MCP server that gives AI coding agents deep knowledge of any web component library — properties, events, slots, CSS parts, design tokens, accessibility, health scoring, and more. Works with Claude, Cursor, Windsurf, and any MCP-compatible tool.

<!-- markdownlint-disable MD041 --> <div align="center"> # HELiXiR **Give AI agents full situational awareness of any web component library.** Stop AI hallucinations. Ground every component suggestion in your actual Custom Elements Manifest.

Every attribute, event, slot, and CSS part is sourced directly from your library. - **30+ MCP tools out of the box** — Component discovery, health scoring, design token lookup, TypeScript diagnostics, breaking-change detection, and Storybook story generation — all callable by any MCP-compatible AI agent. - **Works with any web component framework** — Shoelace, Lit, Stencil, FAST, Spectrum, Vaadin, and any library that produces a `custom-elements.json` CEM file. - **Any AI editor, zero lock-in** — Claude Code, Claude Desktop, Cursor, VS Code (Cline/Continue), Zed — one config, any tool. --- ## Quick Start **Under 60 seconds from zero to a comp
