Agent Toolkit for AWS is a collection of AWS-supported MCP servers, skills, plugins, commands, and hooks that help AI coding agents build, deploy, and manage applications on AWS. It is used by developers working with AWS services through agents such as Claude Code, Codex, Cursor, and Kiro. The catalogue entries are the toolkit's own agent extensions for AWS development and operations.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00211 | $0.02035 |
| Opus 5 | $0.00105 | $0.01018 |
| Sonnet 5 | $0.00042 | $0.00407 |
| Haiku 4.5 | $0.00021 | $0.00203 |
Grade A, and why
waf scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

AWS WAF
Overview
Domain expertise for configuring AWS WAF, the web application firewall that filters HTTP and HTTPS traffic to CloudFront distributions, Application Load Balancers, API Gateway REST APIs, and AppSync GraphQL APIs. Covers web ACL creation and association, AWS Managed Rules, rate-based rules, match rules (IP set and geographic), Bot Control and the signal-forwarding workflows built on top of it, Fraud Control for logins and signups, AI and LLM crawler management, and the logging that every tuning workflow depends on.
This skill is a router. Each customer task maps to a procedure file under references/. Read the
matching reference in full before acting, then follow its constraints and steps. The reference
files are self-contained: each carries its own decision tables, constraints, procedure, and
troubleshooting.
Execute commands using the AWS MCP server when connected (sandboxed execution, audit logging,
observability). Fall back to the AWS CLI otherwise. A web ACL's scope is fixed at creation: a
CloudFront web ACL must be created in us-east-1 with CLOUDFRONT scope, while a regional web ACL
(Application Load Balancer, API Gateway, AppSync) is created in the resource's Region with
REGIONAL scope.
Which WAF task do you need?
| Goal | Reference |
|---|---|
| Create a web ACL and attach it to a resource | creating a web ACL and associating it with a resource |
| Set up logging and sampling before tuning anything | setting up logging and request sampling |
| Add AWS Managed Rules and tune false positives | adding managed rules and tuning with count mode |
| Throttle HTTP floods and brute force | adding rate-based rules |
| Allow or block by IP range or country | using ip sets and geographic match rules |
| Detect and control bots (the on-ramp) | protecting against bots with bot control |
| Collapse bot labels into one confidence signal | turning bot control labels into a confidence signal |
| Forward all signals to the origin with one rule | forwarding signals with dynamic label interpolation |
| Decide what the app does with the forwarded signal | adaptive mitigation playbook for forwarded signals |
| Stop attackers from spoofing forwarded headers | stripping inbound waf headers before trusting them |
| Recover the real client IP behind a CDN | recovering the real client ip behind a cdn |
| Protect logins and signups from fraud | protecting logins and signups with fraud control |
| See and manage AI and LLM crawler traffic | seeing and managing ai crawler traffic |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

waf is a skill published in the GitHub repository aws/agent-toolkit-for-aws (2,569 stars, last pushed yesterday), licensed Apache-2.0. It adds 211 tokens to every session and 2,035 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
