Which one, for what

Bitstamp API D

Best for An agent that needs a long-running regulated spot venue in the EU, UK and US with a sandbox and per-endpoint key permissions, and can do its own signing.

Ahead on

  • Reliability, 63 against 55

Watch for

No official MCP server, SDK, llms.txt or OpenAPI file; the registry's Bitstamp servers are third parties proxying public market data

Coinbase MCP server (Coinbase for Agents) C

Best for An agent acting in a person's own Coinbase account, trading spot crypto, US futures and eligible US stocks and paying for market research by x402.

Ahead on

  • Schema & documentation, 65 against 51
  • Agent ergonomics, 66 against 58
  • Security & auth, 70 against 60
  • Payments & pricing, 40 against 20
  • Maintenance & community, 58 against 28
  • Transparency & trust, 62 against 53

Also in its favour

  • A hosted endpoint, with nothing to install
  • Runs on your own machine

Watch for

Only clients Coinbase has allowlisted can connect; other agents need the local CLI and a CDP API key

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 Coinbase MCP server (Coinbase for Agents) +30

Bitstamp API 28

Read as a closed service. The last dated API change is 28 August 2026, 67 days before the check (20). Only one dated entry in the last 90 days, after 1 July and 12 June (0). No public repository or issue tracker, support pages did not load and support.bitstamp.net did not resolve; a changelog exists (8 of 25). No official SDKs and no MCP registry presence of Bitstamp's own (0). No package to assess (0). 20 + 0 + 8 + 0 + 0 = 28.

Coinbase MCP server (Coinbase for Agents) 58

Read as a closed hosted service. The last dated change to the server in the CDP changelog is US stocks on 21 August 2026; the docs added three x402 tools in October (the overview of 2 October still calls them coming soon, the MCP page was modified on 9 October) and the setup guide on 22 October, with no changelog entry. Judgement call (25 of 30). Changelog entries for futures (17 August) and stocks (21 August) both name the MCP server, and the CLI built from the same agent spec shipped six versions from 14 August to 30 September (20). A public changelog, a CDP Discord for integration help and a one-way feedback tool limited to six notes a day, none tested (10 of 25). Not in the official MCP registry; a search for coinbase on 24 October found only third-party servers (0). The CLI has no runtime dependencies but runs a postinstall script and has no public repository or CI (3 of 10).

Payments & pricing Coinbase MCP server (Coinbase for Agents) +20

Bitstamp API 20

No machine payment protocol (0). The fee schedule page loaded empty, the API's fee endpoints need a key, and no rate could be read, so fees are scored as not published (0, unchecked). The API is free, public endpoints need no key and the sandbox needs no money (20). A person must sign up in a browser with identity checks and mint the key (0). 0 + 0 + 20 + 0 = 20.

Coinbase MCP server (Coinbase for Agents) 40

Read the way coinbase-cdp-agentkit was. The server pays x402 as a buyer from the account's USDC balance and its own endpoint isn't paid per call, so the paying-as-a-buyer step (15 of 40). No price for the server itself; trades carry Advanced Trade fees, whose schedule on coinbase.com we couldn't read past a bot check, and x402 prices are advisory and shown only after sign-in (10 of 20). Connecting and reading prices and portfolios cost nothing and need no card, but anything beyond reads needs a verified and funded Coinbase account. Judgement call (15 of 20). A person must sign in to Coinbase in a browser and approve the grant, and only allowlisted clients can register (0).

Schema & documentation Coinbase MCP server (Coinbase for Agents) +14

Bitstamp API 51

No OpenAPI or other machine-readable contract was found on the API page or elsewhere (0). No llms.txt or Markdown docs (0). The single documentation page describes each endpoint's purpose and parameters, with notes such as the 10-second cache on open orders and the Travel Rule fields, but not when to use one endpoint over another (14 of 20). Parameters are typed with enumerations (margin mode CROSS or ISOLATED, margin multiplier 1 to 25, order types) and required fields marked (11 of 15). Signing examples in Python, Java and C++, and error families with numbered codes and explanations (13 of 15). Version v2 in the path and header, a dated changelog from 7 April 2023 to 28 August 2026, and a 410.001 code for deprecated endpoints, with no stated notice period (13 of 15). 0 + 0 + 14 + 11 + 13 + 13 = 51.

