## Which one, for what

### Breakcold (C)

Good for: Small sales teams who run outreach on email and social channels and want an agent to keep records, tasks and replies in order.

Ahead on:
- Schema & documentation, 90 against 81

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Microsoft Dynamics 365 Sales loses 6 points for them

Watch for: No status page or SLA was found; status.breakcold.com did not answer

### 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 45
- Agent ergonomics, 86 against 67
- Security & auth, 74 against 60
- Payments & pricing, 25 against 15
- Maintenance & community, 79 against 60
- Transparency & trust, 76 against 67

Also in its favour:
- Runs on your own machine

Watch for: No public OpenAPI document. The contract is an OData CSDL $metadata document served by each environment behind sign-in


## Why the edge

### Reliability: Microsoft Dynamics 365 Sales +20

- Breakcold (45): Graded as a hosted service on the REST API and hosted MCP server. No status page is linked from the site or docs, and status.breakcold.com failed the TLS handshake (0). With no readable history the incident line scores 5. Rate limits published per organisation (600 a minute), workspace (300), identity or key (180) and route (120), for REST and MCP (15). 429 carries Retry-After and `retryAfterMs`, the docs give backoff guidance, and creates take an Idempotency-Key so retries return the original result (15). No SLA found in the services agreement summary, the pricing page or the docs (0). Neither surface is marked beta (10). 0 + 5 + 15 + 15 + 0 + 10 = 45.
- Microsoft Dynamics 365 Sales (65): Graded on the Dataverse Web API, with the Dataverse MCP server noted. Service health for a tenant is in the Power Platform and Microsoft 365 admin centres, behind an admin sign-in. The unauthenticated page at status.cloud.microsoft exists, and Microsoft's docs describe it as the place for updates when the admin portals are unavailable. It rendered no components for our reader on 8 October, and on 1 November its robots.txt answered an empty 401, so the host is treated as blocked and wasn't read (10 of 20, a departure from the full 20 because the page with history needs a login). No readable incident history. The Azure status history, which the Azure listings are read from, names no Dynamics 365, Dataverse or Power Platform incident in the 90 days to 1 November and doesn't cover these services (5). Service protection limits are published per user and web server at 6,000 requests and 20 minutes of execution time per five-minute window, and 52 concurrent requests, plus 40,000 requests per licensed user per 24 hours (15). 429 responses carry Retry-After with retry guidance, and upsert on alternate keys with If-Match gives safe retries for writes (15). The SLA for Microsoft Online Services dated 1 October 2026 pays a 25 per cent credit below 99.9 per cent uptime for Sales Enterprise and Professional, per the 8 October check (10). Web API v9.2 and the MCP endpoint /api/mcp are generally available (10).

### Agent ergonomics: Microsoft Dynamics 365 Sales +19

- Breakcold (67): 72 MCP tools (5), with `tools_search` and `capabilities_list` to find tools by capability or granted scope, and scopes that limit which tools apply (8 back). Cursor pagination, record search and a `fields` selection on record lists since 3 November (18 of 20). Errors carry a code, message, `requestId` and `retryAfterMs`, and the 4 November changelog removed stack frames from messages (17 of 20). Idempotency keys on creates, and compose and send tools return a non-sending draft by default; MCP annotations are not published (14 of 20). No official SDK; setup is one URL with OAuth (5 of 15). 13 + 18 + 17 + 14 + 5 = 67.
- Microsoft Dynamics 365 Sales (86): `$select`, `$top` and `Prefer: odata.maxpagesize` size responses. The MCP server has 15 tools, some of them for schema changes and files (22 of 25). `$filter`, `@odata.nextLink` paging with pages up to 5,000 rows, and no `$skip` (20). Errors are JSON with a code and message, a documented status code table and optional annotations with a help link (17 of 20). PATCH on an alternate key upserts, `If-Match` and `If-None-Match` limit it to update or create, and ETags give optimistic concurrency. The MCP delete tools are described as running only after explicit user approval. We did not read the live tool list, so readOnlyHint and destructiveHint are unconfirmed (15 of 20). Official SDKs for .NET (Microsoft.PowerPlatform.Dataverse.Client 1.2.27) and Python (PowerPlatform-Dataverse-Client 1.1.0). The docs say Microsoft ships no other language libraries for the Web API (12 of 15).

### Maintenance & community: Microsoft Dynamics 365 Sales +19

- Breakcold (60): API changelog entry on 6 November 2026 (30). More than 60 dated entries since 8 August 2026 (20). Closed service with a public API changelog, an RSS feed, a help centre and support by email; no public issue tracker (10 of 15). The CRM MCP server is not in the official MCP registry (the registry's io.github.breakcold/inboxmcp is a separate product at inbox-mcp.com), and no official SDK exists (0). No package to check (0). 30 + 20 + 10 + 0 + 0 = 60.
- Microsoft Dynamics 365 Sales (79): Dataverse service update 9.2.26103 went to early release on 23 October 2026, with production rollout from 30 October (30). Service updates are weekly, with 9.2.26081 to 9.2.26103 listed from August to October 2026, each with release notes, and Python SDK 1.0.1 (8 September) and 1.1.0 (7 October) and .NET SDK 1.2.27 (4 September) in the window (20). Public release notes and community forums. We did not check how issues on the SDK repositories are answered (10 of 15). Current official SDKs for .NET and Python and the npm MCP proxy @microsoft/dataverse, whose 1.0.81 of 26 September 2026 rests on the 8 October check. The official MCP registry lists only third-party Dataverse and Dynamics servers, per the 8 October check (13 of 15). The Python SDK is marked Production/Stable for Python 3.10 and later and has a python-package workflow, but its runs weren't readable because github.com refused us (6 of 10).

