## Which one, for what

### Grist (D)

Good for: Teams that want a relational spreadsheet with Python formulas and per-document OAuth grants for an agent, or that need to self-host.

Ahead on:
- Payments & pricing, 30 against 20

Also in its favour:
- Open source

Watch for: No status page was found. status.getgrist.com redirects to a signup form, and the site footer and help centre link to none

### Smartsheet API + MCP (B)

Good for: An agent working inside a company that already runs projects in Smartsheet on a Business plan or above, especially row-level reads and batched writes, workflows and dashboards.

Ahead on:
- Reliability, 65 against 39
- Schema & documentation, 88 against 63
- Agent ergonomics, 74 against 57
- Transparency & trust, 82 against 61

Also in its favour:
- No incidents deducted, where Grist loses 4 points for them

Watch for: API and MCP access need a Business plan or higher, from $19 a member a month billed yearly with a three-member minimum

## Verdicts

**Grist.** OAuth tokens carry seven scopes, can be limited to chosen documents and expire after an hour, and the REST API has a public OpenAPI file with an add-or-update call. No status page, SLA terms, DPA or security.txt was found, and the docs say the hosted service has no SOC 2 or ISO 27001 audit.

**Smartsheet API + MCP.** The REST API has a public OpenAPI 3.0.3 spec with 187 operations, Markdown docs and llms.txt, and the hosted MCP server loads its 83 documented tools by toolset. API access needs a Business plan or higher, and the status page lists eight incidents marked major or critical between 15 July and 21 September 2026.

## Before you call either

### Grist

1. Connect through OAuth, not an API key. Ask for `doc:read` alone for reading, and have the user pick Selected resources on the consent screen
2. Keep `doc.schema:write` off unless needed. The docs say formula editing lets its holder read any data in the document whatever the access rules
3. Send requests for one document one at a time. The eleventh concurrent request gets 429, and no Retry-After header is documented
4. Use `PUT /api/docs/{docId}/tables/{tableId}/records` with `require` to add or update by key, so a retried write doesn't create a duplicate row
5. Use the `/records` endpoints, not the deprecated `/data` ones, and split large writes to stay under the 1 MB body limit

### Smartsheet API + MCP

1. Send writes to one sheet one at a time. Parallel updates with the same token return error 4004
2. Batch row changes, up to 500 rows a call, and add `allowPartialSuccess=true` to get per-row failures instead of a failed batch
3. On error 4003 (HTTP 429) wait at least 60 seconds before retrying. The limit is 300 requests a minute per token, 30 for attachments and cell history
4. Through MCP, call `get_columns` before filtering or writing. Column names are case-sensitive and guesses fail validation
5. Use the regional host that matches the account (api.smartsheet.com, .eu or .au). Tokens don't work across regions
