Added: Kiro CLI leverages the Kiro Auto agent to deliver the best results at the best price, in your terminal, and takes you from natural language, to code, to deployment. Kiro CLI supports different agent modes, MCPs, Kiro steering files, and custom agents, allowing you to mold the CLI to meet your needs.
This release expands MCP capabilities with remote server support and one-click installation, introduces global steering rules and project-specific agent configuration, and refines agent workflows with improved hook execution, command trust, and targeted file context.
Remote MCP Support
Connect to MCP servers hosted anywhere on the internet via Streamable HTTP, accessing cloud services and APIs without local installation.
Global Steering Rules
Define global steering rules that apply across all your workspaces.
AGENTS.md Support
Support for the AGENTS.md standard to define guidelines, coding standards and architectural patterns. Add an AGENTS.md file to the global steering file location (~/.kiro/steering/), or to the root folder of your workspace, and they will get picked up by Kiro automatically.
One-Click MCP Installation
Simplified MCP server setup with automatic installation—get started with MCP tools faster than ever. View servers →
Environment Variable Expansion in MCP
Use environment variables in your MCP server configurations for flexible, environment-specific setups.
Targeted File Context in specs
Loading image...
Reference specific line ranges when adding files to context (e.g., #[[file:src/utils/helper.ts:10-25]]), giving you precise control over what the agent sees and enabling more focused implementations.
This release introduces dev server support with background processes, spec context provider and MVP task workflows, enhanced MCP controls, and per prompt usage tracking with notifications.
Spec MVP Tasks UX
Loading image...
Choose your development pace during spec creation. When the agent generates tasks, select "Keep optional tasks (faster MVP)" to mark tests and documentation as optional (✱), or "Make all tasks required" for comprehensive coverage from the start. Optional tasks remain visible throughout the workflow, letting you focus on core features first
Spec Context in Chat
Use #spec in chat to reference your spec files directly. The agent now understands your spec context, providing more accurate responses during development
Dev server support
Long-running commands like npm run dev, build watchers, and test runners now start in the background automatically. The agent detects these processes, returns control to you immediately, and continues tracking them—no more blocked terminals
Per prompt credit consumption insights
You can now see how many credits each prompt consumed, right in the chat panel.
Proactive Usage Notifications
