## 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.

**Twenty API + MCP.** Six MCP meta-tools by default with schemas loaded on demand, and `?mode=direct` for clients that load lazily. No status page found.

## 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

### Twenty API + MCP

1. Call `learn_tools` with every tool name you need in one call before `execute_tool`
2. Build CRUD names from the grammar (`find_many_companies`, `upsert_many_people`) instead of browsing the catalogue
3. Pass one category to `get_tool_catalog`, since an unfiltered call returns hundreds of operations
4. Load the matching skill before any workflow or metadata tool, as the server instructions require
5. Batch up to 60 records a call to stay inside 100 requests a minute
