Which one, for what

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 75
  • Agent ergonomics, 74 against 65
  • Transparency & trust, 82 against 64

Also in its favour

  • No incidents deducted, where Teable loses 3 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

Teable C

Good for Teams that want Airtable-style typed tables on PostgreSQL that they can also self-host, with an agent reading and writing records through tokens limited by scope and project, or through the vendor's CLI and skill.

Ahead on

  • Reliability, 72 against 65
  • Payments & pricing, 30 against 20

Also in its favour

  • Open source

Watch for

The OpenAPI file documents only 200 and 201 responses for nearly every operation, and the error page lists HTTP statuses without a table of error codes

Verdicts

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.

Teable

Personal access tokens and OAuth tokens carry per-action scopes, and tokens can be limited to chosen spaces and projects. The public OpenAPI file covers 841 operations. Error responses beyond 200 and 201 are missing from that file, no idempotency keys were found, and the cloud allows 10 requests a second on every plan.

Before you call either

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

Teable

  1. Send Authorization: Bearer <token> to https://app.teable.ai/api. A 403 with code restricted_resource usually means a missing scope or a project outside the token's list
  2. Page records with take of 100 at most. Personal keys created on Teable Cloud since 10 September 2026 are capped at 100 a request
  3. Ask for totals from /api/table/{tableId}/aggregation/row-count. Record lists stopped returning them by default on 2 September 2026
  4. Keep to 10 requests a second, back off on 429, and check before retrying a failed write because no idempotency key exists
  5. Pass fieldKeyType=id so renamed fields don't break writes, and leave typecast off unless values need converting
