:

npm run watch

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. Use the MCP Inspector for better visibility:

npm run inspector

Now you can use the AWS Cognito authentication tools with Claude!
