I Ran My Own Favicon Checker Against 10 Sites. All 10 Failed.

I maintain a small collection of single-purpose web tools. Last month I built a favicon checker: you type a URL, it reads the icon declarations in the HTML head, probes every referenced file, and also hits /favicon.ico directly, because plenty of software still requests that path without ever readin

Why everyone loves Proxmox at home, but many pros do not even know about it?

Ever since I have been tinkering with Proxmox, I noticed the huge amount of support it seems to get on Reddit subs and generally in the "homelab" cohort. But when you mention this to any sysadmin, they look at you with a smirk like you had just told them about your Lego side project or even outright

Building an SPL Token: Creating the Mint

Now that we have a mental model of how Solana works, it’s time to actually use it. We’ve talked about accounts holding state, programs containing the logic, instructions telling those programs what to do, and transactions bringing those instructions together. Creating an SPL Token Mint is a good pl

When an AI Agent Makes a Mistake in Production, Which Layer Should Stop It?

A familiar production failure looks like this: an AI support agent reads a ticket, decides the customer deserves compensation, calls the refund tool, and refunds the full annual subscription instead of the $12 add-on. The model did not crash. The API did not throw an exception. The tool worked exact

From API to AI Agent: Turning a Laravel Backend Into a Tool-Using System

Your team decides to add an AI agent to your Laravel application. The initial plan seems straightforward: give the LLM access to your existing REST API, let it figure out the endpoints, and watch it automate customer support. Then production happens. The agent calls GET /api/users and pulls 14,0

Why Most AI Agents Fail Long Before the Model Does

The agent did not fail because the model was stupid. It failed because a CRM tool returned a 502, the agent retried, created two support tickets, read a stale knowledge-base article, filled the context window with stack traces, and then told the customer everything was fine. When teams see this, th

Seven ways a remote MCP server gets authorization wrong

Remote MCP servers are shipping fast, and a lot of them are generated straight out of an OpenAPI spec or a no-code builder. That is fine for a demo. It stops being fine the moment a real agent, holding real credentials, is allowed to call real tools against real customer data. These are the seven f

The confused deputy, or why "just forward the token" breaks your MCP server

Here is a failure that does not look like a bug in code review, passes every test you wrote, and quietly hands an attacker your privileges. It is called the confused deputy, and it is the reason "just forward the token" is one of the most expensive shortcuts you can take in an MCP server.

OAuth 2.1 for MCP servers, done properly

Authorization is formally optional in MCP. That wording misleads people. It means you may run an unprotected server; it does not mean you get to half-implement a protected one. The moment you do protect an HTTP transport, the spec fills up with MUSTs, and most teams meet maybe half of them: pull in
