WP Astro MCP
Add a blazing-fast Astro frontend to any WordPress site -- from a single blog to a network of 12 sites with 6,000+ posts. WordPress stays as your headless CMS. Fully automated via Claude Code.
WP Astro MCP is a Model Context Protocol server that adds a production-ready Astro frontend layer to your WordPress sites. WordPress remains your content engine -- the CMS where editors write, publish, and manage everything. Astro becomes the fast, public-facing delivery layer. The server connects to your WordPress REST API, extracts everything (posts, pages, CPTs, SEO, ACF, menus, media), converts HTML to clean Markdown, scaffolds a complete Astro project, keeps content in sync, and pushes to GitHub -- all through conversational commands in Claude Code.
Why This Exists
Running WordPress as a headless CMS with an Astro frontend gives you the best of both worlds: WordPress's mature content management for editors, and Astro's static performance for visitors. But wiring it all up involves dozens of tedious steps: fetching content via API, resolving shortcodes, building frontmatter, setting up content collections, handling media URLs, generating redirects, deploying, and keeping content in sync as editors publish new posts.
This MCP server handles all of it. Tell Claude to set up your Astro frontend, and it orchestrates 57 specialized tools to get it done -- and keeps your Astro site current with every WordPress content change.

Quick Start
1. Install
git clone https://github.com/vapvarun/wp-astro-mcp.git
cd wp-astro-mcp
npm install
npm run build2. Add to Claude Code
Add to your MCP config (~/.claude.json or project .mcp.json):
{
"mcpServers": {
"wp-astro-mcp": {
"command": "node",
"args": ["/path/to/wp-astro-mcp/dist/index.js"]
}
}
}3. Generate a WordPress Application Password
Go to your WordPress admin -> Users -> Profile -> Application Passwords. Enter a name, click "Add New", and copy the password.
4. Start Building
In Claude Code, just say:
Add my WordPress site example.com with username admin
and app password "xxxx xxxx xxxx xxxx xxxx xxxx"Claude will register the site, auto-detect its capabilities (SEO plugin, ACF, post types, taxonomies), and guide you through setting up the Astro frontend.
Even faster: Use setup_wizard to do the entire flow in one command -- from WordPress site to deployed Astro frontend in 5 minutes.

Every post goes through a 13-step conversion to generate the Astro content layer:
Sanitize -- DOMPurify removes XSS vectors while preserving content
Resolve shortcodes -- Built-in handlers (gallery, video, audio, caption) + custom per-site rules
Process Gutenberg -- Remove block comments (
<!-- wp:paragraph -->), preserve contentNormalize HTML -- Decode entities, remove empty paragraphs, clean inline styles
Convert to Markdown -- Turndown with WordPress-specific rules (captions, galleries, code blocks, embeds)
Rewrite links -- Internal WordPress URLs -> Astro paths using URL map
Rewrite media -- Swap domains for media URLs (e.g.,
example.com->app.example.com)Clean artifacts -- Remove conversion leftovers, fix double-encoded entities
Process embeds -- YouTube/Vimeo iframes -> plain URLs
Handle galleries -- WordPress galleries -> image grids
Fix whitespace -- Ensure proper spacing around headings, lists, code blocks
Validate -- Flag remaining HTML, broken images, content loss
Page builder note: Content built with page builders (Elementor, WPBakery, Divi, etc.) comes through the REST API as deeply nested HTML -- far more markup than actual content. The pipeline extracts text content from this HTML, but complex layouts (multi-column sections, styled cards, animated elements) will lose their visual structure. This tool works best with standard WordPress content (Gutenberg blocks, classic editor). For page-builder-heavy sites, review output with convert_preview and expect some manual cleanup.
Use Cases
Add Astro Frontend to a Personal Blog
You have a WordPress blog with 200 posts and want a faster public-facing frontend while keeping WordPress as your content editor.
1. "Add my site myblog.com with username admin and password xxxx"
2. "Analyze the site"
3. "Set output to C:/projects/myblog-astro with Vercel deployment"
4. "Preview some converted posts"
5. "Scaffold the Astro project and export all content"
6. "Push to GitHub"WordPress stays at app.myblog.com for content management. Astro serves myblog.com.
Add Astro Frontend to a Business Website
A company site with Yoast SEO, ACF custom fields, and 500 posts/pages using the standard editor.
1. "Add site company.com" (auto-detects Yoast, ACF, post types)
2. "Run a content audit" (finds shortcodes, blocks, embeds, complexity)
3. "Configure shortcodes for CF7 forms and custom widgets"
4. "Preview 5 posts to check conversion quality"
5. "Export all content, media URLs pointing to app.company.com"
6. "Generate Netlify redirects and push to GitHub"WordPress moves to app.company.com at go-live. Astro takes the main domain.
