## 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 60
- Agent ergonomics, 86 against 72

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

### HubSpot API + MCP (BB)

Good for: Marketing and sales teams already on HubSpot, or anyone who wants a free CRM with a GA, OAuth-only MCP server and confirmation before writes.

Ahead on:
- Schema & documentation, 92 against 81
- Security & auth, 82 against 74
- Payments & pricing, 30 against 25
- Maintenance & community, 84 against 79
- Transparency & trust, 85 against 75

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: Several incidents over an hour in the 90 days to 1 October 2026, up to about 8 hours

## 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.

**HubSpot API + MCP.** Remote MCP server GA since 13 April 2026, OAuth 2.1 with PKCE only. Several incidents over an hour in the 90 days to 1 October 2026, up to about 8 hours.

## 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`

### HubSpot API + MCP

1. Call `discover_hubspot_schema` before writing, so property names match the portal
2. Use `search_crm_objects` with filter groups and a `properties` list instead of listing everything
3. Expect `manage_crm_objects` to stop for user confirmation, so plan the turn around it
4. Read `policyName` on a 429 to tell a 10-second burst from the daily cap
5. Ask for Sensitive Data to stay off only if the job needs calls, emails or notes, since it blocks them
