## Which one, for what

### 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

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

### OneDrive and SharePoint files (Microsoft Graph) (B)

Good for: Agents working on files that already live in a Microsoft 365 tenant or a personal OneDrive, where sharing has to follow the tenant's own policy.

Ahead on:
- Reliability, 64 against 33
- Schema & documentation, 89 against 65
- Agent ergonomics, 84 against 73
- Maintenance & community, 75 against 70
- Transparency & trust, 75 against 61

Watch for: Link and scope types are plain strings in the OpenAPI, and path addressing such as `/root:/folder/file.txt:` is absent from it

## Verdicts

**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.

**OneDrive and SharePoint files (Microsoft Graph).** One REST surface covers personal OneDrive, work OneDrive and SharePoint libraries, with resumable uploads, sharing links that take an expiry date and per-file Selected permissions. The status page needs JavaScript, an app must be registered and consented to by a person, and the JavaScript client on npm lacks a token-leak fix merged in June 2026.

## Before you call either

### 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

### OneDrive and SharePoint files (Microsoft Graph)

1. Use PUT `/content` only up to 250 MB. Above 10 MiB Microsoft advises `createUploadSession`, with fragments in multiples of 320 KiB and under 60 MiB each
2. Send the bearer token on the `createUploadSession` POST only. The PUT calls to `uploadUrl` can return 401 if an `Authorization` header is included
3. Set `expirationDateTime` and `scope` on `createLink`. Without a scope the tenant's default link type is created, which may be wider than intended
4. Follow the 302 from GET `/content` straight away. Pre-authenticated download URLs can expire within minutes and need no `Authorization` header
5. Wait for `Retry-After` on 429 and 503. Throttled requests still count against the limits, and continued overuse can get the app blocked
