Why the edge:
- Maintenance & community, OKX API +23: 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).); OKX API 81 (Read as a closed service with an open-source kit. Changelog entry of 27 October 2026 and kit v1.5.0 on 28 October (30). Changelog entries on 3, 6, 11, 18, 20 and 26 August, 15, 29 and 30 September and 27 October, and kit releases on 20 and 21 August, 1, 7, 14 and 23 September, 19 and 28 October (20). A public changelog, a Telegram community for the kit and GitHub issues whose replies were not read (10 of 15). python-okx is named as the official SDK and the kit is current; the MCP server is not in the official registry (12 of 15). The kit runs CI on push and pull request across Node 18, 20 and 26 with unit tests and coverage (9 of 10). 30 + 20 + 10 + 12 + 9 = 81.)
- Payments & pricing, Coinbase MCP server (Coinbase for Agents) +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).); OKX API 20 (No machine payment protocol (0). The fee table loads by script and the fee FAQ defers to the logged-in view, so no rate was read (0 of 20, unchecked). Public market data and demo trading need no funded account or card (20). A person signs up, verifies and mints a key (0). 0 + 0 + 20 + 0 = 20.)
- Agent ergonomics, OKX API +11: Coinbase MCP server (Coinbase for Agents) 66 (Graded on the remote server. 29 tools per the docs, with no toolsets or read-only subset documented (15). `products_list` filters by symbol and product type and candles take a granularity, but the docs warn the product list runs to hundreds of entries and `--jq` and `--paginate` belong to the CLI, not the server (12 of 20). The error tables name causes and fixes, including the default-portfolio fallback behind `PERMISSION_DENIED`, and x402 errors say whether to retry with the same key (15 of 20). Client order IDs and x402 idempotency keys make retries safe. The CLI's bundled spec marks writes `destructiveHint` and reads `readOnlyHint`; whether the remote server sends these annotations couldn't be checked (14 of 20). Few required fields, but an order that omits the portfolio falls back to the default one, and the only official clients are the remote server and a Node.js CLI (10 of 15).); OKX API 77 (limit parameters on books, candles and history, and in the kit --modules and --read-only narrow 170 tools to the three default modules; no field selection (17 of 25). after, before and limit cursors on history endpoints (18 of 20). Numeric codes with messages, such as 51020 for an invalid quantity, and the kit returns a structured error block with code, message and endpoint (17 of 20). clOrdId on orders, batch endpoints and a cap of 3 amendments in flight; the kit sets readOnlyHint on query tools but destructiveHint false on order tools and has no idempotency key (13 of 20). python-okx, the CLI and a demo profile, with passphrase and HMAC signing on every private call (12 of 15). 17 + 18 + 17 + 13 + 12 = 77.)
- Reliability, OKX API +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 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).); OKX API 65 (Read with the hosted lines on the V5 REST API. okx.com/status is OKX's own page with issue descriptions, maintenance notices and deposit and withdrawal status, but no component history or feed (10 of 20). It lists no incident between 5 August and 3 November 2026; its newest entry is from March 2024, and whether every incident reaches the page cannot be told, so read as clean with a doubt (20 of 30). Rate limits per endpoint, per User ID and per sub-account with numbers, and WebSocket limits (15). Error 50011 on a limit, a clOrdId on orders and a cap of 3 amendments in flight, but no Retry-After or backoff guidance found (10 of 15). No SLA (0). Generally available (10). 10 + 20 + 15 + 10 + 0 + 10 = 65.)
- Schema & documentation, OKX API +8: 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).); OKX API 73 (No OpenAPI file was found in the V5 docs; the kit's tool definitions are typed TypeScript with annotations, and the organisation has an undescribed ai-builder-openapi-md repository we did not read (12 of 25). okx.com/llms.txt exists and links the API and Agent Trade Kit pages, though the V5 docs have no Markdown twins (5 of 10). Each endpoint states its rate limit, rule, parameters and notes (15 of 20). Enums for ordType, tdMode and instType with required flags (12 of 15). Request and response examples per endpoint and an error code list with messages (14 of 15). A dated changelog with an upcoming-changes section that labels breaking changes and dates sunsets (15). 12 + 5 + 15 + 12 + 14 + 15 = 73.)
