Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 67 | 13.4 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 80 | 13.0 | | Agent ergonomics | 13% | 16.2 | 79 | 12.8 | | Security & auth | 14% | 17.5 | 80 | 14.0 | | Payments & pricing | 10% | 12.5 | 40 | 5.0 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 81 | 7.1 | | Transparency & trust (editorial 36, provenance 94) | 7% | 8.8 | 65 | 5.7 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **71 → BB** | ### Why each score - Reliability 67 (checked 2026-11-03): Read with the hosted lines on the spot API. status.kraken.com is a Statuspage site with REST, WebSocket and FIX components (20). The incidents feed read covers 4 September to 3 November 2026. On 30 October spot and derivatives clients could not connect or submit orders across web, mobile, REST, WebSocket and FIX for 59 minutes 39 seconds, rated minor by Kraken; on 28 October some FIX clients were rejected on reconnection for 1 hour 59 minutes while other interfaces worked; the futures engine was degraded for 3 minutes on 13 October. A whole-exchange order outage 21 seconds short of an hour is read as one major (10 of 30). Numeric limits per key by tier and per pair for the matching engine (15). EAPI:Rate limit exceeded and EService:Throttled with a retry timestamp, a client order id and a validate flag on orders, but no Retry-After header (12 of 15). No SLA (0). Generally available (10). 20 + 10 + 15 + 12 + 0 + 10 = 67. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 80 (checked 2026-11-03): No OpenAPI file was found for the REST API in the docs read; the CLI's agents/tool-catalog.json gives JSON Schema inputs for all 188 commands and the 152 MCP tools (15 of 25). The docs serve Markdown twins such as quickstart.md and the CLI ships llms.txt, AGENTS.md and CONTEXT.md (10). Endpoint pages and guides on order lifecycle, errors and rate limits say what each call does, with less on when not to use one (15 of 20). Enums for order types, time in force and flags, and enums and required fields in the tool catalogue (12 of 15). Python, Node.js and cURL examples, an errors guide and the CLI's error-catalog.json with retry guidance (13 of 15). A changelog of 120 dated entries with deprecations dated (15). 15 + 10 + 15 + 12 + 13 + 15 = 80. - Agent ergonomics 79 (checked 2026-11-03): The MCP server loads services with -s, defaults to no live trading, and its 152 tool definitions average about 520 characters; the REST API takes count, limit and pair filters but has no field selection (18 of 25). Cursor pagination on ledgers and trades since 30 September and 6 October 2026, with ofs deprecated (17 of 20). Prefixed error strings such as EOrder:Rate limit exceeded and EAPI:Invalid nonce, and the CLI's error catalogue says which to retry (17 of 20). cl_ord_id and validate on orders, destructive_hint and elicitation on dangerous MCP tools, no idempotency key on REST (16 of 20). An official Rust SDK at 5 stars, a Go module and example clients, HMAC-SHA512 signing with a strict nonce (11 of 15). 18 + 17 + 17 + 16 + 11 = 79. - Security & auth 80 (checked 2026-11-03): Keys with nine named permissions, optional expiry, IP restriction and nonce window, plus an OAuth sign-in from the CLI (authorisation code with PKCE, public client) that mints a no-withdrawal key expiring within 90 days or a read-only key (30). Read-only and no-withdrawal keys, position limits and pair allowlists in account settings, and MCP approval prompts for 33 dangerous tools (18 of 20). The API returns no untrusted content; the CLI docs warn that the feedback tool uploads a local file without approval (10). Keys and their permissions are listed in settings and ledgers record activity, but no per-call log for the operator was found (6 of 15). A valid security.txt, a bug bounty policy page, SECURITY.md and a secure SDLC workflow in the CLI; certifications not read (16 of 20). 30 + 18 + 10 + 6 + 16 = 80. - Payments & pricing 40 (checked 2026-11-03): No machine payment protocol (0). Maker and taker fees by tier published without login (20). Public market data, paper trading and the futures demo need no account or card (20). A person signs up, verifies and mints a key or approves the OAuth sign-in (0). 