## What it does

This plugin connects Claude Code to the AWS MCP Server and loads a curated set of skills. The server provides `search_documentation` and `retrieve_skill`, which fetch AWS reference material and skills without credentials. It also includes `run_script` for sandboxed Python execution.

Direct API access through `call_aws` reaches over 300 AWS services. This tool requires active credentials. Without valid AWS authentication, the agent can only query documentation. Included skills cover AWS CDK, CloudFormation deployments, serverless setups, and Amazon Bedrock models. The plugin also provides reviews across all six pillars of the Well-Architected Framework.

Recommended rule files are not applied automatically. You must pull them manually from the repository's `rules/` folder.
