A guide to learning how MCP registries help govern AI agent-to-tool connectivity AI agents are only as capable as the tools they can reach. When an agent needs to query a database, file a support ticket, or pull data from a CRM, it has to find the right tool, authenticate, and invoke it — all at runtime. The Model Context Protocol (MCP) standardizes how agents communicate with these tools. But MCP alone does not answer a fundamental question: how does the agent know which tools exist?

Push notifications are one of the most powerful retention tools in mobile. iOS opt-in rates average 40–45%, and apps that use push effectively can triple their long-term retention. However poorly timed, poorly crafted alerts can drain our open rates, leading to opt-outs and disengagement. When designing iOS push notifications, we need to think about engagement and retention, not just impressions.

A strategic framework for using AI-powered quality engineering to accelerate delivery without sacrificing regulatory requirements.

There is a specific kind of dread that comes with finding a critical bug in a production React Native app. The fix is usually straightforward: a broken API call, a logic error, a UI state that did not account for an edge case. You can see exactly what went wrong and exactly how to correct it. The code change might take an hour. What takes days is everything that comes after. App Store review. Google Play review. Waiting. Watching your crash reports climb.

Your data engineers have spent months getting your metric definitions right: revenue recognized the way finance approved it, churn calculated the way your exec team aligned on it, and pipeline logic that your rev ops team actually agrees on. And then a new tool arrives, and someone has to do it all again.

Playwright test agents are LLM-driven execution loops that wrap Playwright's browser automation in a goal-oriented reasoning layer. Instead of executing pre-written scripts, an agent receives high-level intent ("complete checkout and verify the success modal"), inspects the page's accessibility tree, and chooses which Playwright tool to invoke next. The Model Context Protocol (MCP) is the standardized bridge that exposes Playwright capabilities to the LLM and returns structured page context back.