Set Up Astro Frontends for Multiple Sites
An agency managing 12 WordPress sites that all need fast Astro frontends.
1. "Add all my sites" (register each with credentials)
2. "List all sites" (see capabilities and content counts)
3. "Analyze buddyxtheme.com" (1,941 posts, RankMath, ACF)
4. "Export buddyxtheme.com with year/month directories"
5. "Now do vapvarun.com" (switch sites seamlessly)Content Sync (The Core Ongoing Workflow)
WordPress is a living CMS -- editors publish new posts, update content, change images, and delete old pages daily. The sync tools keep your Astro frontend current without regenerating everything from scratch. This is the day-to-day operational workflow once your Astro frontend is live.
1. "Sync check myblog.com" (see what changed since last sync)
2. "Sync pull" (fetch and write only the changed content)
3. "Sync full with auto-commit" (check + pull + delete + commit in one command)
4. "Set up daily sync via GitHub Actions" (automate it permanently)Incremental Content Generation
Need to generate the Astro content layer for a subset of content, or resume after interruption.
1. "Export only posts modified after 2024-01-01"
2. "Resume the export" (picks up where it left off)
3. "Validate the export" (check for missing files or failures)Go-Live Domain Swap
At go-live, WordPress moves from example.com to a subdomain (e.g., app.example.com) where it continues as the headless backend. Astro takes over example.com as the public frontend.
1. During development: media URLs point to example.com (no changes needed)
2. At go-live: "Rewrite all media URLs from example.com to app.example.com"
3. "Generate redirects for Vercel"Full Workflow
Here is the complete workflow for adding an Astro frontend to your WordPress site, step by step:
Phase 1: Connect and Discover
site_add -> Register site, auto-detect WP version, SEO plugin,
ACF, WooCommerce, post types, taxonomies
site_analyze -> Count all content, assess site readiness, estimate build time
site_export_config -> Set output directory, media strategy, deploy platformPhase 2: Audit and Prepare
content_audit -> Sample posts, detect shortcodes, blocks, embeds,
galleries, tables, forms -- assess complexity
shortcode_scan -> Find all shortcodes in use across the site
shortcode_configure -> Set handling rules (strip, keep content, map to component)
cache_terms -> Pre-cache all taxonomy terms in SQLite
cache_authors -> Pre-cache all authors in SQLitePhase 3: Preview and Verify
convert_preview -> Convert 3-5 sample posts, review Markdown quality
convert_post -> Convert a specific post to inspect in detail
extract_post -> View raw WordPress data for debuggingPhase 4: Scaffold and Generate Content Layer
scaffold_project -> Create Astro project (config, layouts, pages, collections, RSS)
export_plan -> Pre-flight check: content counts, config validation, time estimate
export_start -> Begin batch content generation (processes first batch, creates SQLite job)
export_resume -> Continue processing (call repeatedly until done)
export_progress -> Check completion percentage and failures
export_retry -> Re-process any failed posts
export_validate -> Verify all output files exist and are validPhase 5: Finalize and Go Live
generate_redirects -> Create redirect rules (Netlify, Vercel, Cloudflare, Apache, Nginx)
media_audit -> Check all media references, find broken URLs
media_rewrite -> Bulk swap media domains for go-live (example.com -> app.example.com)
github_init -> Initialize git repository
github_create_repo -> Create GitHub repo (public or private)
github_commit -> Stage and commit all changes
github_push -> Push to GitHub
github_deploy_config -> Generate Vercel/Netlify/Cloudflare configPhase 6: Ongoing Content Sync (Day-to-Day Operations)
sync_check -> Compare WordPress vs local files -- find new, updated, deleted posts
sync_pull -> Fetch and write only changed content to Astro
sync_delete -> Remove local files for posts deleted/trashed in WordPress
sync_full -> Complete sync in one command: check -> pull -> delete -> optionally commit
sync_status -> Show sync history and error counts
sync_schedule -> Generate automated sync (GitHub Actions, cron, webhooks)
sync_reset -> Clear sync tracking to force a full re-checkPhase 7: wp-astro-bridge Plugin (Optional Power-Up)
Install the companion WordPress plugin for automatic rebuilds and draft preview.
setup_wizard -> Auto-detects if wp-astro-bridge is installed
sync_webhook -> Process individual post webhooks (targeted single-post sync)
sync_schedule -> wordpress-plugin option generates setup instructionsWebhook auto-rebuild: Editor publishes -> plugin fires webhook -> Astro rebuilds in 1-2 min. Draft preview: Editor clicks Preview -> sees draft on real Astro frontend design. Settings: Astro URL, Webhook URL, Secret. Three fields in wp-admin, that is it.

