What your AI can do with MCP
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “check_vessel”: Screen one vessel by IMO number against OFAC SDN, EU, UN, UK OFSI and OpenSanctions, with an ownership-opacity score and an A–E vetting grad.”
“Use “find_port”: Resolve a port name, country or partial UN/LOCODE to the LOCODEs the routing engine knows. Routes are addressed by LOCODE, so call this befo.”
“Use “screen_vessel”: The authenticated screening record for one vessel: every sanctions match with its source list, programme and confidence class, ownership opa.”
“Use “screen_vessels”: Batch-screen a list of IMO numbers and wait for the results (up to two minutes). Returns one verdict per hull plus the batch status. Needs A.”
How secure is the MCP MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MCP holds up.
Official endpoint
Operated by MCP (arcnautical.com) 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 MCP 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 MCP
Choose MCP in the gate directory. No sign-in needed.
Use it anywhere
MCP's tools are live in every AI client you've connected — with rules and logging built in.
Free to start · No credit card · No hosting needed

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