Verdicts

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.

Zoho CRM

A public OpenAPI 3.1 description of 644 operations and OAuth scopes down to one module and one operation suit agent use, and the Free edition includes 5,000 API credits a day. The documented token refresh puts the client secret in the URL, and no SLA, deprecation policy or dated API changelog was found.

Before you call either

HubSpot API + MCP

  1. Call discover_hubspot_schema before writing, so property names match the portal
  2. Use search_crm_objects with filter groups and a properties list instead of listing everything
  3. Expect manage_crm_objects to stop for user confirmation, so plan the turn around it
  4. Read policyName on a 429 to tell a 10-second burst from the daily cap
  5. Ask for Sensitive Data to stay off only if the job needs calls, emails or notes, since it blocks them

Zoho CRM

  1. Use the api_domain returned with the token, since each data centre has its own host (zohoapis.com, zohoapis.eu, zohoapis.in and others)
  2. Send Authorization: Zoho-oauthtoken <token> and refresh hourly. Put refresh parameters in the POST body, not the URL
  3. Pass fields on every list call. Page with page up to 2,000 records, then page_token up to 100,000
  4. Create through /{module}/upsert so a retry updates instead of duplicating
  5. Budget credits. Convert Lead costs 5, Send Mail 20, a bulk read 50, and calls through the MCP servers draw on the same allowance
