How secure is the U.CASH Pay MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how U.CASH Pay holds up.
Security grade B
gate scanned 14 tools on Oct 6, 2026. A few things are worth a look before you connect.
- mediumuxc_discover_servers: References secrets or data exfiltration
Official endpoint
Operated by U.CASH Pay (u.cash) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If U.CASH Pay adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

https://mcp.u.cash/Questions, answered
Is there an official U.CASH Pay MCP server?
Yes — U.CASH Pay operates its own remote MCP server at mcp.u.cash. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
