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
- Create a personal access token with only the scopes needed and add each base to it. A token with no base added sees nothing
- Stay under 5 requests a second per base. After a 429, wait 30 seconds before the next call
- Send writes in batches of 10 records, and use
performUpsertwithfieldsToMergeOnso a repeated call updates instead of duplicating - Use table and field IDs, not names, and set
returnFieldsByFieldIdso a rename doesn't break the call - POST to
/listRecordswhen afilterByFormulawould push the URL past 16,000 characters
Smartsheet API + MCP
- Send writes to one sheet one at a time. Parallel updates with the same token return error 4004
- Batch row changes, up to 500 rows a call, and add
allowPartialSuccess=trueto get per-row failures instead of a failed batch - 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
- Through MCP, call
get_columnsbefore filtering or writing. Column names are case-sensitive and guesses fail validation - Use the regional host that matches the account (api.smartsheet.com, .eu or .au). Tokens don't work across regions
