## Which one, for what

### Coinbase MCP server (Coinbase for Agents) (C)

Good 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:
- Reliability, 55 against 45
- Schema & documentation, 65 against 60
- Security & auth, 70 against 55
- Payments & pricing, 40 against 35
- Transparency & trust, 62 against 54

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

### KuCoin (D)

Good for: An agent trading spot, margin and futures in a person's KuCoin account outside the restricted list, with no sandbox and no MCP server, so through the SDK or raw REST.

Ahead on:
- Maintenance & community, 73 against 53

Watch for: No official MCP server; the registry's `kucoin` entry is a third party's keyless market-data package


## Why the edge

### Maintenance & community: KuCoin +20

- Coinbase MCP server (Coinbase for Agents) (53): 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), and the sitemap dates the MCP page and the setup guide (still version 0.2.3) to 2 November 2026, with no changelog entry. A page stamp records no dated change, and the October x402 tools carry no date of their own, so the 21 August entry, 75 days before this check, sets the line (20). 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 4 November found only third-party servers (codespar, junct-bot, mrfentmen, pipeworx-io) (0). The CLI has no runtime dependencies but runs a postinstall script and has no public repository or CI (3 of 10). 20+20+10+0+3 = 53.
- KuCoin (73): Read as a closed hosted service. The changelog's newest past entry is 2 November 2026 and the universal SDK was pushed 15 September (30). Nine dated changelog entries since 5 August 2026 (20). A Telegram API group (t.me/KuCoin_API) and api@kucoin.com for limit requests, no public issue tracker for the API; the SDK repository's issues were not checked (10 of 25). Official SDKs current in five languages, no MCP registry presence (13 of 15). No package health signal checked (0 of 10). 73.

### Security & auth: Coinbase MCP server (Coinbase for Agents) +15

- 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 all scopes needed for the intended capabilities, not to stop at read-only because setup checks with a portfolio list, while honouring an explicit read-only request (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).
- KuCoin (55): API key with a user-set passphrase, HMAC-SHA256 signing, nine permission groups, IP allow-lists required for Withdrawal and FlexTransfers, trading keys without an IP disabled after 30 days of inactivity, revocation on the management page; no OAuth and no expiry on General keys (24 of 30). A General-only key is a true read-only mode and withdrawals are a separate permission; no confirmation step for writes beyond the key scope (12 of 20). Tools return the exchange's own data (10). The API key info endpoint shows permissions and IP lists; no per-call audit log was found (5 of 15). No security.txt, no disclosure policy or bounty on a page we could read, a whistleblower notice on the legal page (4 of 20). 55.

### Reliability: Coinbase MCP server (Coinbase for Agents) +10

- 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 history page read on 24 October covers 1 August to 24 October 2026, and its history feed, read on 4 November, 16 October to 4 November. Together they cover the window from 6 August. They show minor incidents for derivatives positions and portfolio transfers (21 October, some customers), a 64-minute BRL conversion fault for some users on 26 October and a two-minute website slowdown on 14 October, with none for Advanced Trade order entry (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). 10+20+0+15+0+10 = 55.
- KuCoin (45): Graded with the hosted lines on the API at api.kucoin.com. No status page found (status.kucoin.com does not resolve, the docs link none), so 0 for the page and 5 for no readable history. Rate limits are published per VIP level with per-endpoint weights and IP limits for public endpoints (15). Every response carries gw-ratelimit-limit, gw-ratelimit-remaining and gw-ratelimit-reset, 429000 is documented with a wait rule, and orders take a clientOid the docs recommend as a UUID (15). No SLA (0). The UTA V2 API is the production surface (10). 45.

### Transparency & trust: Coinbase MCP server (Coinbase for Agents) +8

- 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).
- KuCoin (54): The editorial half. A closed hosted service with terms that are clear on use, liability and law but name no company (12 of 30). The privacy policy gives retention periods by purpose and provider (2 years after closure, 14 months for Firebase, 3 years for Jumio, 5 years for Sumsub) and names 41 services, with no data centre locations (22 of 30). Endpoints are removed and fields deprecated in dated changelog entries with no notice period or policy (8 of 20). Third parties named by service, locations not stated beyond transfers around the globe (10 of 20). 52.

### Schema & documentation: Coinbase MCP server (Coinbase for Agents) +5

- Coinbase MCP server (Coinbase for Agents) (65): No public tool manifest. The docs tell clients to use the names their own connection's `tools/list` returns, so the JSON Schema of the 29 tools is served only to a signed-in connection and wasn't 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).
- KuCoin (60): No OpenAPI or other machine-readable contract was found; the docs link a Postman workspace and the universal SDK is generated from an internal spec (8 of 25). No llms.txt; the skills hub ships Markdown SKILL.md files with endpoint tables for seven product areas, read-only (6 of 10). One docs page per endpoint with a description, permission and weight, but no when-to-use guidance (12 of 20). Typed parameter tables with enums for type and side and required flags (11 of 15). Request and response examples per endpoint and a unified six-digit error code scheme introduced with V2 (10 of 15). Dated changelog with V1 to V2 versioning (13 of 15). 60.

### Payments & pricing: Coinbase MCP server (Coinbase for Agents) +5

- 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).
- KuCoin (35): No machine payment protocol (0). The spot base fee is stated in support articles without login, the futures base rate and the full tier table sit in images or behind script (15 of 20). Market data needs no key, no card is asked for at sign-up (20). A person registers, verifies identity and mints the key in a browser (0). 35.

## Verdicts

**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.

**KuCoin.** KuCoin publishes pooled rate limits with remaining and reset headers, scoped keys where withdrawals and transfers need an IP allow-list, an official SDK in five languages and read-only agent skills. It runs no MCP server, has no sandbox, status page or OpenAPI file, and its terms name no legal entity.

## Before you call either

### 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

### KuCoin

1. Mint a key with General only for research; add Spot or Futures only with an IP allow-list, since unbound trading keys are disabled after 30 days of inactivity
2. Send a UUID clientOid on every order and keep it for the retry, and read the order back by clientOid before placing again
3. Budget requests by weight against gw-ratelimit-remaining and sleep for gw-ratelimit-reset milliseconds on 429000; sub-accounts share the pool
4. There is no sandbox, so rehearse with the smallest order size on a dedicated sub-account
5. Use the UTA V2 endpoints and hosts; the Classic API loses endpoints without notice, as the margin credit endpoints did on 21 October 2026
