Assessment. Kraken pairs a documented REST, WebSocket and FIX API with the open-source kraken-cli, whose kraken-mcp server gates 33 dangerous tools behind approval and signs in by OAuth with a no-withdrawal key. Spot has no self-service sandbox, no OpenAPI file was found, and a 59-minute connectivity outage hit every interface on 30 October 2026.

Surface listed
The spot REST API at api.kraken.com and WebSocket v2 at ws.kraken.com/v2, with the derivatives API at futures.kraken.com and FIX, read from docs.kraken.com, support.kraken.com, kraken.com, status.kraken.com and a shallow clone of krakenfx/kraken-cli on 3 November 2026. No account was made and no MCP session was opened
MCP server
Official, local. kraken-mcp (stdio) ships with kraken-cli v0.5.1 and serves 152 tools in services (market 11, account 18, paper 17, workspace 20, futures-paper 17, feedback 1, trade 9, futures 39, earn 6, funding 10, subaccount 2, auth 2). Dangerous tools carry destructive_hint and ask for approval through MCP elicitation; clients without elicitation run them when the model sets acknowledged to true. Auth is the stored key or KRAKEN_API_KEY and KRAKEN_API_SECRET. Not in the official MCP registry
Key permissions
Query Funds, Deposit Funds, Withdraw Funds, Query Open Orders & Trades, Query Closed Orders & Trades, Modify Orders, Cancel/Close Orders, Query Ledger Entries, Export Data; optional Key Expiration, IP Address Restriction, nonce window and WebSocket interface. No withdrawal address allow-list was found in the key article. The OAuth-made key has no withdrawal rights
Rate limits
REST per key, Starter 15, Intermediate 20, Pro 20 counter points, decaying 0.33, 0.5 and 1 a second, ledger and trade history costing 2; matching engine per pair 60, 125 and 180 with 60, 80 and 225 open orders. Errors EAPI:Rate limit exceeded and EService:Throttled with a timestamp; no Retry-After header
Sandbox
Derivatives demo at demo-futures.kraken.com, self-service. Spot UAT sandbox on request through an account manager. Paper trading in kraken-cli at live prices with no account

Facts verified 3 November 2026 from vendor docs, repositories and package registries. JSON · Markdown

Strengths

  • Official local MCP server with 152 typed tools in services, destructive_hint on dangerous tools and an elicitation approval before each unless disabled
  • OAuth sign-in from the CLI mints a restricted spot key with no withdrawal rights that expires within 90 days, or a read-only key
  • Rate limits published with numbers by client tier for REST and the matching engine, shared across REST, WebSocket and FIX
  • Fees published without login, 0.40 per cent maker and 0.80 per cent taker at the lowest Pro tier, 0.02 and 0.05 on futures
  • Dated changelog of 120 entries with deprecations announced by date, a Statuspage site with API components and a valid security.txt

Weaknesses

  • No self-service spot sandbox; the spot UAT environment is on request through an account manager, and paper trading lives in the CLI
  • No OpenAPI file was found for the REST API; the machine-readable contract is the CLI's tool catalogue
  • Spot and derivatives clients could not connect or submit orders on any interface for 59 minutes on 30 October 2026
  • The CLI's feedback tool can upload a local file it names with no approval step, so the docs say to drop it for agents reading untrusted input
  • The terms bar bots, scripts and third-party applications on Kraken's content without written consent, alongside the documented API

Before you call it notes for agents

  1. 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. Test strategies in a paper workspace, which fills at live prices with no account, before a live workspace

Backed byHummingbird Ventures,SBI Group,Tribe Capital,Jane Street,DRW,HSG,Oppenheimer Alternative Investment Management,Citadel Securities

Researched 3 November 2026 from public pages. kraken.com/about names nobody and the legal hub names only Payward, Inc., so the founders and officers come from Wikipedia's Kraken article; Kraken's own press release naming Arjun Sethi co-CEO sits on Business Wire, which answered 403. Investors were looked for on kraken.com, payward.com's newsroom link and in three searches. Decrypt's report of 18 November 2025 names Jane Street, DRW Venture Capital, HSG, Oppenheimer Alternative Investment Management and Tribe Capital in an $800 million raise at a $20 billion valuation, with a separate $200 million from Citadel Securities; Reuters' headline names HSG and Jane Street in the September 2025 round, the article being paywalled. Wikipedia cites CNET and the Wall Street Journal for a $5 million Series A from Hummingbird Ventures and Bitcoin Opportunity Fund in March 2014 and SiliconANGLE for a Series B led by SBI Group in February 2016. Press reports say Payward filed a draft S-1 in November 2025 and has not listed; no first-hand filing was read, so the status is private. Shown for information, not part of the grade yet.

Score breakdown methodology v0.7 · October 2026 research run

Assessed on 3 November 2026 from public evidence, against the published checklist. Confidence medium. Performance and Task success are pending until our probes and task suites run, so the total is over the 7 assessed categories, each weight divided by 80.

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).

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).

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.

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).

Fix list 17 items, the biggest gain first

Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Kraken API. A fix counts at the next check, once it's public.

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.

Probe metrics

Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The live panel above has what the pollers have seen so far, which doesn't change the score.

Pricing & changes

Pay per use 0.4% fee The API costs nothing to call. Kraken Pro spot fees at the lowest 30-day volume tier are 0.40 per cent maker and 0.80 per cent taker, stablecoin, pegged token and FX pairs 0.20 per cent each way, and futures 0.02 per cent maker and 0.05 per cent taker. Public market data, paper trading in kraken-cli and the futures demo need no account.

For the vendor

Is this your product? Link to this page from your own site or README, then tell us where. It shows people and agents that the listing is yours and that you know it's here. It never changes a grade, rank or review.

  1. Add the badge or a link

    <a href="https://www.anchorterminal.com/tools/kraken"><img src="https://www.anchorterminal.com/badges/kraken.svg" alt="Kraken API on Anchor Terminal" height="20"></a>

    <a href="https://www.anchorterminal.com/tools/kraken">Kraken API on Anchor Terminal</a>

    It counts on a page on kraken.com or one of its subdomains, or the README at the root of github.com/krakenfx/kraken-cli.

  2. Tell us where it is

    We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.

Agents send the same to POST /api/v1/verify as {"slug": "kraken", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
