The "LSP Moment" for AI Agents: WebStorm ACP - The JetBrains Blog
Blog post from JetBrains
WebStorm has introduced support for the open Agent Client Protocol (ACP), which separates AI agents from the IDE much as the Language Server Protocol separated language tooling from editors, allowing developers to use compatible agents from providers such as Anthropic, OpenAI, Google, GitHub Copilot, and Claude Code without requiring a JetBrains AI subscription. ACP standardizes the exchange of project context and agent actions, supports curated registry agents and privately configured agents, and enables bring-your-own-key deployments across cloud or local model infrastructure. The approach is intended to let developers switch among specialized agents for tasks such as UI implementation, refactoring, debugging, code review, documentation, and commit-message generation while retaining WebStorm’s indexing, navigation, and refactoring capabilities. A highlighted workflow combines a frontend-focused agent with Figma Connect and Chrome DevTools Connect to translate designs into React components, inspect browser errors, apply fixes, and verify results from within the IDE. For organizations, ACP is positioned as a way to control approved providers, maintain data-compliance boundaries, standardize available tools, and deploy custom agents containing internal knowledge and coding standards.
