Verdicts

Close API + MCP

Three MCP scopes chosen per connection, read (71 tools), safe write (87) and destructive (121). 121 MCP tools, and even the read scope loads 71.

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

Close API + MCP

  1. Connect with Close-Scope: mcp.read unless the job needs writes, and mcp.write_safe if it only creates
  2. Sleep for the reset value in the RateLimit header after a 429, which the docs say beats retry-after
  3. Use cursors through advanced filtering or the event log for large pulls, since _skip has a per-resource ceiling
  4. Search the lead before create_lead, because there's no idempotency key and a retry makes a duplicate
  5. Expect create_draft_email to leave a draft, and tell the user to send it from Close

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
