## Which one, for what

### Microsoft Dynamics 365 Sales (B)

Good for: Organisations already on Dynamics 365 or Microsoft 365 that want an agent to work inside existing security roles.

Ahead on:
- Reliability, 65 against 42
- Schema & documentation, 81 against 57
- Agent ergonomics, 86 against 44
- Security & auth, 74 against 58
- Maintenance & community, 79 against 46

Also in its favour:
- Runs on your own machine

Watch for: No public OpenAPI document. The contract is an OData CSDL $metadata document served by each environment behind sign-in

### Nutshell (D)

Good for: Small sales teams already on Nutshell who want an agent to read pipeline data over MCP or write records over REST at a low seat price.

Ahead on:
- Payments & pricing, 35 against 25

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No rate limit numbers, 429 handling or Retry-After found for the REST API

## 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.

**Nutshell.** The REST reference is served as Markdown with an OpenAPI fragment per operation, and the hosted MCP server uses OAuth with PKCE and can only read. No rate limit numbers, error format or API changelog were found in the reviewed documentation, and API keys carry no scopes.

## 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`

### Nutshell

1. 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`
2. Use IDs in the `<number>-<type>` form, such as `3-accounts`, and send updates as JSON Patch with `content-type: application/json-patch+json`
3. 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
4. Use the REST API for writes. The MCP server only reads, and OAuth tokens need the `read` scope
5. Filter webhook events yourself, because every webhook receives all events and subscriptions are created in Setup, not through the API