Coinbase MCP server (Coinbase for Agents) 65

No public tool manifest. tools/list answered 401 without a token, so the JSON Schema of the 29 tools couldn't be read. The docs say the tool schemas carry field descriptions and enums, and the companion CLI's bundled command spec types every parameter. Judgement call (10 of 25). llms.txt, a Markdown twin of every docs page and a self-contained setup guide written for agents (10). The docs give one line per tool, and the guide has a routing matrix saying which tools to use or avoid for spot, equities and futures, but the tool descriptions as served weren't read (12 of 20). Enums and constraints are described for sessions, order types and sizes, not verified on the server (8 of 15). Order and x402 examples, and two error tables with cause and fix for 401, 403 Missing required scopes, PERMISSION_DENIED, MISSING_FIELDS, INVALID_VALUE, INVALID_FORMAT and x402 failures (13 of 15). Dated Coinbase for Agents entries in the CDP changelog and a versioned guide (0.2.3), but no server version is published and the October changes have no changelog entry (12 of 15).

Security & auth Coinbase MCP server (Coinbase for Agents) +10

Bitstamp API 60

Revocable HMAC-SHA256 keys with per-endpoint permissions, an IP allow-list, single-use nonces, a timestamp window, sub-account scoping and a one-call kill switch for every key; no key expiry found (24 of 30). Permissions are chosen per endpoint and withdrawals can need Travel Rule address verification, but whether a withdrawal address allow-list exists sits in the unread account settings and no confirmation step is documented for API withdrawals (14 of 20). The API returns exchange data, not third-party text (10). No per-key audit log found; the account's transaction history is the record (4 of 15). security.txt names HackerOne's Robinhood programme but expired on 12 July 2026; no certification page was readable (8 of 20). 24 + 14 + 10 + 4 + 8 = 60.

Coinbase MCP server (Coinbase for Agents) 70

Coinbase OAuth with authorisation code and PKCE S256, resource on every request, DCR and CIMD limited to allowlisted clients, ten mcp:* scopes, a consent screen where the person picks portfolios, and revocation under Account > Security > Connections (30). A read-only grant and a funded separate portfolio limit what an agent can touch, and transfers move funds only between the person's portfolios. No per-order size limit or server-side confirmation is documented; the June blog's trade-size limits are still "soon", and the setup guide tells agents to request every scope rather than the least needed (12 of 20). x402 fetch returns third-party data from a curated catalogue only, and the 13 October changelog removes Bazaar resources whose metadata carries prompt-injection risk; no guidance on treating returned data as untrusted was found beyond citing only values the source returns (8 of 15). Orders, transfers and payments appear in the Coinbase account and connections are listed in account settings, but no per-call log for MCP was found (8 of 15). HackerOne bug bounty named in coinbase.com's security.txt, which expired on 1 June 2024; no security.txt on agents.coinbase.com; certifications not read because coinbase.com answered a bot check (12 of 20).

Transparency & trust Coinbase MCP server (Coinbase for Agents) +9

Bitstamp API 53

The editorial half. A closed service whose terms of use loaded empty for our reader, so the licence and clauses are unknown (8 of 30). The privacy policy loaded empty, so retention and data handling are unchecked (0 of 30). A 410.001 code marks deprecated endpoints and the changelog records replacements such as trading-pairs-info by markets, with no notice period stated (8 of 20). Subprocessors and data locations are in the unread privacy policy (0). 8 + 0 + 8 + 0 = 16.

Coinbase MCP server (Coinbase for Agents) 62

The editorial half. A closed hosted service. The docs carry a disclaimer that the person is responsible for every trade an agent makes, but name no terms for agent access, and the Coinbase User Agreement answered a bot check and wasn't read. The CLI is MIT on npm (10 of 30). Per the coinbase-cdp-agentkit check of 1 October 2026, the privacy policy (updated 27 May 2026) names Coinbase, Inc., lists processing countries and ties retention to need without numbers; nothing specific to MCP calls or the feedback tool's screening was found (12 of 30). No deprecation policy or notice period for the server or its tools (0). Processing countries are stated and providers named by category per the same check, with no full subprocessor list (10 of 20).

