Security check

How secure is the Workday Calendar MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Workday Calendar holds up.

✓ Verified directory serverWorkday Calendar · workers.dev

Official endpoint

Operated by Workday Calendar (workers.dev) 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 Workday Calendar adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official Workday Calendar MCP server?

Yes — Workday Calendar operates its own remote MCP server at workday-calendar.regnotes.workers.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect Workday Calendar to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick Workday Calendar in the directory. No account or sign-in is needed. From then on, Workday Calendar's tools are available in every client you've connected to gate.

Do I need to host anything?

No. Workday Calendar runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the Workday Calendar MCP server safe to connect?

It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
