# bun-s3-mcp
## Overview
This is an MCP service that uses Bun's [s3 bindings](https://bun.sh/docs/api/s3). The service works with Claude Desktop to save and load code snippets to S3 as markdown files.
## Features
- Use the bun runtime directly for MCP which eliminates transpilation.
- Use bun s3 bindings for fast S3 API operations.
- Shows how to configure preloading for mocking in Bun tests.
