How secure is the Code402 MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Code402 holds up.
Official endpoint
Operated by Code402 (code402.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 Code402 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 Code402
Choose Code402 in the gate directory. No sign-in needed.
Use it anywhere
Code402's tools are live in every AI client you've connected — with rules and logging built in.

Who runs the Code402 MCP server?
The Code402 MCP server at a glance
https://mcp.code402.dev/mcpQuestions, answered
Is there an official Code402 MCP server?
Yes — Code402 operates its own remote MCP server at mcp.code402.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 Code402 to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Code402 in the directory. No account or sign-in is needed. From then on, Code402's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Code402 runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Code402 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 Code402 in minutes. No credit card required.
