Show HN: AWS MCP – Talk with Your AWS from Claude Using Model Context Protocol

rwilinski — Wed, 18 Dec 2024 12:33:23 +0000

Author here. I built this after getting frustrated with Amazon Q and wanting a more developer-friendly way to interact with AWS infrastructure. It's a local MCP server that lets Claude safely access your AWS environment using your existing local credentials.

I've tried it on cases like: - Visualize my networking setup - Prepare a thorough analysis of my AWS costs and give insights how to cut it - Find S3 buckets without encryption enabled and their total size

And it works surprisingly well. Let me know what do you think!

Show HN: Claude and Apple Notes integration using MCP

rwilinski — Mon, 16 Dec 2024 18:37:38 +0000

Hi all,

With MCP (Model Context Protocol) announcement, it is now possible to plugin local system to Claude. So, I decided to use JXA to pull content from Notes.app, turn them into embeddings locally/on device using Transformer.js and store them in a local LanceDB database so we can build a proper RAG on top of it (mixture of semantic and BM25 search).

Hope some of you find it useful!

Building AI agents is hard. Most attempts end up with brittle systems that break in production, cost too much to run, or worse - make costly mistakes that could have been prevented.

Fortunately, there are several core principles that I’ve learned while building agents that actually work. Hope you find it useful!

Show HN: Talk to Your AWS Cloud

Hey HN,

Just launched ChatWithCloud, a Terminal CLI tool for chatting with AWS. It lets you manage AWS resources using natural language commands - think of it as chatting with AWS to get things done.

Keen to hear what do you think.

Thanks, R

I made Dynobase [1], an alternative GUI for DynamoDB. Passed 2k/mo few years ago. Runs 100% automatically now, I spend ~2h/week mostly responding to customer inquiries. I could leave my full time job but I just like it (and money) too much.

New comment by rwilinski in "AWS IAM Manager – Users, Groups, Policies as a Code with one simple Lambda"

rwilinski — Mon, 26 Dec 2016 10:36:55 +0000

That's pretty good idea, I haven't thought about it.

I think that my format is easier to understand. You don't have to use `Ref`s and weird `Fn::Join`s which may be not obvious for developers which are not experienced with CF.
