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.\n- MEXC API (65): Granular permissions (account read, trade, withdraw, transfer), per-pair restriction, up to 10 linked IPs, 90-day expiry without an IP, renewal and revocation in the account, 30 keys per account (26 of 30). A read-only MCP mode that hides write tools, a confirmation step before orders and transfers in the CLI and MCP, and --yes that agents are told not to add; nothing server-side confirms an API order (17 of 20). The API returns exchange data, and the CLI security page warns that agents may be led by web pages or files into unwanted actions (12 of 15). CLI confirmations are logged and reported to MEXC with no operator access described; an apiKeyInfo endpoint shows key settings (6 of 15). No security.txt, disclosure policy or bug bounty found; a proof-of-reserves page exists (4 of 20). 26 + 17 + 12 + 6 + 4 = 65.\n\n## Score by category\n\n| Category | Weight | KuCoin | MEXC API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 45 | 43 | KuCoin +2 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 60 | 64 | MEXC API +4 |\n| Agent ergonomics | 13% (16.2 this run) | 62 | 64 | MEXC API +2 |\n| Security \u0026 auth | 14% (17.5 this run) | 55 | 65 | MEXC API +10 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 35 | 31 | KuCoin +4 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 73 | 75 | MEXC API +2 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 54 | 58 | MEXC API +4 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **53.9 · D** | **56.3 · C** | |\n\n## Facts side by side\n\n| Fact | KuCoin | MEXC API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | KuCoin | MEXC (Comoros) Ltd |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | stdio |\n| Auth | API key | API key |\n| Pricing | Pay per use | Pay per use |\n| x402 | no | no |\n| Tools exposed | none | 299 |\n| Read-only variant documented | yes | yes |\n| llms.txt | no | yes |\n| Last release | 2026-11-02 | 2026-10-23 |\n| Terms last updated | no date given | 2026-10-13 |\n| Privacy policy last updated | no date given | 2026-06-01 |\n| Customer content may train models | not found in the text | not found in the text |\n| Terms restrict automated access | yes | yes |\n| Terms restrict benchmarking | not found in the text | not found in the text |\n| Terms or service can change without notice | yes | yes |\n| Arbitration or class-action waiver | yes | yes |\n| Popularity | 55 stars | 315 stars |\n\n## Verdicts\n\n**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.\n\n**MEXC API.** MEXC publishes granular key permissions, per-pair key limits, weighted rate limits with Retry-After and a dated changelog, and its official CLI runs a read-only-capable MCP server with confirmation before any fund movement. There is no sandbox or status page, API futures orders pay a higher fee schedule, and the user agreement excludes the US, UK, EU members and others.\n\n## Before you call either\n\n### KuCoin\n\n1. 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\n2. Send a UUID clientOid on every order and keep it for the retry, and read the order back by clientOid before placing again\n3. Budget requests by weight against gw-ratelimit-remaining and sleep for gw-ratelimit-reset milliseconds on 429000; sub-accounts share the pool\n4. There is no sandbox, so rehearse with the smallest order size on a dedicated sub-account\n5. Use the UTA V2 endpoints and hosts; the Classic API loses endpoints without notice, as the margin credit endpoints did on 21 October 2026\n\n### MEXC API\n\n1. Use a key limited to SPOT_ACCOUNT_READ and SPOT_DEAL_WRITE, the pairs you trade and your IP addresses; keys without a linked IP expire after 90 days\n2. Start the MCP server as `mexc mcp spot --read-only` unless the task trades, and never pass `--yes`; orders and transfers wait for the person's confirmation\n3. Call POST /api/v3/order/test before a live order, since there is no sandbox\n4. On 429 or 418 wait for Retry-After; order placement and cancellation share 12 requests a second per UID, and repeated breaches ban the IP for up to 3 days\n5. Treat a 5xx on an order as unknown, not failed, and query the order before retrying; set newClientOrderId so the order can be found\n\n## Questions\n\n### Which is better for AI agents, KuCoin or MEXC API?\n\nMEXC API scores 56.3 (C) on agent readiness against KuCoin's 53.9 (D), and leads in 5 of 7 scored categories.\n\n### Do KuCoin and MEXC API need an API key?\n\nBoth need an API key.\n\n### Can an agent call KuCoin and MEXC API without installing anything?\n\nNo hosted endpoint is listed for KuCoin.
