## 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:
- Schema & documentation, 81 against 35

- Security & auth, 74 against 52
- Payments & pricing, 25 against 20
- Maintenance & community, 79 against 60
- Transparency & trust, 75 against 65

Good for: Small teams that run deals out of Gmail and want an agent to update pipelines and add tasks without seeing email bodies.

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: MCP tool list and count not published

## Verdicts

## 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`

### Streak API + MCP

1. Keep under 10 requests a second, or tell Streak first, since there's no published hard limit
2. Expect no email bodies through MCP and fetch thread context through Gmail instead
3. Send the API key as the Basic auth username with an empty password
4. Check the plan before relying on webhooks, which start at Pro+
5. Handle a 410 as an API version that's no longer supported
