What it does

Enabling Lambda Vpc Internet Access is an agent skill from aws/agent-toolkit-for-aws, published by the product's own GitHub organization. Enables internet access for AWS Lambda functions deployed in VPC subnets by creating NAT Gateway infrastructure, configuring public/private subnet routing, and updating security groups. Use when a VPC-attached Lambda function cannot reach the internet.

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/lambda-vpc-internet-access.md`).

It sits in Backend & APIs, covering Serverless. It works with AWS Lambda. The repository describes itself as: Official, AWS-supported MCP servers, skills, and plugins to help AI agents build on AWS. The licence is Apache-2.0.

When your agent uses it

  • A VPC-attached Lambda function cannot reach the internet
  • Tasks that involve Serverless

Example prompts

  • “Use the enabling-lambda-vpc-internet-access skill to enable internet access for AWS Lambda functions deployed in VPC subnets by creating NAT Gateway…”
  • “/enabling-lambda-vpc-internet-access”

What it can do on your machine

Read from SKILL.md and the folder at commit bd49cc8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Enabling Lambda Vpc Internet Access loads about 424 tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 193 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~424
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
