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 | $0.00055 | $0.00332 |
| Opus 5 | $0.00028 | $0.00166 |
| Sonnet 5 | $0.00011 | $0.00066 |
| Haiku 4.5 | $0.00006 | $0.00033 |
Grade A, and why
enabling-lambda-vpc-internet-access 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.
What it actually says
Enabling Lambda VPC Internet Access
Overview
Domain expertise for enabling internet access from AWS Lambda functions running inside VPC private subnets. Lambda functions in a VPC cannot receive public IP addresses, so outbound internet access requires NAT Gateway infrastructure that routes traffic from private subnets through a public subnet to an Internet Gateway.
Enable internet access for a VPC Lambda function
To set up NAT Gateway infrastructure and configure routing for a Lambda function that needs internet access, follow the procedure exactly. See Lambda VPC internet access setup procedure.
Troubleshooting
NAT Gateway not working
Verify the route table associated with the Lambda subnets has a 0.0.0.0/0 route pointing to the NAT Gateway. See the full procedure for details.
Lambda function timeout
Check that security group outbound rules allow the necessary ports and that both the NAT Gateway and Internet Gateway are properly configured.
Network changes not taking effect
VPC networking changes can take 1–2 minutes to propagate. Wait before testing after creating a NAT Gateway or updating route tables.
Route table association issues
Confirm the Lambda function's subnets are associated with the route table that has the 0.0.0.0/0 route to the NAT Gateway.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

enabling-lambda-vpc-internet-access 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 55 tokens to every session and 332 once invoked, about $0.0003 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.
