Michael Walmsley has developed an MCP (Model Context Protocol) server that enhances LLMs (like Claude) to search through AWS Lambda Powertools documentation efficiently. This server supports multiple runtimes:
– Python
– TypeScript
– Java
– .NET
🔗 GitHub Project: https://github.com/serverless-dna/powertools-mcp
Key Features:
✔ Local document index search (mirroring Powertools’ official search)
✔ Live webpage scraping (`fetch_doc_page` for real-time context)
✔ Multi-runtime support (Python, TS, Java, .NET)
✔ Compatible with Claude & MCP-based LLMs
You Should Know: How to Deploy & Use Powertools MCP Server
1. Clone & Set Up the Repository
git clone https://github.com/serverless-dna/powertools-mcp.git cd powertools-mcp pip install -r requirements.txt Python dependencies
2. Run the MCP Server Locally
python server.py --port 5000
(Replace `5000` with your preferred port.)
3. Integrate with Claude or Other LLMs
Configure your LLM to use the MCP endpoints:
- Search Docs: `POST /search_docs` (query: string)
- Fetch Page: `POST /fetch_doc_page` (url: string)
Example cURL for testing:
curl -X POST http://localhost:5000/search_docs -H "Content-Type: application/json" -d '{"query": "Lambda layers"}'
4. AWS Deployment (Optional)
Deploy using AWS SAM or Serverless Framework:
template.yaml (SAM)
Resources:
MCPFunction:
Type: AWS::Serverless::Function
Properties:
CodeUri: powertools-mcp/
Handler: server.lambda_handler
Runtime: python3.9
Events:
ApiEvent:
Type: Api
Properties:
Path: /{proxy+}
Method: ANY
What Undercode Say
The Powertools MCP Server bridges the gap between LLMs and AWS documentation, ensuring real-time accuracy. Below are essential commands for AWS Lambda & Powertools:
AWS CLI & Lambda Commands
List Lambda functions
aws lambda list-functions
Deploy a Lambda layer
aws lambda publish-layer-version --layer-name "powertools-layer" --zip-file fileb://layer.zip
Update Lambda environment variables
aws lambda update-function-configuration --function-name MyFunction --environment "Variables={KEY=value}"
Python Powertools Snippet
from aws_lambda_powertools import Logger, Tracer
logger = Logger()
tracer = Tracer()
@tracer.capture_lambda_handler
def handler(event, context):
logger.info("Processing event")
return {"statusCode": 200}
Linux/DevOps Commands
Monitor Lambda logs aws logs tail /aws/lambda/MyFunction --follow Install Powertools for Python pip install aws-lambda-powertools Check running processes (Linux) ps aux | grep python
Expected Output:
A fully functional MCP server that supercharges LLMs with AWS Lambda Powertools docs, reducing outdated responses and improving accuracy. 🚀
