Using with Claude Desktop
Before starting make sure Node.js is installed on your desktop for npx to work.
Go to: Settings > Developer > Edit Config
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:
Install Claude Code by following the instructions at Claude Code Documentation
Add the MCP server to Claude Code:
claude mcp add "aws-cognito-mcp" npx tsx index.ts
- Verify it’s been added:
claude mcp list
- 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!
