## Which one, for what

### Copper API (D)

Good for: Teams already on Copper and Google Workspace who want an agent to read and update deals and contacts through REST.

Ahead on:
- Reliability, 79 against 61
- Payments & pricing, 30 against 10

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

Watch for: No official MCP server, OpenAPI spec or llms.txt

### 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:
- Agent ergonomics, 69 against 40
- Security & auth, 51 against 27

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

**Copper API.** Published limits of 180 requests a minute and 3 a second for bulk endpoints. No official MCP server, OpenAPI spec or llms.txt.

**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

### Copper API

1. Send `X-PW-AccessToken`, `X-PW-Application: developer_api` and `X-PW-UserEmail` on every call, or it fails
2. Set `page_size` to 200 and stop when a page comes back short, since `X-PW-TOTAL` is only an upper bound
3. Back off on 429 on your own clock, since no Retry-After is documented
4. Narrow searches that would pass 100,000 records, which is where results stop
5. Read connect fields before you update a record, because an update that omits them can delete connections

### 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`
