Security check

How secure is the cnpj.ia.br MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how cnpj.ia.br holds up.

✓ Verified directory servercnpj.ia.br · ia.br

Official endpoint

Operated by cnpj.ia.br (ia.br) 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 cnpj.ia.br adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official cnpj.ia.br MCP server?

Yes — cnpj.ia.br operates its own remote MCP server at mcp.cnpj.ia.br. 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 cnpj.ia.br to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick cnpj.ia.br in the directory. No account or sign-in is needed. From then on, cnpj.ia.br's tools are available in every client you've connected to gate.

Do I need to host anything?

No. cnpj.ia.br runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the cnpj.ia.br 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.
