## Which one, for what

### Capsule CRM (C)

Good for: Small teams already on Capsule who want an agent to read and write contacts, opportunities, projects and tasks over REST with a read-only scope available.

Ahead on:
- Reliability, 83 against 65
- Payments & pricing, 30 against 25

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

Watch for: No OpenAPI file, llms.txt or official SDK was found

### 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:
- Schema & documentation, 81 against 48
- Agent ergonomics, 86 against 59
- Security & auth, 74 against 46
- Maintenance & community, 79 against 38

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

## Verdicts

**Capsule CRM.** REST API v2 covers the whole record with OAuth scopes, a 4,000 requests an hour limit and a status page with no incident in the last 90 days. There is no OpenAPI file, llms.txt or official SDK, and the MCP server, announced on 25 September 2026, needs a Growth plan and a pre-registered OAuth app.

**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.

## Before you call either

### Capsule CRM

1. Send `Authorization: Bearer <token>` to `https://api.capsulecrm.com/api/v2`. Projects use the old name in paths, `/kases`
2. Follow the `Link` header for the next page. `perPage` goes up to 100 and the default is 50
3. On 429, wait until the epoch time in `X-RateLimit-Reset`. The docs suggest one second between calls
4. Ask for the `read` scope when the task only reads. A write with a read-only token answers 403 with `insufficient_scope`
5. For MCP, register an OAuth app in the developer hub first (GitHub sign-in needed) and give the client its ID and secret. Personal API tokens are refused

### 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`
