## Which one, for what

### Capsule CRM (C)

Good for: Small teams already on Capsule who want an agent to read and write contacts, opportunities, projects and tasks over REST with a read-only scope available.

Ahead on:
- Reliability, 83 against 51
- Schema & documentation, 48 against 27
- Agent ergonomics, 59 against 48
- Maintenance & community, 38 against 5

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

Watch for: No OpenAPI file, llms.txt or official SDK was found

### Freshsales API (E)

Good for: Small teams already paying for Freshworks who want an agent to upsert contacts and log activities through REST.

Watch for: No MCP server for Freshsales

## Verdicts

**Capsule CRM.** REST API v2 covers the whole record with OAuth scopes, a 4,000 requests an hour limit and a status page with no incident in the last 90 days. There is no OpenAPI file, llms.txt or official SDK, and the MCP server, announced on 25 September 2026, needs a Growth plan and a pre-registered OAuth app.

**Freshsales API.** Contact upsert and bulk upsert of up to 100 records make creates safe to retry. No MCP server for Freshsales.

## Before you call either

### Capsule CRM

1. Send `Authorization: Bearer <token>` to `https://api.capsulecrm.com/api/v2`. Projects use the old name in paths, `/kases`
2. Follow the `Link` header for the next page. `perPage` goes up to 100 and the default is 50
3. On 429, wait until the epoch time in `X-RateLimit-Reset`. The docs suggest one second between calls
4. Ask for the `read` scope when the task only reads. A write with a read-only token answers 403 with `insufficient_scope`
5. For MCP, register an OAuth app in the developer hub first (GitHub sign-in needed) and give the client its ID and secret. Personal API tokens are refused

### Freshsales API

1. Build the base URL from the bundle alias shown under the API key, `https://<alias>.myfreshworks.com/crm/sales/api/`
2. Use `/api/contacts/upsert` rather than create, so a retry updates instead of duplicating
3. Budget calls, since 1,000 an hour covers the whole account and 429s carry no Retry-After
4. Add `include=owner,sales_accounts` to pull related records in one call
5. Expect to see only what the key owner's role can see
