Overview

The Starwind UI Astro Components MCP Server is a small service that exposes machine-readable metadata, commands, and documentation for the Starwind UI component collection so that large language models (LLMs) and other automated systems can discover, inspect, and use those components programmatically. It implements the Model Context Protocol (MCP) pattern: it provides a manifest of available tools/resources and endpoints that let an LLM query component lists, read prop schemas, retrieve examples, and request generated code snippets.

This server is useful when you want to integrate Starwind UI into automated developer workflows — for example, an assistant that can recommend components, generate usage examples in Astro, or produce migration steps. By packaging component metadata and useful tooling behind a stable MCP interface, the server helps LLMs take precise actions and produce safer, more accurate developer output.

Features

  • Exposes a machine-readable manifest describing tools and resources for Starwind UI components
  • Serves component metadata: names, props, default values, and usage examples
  • Provides example Astro snippets and pattern templates for each component
  • Command endpoints (tools) for generating code, searching components, and exporting docs
  • Designed to be run locally or deployed to a cloud service for LLM integrations
  • Simple configuration via environment variables and file paths

Installation / Configuration

Requirements:

  • Node.js 18+ (or compatible)
  • Git
  • pnpm (recommended) or npm/yarn

Clone and install dependencies:

git clone https://github.com/Boston343/starwind-ui-mcp.git
cd starwind-ui-mcp
pnpm install
# or: npm install

Create a configuration file (.env) or set environment variables. Typical variables:

  • PORT — HTTP port to run the server on (default shown)
  • COMPONENTS_DIR — path to the cataloged Starwind UI components
  • LOG_LEVEL — verbosity (info/debug)

Example .env:

PORT=3333
COMPONENTS_DIR=./components
LOG_LEVEL=info

Run in development:

pnpm dev
# or
node src/server.js

Build and run for production:

pnpm build
pnpm start

Note: If your project uses a different package manager, adapt the commands accordingly. Ensure the COMPONENTS_DIR points to the folder containing component metadata, examples, or the source repo you want the MCP server to index.

Available Resources

The server provides a set of resources typically exposed through an MCP-style manifest and a small set of REST endpoints or RPCs. Example resources you will find in the repo or served by the running instance:

ResourcePurpose
MCP manifestMachine-readable list of tools and metadata the server exposes
Component catalogJSON/YAML metadata for each component: props, defaults, types
Examples collectionSmall Astro snippets showing typical usage per component
Generation toolsEndpoints to request tailored component snippets or prop tables
Documentation filesHuman-readable docs and links for each component

Example: fetch manifest (replace host/port if different):

curl http://localhost:3333/mcp/manifest

Typical manifest contains tool definitions, entrypoints, and resource URIs so an LLM can decide which tool to call.

Use Cases

  1. Assistant-driven component discovery

    • Scenario: An LLM-based code assistant receives “I need a responsive button with an icon.”
    • Flow: The assistant queries the MCP manifest, uses a search tool to find matching components in the catalog, reads the button prop schema, and returns a tailored Astro snippet with props set for accessibility and responsiveness.

  2. Automated code generation for pages

    • Scenario: Generate a full page layout using Starwind UI primitives.
    • Flow: Call the MCP server’s “generate-snippet” tool, supplying a high-level intent (e.g., “landing page hero with CTA and feature cards”). The server returns ready-to-use Astro component markup with suggested props and example CSS classes.

  3. Documentation and migration automation

    • Scenario: You need a props table for the Button component for the docs site.
    • Flow: The assistant requests the component metadata from the MCP server, then formats the prop list into a Markdown table suitable for your docs site or automated changelog.

  4. CI tooling and validation

    • Scenario: Validate that component prop usage in PRs conforms to current prop types.
    • Flow: Build a small script that queries the MCP server for prop schemas and runs quick checks on changed files in CI to flag breaking prop changes.

Tips for Developers

  • Keep the components catalog up to date: regenerate metadata after component changes so LLMs get accurate info.
  • Limit the surface area of tools exposed in production to reduce unintended actions by an LLM.
  • Use example-driven generation: bundle multiple short examples per component to improve quality of generated snippets.
  • Secure the server when exposing it publicly — use authentication and restrict which tools resources an external LLM can call.
  • GitHub repository: https://github.com/Boston343/starwind-ui-mcp/
  • Typical MCP design pattern: manifest + tool invocation (see your server’s manifest endpoint for specifics)
  • If you plan to integrate with hosted LLMs, map MCP tools to your model’s function-calling or tool-use features for safer automation.
