"mcpServers": {
"hello-mcp": {
"command": "npx",
"args": ["tsx", "/Users/mingfang/Code/hello-mcp/index.ts"]
}
}
}
Deploy to AWS Lambda
# Build and deploy
npm run deploy
# Or step by step
npm run build:lambda
sam deploy --guided
First time setup:
🔑 Authentication
Bearer token: mcp-secret-token-12345
Change it:
sam deploy --parameter-overrides BearerToken="your-new-token"
🧪 Test Deployment
# Health check
curl https://gjt4ggcz76.execute-api.ap-southeast-2.amazonaws.com/health
# List available tools
curl -H "Authorization: Bearer mcp-secret-token-12345" \
https://gjt4ggcz76.execute-api.ap-southeast-2.amazonaws.com/mcp
# Call sayHello tool
curl -X POST \
-H "Authorization: Bearer mcp-secret-token-12345" \
-H "Content-Type: application/json" \
-d '{"tool": "sayHello", "params": {"name": "World"}}' \
