## Which one, for what

### Microsoft Dynamics 365 Sales (B)

Good for: Organisations already on Dynamics 365 or Microsoft 365 that want an agent to work inside existing security roles.

Ahead on:
- Reliability, 65 against 46
- Agent ergonomics, 86 against 80
- Security & auth, 74 against 58

Also in its favour:

### Twenty API + MCP (B)

Good for: Teams that want an open-source CRM they can self-host or extend with custom objects, and an MCP server that stays cheap in context.

Ahead on:
- Schema & documentation, 88 against 81
- Payments & pricing, 30 against 25
- Maintenance & community, 97 against 79
- Transparency & trust, 80 against 75

- Open source

Watch for: No status page found

## Verdicts

**Microsoft Dynamics 365 Sales.** Dynamics 365 Sales data sits in Dataverse, reached through the OData v4 Web API or the Dataverse MCP server with 15 tools. Service protection limits are published and 429 responses carry Retry-After. Access needs an Entra app registration and an administrator, and the public service health page showed no history to our reader.

**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

### Microsoft Dynamics 365 Sales

1. Send `OData-MaxVersion: 4.0`, `OData-Version: 4.0` and `Accept: application/json`, and name columns with `$select` on every read
2. Page with `Prefer: odata.maxpagesize` (up to 5,000) and follow `@odata.nextLink`. `$skip` is not supported
3. On 429, wait the seconds in Retry-After. The `x-ms-ratelimit-*` headers are for debugging, not pacing
4. Use PATCH on an alternate key to upsert, and add `If-Match: *` when an update must not create a record
5. For MCP, call `describe` for logical table and column names before `read_query`. Update any allow list that still names `describe_table`, `list_tables` or `fetch`

### 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
