What your AI can do with Mantis
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “route_market”: Find the best prediction market for a natural-language question or trading intent. Returns the best cross-venue match, current probability,.”
“Use “get_arbitrage”: Find live cross-venue arbitrage opportunities — markets where the same event trades at different prices on Polymarket vs Kalshi vs other ven.”
“Use “execute_url”: Get a deep link URL to place a trade on the best venue for a given market. The URL has a referral code embedded so the platform earns commis.”
“Use “get_quote”: Get the live probability, liquidity, and volume for a prediction market across all venues. Can also return venue order book depth and size-a.”
How secure is the Mantis MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Mantis holds up.
Official endpoint
Operated by Mantis (mantiss.store) 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 Mantis 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 Mantis
Choose Mantis in the gate directory. No sign-in needed.

Mantis's tools are live in every AI client you've connected — with rules and logging built in.

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