Spreadsheets, dashboards, scripts, and AI assistants all need real data. HalAxe allows them to connect to your systems without ever exposing your login details.
No sign-up · Nothing stored online
When every tool stores its own token, every tool is a risk. A compromised script, a shared spreadsheet, a chatbot with your API key. Any one of them can expose access to your systems.
Your login lives in HalAxe, on your machine. Spreadsheets, dashboards, scripts, and AI assistants all send their requests through it and get data back. None of them ever holds a credential.
Give it a name, paste in the address, and sign in silently or through the same window you'd normally see.
Copy the small address HalAxe gives you into whatever you're using: a spreadsheet, a script, a dashboard, or an assistant's settings.
Ask, run, or refresh like normal. Watch what comes back. And if you ever want a tool cut off, one click shuts the door.
Your login goes into HalAxe once, on your own machine. Every request, whether it's a spreadsheet, a script, or an AI assistant, refers to it by name only, and HalAxe fills in the real value as it leaves. There is nothing for any of them to remember, leak, or reuse.
There's no HalAxe account and no HalAxe cloud. Your logins live encrypted on your computer, and requests go straight from your machine to your system.
Every connection runs through HalAxe, so stopping one is as simple as switching it off there, or quitting HalAxe from the tray, and whatever was using it, including an AI assistant, is locked out immediately, with no key to revoke and nothing to clean up.
HalAxe sits quietly on your computer, handing out one small local address that anything running on the same machine can use as soon as it's ready.
For the technically minded: HalAxe is a local proxy and MCP server, reachable from other software on the same computer. It handles OAuth 2.0 and OpenID Connect sign-in, including authorisation code, PKCE, client credentials and static API keys, refreshes tokens in the background, and resolves credential placeholders server-side so no connected tool ever receives a secret. If none of that means anything to you, it doesn't need to, because there's a simple header option too.
Everything above already applies. HalAxe doesn't care whether the question comes from a spreadsheet formula or from an assistant you're chatting with. If you use one, it can ask these directly.
"How much stock do we have right now?"
The assistant asks HalAxe for today's numbers and comes back with the count, the value, and where it's sitting.
"Where did most of our money go last quarter?"
It adds up the real numbers and names the biggest suppliers by amount, in order.
"Email that to me with a chart."
It builds the summary, draws the chart, and sends it through your own email setup.
To be clear about the parts: the assistant does the thinking. HalAxe gets it through the login, and keeps your password out of its hands either way. Both matter, and they're different jobs.
One small file, no sign-up. Add your first system, point a tool at it, and see whether it saves you the afternoon this usually takes. Connect an assistant too, if you use one.
