Why the edge:
- Security & auth, MEXC API +10: 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.); 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.)
