Use AWS MCP Server

What it is

A standalone Rust server that reproduces the use_aws tool from the Amazon Q Developer CLI so any MCP client can have it. One tool takes a service, an operation and its parameters, formats them for the CLI, runs the command and returns the output — with parameter names converted to kebab-case and a human-readable description of what is about to run.

What you get

• use_aws — call any AWS CLI operation, with service_name, operation_name and region required, and optional parameters, profile_name and label
• An automatic read-only check based on the operation prefix: get, describe, list, ls, search and batch_get run without ceremony, and everything else is treated as a write requiring explicit user acceptance
• A readable rendering of the command before it runs — service, operation, parameters, profile, region and label — so what is about to happen is visible rather than buried in a JSON blob
• Output truncation with a maximum response size of 100KB, so a large listing does not swamp the context

Requirements

AWS CLI installed and configured, and AWS credentials available through the CLI, environment variables or an IAM role. Rust 1.70 or later and Cargo; install with cargo install use_aws_mcp and point the client at the use_aws_mcp command over stdio, with a generous timeout. Non-shell clients such as Cursor do not inherit your shell environment, so name the profile explicitly on each call — the README's advice is to tell the client which profile to use rather than relying on AWS_DEFAULT_PROFILE being present.

Setup effort

One command plus credentials — cargo install use_aws_mcp, then supply credentials
