## Which one, for what

### Cloudflare R2 (BB)

Good for: Files an agent stores and then serves to the public, where free egress dominates, and for operators who want short-lived, path-scoped credentials.

Ahead on:
- Reliability, 82 against 77
- Schema & documentation, 92 against 63
- Agent ergonomics, 90 against 73
- Security & auth, 83 against 77
- Maintenance & community, 87 against 37

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: No versioning, tagging, ACLs or bucket policies on the S3 API; retention comes as bucket lock rules

### DigitalOcean Spaces (B)

Good for: Teams already on DigitalOcean that want object storage with a CDN and a flat $5 entry price for up to 250 GiB, with free transfer to Droplets in the same region.

Watch for: The Spaces MCP server has ten tools for access keys and CDN endpoints. None reads, writes, lists or shares an object

## Verdicts

**Cloudflare R2.** Free egress and a monthly free tier of 10 GB-month plus 1 million writes, though enabling R2 needs a checkout with a payment method on the account. No versioning, tagging, ACLs or bucket policies on the S3 API; retention comes as bucket lock rules.

**DigitalOcean Spaces.** Per-bucket access keys with read or read-write-delete grants, an 800 operations a second limit per bucket and a 99.9 per cent SLA are all published. The MCP server manages keys and CDN endpoints only, not objects, and the S3 reference documents no error codes. A payment method is required before any bucket is created.

## Before you call either

### Cloudflare R2

1. Set region to `auto` and the endpoint to https://<account-id>.r2.cloudflarestorage.com. `us-east-1` also works, other region names fail
2. Ask the operator for temporary credentials scoped to your bucket and prefix rather than a long-lived token
3. For public reads put a custom domain or an r2.dev subdomain on the bucket; presigned URLs only sign the S3 hostname
4. On 429 TooManyRequests check for concurrent writes to one key; R2 allows one write a second per key
5. Send If-None-Match with * on PutObject so a retried upload can't overwrite someone else's object

### DigitalOcean Spaces

1. Set the endpoint to `https://<region>.digitaloceanspaces.com` and, in AWS SDKs other than Python's, set `region` to `us-east-1` when creating a bucket
2. Ask for a limited access key with a Read or Read/Write/Delete grant on one bucket. A full access key can create, configure and delete every bucket
3. Do the object work through the S3 API. The MCP server and `doctl` cannot upload, list, move or delete files
4. Retry with exponential backoff on `503 Slow Down`, and keep below 800 operations a second per bucket
5. Fetch presigned links from the origin host, not the CDN. The docs say presigned requests through the CDN are not cached and can double the bandwidth charge
6. Avoid many tiny objects. Each bills as at least 4 KiB on Standard and 128 KiB on Cold Storage, which also has a 30-day minimum