0 + 20 + 20 + 0 = 40. - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 81 (checked 2026-11-03): Read as a closed service with an open-source client. Changelog entry of 27 October 2026 and kraken-cli v0.5.1 on 29 October (30). Fourteen changelog entries since 19 August 2026 and CLI tags on 6 and 7 August and 28 and 29 October (20). A public changelog, api@kraken.com, a status page and a CLI repository merging pull requests at the end of October; issue replies not read (11 of 15). An official Rust SDK pushed in October 2026 and a Go module from January; the MCP server is not in the official registry (12 of 15). The CLI has release and secure SDLC workflows, deny.toml and a pinned toolchain; the SDK's CI not read (8 of 10). 30 + 20 + 11 + 12 + 8 = 81. - Transparency & trust 65 (checked 2026-11-03): The editorial half. A closed service with clear terms naming regional Payward entities under California law; the CLI is MIT (15 of 30). The privacy notice was not read (5 of 30). The changelog dates deprecations and the terms carry a last-updated date (16 of 20). No subprocessor or data-location statement read (0 of 20). 15 + 5 + 16 + 0 = 36. Fix list, everything this grade says the listing lacks, the biggest gain first (17 items). What it covers is at https://www.anchorterminal.com/fixes/kraken.md (JSON https://www.anchorterminal.com/fixes/kraken.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{"listing": "kraken", "plan": "read"}`, free while the beta runs ### What we couldn't check - Kind http-api, not mcp. The MCP server is a local route built on the same API and is alpha by its own README; the REST, WebSocket and FIX APIs carry the docs, limits and status components. - Judgement call on the incident record. The 30 October 2026 connectivity outage lasted 59 minutes 39 seconds across every trading interface and Kraken rated it minor; it is scored as one major because the whole exchange could not take orders for about an hour. Incidents from 5 August to 3 September 2026 were beyond the feed we could read. - unchecked: the privacy notice, an OpenAPI file for the REST API (none found in the pages read), kraken-api-sdk's CI and the issue queues. - unchecked: the live kraken-mcp tool definitions as served; counts and annotations come from the CLI's tool catalogue and docs. - firstReleased is 28 November 2018, the oldest entry in the API changelog (WebSocket v1 sandbox); the REST API is older and Kraken launched in 2011. - The terms' bar on bots, scripts and third-party applications on Kraken's content sits beside a documented API, a CLI built for agents and an OAuth sign-in for it. Recorded as a fact, not deducted. - Humans. kraken.com/about names nobody; the co-CEO and chairman roles rest on Wikipedia, as Kraken's own press release on Business Wire answered 403. ### Sources - robots.txt (docs.kraken.com, www.kraken.com, support.kraken.com): (seen 2026-11-03) - developer docs landing page: (seen 2026-11-03) - exchange APIs overview (hosts, FIX, demo, UAT): (seen 2026-11-03) - REST rate limits by tier: (seen 2026-11-03) - matching engine rate limits: (seen 2026-11-03) - REST authentication (HMAC-SHA512, nonce): (seen 2026-11-03) - API changelog (120 entries, 28 November 2018 to 27 October 2026): (seen 2026-11-03) - MCP server docs: (seen 2026-11-03) - kraken-cli repository, shallow clone (README, CHANGELOG, tool catalogue, tags, workflows): (seen 2026-11-03) - kraken-cli releases (v0.5.0 and v0.5.1): (seen 2026-11-03) - GitHub organisation repositories: (seen 2026-11-03) - API key permissions article: (seen 2026-11-03) - where Kraken is licensed or regulated (prohibited regions): (seen 2026-11-03) - fee schedule: (seen 2026-11-03) - legal hub: (seen 2026-11-03) - Global Terms of Service (30 October 2026): (seen 2026-11-03) - status incidents feed (4 September to 3 November 2026): (seen 2026-11-03) - security.txt: (seen 2026-11-03) - about page: (seen 2026-11-03) - official MCP registry search: (seen 2026-11-03) - RDAP for kraken.com: (seen 2026-11-03) ## Score history Every move of a score since the listing was graded, newest first, with its cause.

Start kraken-mcp with -s market,paper,feedback or the default services; add trade only with a least-privilege key, and never pass --allow-dangerous on an agent that reads untrusted input 2. Ask the person to run kraken auth login in their own terminal; it needs a browser and saves a no-withdrawal key that expires in 90 days at most 3. Send a fresh --cl-ord-id on each order and run it with --validate first; after a network error look the order up before sending it again 4. Keep the nonce strictly increasing per key and stay under the tier's counter, since EAPI:Rate limit exceeded has no Retry-After header 5.

