What your AI can do with FluxProof
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “fluxproof_preflight”: Fetch a public URL and return fetchability, size, final URL, title, and content hash without page content or payment.”
“Use “fluxproof_offer”: Return free and paid boundaries and purchase routes without charging.”
“Use “fluxproof_create_monitor”: Create a monitor using a buyer-owned FluxProof API key.”
“Use “fluxproof_check_now”: Run a monitor now and return a source- and hash-bound change receipt.”
How secure is the FluxProof MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how FluxProof holds up.
Security grade D
gate scanned 5 tools on Sep 28, 2026. A few things are worth a look before you connect.
- mediumfluxproof_create_monitor: References secrets or data exfiltration
- mediumfluxproof_check_now: References secrets or data exfiltration
- mediumfluxproof_list_changes: References secrets or data exfiltration
Official endpoint
Operated by FluxProof (workers.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 FluxProof 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 FluxProof
Choose FluxProof in the gate directory. No sign-in needed.
Use it anywhere
FluxProof's tools are live in every AI client you've connected — with rules and logging built in.

Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
fluxproof_preflight — Fetch a public URL and return fetchability, size, final URL, title, and content hash without page content or payment.
fluxproof_offer — Return free and paid boundaries and purchase routes without charging.
fluxproof_create_monitor — Create a monitor using a buyer-owned FluxProof API key.
fluxproof_check_now — Run a monitor now and return a source- and hash-bound change receipt.
fluxproof_list_changes — List recent evidence receipts for a monitor.
Who runs the FluxProof MCP server?
The FluxProof MCP server at a glance
https://fluxproof.neoaethel.workers.dev/mcpQuestions, answered
Is there an official FluxProof MCP server?
Yes — FluxProof operates its own remote MCP server at fluxproof.neoaethel.workers.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 FluxProof to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick FluxProof in the directory. No account or sign-in is needed. From then on, FluxProof's tools are available in every client you've connected to gate.
Do I need to host anything?
No. FluxProof runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the FluxProof 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 FluxProof in minutes. No credit card required.
