What your AI can do with Zeno
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “find_operations”: Search EVERY operation this server offers, including the ones not in your tool list. The tool list you can see holds only the common operat.”
“Use “describe_operations”: Get the full argument schema for operations found via ``find_operations``. Returns each operation's description and JSON-Schema arguments —.”
“Use “call_operation”: Run any operation by name — the ones in your tool list and the unlisted ones alike. ``name`` is an operation name from ``find_operations``;.”
“Use “request_api_key”: Ask the user to hand this session a Zeno API key. **Use this first** — every current Zeno user already has an account. `email` is the addre.”
How secure is the Zeno MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Zeno holds up.
Official endpoint
Operated by Zeno (zeno-works.ch) 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 Zeno adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Zeno
Choose Zeno in the gate directory. No sign-in needed.
Use it anywhere
Zeno's tools are live in every AI client you've connected — with rules and logging built in.

The actual tools Zeno exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
find_operations — Search EVERY operation this server offers, including the ones not in your tool list. The tool list you can see holds only the common operat
describe_operations — Get the full argument schema for operations found via ``find_operations``. Returns each operation's description and JSON-Schema arguments —
call_operation — Run any operation by name — the ones in your tool list and the unlisted ones alike. ``name`` is an operation name from ``find_operations``;
request_api_key — Ask the user to hand this session a Zeno API key. **Use this first** — every current Zeno user already has an account. `email` is the addre
start_signup — Create a Zeno account for somebody who does not have one yet. Use `request_api_key` first if they might already have an account — this tool
collect_api_key — Collect the key once the user has approved. `status` is one of: - `pending` — nobody has approved yet, or (with `throttled: true`) we were

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