No rate limit numbers, error format or API changelog were found in the reviewed documentation, and API keys carry no scopes.\n\n## Before you call either\n\n### HubSpot API + MCP\n\n1. Call `discover_hubspot_schema` before writing, so property names match the portal\n2. Use `search_crm_objects` with filter groups and a `properties` list instead of listing everything\n3. Expect `manage_crm_objects` to stop for user confirmation, so plan the turn around it\n4. Read `policyName` on a 429 to tell a 10-second burst from the daily cap\n5. Ask for Sensitive Data to stay off only if the job needs calls, emails or notes, since it blocks them\n\n### Nutshell\n\n1. 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`\n2. Use IDs in the `\u003cnumber\u003e-\u003ctype\u003e` form, such as `3-accounts`, and send updates as JSON Patch with `content-type: application/json-patch+json`\n3. 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\n4. Use the REST API for writes. The MCP server only reads, and OAuth tokens need the `read` scope\n5. Filter webhook events yourself, because every webhook receives all events and subscriptions are created in Setup, not through the API\n\n## Questions\n\n### Which is better for AI agents, HubSpot API + MCP or Nutshell?\n\nHubSpot API + MCP scores 71.5 (BB) on agent readiness against Nutshell's 49.6 (D), and leads in 6 of 7 scored categories.
