## Which one, for what

### 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.

Ahead on:
- Reliability, 77 against 33
- Transparency & trust, 74 against 61

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

### Fastio (C)

Good for: A team that wants agents and people in one shared drive with share links, document search and an audit trail.

Ahead on:
- Payments & pricing, 30 against 20
- Maintenance & community, 70 against 37

Also in its favour:
- Runs on your own machine

Watch for: No free tier. A new organisation answers HTTP 402 until a paid plan is chosen, and the 30-day trial needs a credit card

## Verdicts

**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.

**Fastio.** OAuth with PKCE, scoped API keys with read, write and admin modes, and separate read and write MCP tools limit what an agent can touch. There is no free tier, the 30-day trial needs a card, and no status page, SLA, OpenAPI file or public changelog was found.

## Before you call either

### 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

### Fastio

1. Connect to `https://mcp.fast.io/mcp/tools` for named tools or `https://mcp.fast.io/mcp/code` for the 8-tool code mode. The URL fixes the tool set for the session
2. Call `action="describe"` on a tool before first use. Parameters live there, not in the tool list
3. To update a file, upload again with the same parent folder and filename. Deleting first loses the version history
4. On 429 wait until `x-ve-limit-expires` or the `Retry-After` value. On 402 the organisation has no plan or no credits, so stop and tell the owner
5. Ask the owner for a key scoped to one workspace with `r` or `rw`. A key made without scopes carries `user:*:rw` across the account
