Install via the recommended one-line script, Go install, binary download, or Docker. Set the required environment variable S3_BUCKET (optionally S3_REGION, S3_ENDPOINT, etc.) and create a .vscode/mcp.json file to register the server in VS Code. After installation, open VS Code and use GitHub Copilot Chat with commands like @s3YamlDocs list all YAML files to interact with your S3-hosted specifications.
