Originally published in French on Medium . An agent works on the developer's laptop, then can't reach its API once deployed at the client. No clear exception, no useful trace: the call just never gets through. In a large company, the first suspect is usually the same: the proxy. That's what…

Telegram bots that receive updates via webhook need to be both secure and idempotent. A lead‑generation Mini App, for example, sends a JSON payload with the user’s contact details to your Laravel endpoint. If you accept the request blindly, an attacker can replay the same update or forge a request…
Most people meet the Model Context Protocol (MCP) through a client like Claude Desktop, where a config file quietly wires up servers and you never see the handshake. But the protocol is just a client and a server talking over a transport, and the official TypeScript SDK gives you every piece you…
The standard way to let an Electron renderer do something privileged is a preload script: you expose a named function over contextBridge , the renderer calls it, ipcMain handles it, and every capability the UI needs becomes a channel you designed, named and now maintain. Notifio does not have one.…