It serves 152 of the CLI's 188 commands as tools, grouped in services chosen with -s (default market, account, paper, workspace, feedback); 33 tools are marked dangerous with destructive_hint and need an elicitation approval unless --allow-dangerous is passed. It is not exposed over the network and is not in the official MCP registry, where Kraken entries are third-party under io.github namespaces (source: ) - agents/tool-catalog.json in kraken-cli is a machine-readable catalogue of the 188 commands with JSON Schema inputs, a dangerous flag, an effect field and a reach field saying which are MCP tools; the 152 tool definitions total about 80,000 characters (source: ) - REST rate limits per key by client tier, Starter 15, Intermediate 20 and Pro 20 counter points decaying at 0.33, 0.5 and 1 a second, and matching-engine limits per pair of 60, 125 and 180 with 60, 80 and 225 open orders (source: ) - FIX 4.4 for spot and derivatives with cancel-on-disconnect and colocation; a derivatives demo at demo-futures.kraken.com is self-service and a spot UAT sandbox is available on request through an account manager (source: ) - status.kraken.com is a Statuspage site with REST, WebSocket and FIX components. On 30 October 2026 spot and derivatives clients could not connect or submit orders across web, mobile, REST, WebSocket and FIX for 59 minutes 39 seconds, and on 28 October some FIX clients were rejected on reconnection for 1 hour 59 minutes (source: ) - The API changelog has 120 dated entries from 28 November 2018 to 27 October 2026, with deprecations dated (fee fields on AssetPairs on 8 September, ofs and other parameters on 30 September and 6 October 2026) (source: ) - The Global Terms of Service of 30 October 2026 bar bots, scripts, scraping and third-party applications that interact with Kraken's content without written consent, while naming API access as a way to place trades (source: ) - Kraken does not serve Afghanistan, Belarus, Crimea, Donetsk and Luhansk, Cuba, the Democratic Republic of the Congo, Iran, Iraq, Japan, Libya, North Korea, Russia, Sudan, South Sudan or Syria, nor residents of Maine or New York (source: ) - security.txt names bugbounty@kraken.com and a bug bounty policy page, expiring 13 February 2027 (source: ) - #2 of 21 in Best crypto exchange APIs and MCP servers for AI agents: https://www.anchorterminal.com/best/crypto-exchanges/index.md - All 210 exchanges comparisons: https://www.anchorterminal.com/compare/crypto-exchanges/index.md ## Compare - [Bitfinex API vs Kraken API](https://www.anchorterminal.com/compare/bitfinex-vs-kraken.md): C 58.4 vs BB 71 - [Bitget vs Kraken API](https://www.anchorterminal.com/compare/bitget-vs-kraken.md): D 53.9 vs BB 71 - [Bithumb Open API vs Kraken API](https://www.anchorterminal.com/compare/bithumb-vs-kraken.md): D 50.6 vs BB 71 - [Bitstamp API vs Kraken API](https://www.anchorterminal.com/compare/bitstamp-vs-kraken.md): D 50.4 vs BB 71 - [Bybit vs Kraken API](https://www.anchorterminal.com/compare/bybit-vs-kraken.md): C 57.3 vs BB 71 - [Crypto.com Exchange API vs Kraken API](https://www.anchorterminal.com/compare/crypto-com-exchange-vs-kraken.md): D 46.8 vs BB 71 - [Gate vs Kraken API](https://www.anchorterminal.com/compare/gate-io-vs-kraken.md): C 56.4 vs BB 71 - [Gemini Exchange API vs Kraken API](https://www.anchorterminal.com/compare/gemini-exchange-vs-kraken.md): BB 74.6 vs BB 71 - [HTX trading API vs Kraken API](https://www.anchorterminal.com/compare/htx-vs-kraken.md): E 43.3 vs BB 71 - [Binance API vs Kraken API](https://www.anchorterminal.com/compare/binance-vs-kraken.md): B 63.2 vs BB 71 - [Coinbase Advanced Trade API vs Kraken API](https://www.anchorterminal.com/compare/coinbase-advanced-trade-vs-kraken.md): C 61.7 vs BB 71 - [Coinbase MCP server (Coinbase for Agents) vs Kraken API](https://www.anchorterminal.com/compare/coinbase-mcp-vs-kraken.md): C 60 vs BB 71 - [Kraken API vs KuCoin](https://www.anchorterminal.com/compare/kraken-vs-kucoin.md): BB 71 vs D 53.9 - [Kraken API vs MEXC API](https://www.anchorterminal.com/compare/kraken-vs-mexc.md): BB 71 vs C 56.3 - [Kraken API vs OKX API](https://www.anchorterminal.com/compare/kraken-vs-okx.md): BB 71 vs B 64.3 - [Kraken API vs Uniswap Trading API](https://www.anchorterminal.com/compare/kraken-vs-uniswap.md): BB 71 vs B 63.3 - [Kraken API vs Upbit Open API](https://www.anchorterminal.com/compare/kraken-vs-upbit.md): BB 71 vs C 54.7 - [Deribit vs Kraken API](https://www.anchorterminal.com/compare/deribit-vs-kraken.md): C 59 vs BB 71 - [dYdX vs Kraken API](https://www.anchorterminal.com/compare/dydx-vs-kraken.md): B 69.5 vs BB 71 - [Hyperliquid vs Kraken API](https://www.anchorterminal.com/compare/hyperliquid-vs-kraken.md): D 50 vs BB 71 ## Verify this listing For the vendor. The badge or a plain link to this page verifies the listing, from a page on kraken.com or one of its subdomains, or the README at the root of github.com/krakenfx/kraken-cli. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "kraken", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
