## Verdicts

**Microsoft Dynamics 365 Sales.** Dynamics 365 Sales data sits in Dataverse, reached through the OData v4 Web API or the Dataverse MCP server with 15 tools. Service protection limits are published and 429 responses carry Retry-After. Access needs an Entra app registration and an administrator, and the public service health page showed no history to our reader.

**folk API + MCP.** Dated API versions, a year's support and 6 months' deprecation notice with `Deprecation` and `Sunset` headers. MCP server in open beta since 1 July 2026.

## Before you call either

### Microsoft Dynamics 365 Sales

1. Send `OData-MaxVersion: 4.0`, `OData-Version: 4.0` and `Accept: application/json`, and name columns with `$select` on every read
2. Page with `Prefer: odata.maxpagesize` (up to 5,000) and follow `@odata.nextLink`. `$skip` is not supported
3. On 429, wait the seconds in Retry-After. The `x-ms-ratelimit-*` headers are for debugging, not pacing
4. Use PATCH on an alternate key to upsert, and add `If-Match: *` when an update must not create a record
5. For MCP, call `describe` for logical table and column names before `read_query`. Update any allow list that still names `describe_table`, `list_tables` or `fetch`

### folk API + MCP

1. Send `X-API-Version: 2025-06-09` on every REST call
2. Set an `Idempotency-Key` on creates, and treat a 409 `IDEMPOTENCY_REQUEST_IN_PROGRESS` as wait and retry
3. On a 429, wait until `details.retryAfter`, and remember all your keys share one 600-a-minute budget
4. Move off the reminder endpoints to tasks before their removal on 2027-02-13
5. Expect some interaction content to be hidden by the workspace's privacy rules