How it works:
Queries WordPress REST API for posts modified after the last sync
Compares
modified_gmttimestamps against stored values in SQLiteNew posts (not in DB) -> fetched, converted, written as new Markdown files
Updated posts (newer
modified_gmt) -> re-fetched, re-converted, file overwrittenDeleted posts (404 from WordPress) -> local file removed, URL map cleaned up
Slug changes -> old file deleted, new file written, redirects updated
Sync workflows:
# Manual sync -- check what changed, then pull
sync_check -> sync_pull -> github_commit -> github_push
# One-command sync with auto-commit
sync_full -> github_push
# Automated daily sync via GitHub Actions
sync_schedule (platform: github-actions, interval: daily)
# Real-time sync via WordPress webhooks
sync_schedule (platform: vercel) # or netlify
# Instant webhook sync via wp-astro-bridge plugin
sync_schedule (platform: wordpress-plugin)
# Process individual post webhook
sync_webhook (validates HMAC, syncs single post)Setup Wizard (1 tool)

General
Q: Does this work with any WordPress site? Yes. It connects via the standard WordPress REST API, which is available on all WordPress sites since version 4.7. You just need a username and application password. WordPress continues running as your headless CMS backend -- nothing changes on the WordPress side.
Q: Does WordPress stay running? Yes. WordPress is the content engine. Editors continue using the WordPress admin to write posts, manage media, update pages, and handle all content operations. Astro is purely the public-facing delivery layer that serves content to visitors.
Q: How many posts can it handle?
It is designed for sites with 2,000-6,000+ posts. The SQLite-backed generation engine processes in batches with full resumability -- if it gets interrupted, just run export_resume and it picks up where it left off.
Q: Does it download media/images?
By default, no. Media stays on your WordPress server. The rewrite strategy swaps the domain in URLs for go-live (e.g., when WordPress moves to app.example.com and Astro takes over the main domain). A download strategy is planned for fully self-contained sites.
Q: What Astro version does it target? Astro 6 with hybrid rendering (static by default, SSR for preview route).
WordPress Compatibility
Q: Does it work with page builders (Elementor, WPBakery, Divi, etc.)?
Partially. Page builders store content as complex nested HTML with more markup than actual text. The REST API serves this rendered HTML, and the converter extracts the text content. However, multi-column layouts, styled sections, and visual design elements will not carry over -- you get the content, not the layout. This tool works best with standard Gutenberg or classic editor content. For page-builder-heavy sites, use convert_preview to assess quality and expect manual work on complex pages.
Q: Does it preserve Yoast/RankMath SEO data?
Yes. SEO metadata (title, description, canonical URL, OG image, robots, focus keyword) is extracted from Yoast (yoast_head_json) or RankMath (rank_math_seo) and included in the Astro frontmatter.
Q: Does it handle ACF fields?
Yes. ACF data from the REST API is normalized: images become {url, alt, width, height}, post objects become {wpId, slug, title}, repeater fields become arrays, and groups are flattened.
Q: What about custom post types? All registered post types are auto-detected and can be included in the Astro content layer. Each CPT gets its own content collection directory.
Q: Does it handle WordPress shortcodes?
Yes. Common WordPress shortcodes are handled out of the box (gallery, video, audio, caption, embed). You can configure additional shortcodes per-site with shortcode_configure -- set them to strip, keep content, remove, or map to an Astro component.
Content Sync and Ongoing Updates
Q: How do I keep the Astro frontend updated when WordPress content changes?
Use the sync tools -- they are the core day-to-day workflow. sync_check shows what changed, sync_pull fetches updates, or sync_full does everything in one command. Sync detects new posts, updated content, slug changes, and deleted posts by comparing modified_gmt timestamps.
Q: Can I automate the sync?
Yes. sync_schedule generates GitHub Actions workflows (cron-based), cron scripts, or Netlify/Vercel webhooks for real-time sync on every WordPress post save.
Q: What happens when a post is updated in WordPress?
On the next sync, the tool detects the newer modified_gmt timestamp, re-fetches the post from the REST API, re-converts it to Markdown with updated frontmatter (categories, SEO, ACF, images), and overwrites the local file. The Astro site rebuilds with fresh content.
Content Generation and Deployment
Q: Can I preview before generating the full content layer?
Yes. Run convert_preview to see 3-5 sample posts converted to Markdown. Run content_audit to see a complexity report before committing to a full build.
