Send `X-API-Version: 2025-06-09` on every REST call\n2. Set an `Idempotency-Key` on creates, and treat a 409 `IDEMPOTENCY_REQUEST_IN_PROGRESS` as wait and retry\n3. On a 429, wait until `details.retryAfter`, and remember all your keys share one 600-a-minute budget\n4. Move off the reminder endpoints to tasks before their removal on 2027-02-13\n5. Expect some interaction content to be hidden by the workspace's privacy rules\n\n### Nutshell\n\n1. Authenticate REST calls with HTTP Basic, a Nutshell user's email as username and the API key as password, against `https://app.nutshell.com/rest`\n2. Use IDs in the `\u003cnumber\u003e-\u003ctype\u003e` form, such as `3-accounts`, and send updates as JSON Patch with `content-type: application/json-patch+json`\n3. Page lists with `page[limit]` and `page[page]`, which is 0-based, and call `/accounts/list/fields` or the lead and contact equivalents for valid filter keys\n4. Use the REST API for writes. The MCP server only reads, and OAuth tokens need the `read` scope\n5. Filter webhook events yourself, because every webhook receives all events and subscriptions are created in Setup, not through the API\n\n## Questions\n\n### Which is better for AI agents, folk API + MCP or Nutshell?\n\nfolk API + MCP scores 60.8 (C) on agent readiness against Nutshell's 49.6 (D), and leads in 5 of 7 scored categories.
