Abyssale vs Canva REST APIs + MCP

Abyssale 41

Hosted lines, for the REST API and the remote MCP server. No status page was linked from the site or the docs, and status.abyssale.com did not answer (0). No readable incident history (5). Rate limits published in full, 10 requests a second globally and per-workspace tiers with per-minute and per-hour budgets (15). 429s carry Retry-After and X-RateLimit headers, three 429 ids say which limit was hit, failed generations cost nothing, and webhooks carry a delivery id to deduplicate on. No idempotency key on generation requests (13 of 15). The terms promise best-effort availability and leave SLAs to Enterprise contracts, so none is published (0). Generation and the MCP server are generally available, while Design Import, the JSON authoring route, is labelled alpha (8 of 10). 0 + 5 + 15 + 13 + 0 + 8 = 41.

Canva REST APIs + MCP 79

Atlassian Statuspage at canvastatus.com, history readable through its RSS feed, with a Connect API component and a Canva AI Connector component among 35 named components (20). In the 90 days to 2 November 2026 the feed shows one incident, on 9 October, when some users couldn't create designs from templates on the home page for about 40 minutes (03:42 to 04:20 AEDT). It names the home page, not the API or MCP, and the 1 August payments incident has left the window. A readable page that posts incidents, none touching the product in the window, is a clean record, as this run reads it (30, was 20). Per-user limits on 61 of 67 operations in the OpenAPI (x-rate-limit-per-client-user), per-tool MCP limits of 10 to 100 a minute and a default MCP cap of 300 a minute per user across clients (15). 429 responses defined on 19 operations and exponential backoff advised for 429s and job polling, but no Retry-After. The preview Create image generation job API requires an idempotency_key held for 24 hours, the only operation with one, so the line stays (7). No SLA found (0). Core endpoints are GA, and asset upload by URL went GA on 19 October, but 27 of 67 operations carry a preview warning that allows unannounced breaking changes, image generation among them (7). 20+30+15+7+0+7 = 79.

20 MCP tools (15 for 11 to 30), plus 5 because OAuth scopes per tool group let a client be approved for reads only (20 of 25). Design listings search by words in any order, filter by project, orientation, size, format and dates, sort and order, and say honestly when a page is past the end; listing tools refuse unsupported options rather than ignore them, per MCP 1.2.0 (19 of 20). One envelope with an id to branch on, and error docs that say which errors a retry never fixes (19 of 20). The permissions page marks each tool read-only, mutating or destructive, but MCP annotations couldn't be confirmed on the closed server, and generation has no idempotency key (12 of 20). Official Node.js and Python SDKs with retry behaviour and polling helpers (15). 20 + 19 + 19 + 12 + 15 = 85.

Canva REST APIs + MCP 59

46 MCP tools on 24 October and 2 November (33 on 1 October) with no toolsets or dynamic loading (5), and REST lists take a limit (5). Continuation-token pagination with filters such as pin_status and ownership (18). Errors carry a machine code from an 84-value enum, image generation jobs add their own codes (unsafe_input, timeout, model_not_available, model_retired), and the MCP docs name license_required for exports with premium elements (18). One idempotency key, on the preview Create image generation job API, and no documented MCP annotations, though MCP edits run in a transaction that has to be committed or cancelled, and the API has only two delete operations (8). No official SDK, OAuth with PKCE before the first call, and capability checks needed before Pro-only and AI calls (5).

Closed service under terms of service version 3 of 21 July 2026, from a Paris SAS with its register number (15). The privacy policy and terms agree on EU hosting on AWS Ireland, deletion timelines and breach notice within 72 hours, but AI model training on anonymised customer content is on by default with a workspace opt-out, and anonymised data may be kept indefinitely (20 of 30). The changelog has Deprecated and Removed sections and refers to a deprecation policy that covers stable endpoints but not alpha ones; the policy's notice period wasn't found (14 of 20). Subprocessors named with locations, among them AWS Ireland, Auth0, Brevo, Intercom and AI providers including OpenAI, Anthropic, Black Forest Labs and Google, some outside the EEA (20). 15 + 20 + 14 + 20 = 69.

Canva REST APIs + MCP 83

Closed service under published terms (15). Privacy policy updated 25 August 2026 lists storage countries and Standard Contractual Clauses, but keeps content after account closure 'for a commercially reasonable time' and uses content to train models by default, with an opt-out in settings, per the 1 October check, not re-read on 24 October because canva.com's robots.txt disallows our fetcher (18). Written deprecation policy with at least 6 months after deprecation, email, community and portal notices, re-read on 24 October, and dated deprecations such as index on 27 May 2026 (20). Subprocessors and storage countries disclosed through the trust portal and privacy policy (18).

The MCP server uses OAuth through Auth0 with scopes per tool group (read:design, write:design, delete:design, import:design, generate:banner, read:credits and others), enforced alongside the user's workspace role, and approval is per client connection. The REST API uses a workspace x-api-key with no scopes documented (28 of 30). A client can be approved for reads only, and deleting needs its own scope, but nothing on the server asks for confirmation; the docs leave that to the client per the MCP spec (17 of 20). Tools return the workspace's own designs and fonts; image layers can point at outside URLs (10 of 15). No audit log or per-call record was found (0). No security.txt, disclosure policy, bug bounty or certification found (0). 28 + 17 + 10 + 0 + 0 = 55.

Canva REST APIs + MCP 63

OAuth 2.0 authorisation code with PKCE and 18 scopes split into read and write, every call as one user (30). Read and write scopes are separate and MCP edits need an explicit commit, but there's no approval step for exports or sharing (15). Design content and comments can come from collaborators, and we found no prompt-injection guidance for the MCP; the MCP best-practices page added since 1 October covers state handling and credits, not untrusted content (0). No per-call audit log found (0). security.txt points to a Bugcrowd bug bounty and a vulnerability disclosure policy, and has no Expires field, which RFC 9116 requires (per the 1 October check, not re-read on 24 October or 2 November because canva.com's robots.txt disallows our fetcher). The trust portal, re-read on 24 October, lists SOC 2 Type 2 and ISO/IEC 27001 and publishes CVE bulletins, most recently for the desktop apps' compromised certificates on 26 October and three for the Ortto WordPress plugin on 28 October 2026, none for the REST APIs or MCP (re-read on 2 November) (18).

No x402, MPP or L402 (0). Seat prices are public and the credit cost of every output is published to the format, with worked examples, but a credit's price outside the plan wasn't found (15 of 20). 14-day free trial with no card (20). A person signs up in the browser; the MCP OAuth flow needs a human login (0). 0 + 15 + 20 + 0 = 35.

Canva REST APIs + MCP 30

No x402, MPP or L402 (0). No API fee. What the API can do follows the user's Canva plan, whose prices are public per the 1 October check (canva.com's robots.txt disallows our fetcher on 24 October) (10). Canva Free reaches generation, editing, export and asset upload with no card, and the MCP tools page lists generate-image on all plans (20). Image generation, image transformation and design generation draw on the user's AI credit allowance. When it runs out, image generation returns 429 credit_quota_exceeded, and design generation has returned a 402 since 28 October. A person has to sign in and approve OAuth in a browser, and integrators register in the Developer Portal (0).
