## Which one, for what

### Airtable (BB)

Good for: Teams that already keep operational data in Airtable and want an agent to read, filter and update typed records or build bases through MCP.

Ahead on:
- Reliability, 94 against 65
- Security & auth, 78 against 66
- Payments & pricing, 30 against 20

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

Watch for: 5 requests a second per base, and a 429 blocks further requests for 30 seconds

### 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:
- Schema & documentation, 88 against 73
- Agent ergonomics, 74 against 68
- Maintenance & community, 80 against 49

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

**Airtable.** Tokens are limited by scope and by base, and the official MCP server at mcp.airtable.com covers records, schema, interfaces and automations in 40 tools. The REST API allows 5 requests a second per base with a 30-second lockout after a 429, writes take 10 records a call, and the Free plan stops at 1,000 calls a month.

**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

### Airtable

1. Create a personal access token with only the scopes needed and add each base to it. A token with no base added sees nothing
2. Stay under 5 requests a second per base. After a 429, wait 30 seconds before the next call
3. Send writes in batches of 10 records, and use `performUpsert` with `fieldsToMergeOn` so a repeated call updates instead of duplicating
4. Use table and field IDs, not names, and set `returnFieldsByFieldId` so a rename doesn't break the call
5. POST to `/listRecords` when a `filterByFormula` would push the URL past 16,000 characters

### 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
