MCP Servers Explained: What Model Context Protocol Does

Mon, 13 Apr 2026 10:00:00 +0200

If you have heard “MCP” thrown around in the last year without getting a clear answer on what it is, here is the explainer that stays grounded in what it actually does, not what the marketing decks claim.

I run an MCP server in production. It exposes my task manager to every LLM client I use, daily, as a systemd service on a Debian VPS. That constant use is where this explainer comes from. No conference slides, no speculation about where the protocol is heading in five years. Just what MCP is, what it replaces, and when you should bother writing one.

Claude API Pricing Tiers and Cost Optimization Playbook (2026)

If your Claude API bill jumped this quarter, the fix is almost never “switch providers.” It is usually four or five tactical changes stacked on the same stack you already run.

This is the playbook I apply when I audit a Claude-powered system. It covers the claude api pricing tiers, the rate limits behind them, and ten cost optimizations ordered by actual ROI. The first two levers typically cut 60 to 80 percent off a naive implementation. The rest add up to another 10 to 20 percent.

Build MCP Server TypeScript: Complete Tutorial with Claude

Mon, 30 Mar 2026 11:00:00 +0100

Most teams do not need a custom MCP server. If you have one LLM app, one integration, and one codebase, calling the vendor API directly is faster to ship and easier to debug. The moment you have two Claude surfaces (Claude Desktop plus Claude Code, or Claude Code plus Cursor) hitting the same internal system, you stop duplicating tool code. That is when you build MCP server TypeScript projects worth maintaining.
