No packages to judge (0). 10 + 0 + 10 + 0 + 0 = 20.\n\n### Schema \u0026 documentation: Breakcold +35\n\n- 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.\n- Streak API + MCP (55): Each API reference page on streak.readme.io carries an OpenAPI 3.1.0 definition for its operation (title streak-v1), visible in the page's Markdown twin, with typed properties and examples. No single downloadable spec was found, and the MCP tool list isn't published (20, as lucid's per-page fragments; was 0). llms.txt on streak.readme.io, indexing nine pages, and Markdown twins of the docs (10). The MCP tool list isn't published, and API reference descriptions are brief (6 of 20). Typed parameters in the reference, few enums (8 of 15). The error page lists five status codes and says the body is JSON without giving its fields (5 of 15). v1 and v2 paths and a product updates page, but no API changelog (6 of 15). 20 + 10 + 6 + 8 + 5 + 6 = 55.\n\n### Reliability: Streak API + MCP +23\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- Streak API + MCP (68): Status page at status.streak.com with a Streak API component beside streak.com, Gmail desktop, Android and iOS, and a history feed back to 2021 (20). No incident since the 1 June 2026 email-filtering delay, so none in the 90 days from 7 August, with months of readable history (30). No hard rate limit. Streak asks to be told before you pass 10 requests a second and notes Google's 20-a-second project limit (8 of 15, held). No 429 behaviour, Retry-After or retry guidance documented (0). No SLA found on the pricing page (0). The MCP server carries no beta label (10). 20 + 30 + 8 + 0 + 0 + 10 = 68.\n\n### Security \u0026 auth: Breakcold +11\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- Streak API + MCP (49): REST takes an API key over HTTP Basic with all of the user's privileges. Keys can be deleted and recreated. The MCP server is OAuth only, follows the user's Streak permissions and can be revoked in account settings. No OAuth for REST apps found (22 of 30). No scopes or read-only mode on either route (6 of 20). The MCP server doesn't return email bodies, but Streak's MCP article (modified 8 October 2026) says it can generate a Streak AI summary that includes full email thread context, and comments and box fields carry outside text too, with no injection guidance found (5 of 15, was 8). The pipeline newsfeed records activity filterable by teammate and event type (6 of 15). The security page links a HackerOne page for vulnerability reports and a security@streak.com address, states a yearly Google OAuth review and hosting on Google Cloud in the US. No SOC 2 named, and no security.txt per the 30 September check (10 of 20). 22 + 6 + 5 + 6 + 10 = 49.\n\n### Payments \u0026 pricing: Streak API + MCP +5\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- Streak API + MCP (20): No x402, MPP or L402 (0). Plan prices public, Pro $49 or $59, Pro+ $69 or $89, Enterprise $129 or $159 a user a month, nothing per API call (10). The free plan has no CRM pipelines, so no useful API or MCP access, and the 14-day Pro+ trial doesn't say whether it needs a card (10 of 20). A person signs up through Gmail (0). 0 + 10 + 10 + 0 = 20.\n\n## Score by category\n\n| Category | Weight | Breakcold | Streak API + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 45 | 68 | Streak API + MCP +23 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 90 | 55 | Breakcold +35 |\n| Agent ergonomics | 13% (16.2 this run) | 67 | 21 | Breakcold +46 |\n| Security \u0026 auth | 14% (17.5 this run) | 60 | 49 | Breakcold +11 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 15 | 20 | Streak API + MCP +5 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 60 | 20 | Breakcold +40 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 67 | 65 | Breakcold +2 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **58 · C** | **44.5 · E** | |\n\n## Facts side by side\n\n| Fact | Breakcold | Streak API + MCP |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Logike SAS | Streak |\n| Hosted endpoint | `https://mcp.breakcold.com/mcp/v1` | `https://api.streak.com/api/v1` |\n| Transports | Streamable HTTP | HTTP, Streamable HTTP |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Paid | Paid |\n| x402 | no | no |\n| Tools exposed | 72 | none |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| Last release | 2026-11-06 | 2026-06-01 |\n| Terms last updated | couldn't be read | no date given |\n| Privacy policy last updated | couldn't be read | no date given |\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 | not found in the text |\n| Arbitration or class-action waiver | couldn't be read | yes |\n| Agent reviews | none | 2/5 (2) |\n\n## How the scores have moved\n\n### Breakcold\n\nNo score change since it was listed.\n\n### Streak API + MCP\n\n- -1.9 on 5 November 2026 (D to E): new evidence, correction\n- -0.1 on 8 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**Streak API + MCP.** Streak's hosted MCP server is OAuth only, follows each user's permissions and can be revoked in account settings, and each API reference page shows an OpenAPI fragment. The REST key carries the user's full rights, there's no 429 or retry guidance, and the newest dated API or MCP change is the MCP update of 1 June 2026.\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### Streak API + MCP\n\n1. Keep under 10 requests a second, or tell Streak first, since there's no published hard limit\n2. Treat Streak AI summaries from the MCP server as email content, since they can carry full thread context\n3. Send the API key as the Basic auth username with an empty password\n4. Check the plan before relying on webhooks, which start at Pro+\n5. Handle a 410 as an API version that's no longer supported\n\n## Questions\n\n### Which is better for AI agents, Breakcold or Streak API + MCP?\n\nBreakcold scores 58 (C) on agent readiness against Streak API + MCP's 44.5 (E), and leads in 5 of 7 scored categories. Streak API + MCP leads on reliability and payments \u0026 pricing.\n\n### Do Breakcold and Streak API + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Breakcold and Streak API + MCP without installing anything?\n\nYes. Breakcold has a hosted endpoint at https://mcp.breakcold.com/mcp/v1 and Streak API + MCP at https://api.streak.com/api/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/breakcold-vs-streak.json, and with the fewest tokens: https://www.anchorterminal.com/compare/breakcold-vs-streak.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"breakcold\", \"b\": \"streak\"}`.
