Four likely paths on developer.capsulecrm.com returned 404 and the docs link none. The MCP server's tool schemas sit behind OAuth and were not read (0 of 25). No llms.txt on either domain (0). Each of the 132 operations has a short description, and some say when to prefer another endpoint, such as filters over search (12 of 20). Parameter tables give types, ranges and defaults, and each resource has a model page, with filter conditions as JSON bodies (10 of 15). Request and response examples on every operation, and an errors page with bodies for 400, 401, 403, 422 and 429 (13 of 15). A `/api/v2` path and a dated changelog with five entries in the last 12 months (13 of 15).\n\n### Reliability: Capsule CRM +38\n\n- 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.\n- Capsule CRM (83): Graded on REST API v2, with the hosted lines. Status page at status.capsulecrm.com on Statuspage with Capsule and Drop Box components on its page and history back to 2023 in its feed (20). history.atom, read on 4 November, has no incident after 8 July 2026. The last, a minor delay to reports and dashboards, ran from 6 to 8 July 2026, a scheduled maintenance window was announced for 4 July, and a major outage of about 15 hours fell on 27 March 2026, all outside the 90 days from 6 August, and the page shows \"No incidents reported\" for each day to 4 November (30). The 8 October incident reading came from the page's /api/v2/incidents.json, which its robots.txt disallows, so it is struck and replaced by the feed. Limit published, 4,000 requests an hour per user (15). A 429 carries `X-RateLimit-Reset` and the docs say to wait until that time and suggest one second between calls, but there is no Retry-After header, no idempotency key and no safe-retry advice for writes (10 of 15). No SLA found, and the Customer Terms disclaim liability for unavailability (0). The REST API is generally available. The MCP server was announced on 25 September 2026 and the Claude connector is labelled beta on one support page (8 of 10). 20+30+15+10+0+8 = 83.\n\n### Maintenance \u0026 community: Breakcold +32\n\n- 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.\n- Capsule CRM (28): Last change on 25 September 2026, the hosted MCP server, 40 days before 4 November, and the changelog has no later entry (20, was 30, cause time). Two dated entries in the 90 days from 6 August, 19 August and 25 September 2026, which is short of three (0). A public changelog, a support address and a Google group for API questions. We did not test support (8 of 15). No official SDK, and the MCP server is not in the official MCP registry per the 8 October check (0). No packages to judge (0). 20+0+8+0+0 = 28.\n\n### Payments \u0026 pricing: Capsule CRM +15\n\n- 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.\n- Capsule CRM (30): No x402, MPP or L402 (0). Plans are public but priced per user, with nothing per call, and the pricing page draws the numbers by script. The Starter price of $18 and the $0 to $72 range came from Capsule's comparison pages (10). A Free plan for two users and 250 contacts and a 14-day trial with no card. Whether the Free plan includes the API was not found (20). A person signs up in a browser and creates the token, and registering an OAuth app needs a GitHub sign-in (0).\n\n### Security \u0026 auth: Breakcold +14\n\n- 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.\n- Capsule CRM (46): OAuth 2 authorisation code grant with scopes `read`, `write` and `user_preference`, access tokens of about seven days, refresh tokens and a revocation endpoint, per the authentication docs. The 8 October reading of the OAuth server metadata on api.capsulecrm.com came from the product's own endpoint and is struck. Personal tokens are also accepted on the REST API, and their scope is not documented. Tokens travel only in the header (24 of 30, partly met, kept). A `read` scope exists, and the MCP server acts with the connecting user's access controls. No server-side confirmation for writes was found, and the AI Terms put review of each tool call on the customer (12 of 20). Notes and stored emails reach the model, and no injection guidance was found (2 of 15). No API audit log was found, and the support page says MCP update tools keep no change history of their own (2 of 15). A reporting address (support+sensitive@capsulecrm.com), regular penetration tests by outside specialists per the security page and PCI-DSS for card collection. No security.txt, no bug bounty and no certification named on the pages read. The security page, re-read on 4 November, is unchanged, and security.txt still answers 404. The trust centre at trust.zestia.com is drawn by script and was not read (6 of 20).\n\n### Transparency \u0026 trust: Capsule CRM +9\n\n- 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.