What it does
Sitetositevpn is an agent skill from aws/agent-toolkit-for-aws, published by the product's own GitHub organization. Configures AWS Site-to-Site VPN: creating an IPsec VPN connection between an on-premises network and a VPC, choosing the target gateway (virtual private gateway, transit gateway, or AWS Cloud WAN), choosing static or dynamic (BGP) routing, sizing tunnel bandwidth (Standard 1.25 Gbps or Large 5 Gbps), connecting many sites through a VPN Concentrator, applying the customer gateway device configuration, making a connection highly available, and monitoring tunnels with CloudWatch. Applicable when the user wants to…
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/applying-the-customer-gateway-device-configuration.md`, `references/choosing-static-or-dynamic-routing.md` and `references/choosing-tunnel-bandwidth-standard-or-large.md`).
It sits in DevOps & Cloud. It works with Amazon Web Services. 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
- Wants to connect a data center
- Branch office to AWS over an encrypted tunnel
- Choose how routes are exchanged
- Scale throughput

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

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

Network
Links to these hosts (documentation or services it may open):

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
Sitetositevpn loads about 1.4k tokens when it runs, and up to ~25k if it reads all its reference files. Until then it costs about 232 tokens; SKILL.md has 528 words of instructions outside code blocks.
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.

AWS Site-to-Site VPN
Overview
Domain expertise for configuring AWS Site-to-Site VPN, the managed service that builds an encrypted IP Security (IPsec) connection between an on-premises network and AWS. Covers the routing decision (static versus dynamic (BGP) routing), creating the connection and its dependent resources in the right order, sizing tunnel bandwidth, consolidating many sites through a VPN Concentrator, applying the customer gateway device configuration, building for high availability, and monitoring and troubleshooting tunnels.
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. Site-to-Site VPN is a regional service: pass
--region {region} matching the VPC or transit gateway the connection terminates on.
Which Site-to-Site VPN task do you need?
| Goal | Reference |
|---|---|
| Decide between static and dynamic (BGP) routing before creating a connection | choosing static or dynamic routing |
| Create an encrypted VPN connection from on-premises to a VPC | creating a site-to-site vpn connection |
| Size tunnel bandwidth at Standard (1.25 Gbps) or Large (5 Gbps) | choosing tunnel bandwidth |
| Connect 25 or more low-bandwidth sites through one shared attachment | connecting many sites with a vpn concentrator |
| Configure the on-premises customer gateway device | applying the customer gateway device configuration |
| Make the connection survive tunnel maintenance and device failure | making a connection highly available |
| Detect a down tunnel and find out why | monitoring and troubleshooting tunnels |

Routing notes
- Decide routing before you build. The static-versus-dynamic decision shapes the customer gateway, the failover behavior, and whether the customer can control which routes enter their network. Run the choosing-static-or-dynamic-routing reference before creating the connection so the customer does not have to recreate it to change routing type.
- The target gateway gates almost everything. A virtual private gateway terminates the VPN at one VPC. A transit gateway fronts many VPCs and is the only target that supports Large (5 Gbps) tunnels, equal-cost multi-path (ECMP) bandwidth aggregation, IPv6 customer gateways, and the VPN Concentrator. The gateway choice lives in the creating reference and is referenced again by the bandwidth and concentrator references, because picking a virtual private gateway closes those doors.
- Bandwidth sizing vs the Concentrator. Both scale capacity, in opposite directions. Large tunnels give one connection more throughput (up to 5 Gbps per tunnel); the Concentrator gives many low-bandwidth sites a shared 5 Gbps attachment so each site does not need its own full-bandwidth connection. Match the reference to whether the customer has one high-throughput site or many small ones.
- AWS side vs device side. Creating the connection and downloading the configuration happen on the AWS side; applying that configuration happens on the customer's on-premises device, which AWS never touches. The applying-the-customer-gateway-device-configuration reference is device-side education, not an AWS-side step.
- Monitoring is its own task. Detecting and diagnosing a down tunnel (CloudWatch metrics, alarms, and VPN logs) is the monitoring reference, separate from building the connection.
