V3.5.3 - ExChek Enterprise Plugin
Sign in instead of pasting keys. The ExChek API now has an OAuth-authenticated MCP endpoint (https://api.exchek.us/mcp/pro) backed by the new account portal at app.exchek.us (credits, top-ups, key rotation, connected apps, render history).
exchek-classifycredential resolution now prefers the OAuth connector on claude.ai/Claude Desktop (add/mcp/pro→ sign-in window → consent — no key handling), then theenterprise_api_keyplugin setting, thenEXCHEK_API_KEY, then a pasted key (never on claude.ai/Desktop).- Purchase/management links point at https://app.exchek.us instead of the bare checkout URL.
- ENTERPRISE.md documents both MCP auth modes.
