How to Optimize Your CI/CD Pipeline with AI (CircleCI Chunk Tutorial)

As AI-assisted coding tools increase the amount of code, commits, and builds, optimizing your CI pipeline becomes more important than ever. In this tutorial, we walk through how to use Chunk, CircleCI’s autonomous agent that validates your code at AI speed, to analyze your pipeline history, identify performance bottlenecks, and suggest optimizations to your CI/CD configuration. Chunk leverages critical CI/CD context like build history, test results, and execution data to keep pipelines healthy and moving at AI speed.

MCP vs. CLI for AI-native development

Summary: The CLI vs. MCP question is really a question about where you are in the development loop. CLIs fit the inner loop: fast, local, zero overhead. MCP servers fit the outer loop: external systems, shared infrastructure, structured access. Most teams need both. AI has put a new kind of scrutiny on developer tooling. When a developer works alongside an AI coding assistant, the tools that assistant can reach, and how it reaches them, directly affect the quality and speed of the work.
