aws-lambda-microvms
Build, run, debug, and operate applications on AWS Lambda MicroVMs — Firecracker-isolated, snapshot-resumable serverless compute environments that run inside a container with up to 8-hour lifetimes. Triggers on: Lambda MicroVMs, Firecracker isolation, snapshot-resumable compute, suspend/resume, sandboxed or untrusted code execution, AI/agent code-execution sandboxes, interactive code playgrounds and notebooks (Jupyter, REPLs), reinforcement-learning environments, multi-tenant CI executors and build runners, sessionful game or simulation servers, isolated security scanners, long-lived sessions, or port-listening servers (gRPC, WebSocket, custom TCP). For standard event-driven Lambda functions, use the aws-lambda skill instead.
Install
With your agent
Install OMGSkills skill "awslabs/agent-plugins:plugins/aws-serverless/skills/aws-lambda-microvms" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/awslabs/agent-plugins /tmp/agent-plugins && ln -s /tmp/agent-plugins/plugins/aws-serverless/skills/aws-lambda-microvms ~/.claude/skills/aws-lambda-microvmsFrom README
AWS Lambda MicroVMs The AWS MCP server is recommended for sandboxed execution and audit logging. AWS Lambda MicroVMs are serverless compute environments that combine Firecracker VM isolation with container-like efficiency. Each MicroVM: Runs your application as a container inside a Firecracker microVM — you can reproduce the environment locally. Runs Amazon Linux 2023 as the base OS inside the MicroVM. Boots from a memory + disk snapshot captured at image build time, so application init is skipped on run. Has a dedicated, TLS-terminated HTTPS endpoint reachable with an auth token. Can be suspended and resumed with state preserved; lives up to 8 hours. Two-resource model: MicrovmImage — a versioned artifact built from {S3 zip with Dockerfile} + baseImageArn. Each version has per-architecture/chipset Builds. Microvm — a running instance created (RunMicrovm) from an image version. Two roles: buildRoleArn — used during image build (S3 read, CloudWatch logs, optional ECR).
