SugarAI (SugarCRM) D

Good for Companies already running Sugar Sell, Serve or Enterprise that want an agent to read and write records under a named user's roles, and that have Sugar's approval for the integration.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

The AI Supplemental Terms forbid connecting customer-owned or third-party AI systems, agents or MCP connectors to the Services or APIs except through functionality Sugar has approved. This matters before any probe is run

Verdicts

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.

SugarAI (SugarCRM)

The REST reference covers 350 endpoint pages with filters, field selection, bulk calls and upsert by sync_key. SugarAI's AI Supplemental Terms forbid connecting a customer's or third party's AI agent or MCP connector to the APIs unless Sugar has approved it, tokens carry no scopes, and no OpenAPI file, trial or SLA was found.

Before you call either

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

SugarAI (SugarCRM)

  1. Confirm that Sugar has approved the agent integration before connecting. The AI Supplemental Terms forbid unapproved AI agents and MCP connectors on the APIs
  2. POST to /rest/v11_27/oauth2/token with grant_type password and a platform other than base, mobile or portal, or the login can end the user's own session
  3. Send the access token in the OAuth-Token header. It lasts 60 minutes by default, so store the refresh token and not the password
  4. Stay under 20 requests a second on SugarCloud and reuse one session for batches. Over-limit traffic is blocked by IP address until support lifts it
  5. Page with max_num and offset until next_offset is -1, and pass fields to keep responses small
  6. Use PATCH /integrate/:module/:sync_key_field_name/:sync_key_field_value for writes that may be retried, since it inserts or updates by sync_key
