Svelte 5 Code Writer

CLI Tools

You have access to @sveltejs/mcp CLI for Svelte-specific assistance. Use these commands via npx:

List Documentation Sections

npx @sveltejs/mcp list-sections

Lists all available Svelte 5 and SvelteKit documentation sections with titles and paths.

Get Documentation

npx @sveltejs/mcp get-documentation "<section1>,<section2>,..."

Retrieves full documentation for specified sections. Use after list-sections to fetch relevant docs.

Example:

npx @sveltejs/mcp get-documentation "$state,$derived,$effect"

Svelte Autofixer

npx @sveltejs/mcp svelte-autofixer "<code_or_path>" [options]

Analyzes Svelte code and suggests fixes for common issues.

Options:

• --async - Enable async Svelte mode (default: false)
• --svelte-version - Target version: 4 or 5 (default: 5)

Examples:

# Analyze inline code (escape $ as \$)
npx @sveltejs/mcp svelte-autofixer '<script>let count = \$state(0);</script>'

# Analyze a file
npx @sveltejs/mcp svelte-autofixer ./src/lib/Component.svelte

# Target Svelte 4
npx @sveltejs/mcp svelte-autofixer ./Component.svelte --svelte-version 4

Important: When passing code with runes ($state, $derived, etc.) via the terminal, escape the $ character as \$ to prevent shell variable substitution.

Workflow

1. Uncertain about syntax? Run list-sections then get-documentation for relevant topics
2. Reviewing/debugging? Run svelte-autofixer on the code to detect issues
3. Always validate - Run svelte-autofixer before finalizing any Svelte component
