How secure is the papertax MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how papertax holds up.
Official endpoint
Operated by papertax (papertax.xyz) 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 papertax 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 papertax
Choose papertax in the gate directory. No sign-in needed.

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

The papertax MCP server at a glance
https://papertax.xyz/mcpQuestions, answered
Is there an official papertax MCP server?

Add gate's gateway URL to your AI client once, then pick papertax in the directory. No account or sign-in is needed. From then on, papertax's tools are available in every client you've connected to gate.
Do I need to host anything?
No. papertax runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the papertax 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.
