Cloudflare R2 stores files in the cloud and serves them without fees for outgoing data. It speaks the Amazon S3 API, so existing S3 SDKs and tools can upload, list and download objects; there is also a Workers API for code that runs on Cloudflare. Access uses API tokens from a Cloudflare account. Free each month for 10 GB of storage, 1 million write and 10 million read operations; usage above that is paid. An official Cloudflare MCP server at https://mcp.cloudflare.com/mcp lets AI agents manage R2 buckets and other Cloudflare resources.
