## Which one, for what

### Nutshell (D)

Good for: Small sales teams already on Nutshell who want an agent to read pipeline data over MCP or write records over REST at a low seat price.

Ahead on:
- Schema & documentation, 57 against 48
- Security & auth, 58 against 51
- Payments & pricing, 35 against 10
- Maintenance & community, 46 against 22

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No rate limit numbers, 429 handling or Retry-After found for the REST API

### 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.

Ahead on:
- Reliability, 61 against 42
- Agent ergonomics, 69 against 44

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

**Nutshell.** The REST reference is served as Markdown with an OpenAPI fragment per operation, and the hosted MCP server uses OAuth with PKCE and can only read. No rate limit numbers, error format or API changelog were found in the reviewed documentation, and API keys carry no scopes.

**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

### Nutshell

1. Authenticate REST calls with HTTP Basic, a Nutshell user's email as username and the API key as password, against `https://app.nutshell.com/rest`
2. Use IDs in the `<number>-<type>` form, such as `3-accounts`, and send updates as JSON Patch with `content-type: application/json-patch+json`
3. Page lists with `page[limit]` and `page[page]`, which is 0-based, and call `/accounts/list/fields` or the lead and contact equivalents for valid filter keys
4. Use the REST API for writes. The MCP server only reads, and OAuth tokens need the `read` scope
5. Filter webhook events yourself, because every webhook receives all events and subscriptions are created in Setup, not through the API

### 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`
