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
