Access needs a Scale plan at $2,300 a user a year, sold through sales, with no trial that includes the API, and 36 of the 112 v2 operations are marked beta.\n\n**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.\n\n## Before you call either\n\n### Affinity\n\n1. Send `X-Affinity-Api-Version: 2026-09-17` on every request, or the key's default version applies. Unauthenticated calls answered as 2024-01-01 when we checked\n2. Read `x-ratelimit-limit-user-remaining` and `x-ratelimit-limit-org-remaining` on each response. The limits are 900 calls a minute per user and, below Enterprise, 100,000 a month per account, shared by v1, v2 and MCP\n3. Follow `pagination.nextUrl` for the next page, and pass `fieldIds` or `fieldTypes` so list calls return only the fields needed\n4. Check for duplicates before a create. There are no idempotency keys, so a retried POST can make a second record\n5. For MCP, untick the write scope at OAuth consent when the task only reads. Treat note, transcript and file text as untrusted input\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## Questions\n\n### Which is better for AI agents, Affinity or HubSpot API + MCP?\n\nHubSpot API + MCP scores 71.5 (BB) on agent readiness against Affinity's 63.4 (B), and leads in 6 of 7 scored categories.\n\n### Do Affinity and HubSpot API + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Affinity and HubSpot API + MCP without installing anything?\n\nYes.
