## 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.

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

### HubSpot API + MCP (BB)

Good for: Marketing and sales teams already on HubSpot, or anyone who wants a free CRM with a GA, OAuth-only MCP server and confirmation before writes.

Ahead on:
- Reliability, 60 against 45
- Agent ergonomics, 72 against 67
- Security & auth, 82 against 60
- Payments & pricing, 30 against 15
- Maintenance & community, 84 against 60
- Transparency & trust, 85 against 67

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine
- Free to start without a card

Watch for: Several incidents over an hour in the 90 days to 1 October 2026, up to about 8 hours


## Why the edge

### Maintenance & community: HubSpot API + MCP +24

- 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.
- HubSpot API + MCP (84): Developer Platform 2026.09 and a changelog post on 15 September 2026 (30). Changelog posts on 11 August, 14 August, 27 August, 8 September and 15 September 2026 (20). Public changelog and developer community. We didn't check forum response times (12 of 15). Not in the official MCP registry under a HubSpot namespace, only third-party servers, but official SDKs are current (15). The Node SDK has test and lint CI and moved to Node 22 in 14.0.0, but still wraps the v3 APIs that lose support in September 2027 (7 of 10).

### Security & auth: HubSpot API + MCP +22

- 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.
- HubSpot API + MCP (82): The remote MCP server takes only OAuth 2.1 with PKCE, with scopes set by the tools and the user's grant. REST uses OAuth apps or Service Keys, which are scoped and rotate with a 7-day grace period (30). Writes need explicit user confirmation after a proposed-changes summary, MCP has no delete tools, and turning on Sensitive Data blocks calls, emails, meetings, notes and tasks from the MCP server. No documented read-only mode (17 of 20). The server reads emails, conversations and notes written by outsiders, and we found no injection guidance beyond the Sensitive Data switch (5 of 15). Account activity history can be viewed and exported per the trust centre. Nothing MCP-specific is documented (10 of 15). PGP-signed security.txt valid until 2034, a HackerOne bug bounty, SOC 1 Type II, SOC 2 Type II and SOC 3 (20).

### Transparency & trust: HubSpot API + MCP +18

- Breakcold (67): Closed service with a legal centre whose terms name Logike SAS, its registration and French law (15 of 30). The privacy policy of 27 October 2026 and the DPA agree, give retention periods for specific copies (deleted record snapshots 30 days, exports 7 days, import rows 90 days, call recordings 30 to 365 days) and promise breach notice without undue delay (27 of 30). The developer terms tie notice of material breaking changes to the services agreement, and the changelog gives migration steps, with no fixed notice period found (12 of 20). DPA Annex C lists providers and their functions with 30 days' notice of changes; locations are said to depend on configuration, with US and EU app regions (15 of 20). 15 + 27 + 12 + 15 = 69.
- HubSpot API + MCP (85): Closed service with terms naming HubSpot, Inc. (15). Privacy policy updated 16 September 2026 with a DPA whose Annex 3 lists subprocessors. Retention reads 'a reasonable period', and the policy says HubSpot may process personal data to train its AI models (18 of 30). Dated sunsets, Pipelines v1 on 4 December 2026 (announced 14 August) and v1 to v3 APIs and legacy apps in September 2027 (announced 15 September 2026), plus date-based API versions (20). Subprocessor page and regional data centres disclosed (18 of 20).

### Reliability: HubSpot API + MCP +15

- 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.
- HubSpot API + MCP (60): Status page at status.hubspot.com with component history (20). Twelve entries since 3 July 2026, several over an hour on core platform services, among them EU customer platform tools impaired for 3 h 9 min on 22 July, event ingestion delayed 5 hours on 28 July, workflow actions delayed 5 h 45 min on 21 August and the Salesforce integration down about 8 hours on 24 September. None names the public API or the MCP server, which is why this isn't 0 (5). Limits published per app type and tier, 100 to 190 requests per 10 seconds and 250,000 to 1,000,000 a day for private apps, 110 per 10 seconds for public apps (15). 429s carry `errorType` RATE_LIMIT and `policyName`, and responses carry `X-HubSpot-RateLimit-*` headers, but the usage page gives no Retry-After or backoff guidance and we found no idempotency keys for CRM writes (10 of 15). No SLA found in what we read (0). Remote MCP server GA since 13 April 2026, though about ten tools for revenue objects and quotes are beta (10).

### Payments & pricing: HubSpot API + MCP +15

- 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.
- HubSpot API + MCP (30): No x402, MPP or L402 (0). Plan prices public, Starter $7 a seat a month yearly or $20 monthly, Professional $90 or $100 plus $1,500 onboarding, Enterprise $150 plus $3,500, with extra HubSpot Credits at $0.010 each. API calls themselves aren't priced (10). Free CRM for up to 2 users with no card, and the API and remote MCP work on it (20). A person signs up in a browser and creates the MCP connector or app (0).

### Agent ergonomics: HubSpot API + MCP +5

- 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.
- HubSpot API + MCP (72): 32 MCP tools (5), with scopes trimmed to the tools and permissions the user grants at install, and `discover_hubspot_schema` and `tool_guidance` to fetch context on demand (3 more, 8 of 25). Search takes filter groups, sorts, a 200-record page and a `properties` list, and REST reads select properties (20). Errors carry a category and a correlation ID (16 of 20). `manage_crm_objects` shows a proposed-changes summary and needs the user's confirmation before any create or update, and there's no delete tool. We found no `readOnlyHint` or `destructiveHint` documented and no idempotency keys (13 of 20). Official SDKs for Node (14.0.1, 1 July 2026), Python, PHP and Ruby (15).

No score change since it was listed.

### HubSpot API + MCP

- -0.1 on 8 October 2026: checklist

## 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.

**HubSpot API + MCP.** Remote MCP server GA since 13 April 2026, OAuth 2.1 with PKCE only. Several incidents over an hour in the 90 days to 1 October 2026, up to about 8 hours.

## 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

### HubSpot API + MCP

1. Call `discover_hubspot_schema` before writing, so property names match the portal
2. Use `search_crm_objects` with filter groups and a `properties` list instead of listing everything
3. Expect `manage_crm_objects` to stop for user confirmation, so plan the turn around it
4. Read `policyName` on a 429 to tell a 10-second burst from the daily cap
5. Ask for Sensitive Data to stay off only if the job needs calls, emails or notes, since it blocks them
