9 MCP Resilience Patterns That Keep AI Agents Alive in Production (With Code)

Model Context Protocol (MCP) went from "cool demo protocol" to production infrastructure in about six months. But here's the thing — most tutorials show you the happy path. Connect a server, call a tool, done. Production is different. Production means auth failures at 3 AM, context windows exploding, tools timing out, and agents calling the wrong tool because your descriptions were ambiguous. Th...

Should we always use a hybrid encryption protocol to share information?

Whenever we think about sharing information securely, we think about encryption, sharing keys, and the best approach, which is often called "hybrid cryptography." But is it really necessary to expend so many resources on one-way, single messages? For these types of messages, it's not so necessary. Let me give you an example to see why: we need to share a specific piece of data, just one, some coo...

7 AI Agent Orchestration Patterns for Scaling Concurrent Systems (With Production Code)

Every AI agent framework has a "build a research agent in 10 lines" tutorial. Cool. Now try running 50 agents concurrently, handling failures, managing shared state, and keeping costs under control. That's where demos die and engineering begins. These are 7 orchestration patterns that work across frameworks — LangGraph, CrewAI, AutoGen, OpenAI Agents SDK, or your own custom setup. The patterns a...

How to Implement the Saga Pattern for Distributed Transactions in Node.js (2026 Guide)

The hardest problem in distributed systems isn't handling failure — it's handling partial failure. When your order service successfully charges a card but the inventory service crashes before reserving stock, you have a real problem that a single database ROLLBACK can't solve. The Saga pattern is the industry-standard solution for distributed transactions across microservices. In 2026, with most ...

MCP Credential Lifecycle: What Happens When Your Tokens Expire in Production

Most MCP server operators discover their token management strategy the hard way: at 2am, when an agent's tool calls start failing with auth errors and the server logs show nothing useful about why. Credential lifecycle isn't glamorous. It's not something you add to a README. But it's the operational difference between a server that's reliable and one that fails silently whenever a token quietly e...

Junior devs who learned to code with AI assistants are mass entering the job market. How is your team handling it?

We hired two junior devs in the last quarter. Both passed the interview fine. Both can produce working code reasonably fast. But something is off in a way I have not seen before. When something breaks, they do not debug it. They paste the error into ChatGPT and apply whatever it suggests. If that does not work, they paste the new error. I watched one of them go through four rounds of this before I...