Q: What if the content generation fails halfway?
Every post's state is tracked in SQLite. Run export_resume to continue from where it stopped. Run export_retry to reprocess any failed posts.
Q: Does it generate redirects?
Yes. generate_redirects creates redirect rules from the WordPress->Astro URL map. Supports Netlify (_redirects), Vercel (vercel.json), Cloudflare (_redirects), Apache (.htaccess), and Nginx.
Q: Can I deploy to Vercel/Netlify/Cloudflare?
Yes. The scaffolder generates platform-specific config files, and github_deploy_config creates the deploy configuration. Push to GitHub and connect your deploy platform.
Q: Can I manage multiple sites?
Yes. Register as many WordPress sites as you want. Each site has its own config, output settings, and state. Set a default site or specify site_id per command.
Q: What happens at go-live?
WordPress moves to a subdomain (e.g., app.example.com) where it continues as the headless backend, hidden from public visitors. Astro takes over the main domain (example.com) as the fast, public-facing frontend. The media_rewrite tool handles the URL swap across all generated content.
Q: What is wp-astro-bridge? An optional WordPress plugin that ships with the project. It fires webhooks when content changes (auto-rebuilds your Astro site), rewrites the Preview button to show drafts on the Astro frontend, and exposes a normalized SEO REST field. Three PHP classes, zero dependencies.
Q: Do I need the plugin? No. The tool works without it -- you can sync content manually or via GitHub Actions cron. The plugin adds automatic rebuilds (1-2 min after publish) and draft preview. It is an upgrade path, not a requirement.
Q: What is setup_wizard?
A single command that runs the entire setup flow: register site, analyze content, configure export, preview posts, scaffold Astro project, export all content, generate redirects, and git init. Five minutes from WordPress site to deployed Astro frontend.
Technical
Q: What is the difference between router and full mode?
In router mode (default), only 3 tools are exposed to Claude: wp_astro_run, wp_astro_help, wp_astro_describe. This saves tokens. In full mode, all 57 tools are exposed directly. Set via WP_ASTRO_MODE env var.
Q: Does it handle rate limiting?
Yes. Each site has a token-bucket rate limiter (default: 10 req/s). If WordPress returns a 429, the rate is automatically halved. Configurable via rate_limit in export config.
Q: Is content sanitized for XSS?
Yes. All HTML passes through DOMPurify before conversion. Only safe tags and attributes are allowed. No <script>, onclick, or javascript: URLs survive.
Q: Where is state stored?
In a SQLite database at data/wp-astro.db (gitignored). Contains generation job state, cached terms/authors, URL mappings, shortcode rules, and audit logs. WAL mode enabled for concurrent reads.
Troubleshooting
"Authentication failed"
Verify your application password is correct (generate a new one at
/wp-admin/profile.php)Make sure the username matches exactly (case-sensitive)
Check that the REST API is not blocked by a security plugin
"Cannot connect to site"
Verify the site URL is correct and includes
https://Check that

"Page builder content looks messy"
Page builders (Elementor, WPBakery, Divi) produce deeply nested HTML -- the converter extracts text but loses layout structure
Run
convert_previewto inspect how specific posts convertFor complex builder pages, consider keeping them as HTML (
content_format: "json") or rebuilding layouts in Astro componentsStandard Gutenberg and classic editor content converts cleanly
Astro build OOM with many posts (500+)
If the generated Astro site runs out of memory during astro build, the problem is Astro's content collection parsing 500+ markdown files. Each .md file goes through Astro's markdown pipeline, which eats ~2MB per file.
Fix: Switch to JSON mode in your export config:
site_export_config -> content_format: "json"This writes a single src/data/blog.json instead of individual .md files. Astro imports the JSON directly -- no markdown parsing, no OOM. Content stays as HTML and is rendered via set:html.

Build fails with "JavaScript heap out of memory"
If the MCP server build (npm run build) runs out of memory, the problem is TypeScript compilation on CI/CD platforms with limited memory (Cloudflare Pages ~4GB, Netlify ~3GB).
Quick fix: Use the built-in memory-optimized build scripts:
npm run build # 4GB heap limit
npm run build:low-mem # 2GB heap + incremental compilationPer-platform fixes:
Platform | Solution |
Cloudflare Pages | Set build command to |
Netlify | Add env var |
Vercel | Usually fine (8GB default). If failing, add |
GitHub Actions | Add |
Still failing? Pre-build locally and commit the dist/ folder -- skip compilation on CI entirely.
See docs/faq.md for detailed CI/CD setup guides per platform.
