Agent Toolkit for AWS

Help AI coding agents build, deploy, and manage applications on AWS.

The Agent Toolkit for AWS gives AI coding agents the tools, knowledge, and guardrails they need to work with AWS services. It works with the coding agents developers already use — including Claude Code, Codex, Cursor, Devin, Kiro, and fx.

Quick start

AWS CLI

Use the Agent Toolkit directly from your terminal with the AWS CLI:

aws configure agent-toolkit

See the AWS CLI integration guide for setup, configuration, and usage instructions.

Claude Code

The plugins are available on the official Anthropic marketplace (claude-plugins-official) which is added to your Claude Code installation by default. Use the following commands to install supported plugins from the toolkit:

For aws-core that covers service selection, CDK/CloudFormation, serverless, containers, storage, observability, billing, SDK usage, and deployment:

/plugin install aws-core@claude-plugins-official

Tip: If you get Plugin not found, update your local marketplace index first:

/plugin marketplace update claude-plugins-official

For aws-agents that covers building AI agents on AWS with Amazon Bedrock and AgentCore:

/plugin install aws-agents@claude-plugins-official

For aws-data-analytics that covers data lake, analytics, and ETL workflows with S3 Tables, AWS Glue, and Athena:

/plugin install aws-data-analytics@claude-plugins-official

For aws-agents-for-devsecops used to investigate incidents, review code and execute UAT for release readiness, scan code for vulnerabilities, and run penetration tests with AWS DevOps Agent and AWS Security Agent.

/plugin marketplace add aws/agent-toolkit-for-aws
/plugin install aws-agents-for-devsecops
/reload-plugins

# Or from Claude's official marketplace:
/plugin install aws-agents-for-devsecops@claude-plugins-official
/reload-plugins

# Setup:
/aws-agents-for-devsecops:setup

For aws-startup-advisor that covers startup-focused architecture, cost, security, and AWS Activate guidance, plus migrations to AWS from Azure, GCP, Heroku, and AI stacks such as OpenAI and Gemini, install from this repository's marketplace:

/plugin marketplace add aws/agent-toolkit-for-aws
/plugin install aws-startup-advisor@agent-toolkit-for-aws
/reload-plugins

Codex

In your terminal:

codex plugin marketplace add aws/agent-toolkit-for-aws

Then launch Codex and run /plugins to browse and install the aws-core plugin.

Cursor

Add this repository as a team marketplace from Settings → Plugins → Team Marketplaces → Add Marketplace → Import from Repo, pointing it at aws/agent-toolkit-for-aws. Cursor indexes the plugins listed in .cursor-plugin/marketplace.json on import.

Then open the Plugins panel and install the aws-core plugin (start here), or aws-agents and aws-data-analytics as needed. Each plugin bundles the AWS MCP Server configuration and agent skills.

Devin

In your terminal:

devin plugins install aws/agent-toolkit-for-aws#plugins/aws-core

This requires devin auth login and adds the plugin to your personal plugins, so it also loads in Devin cloud sessions and Devin Desktop. Add --local to install on this machine only. To install a different plugin, replace aws-core with its name from Plugins, such as aws-agents or aws-data-analytics.

In the Devin web app, choose Customize → Plugins → Add plugin → From repository, enter aws/agent-toolkit-for-aws, and set the subdirectory to plugins/aws-core (or another plugin's directory). Personal plugins added there are also available in the Devin CLI and Devin Desktop.

Kiro

Kiro setup has two independent parts: the AWS MCP Server (for runtime AWS API access and documentation search) and local skills (for task-specific agent guidance). They complement each other but work independently — skills don't require the MCP server, and the MCP server doesn't serve locally-installed skills.

1. Add the AWS MCP Server to your Kiro MCP configuration (.kiro/settings/mcp.json):

{
  "mcpServers": {
    "aws": {
      "command": "uvx",
      "args": [
        "mcp-proxy-for-aws-cli@latest",
        "https://aws-mcp.us-east-1.api.aws/mcp",
        "--metadata",
        "AWS_REGION=us-west-2"
      ]
    }
  }
}

The MCP server gives your agent access to AWS APIs, sandboxed script execution, and real-time documentation search.

2. Install skills from this repository:

npx skills add aws/agent-toolkit-for-aws/skills

This installs skill files to ~/.kiro/skills/ (global) or .kiro/skills/ (project-level). Each skill is a directory containing a SKILL.md file and optionally a references/ subdirectory with additional context the agent reads from the local filesystem when needed. Kiro discovers installed skills automatically and activates them on demand when a task matches.

Prerequisites: You need uv installed. An AWS account with credentials configured locally is required for API calls and script execution, but not for documentation search or skill discovery. See the user guide for detailed setup instructions.