Reliability Bitstamp API +8

Bitstamp API 63

Read with the hosted lines on the HTTP API v2 at www.bitstamp.net/api/v2/. status.bitstamp.net is a Statuspage site with component history (20). Its feed for 5 August to 3 November 2026 has 17 entries, among them withdrawals failing on 14 networks for about 3 hours on 21 August, database maintenance with login failures and intermittent trading interruptions for about 1 hour 44 minutes on 23 September, a 39-minute halt of all markets on 5 August, and delistings and single-asset suspensions. One major (10). Rate limits with numbers, 400 a second and 10,000 per 10 minutes (15). Limit errors are named (400.002, 400.067, 400.068) but there is no Retry-After or backoff guidance, duplicate client order ids are allowed, and the only retry guidance is to check the order after a 500.016 timeout (8 of 15). No SLA found (0). Generally available (10). 20 + 10 + 15 + 8 + 0 + 10 = 63.

Coinbase MCP server (Coinbase for Agents) 55

Graded with the hosted lines, on the remote server at agents.coinbase.com. status.coinbase.com is a Statuspage site with Advanced Trade, API, US Derivatives and Developer Platform components and 90 days of history, but no component for the agents MCP server, so it shows the trading back end and not the server agents call. Judgement call (10 of 20). Its first history page, 1 August to 24 October 2026, shows minor incidents for derivatives positions and portfolio transfers and one major, a two-minute website slowdown on 14 October, with none for Advanced Trade order entry; 26 to 31 July sits on a second page we didn't read (20). The setup guide says it specifies no numeric request quota for the remote server and that Advanced Trade limits are not the MCP limit (0). It says to honour Retry-After on 429 or back off with jitter, orders take a client_order_id that returns the existing order on retry, and x402 payments take an idempotency_key (15). No SLA found (0). Nothing labels the remote server beta or preview (10).

How the scores have moved

Verdicts

Bitstamp API

Bitstamp documents its v2 API on one static page with numeric rate limits, per-endpoint key permissions, an IP allow-list, a kill switch and a sandbox. There is no official MCP server, duplicate client order ids are allowed, and the fee schedule, terms, privacy policy and country list render by script and could not be read.

Coinbase MCP server (Coinbase for Agents)

Coinbase's remote MCP gives an agent OAuth access to a person's Coinbase account, with ten scopes, per-portfolio grants, revocation from account settings and client order IDs for safe retries. Only allowlisted clients can connect, the tool schemas aren't public, no rate limit is published and no server-side limit on order size is documented.

Before you call either

Bitstamp API

  1. Mint a key with only the endpoint permissions the task needs and an IP allow-list; keep revoke_all_api_keys in reach as a kill switch
  2. Treat client_order_id as a label, not a guard. On a timeout (500.016) fetch the order by client id before resending, because duplicates are accepted
  3. Use a fresh 36-character nonce and a timestamp within 150 seconds of server time on every request, or expect API0004 and API0017
  4. Stay under 400 requests a second and 10,000 per 10 minutes; 400.002 and 400.067 mean back off, and open-orders answers are cached for 10 seconds
  5. Start on sandbox.bitstamp.net with the same paths, and read the fee schedule in a browser before quoting costs, since it is unreadable to a plain fetch

Coinbase MCP server (Coinbase for Agents)

  1. Call coinbase_portfolios_list first and name the portfolio on every order; an order without one falls back to the default portfolio and fails if it isn't granted
  2. Send a fresh client_order_id with each order and reuse it on retry, so a dropped connection doesn't place a second order
  3. Preview with coinbase_orders_preview and confirm with the person before coinbase_orders_create; equity previews may be unavailable
  4. Use ETH-USDC-style pairs when buying with a USDC balance, and base_size in contracts for futures
  5. Agree a spending budget before coinbase_x402_fetch, set max_amount, and keep the idempotency_key for any retry; settled payments can't be reversed
