Verdicts

Capsule CRM

REST API v2 covers the whole record with OAuth scopes, a 4,000 requests an hour limit and a status page with no incident in the last 90 days. There is no OpenAPI file, llms.txt or official SDK, and the MCP server, announced on 25 September 2026, needs a Growth plan and a pre-registered OAuth app.

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

Capsule CRM

  1. Send Authorization: Bearer <token> to https://api.capsulecrm.com/api/v2. Projects use the old name in paths, /kases
  2. Follow the Link header for the next page. perPage goes up to 100 and the default is 50
  3. On 429, wait until the epoch time in X-RateLimit-Reset. The docs suggest one second between calls
  4. Ask for the read scope when the task only reads. A write with a read-only token answers 403 with insufficient_scope
  5. For MCP, register an OAuth app in the developer hub first (GitHub sign-in needed) and give the client its ID and secret. Personal API tokens are refused

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