\n- Capsule CRM (76): Closed service with Customer Terms naming Zestia Limited, registered in England (15). The privacy policy of 21 August 2025, the DPA and the terms agree on a 14-day restore window after cancellation, deletion after that and backups for up to 50 days, with hosting on AWS in the United States. The AI Terms say inputs are not used to train models. The Claude connector page calls Anthropic a sub-processor, while the sub-processor list names OpenAI and not Anthropic (24 of 30). No deprecation policy. The changelog says Capsule tries to avoid breaking changes without notice, and the 19 August 2026 entry on the `pictureURL` change gives no date for the switch (8 of 20, partly met, kept; the changelog dates its entries, but the only notice with a switch date is the 2019 TLS change, so this isn't read as dated notices). Eleven sub-processors listed with location, transfer mechanism and safeguards, and 30 days' notice of changes in the DPA (17 of 20).\n\n## Score by category\n\n| Category | Weight | Breakcold | Capsule CRM | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 45 | 83 | Capsule CRM +38 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 90 | 48 | Breakcold +42 |\n| Agent ergonomics | 13% (16.2 this run) | 67 | 59 | Breakcold +8 |\n| Security \u0026 auth | 14% (17.5 this run) | 60 | 46 | Breakcold +14 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 15 | 30 | Capsule CRM +15 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 60 | 28 | Breakcold +32 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 67 | 76 | Capsule CRM +9 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **58 · C** | **54.9 · C** | |\n\n## Facts side by side\n\n| Fact | Breakcold | Capsule CRM |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Logike SAS | Zestia Limited |\n| Hosted endpoint | `https://mcp.breakcold.com/mcp/v1` | `https://api.capsulecrm.com/api/v2` |\n| Transports | Streamable HTTP | HTTP |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Paid | Freemium |\n| x402 | no | no |\n| Licence | none | Proprietary service under Capsule's Customer Terms |\n| Tools exposed | 72 | none |\n| Read-only variant documented | no | yes |\n| llms.txt | yes | no |\n| Last release | 2026-11-06 | 2026-09-25 |\n| Terms last updated | couldn't be read | no date given |\n| Privacy policy last updated | couldn't be read | 2025-08-21 |\n| Customer content may train models | couldn't be read | not found in the text |\n| Terms restrict automated access | couldn't be read | not found in the text |\n| Terms restrict benchmarking | couldn't be read | not found in the text |\n| Terms or service can change without notice | couldn't be read | yes |\n| Arbitration or class-action waiver | couldn't be read | not found in the text |\n\n## How the scores have moved\n\n### Breakcold\n\nNo score change since it was listed.\n\n### Capsule CRM\n\n- -0.9 on 4 November 2026: time\n- +0.1 on 27 October 2026: checklist\n\n## Verdicts\n\n**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.\n\n**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, the changelog's last entry is 25 September 2026, and the MCP server needs a Growth plan and a pre-registered OAuth app.\n\n## Before you call either\n\n### Breakcold\n\n1. Call `capabilities_list` or `tools_search` first to see which tools the granted scopes allow\n2. Send an Idempotency-Key on REST creates and a stable idempotency key on `records_create`, so retries return the original result\n3. Leave `sendMode` unset on compose and send tools until the user has confirmed the message\n4. Pass `fields` on record lists to cut the response to the fields you need\n5. On 429 wait for Retry-After or `retryAfterMs`; over MCP the error code is -32029\n\n### Capsule CRM\n\n1. Send `Authorization: Bearer \u003ctoken\u003e` to `https://api.capsulecrm.com/api/v2`. Projects use the old name in paths, `/kases`\n2. Follow the `Link` header for the next page. `perPage` goes up to 100 and the default is 50\n3. On 429, wait until the epoch time in `X-RateLimit-Reset`. The docs suggest one second between calls\n4. Ask for the `read` scope when the task only reads. A write with a read-only token answers 403 with `insufficient_scope`\n5. 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\n\n## Questions\n\n### Which is better for AI agents, Breakcold or Capsule CRM?\n\nBreakcold scores 58 (C) on agent readiness against Capsule CRM's 54.9 (C), and leads in 4 of 7 scored categories. Capsule CRM leads on reliability, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Breakcold and Capsule CRM need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Breakcold and Capsule CRM without installing anything?\n\nYes. Breakcold has a hosted endpoint at https://mcp.breakcold.com/mcp/v1 and Capsule CRM at https://api.capsulecrm.com/api/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/breakcold-vs-capsule-crm.json, and with the fewest tokens: https://www.anchorterminal.com/compare/breakcold-vs-capsule-crm.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"breakcold\", \"b\": \"capsule-crm\"}`.
