What your AI can do with Upgrade Agent
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “check_upgrade_eligibility”: Look up a booking's upgrade eligibility from a PNR + last name + airline. USE THIS WHENEVER the traveler has typed their booking reference a.”
“Use “start_eligibility_check”: Check whether a specific booking is eligible for an upgrade. THIS IS HOW YOU CHECK A BOOKING. You do NOT need access to any reservation syst.”
“Use “mint_eligibility_session”: Internal helper for the inline eligibility form: creates a secure session and returns its id. No UI; agents should use start_eligibility_che.”
“Use “get_eligibility_result”: Read the result of a secure eligibility check started with start_eligibility_check. Pass the sessionId returned by that tool. Returns the li.”
How secure is the Upgrade Agent MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Upgrade Agent holds up.
Official endpoint
Operated by Upgrade Agent (upgradeagent.ai) 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 Upgrade Agent adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The Upgrade Agent MCP server at a glance
https://www.upgradeagent.ai/api/mcpQuestions, answered
Is there an official Upgrade Agent MCP server?
Yes — Upgrade Agent operates its own remote MCP server at www.upgradeagent.ai. 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 Upgrade Agent to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Upgrade Agent in the directory. No account or sign-in is needed. From then on, Upgrade Agent's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Upgrade Agent runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Upgrade Agent 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.
Is it free?
Yes — you can get started with gate for free and connect Upgrade Agent in minutes. No credit card required.
