## Which one, for what

### 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 48
- Security & auth, 82 against 51
- Payments & pricing, 30 against 10
- Maintenance & community, 84 against 22
- Transparency & trust, 85 against 71

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Runs on your own machine
- 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

### 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.

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`
