Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Reliability Zoho CRM +27

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.

Zoho CRM 72

Graded on the REST API v8, read as a hosted service. status.zoho.com redirects to us.zohostatus.com, which has a Zoho CRM component and incident history back to December 2025 (20). From 3 August to 1 November the history lists 21 incidents across Zoho services, most of them a few minutes long. One touches CRM: on 24 October a multi-service outage ("Qntrl and a few other components") ran 16 minutes 16 seconds, and the status feed shows the Zoho CRM component returning to Operational at 18:12 IST within it. On 3 September a Zoho Deluge outage ran 2 hours 34 minutes, and the CRM component's state changed when it ended. Both read as partial, so minor incidents only (20 of 30). Only the US page was read. Daily credits and concurrency are published with numbers per edition (15). 429 is documented and X-API-CREDITS-REMAINING appears once half the allowance is used, but no Retry-After or backoff guidance was found. Upsert and If-Unmodified-Since make writes safer to retry (7 of 15). No SLA found (0). v8 is the current documented version (10).

Payments & pricing Zoho CRM +25

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.

Zoho CRM 40

No x402, MPP or L402 (0). Edition prices are public, $14 to $52 a user a month billed yearly, and extra API credits have a published unit price from $0.14 per 1,000 a day (20). The Free edition covers three users with 5,000 API credits a day and needs no card at signup (20). A person signs up in a browser, registers an OAuth client in the API console and approves scopes (0).

Maintenance & community Zoho CRM +17

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.

Zoho CRM 77

The Node.js SDK for v8 reached 5.0.0 on 15 October 2026 (30). Three dated changes from 3 August to 1 November, the OpenAPI files on 2 September, Node.js SDK 4.0.0 on 21 September and 5.0.0 on 15 October. Python SDK 7.0.0 of 24 July has left the window (20). No dated API changelog. The docs link to community posts on help.zoho.com, which we did not test for replies (8 of 25). Current official SDKs for Java, Python, PHP, Node.js, C# and Ruby (15). The SDK repositories show no public CI, and the Java SDK was last released on 7 January 2026 and the Ruby SDK on 16 April 2025 (4 of 10).

Agent ergonomics Zoho CRM +14

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.

Zoho CRM 81

Graded on the REST API. fields is mandatory on list calls with at most 50 names, and COQL selects columns, so responses can be kept small (22 of 25). per_page up to 200, page to 2,000 records and page_token to 100,000, plus search by criteria, email, phone or word, custom views and COQL (20). Errors carry a code, a message and details naming the field or the existing record, each documented with a resolution (18 of 20). Upsert on duplicate check fields and If-Unmodified-Since, with no idempotency key (10 of 20). Official SDKs in six languages, but the one-hour token, the refresh step and per-data-centre hosts add setup (11 of 15).

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.

Zoho CRM 81

zoho/crm-oas on GitHub holds OpenAPI 3.1 files for 103 resources and 644 operations (25). No llms.txt at zoho.com, but the same repository carries a compressed Markdown page and examples per operation, written for Zoho's CRM agent skills (7 of 10). Operation descriptions state the purpose and name the call that supplies each ID, with little on when not to use one (15 of 20). Parameters carry enums, patterns and length limits. Record bodies accept any property because modules have custom fields, and search criteria are a string grammar (11 of 15). Each reference page has curl samples and a Possible Errors list with a resolution per code (15). The version is in the path, and What's New in V8 lists changes without dates. No dated changelog found (8 of 15).

Transparency & trust Zoho CRM +8

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.

The DPA is sent on request by email (24 of 30). No API deprecation policy or dated notices found (0). A sub-processor page exists, but its directory loads by script and we could not read the list. The data centre page names locations and their certifications (15 of 20).

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.

Zoho CRM

A public OpenAPI 3.1 description of 644 operations and OAuth scopes down to one module and one operation suit agent use, and the Free edition includes 5,000 API credits a day. The documented token refresh puts the client secret in the URL, and no SLA, deprecation policy or dated API changelog was found.

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

Zoho CRM

  1. Use the api_domain returned with the token, since each data centre has its own host (zohoapis.com, zohoapis.eu, zohoapis.in and others)
  2. Send Authorization: Zoho-oauthtoken <token> and refresh hourly. Put refresh parameters in the POST body, not the URL
  3. Pass fields on every list call. Page with page up to 2,000 records, then page_token up to 100,000
  4. Create through /{module}/upsert so a retry updates instead of duplicating
  5. Budget credits. Convert Lead costs 5, Send Mail 20, a bulk read 50, and calls through the MCP servers draw on the same allowance