### Security & auth: Microsoft Dynamics 365 Sales +14

- Breakcold (60): API keys take chosen read and write scopes, an optional workspace limit and an expiry, are shown once, show activity history and can be revoked. MCP also accepts OAuth with PKCE through WorkOS AuthKit. Tokens travel in headers (30). Read-only keys are possible and message sends stay drafts until `sendMode` is set after the user confirms (17 of 20). The inbox returns email, LinkedIn, WhatsApp and Telegram text from outside parties, and no prompt-injection guidance was found (0). API key activity history is visible to the user; no organisation audit log was found (7 of 15). A vulnerability disclosure policy (3 September 2026) with reports to support@breakcold.com, no bounty, no security.txt (404) and no SOC 2 or ISO 27001 found (6 of 20). 30 + 17 + 0 + 7 + 6 = 60.
- Microsoft Dynamics 365 Sales (74): OAuth 2.0 through Microsoft Entra ID is the only route, with delegated sign-in or an application user holding a client secret or certificate. The OAuth scopes are coarse (`user_impersonation`, `.default`, `mcp.tools`) and the limits come from Dataverse security roles (26 of 30). Security roles set privileges per table and the MCP server follows them and row-level security. Each MCP client app must be allowed per environment by an administrator, and only Copilot Studio is on by default. The delete tools are described as needing explicit user approval, but Microsoft's sample agent instructions on the configuration page tell the agent not to ask before deleting (17 of 20). Lead, contact and email text written by outsiders reaches the model, and the MCP pages we read give no injection guidance (3 of 15). Dataverse auditing logs record changes and user access, readable through the Web API, once an administrator turns it on. It does not cover retrieve operations (13 of 15). SOC 2 Type 2 lists Dynamics 365, per the 8 October check, and security.txt points to MSRC and the bounty policy, but the file's Expires date of 23 September 2026 had still passed on 1 November. MSRC publishes CVEs for service-side flaws in Dynamics 365 and Dataverse. Three Critical ones in the last 12 months name Dynamics 365 (online) or Dataverse and are counted under negative events, and a fourth names only Dynamics 365 without the app (15 of 20).

### Payments & pricing: Microsoft Dynamics 365 Sales +10

- Breakcold (15): No x402, MPP or L402 (0). Plan prices are public, and each call's cost in usage tokens is published, but the money value of a token is not (10). The 14-day trial needs a card (0). auth.md documents an agent identity endpoint that takes an identity assertion or an anonymous request followed by a claim by a person, which we read and did not call; access still needs a paid or card-backed trial account (5 of 20). 0 + 10 + 0 + 5 = 15.
- Microsoft Dynamics 365 Sales (25): No x402, MPP or L402 (0). Seat prices are public at $65, $105 and $150 a user a month, paid yearly. MCP calls from agents built outside Copilot Studio are billed in Copilot Credits at published credit counts, and we did not read a dollar price per credit (10). The Dynamics 365 trial page states 30 days free and the Power Apps Developer Plan is a free Dataverse environment with Web API access. Neither page says whether a card is needed (15 of 20). A person registers an app in Entra ID and an administrator creates the application user or allows the MCP client (0).

### Schema & documentation: Breakcold +9

- Breakcold (90): OpenAPI 3.1 contract at docs.breakcold.com/api/openapi.json with 70 operations, each with a description (25). llms.txt and a Markdown copy of each page, plus auth.md and an MCP server card (10). Tool descriptions say how to use them, such as `records_create` asking for every required field and a stable idempotency key and the send tools saying to send only after the user confirms (17 of 20). 84 enums and 488 required lists, with typed attribute pages for each field type (13 of 15). Every operation documents 400 to 429 responses and the error body is shown, but the spec carries only two examples (10 of 15). /api/v1, and an API changelog with dated entries and migration steps (15). 25 + 10 + 17 + 13 + 10 + 15 = 90.
- Microsoft Dynamics 365 Sales (81): Each environment serves an OData v4 service document and a CSDL $metadata document at /api/data/v9.2/$metadata, and Learn publishes a table reference. No public OpenAPI document was found (18 of 25). learn.microsoft.com/llms.txt returns 404, but Learn returns Markdown for requests with `Accept: text/markdown`, which is how we read every page (10). The docs state purpose and limits, such as no `$skip` and a 5,000-row page ceiling. The published MCP tool descriptions are one line each (15 of 20). Entity types are typed in CSDL, but queries are OData strings and the MCP `read_query` tool takes a SQL SELECT string (12 of 15). Request and response examples on each page, a status code table with named errors, and a JSON error format with optional detail annotations (13 of 15). The version is in the URL (v9.2), with weekly Dataverse service update release notes. The MCP tool changes are noted without a date (13 of 15).

## Verdicts

**Breakcold.** Breakcold's API and hosted MCP server are built for agents, with an OpenAPI contract, scoped and expiring keys, published rate limits, idempotency keys and message sends that stay drafts until confirmed. No status page, SLA or security certification was found, and the only trial needs a card on a plan from $99 a month.

**Microsoft Dynamics 365 Sales.** Dynamics 365 Sales data sits in Dataverse, reached via 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, no public incident history was readable, and Microsoft disclosed three Critical service-side flaws in Dataverse and Dynamics in 2026.

## Before you call either

### Breakcold

1. Call `capabilities_list` or `tools_search` first to see which tools the granted scopes allow
2. Send an Idempotency-Key on REST creates and a stable idempotency key on `records_create`, so retries return the original result
3. Leave `sendMode` unset on compose and send tools until the user has confirmed the message
4. Pass `fields` on record lists to cut the response to the fields you need
5. On 429 wait for Retry-After or `retryAfterMs`; over MCP the error code is -32029

### 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`
