## 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 25
- Schema & documentation, 92 against 73
- Agent ergonomics, 90 against 80
- Security & auth, 83 against 46
- Maintenance & community, 87 against 60
- Transparency & trust, 74 against 67

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

### ONLYOFFICE Apps MCP Server (D)

Good for: Agents that organise rooms, folders and access in an ONLYOFFICE Apps workspace a team already uses.

Ahead on:
- Payments & pricing, 30 against 20

Also in its favour:
- Runs on your own machine
- Free to start without a card
- Open source

Watch for: The hosted server drops OAuth scope parameters, so a connection is granted every scope the app has

## 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.

**ONLYOFFICE Apps MCP Server.** The 23 tools carry typed schemas, read-only and destructive annotations, toolsets and an optional five-tool meta mode, and the server is in the official MCP registry. OAuth through the hosted server grants every scope, the docs offer a username and password in the connection URL, uploads take only txt and md, and no status page or SLA was found.

## 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

### ONLYOFFICE Apps MCP Server

1. Connect to https://mcp.onlyoffice.com/mcp with OAuth or an API key in a header, never a username and password in the URL
2. Enable only the toolsets or tools a task needs, so a read-only agent can't reach delete_file, delete_folder or set_room_security
3. Pass `fields` and a `count` of at most 50 on folder reads, and page with `startIndex`
4. Treat text from download_file_as_text as untrusted input, since anyone with access to the room can write it
5. Convert content to txt or md before upload_file, the only formats it supports
