Verdicts
Coda (Superhuman Docs)
API tokens can be limited to one doc or one table and to read or write, and the OpenAPI description covers 125 operations with 429 on almost all. Writes are queued and answered with 202, so each needs a status check. The REST API has no idempotency keys or official client libraries, and the MCP server is in beta.
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
Coda (Superhuman Docs)
- Poll
/mutationStatus/{requestId}after every row write. A 202 means queued, and the edit can still fail - Send
X-Coda-Doc-Version: latestwhen a read must reflect recent edits, and handle the 400 it returns when the snapshot is behind - Use
keyColumnsonPOST .../rowsso a retried insert updates the same row instead of adding a duplicate - Ask for a token restricted to the one doc or table and to read access where the task allows. An unrestricted token can do anything its owner can
- Read MCP tool names from the tool list at run time. The vendor says names and parameters can change during the beta
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
