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 | $0.00153 | $0.03190 |
| Opus 5 | $0.00077 | $0.01595 |
| Sonnet 5 | $0.00031 | $0.00638 |
| Haiku 4.5 | $0.00015 | $0.00319 |
Grade A, and why
querying-aws-s3 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.

Query AWS S3 System Tables
Overview
Works best with the AWS MCP server for sandboxed execution and audit logging. All commands below use the AWS CLI and work in any environment with configured AWS credentials. Use IAM roles or temporary credentials; avoid long-lived access keys.
Amazon S3 Metadata provides continuously-updated Apache Iceberg tables that capture
object-level metadata for general-purpose buckets. S3 Storage Lens exports aggregated
storage and activity metrics as Iceberg tables. Both are read-only, stored in the
AWS-managed aws-s3 table bucket, and queryable via Amazon Athena.
System tables are preferred over raw S3 APIs (list-objects-v2, head-object) because:
list-objects-v2paginates at 1000 objects/page — inefficient for large buckets (millions or billions of objects). The inventory table answersSELECT COUNT(*)in seconds at any scale.list-objects-v2cannot identify who uploaded an object, from which IP, or when something was deleted. Only the journal table hasrequester,source_ip_address, and delete event tracking.- Filtering by tag requires
get-object-taggingper object. The inventory table hasobject_tagsas a queryable map column.
Decision Tree
| User intent | Use this skill? | Table | Alternative |
|---|---|---|---|
| How many objects in my bucket | Yes | inventory | — |
| What was recently uploaded/deleted | Yes | journal | — |
| Who wrote/deleted objects (audit) | Yes | journal (requester, source_ip) | — |
| Storage class breakdown | Yes | inventory | — |
| Find objects by tag or user metadata | Yes | inventory | — |
| Search annotation content | Yes | annotation | Single object → direct API get-object-annotation |
| Write/update an annotation | No | — | Direct API: put-object-annotation (tables are read-only) |
| Query data inside objects | No | — | querying-data-lake |
| Bucket-level storage metrics/trends | Yes | Storage Lens tables | — |
| Enable metadata tracking | Yes | see Enable section | — |
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.

querying-aws-s3 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 153 tokens to every session and 3,190 once invoked, about $0.0008 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.
