## Which one, for what

### Nutshell (D)

Good for: Small sales teams already on Nutshell who want an agent to read pipeline data over MCP or write records over REST at a low seat price.

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No rate limit numbers, 429 handling or Retry-After found for the REST API

### Zoho CRM (BB)

Good for: Teams already on Zoho who want an agent to read and write leads, contacts, deals and activities with narrow scopes, and small teams that want a free edition with API access.

Ahead on:
- Reliability, 72 against 42
- Schema & documentation, 81 against 57
- Agent ergonomics, 81 against 44
- Security & auth, 67 against 58
- Payments & pricing, 40 against 35
- Maintenance & community, 77 against 46

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: The documented refresh and revoke calls put the refresh token and client secret in the URL query string

## Verdicts

**Nutshell.** The REST reference is served as Markdown with an OpenAPI fragment per operation, and the hosted MCP server uses OAuth with PKCE and can only read. No rate limit numbers, error format or API changelog were found in the reviewed documentation, and API keys carry no scopes.

**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

### Nutshell

1. 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`
2. Use IDs in the `<number>-<type>` form, such as `3-accounts`, and send updates as JSON Patch with `content-type: application/json-patch+json`
3. 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
4. Use the REST API for writes. The MCP server only reads, and OAuth tokens need the `read` scope
5. Filter webhook events yourself, because every webhook receives all events and subscriptions are created in Setup, not through the API

### 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
