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.
Maintenance & community Relaticle +30
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.
Relaticle 90
v3.8.2 tagged on 5 November 2026 and commits on 6 November (30). Thirteen tags between 9 October and 5 November alone (20). More than 2,500 commits since 1 August and merged pull requests numbered past 1,100; the GitHub API did not answer, so open issues and reply times were not counted (15 of 25). Verified com.relaticle/crm namespace in the official MCP registry with the hosted remote (15). CI, tests, security-audit and Dependabot workflows, PHP 8.5 and Laravel 13 (10). 30 + 20 + 15 + 15 + 10 = 90.
Payments & pricing Relaticle +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.
Relaticle 30
No x402, MPP or L402 (0). Cloud prices are public per workspace with nothing per call (10). A 14-day Cloud Pro trial with no card, and self-hosting is free (20). A person signs up in a browser behind a Cloudflare check, or deploys a server (0). 0 + 10 + 20 + 0 = 30.
Agent ergonomics Breakcold +8
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.
Relaticle 59
50 MCP tools, six schema resources and a prompt, with no toolsets or read-only subset (5). Filters combine native fields, custom fields and linked records with $and, $or and $not, plus sort, include, per_page (MCP maximum 25) and cursors (20). Errors come back as HTTP codes and inline MCP error responses such as Invalid ability provided.; no error catalogue was read (12 of 20). Base tool classes set readOnlyHint, destructiveHint, idempotentHint and openWorldHint, and upserts by unique field make creates safe to retry (17 of 20). One URL with OAuth or a token; no official SDK (5 of 15). 5 + 20 + 12 + 17 + 5 = 59.
Transparency & trust Relaticle +6
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.
Relaticle 73
AGPL-3.0 source with an integration exception, and terms for the Cloud service (30). The privacy policy (4 November 2026) gives retention for server logs (90 days), contact forms (12 months) and paused trial workspaces (deleted after 60 days with notice), and names provider categories; no DPA was found (20 of 30). No deprecation policy or dated notices found (5 of 20). The security page lists each Cloud provider and what it receives, with hosting at Hetzner in Germany, and website analytics through Fathom without CRM content (17 of 20). 30 + 20 + 5 + 17 = 72.
Reliability Breakcold +5
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.
Relaticle 40
Graded with the hosted lines on Relaticle Cloud's REST API and MCP server, the surface an outside agent calls; the software also self-hosts. No status page is linked and status.relaticle.com did not connect (0). With no readable history the incident line scores 5. Limits have numbers: 600 a minute per workspace and 300 reads or 60 writes a minute per token in the source, and 120 MCP calls a minute per user in the docs (15). 429 is in the OpenAPI responses and upserts by unique field give a safe retry for creates, but the backoff guidance sits on a docs section we read only as a heading (10 of 15). No SLA (0). Version 3.8, not labelled beta (10). 0 + 5 + 15 + 10 + 0 + 10 = 40.

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.
Relaticle
Relaticle is an actively released AGPL CRM whose REST API and MCP server have an OpenAPI spec, annotated tools, workspace-bound tokens with per-method permissions and a free self-hosted route. MCP writes apply at once with no server-side confirmation, OAuth grants the whole toolset, and Cloud has no status page, SLA or certification.
Before you call either
Breakcold
- Call
capabilities_listortools_searchfirst to see which tools the granted scopes allow - Send an Idempotency-Key on REST creates and a stable idempotency key on
records_create, so retries return the original result - Leave
sendModeunset on compose and send tools until the user has confirmed the message - Pass
fieldson record lists to cut the response to the fields you need - On 429 wait for Retry-After or
retryAfterMs; over MCP the error code is -32029
Relaticle
- Use a personal access token with only the read permission unless the task writes, since OAuth grants every tool
- Ask the user before create, update, delete or send tools; the server applies them at once
- Call
get-crm-schema-toolfor an entity before filtering on custom fields, which differ by workspace - Use
POST /v1/people/upsertor/v1/companies/upsertwith a unique field to avoid duplicates on retry - Keep MCP calls under 120 a minute per user and REST writes under 60 a minute per token on Cloud Pro
