Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Overview

A Model Context Protocol (MCP) server implementation that provides running generated python code to query any AWS resources through boto3.

At your own risk: I didn't limit the operations to ReadyOnly, so that cautious Ops people can be helped using this tool doing management operations. Your AWS user role will dictate the permissions for what you can do.

Why Another AWS MCP Server?

I tried AWS Chatbot with Developer Access. Free Tier has a limit of 25 query/month for resources. Next tier is $19/month include 90% of the features I don't use. And the results are in a fashion of JSON and a lot of restrictions.

I tried using aws-mcp but ran into a few issues:

  1. Setup Hassle: Had to clone a git repo and deal with local setup
  2. Stability Issues: Wasn't stable enough on my Mac
  3. Node.js Stack: As a Python developer, I couldn't effectively contribute back to the Node.js codebase

So I created this new approach that:

  • Runs directly from a Docker image - no git clone needed
  • Uses Python and boto3 for better stability
  • Makes it easy for Python folks to contri

Questions

What is the Aws Resources MCP server?

A Python-based MCP server that lets Claude run boto3 code to query and manage AWS resources. Execute powerful AWS operations directly through Claude with proper sandboxing and containerization. No need for complex setups - just pass your AWS credentials and start interacting with all AWS services.

What tools does Aws Resources expose?

1 in total: 0 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Aws Resources safe to connect to an agent?

No — not without reading the findings first. The audit graded it D (69/100) and found 1 critical or high issue in the source. Each one is listed on this page with the file and line it is on.

What credentials does Aws Resources need?

It reads AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_SESSION_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Aws Resources run?

It speaks stdio, so it runs as a local process your client starts. It is published on PyPI as mcp-server-aws-resources.

How current is this page?

The grade is for one exact copy of the source (8777dab1ad13), read on 2026-10-09. The repository is watched and re-audited when it changes.
