Elementor Agent

npm version License: MIT Mogacode-ma/elementor-mcp-agent MCP server GitHub stars

Agency-grade MCP server for WordPress Elementor. Multi-site management, safe Elementor edits with backup + auto-rollback + CSS flush, template export/import, global widget detection, screenshots, WP-CLI escape hatch.

Built for agencies running many client sites on Elementor / Elementor Pro who want Claude (or any MCP client) to drive the toil — without breaking pages.

How this was built

elementor-mcp-agent was built end-to-end with Claude Code over ~48 hours. The process is intentionally open:

• Architecture, code, tests, docs — all generated through Claude Code pair-programming sessions
• The 7 bugs documented in this post-mortem were caught in real E2E testing against a live WordPress + Elementor install, not after the fact
• v1.2's post-write verification pattern was shipped 2 hours after a reader's comment (Mads Hansen on Dev.to) — the changelog credits the source

This isn't vibe-coded software thrown over the wall. Every release ran through lint + typecheck + 27 unit tests + (for v1.0) full E2E against a real WordPress install before publishing. The MCP itself hardcodes guardrails that prevent the model from making destructive WP-CLI calls.

I run a small WordPress agency and use this tool every day on client sites. If you're skeptical about agentic codegen for production infrastructure, the entire commit history is in the open — judge for yourself.

Why this exists

There are 25+ WordPress MCP servers on GitHub today. None targets the agency multi-site workflow with:

• Real backup before every edit (postmeta via WP-CLI when SSH available, JSON file fallback — never silently lost)
• Two-call confirmation for any destructive op (TTL 60s)
• JSON validation + auto-rollback if an edit produces invalid Elementor data
• 3-level CSS flush fallback (REST → wp-cli native → option/meta delete → re-save)
• Global widget awareness — preflight check warns if a page references shared widgets
• WP-CLI escape hatch for everything the REST API can't do safely
• Screenshots via headless Chrome (no puppeteer dep)

Install

npx -y elementor-mcp-agent

Configure

export ELEMENTOR_MCP_SITES='[{
  "id": "client-acme",
  "url": "https://acme.example.com",
  "username": "admin",
  "application_password": "xxxx xxxx xxxx xxxx xxxx xxxx",
  "ssh": {
    "host": "host.example.com",
    "user": "username",
    "port": 22,
    "path": "/path/to/wordpress",
    "wp_cli_path": "wp"
  }
}]'

Generate the WordPress Application Password at https://{your-site}/wp-admin/profile.php#application-passwords-section.

The ssh block is optional but unlocks 8 additional tools (WP-CLI escape hatch + reliable custom-postmeta backups). The MCP works without SSH — backups go to local JSON files instead.

wp_cli_path auto-detects if omitted (tries wp, then ~/bin/wp.phar, then ~/wp-cli.phar).

Widgets (v1.1 — widget-level CRUD)

• read_widget — fetch one widget by id (read-only)
• update_widget_settings — shallow-merge settings, with backup + validate + flush
• delete_widget — remove a widget from its parent container
• duplicate_widget — clone as sibling with fresh id

• add_widget — append a widget into a parent container
• move_widget — move a widget between containers (with position)

Bulk & fleet (v1.1)

• restore_from_file — restore _elementor_data from a JSON file backup, with pre-restore safety backup

Fleet

• check_elementor_versions — flag outdated installs against wordpress.org latest

Post-write verification (v1.2)

Every mutating widget tool re-reads the page from canonical WP after the write and surfaces persisted state to the model. The HTTP write API can lie — return 200 OK while plugin filters or REST quirks silently drop the payload. This contract makes that observable.

Every applied response carries:

{
  "mutated": true,                  // false = no-op OR silent drop
  "warnings": [],                   // non-fatal issues
  "verification": {
    "method": "Re-read /wp/v2/pages/42 and check widget abc settings…",
    "reread_ok": true,
    "matches_requested": true,      // false = write API lied
    "persisted": { /* canonical state */ },
    "notes": "…explanation when something diverged"
  }
}

If verification.matches_requested === false, treat as a failure even if the HTTP layer said OK. The original payload survives in backup_meta_key — restore via restore_elementor_backup.

Safety guarantees

Hardcoded in src/elementor/policies.ts:

BACKUP_BEFORE_WRITE                 = true
BACKUP_PAGE_SETTINGS                = true
VALIDATE_JSON_AFTER_EDIT            = true
BLOCK_GLOBAL_WIDGET_WRITES_BY_DEFAULT = true
CONFIRMATION_TTL_SECONDS            = 60
GLOBAL_WIDGET_CONFIRMATION_TTL_SECONDS = 30
FLUSH_CSS_AFTER_WRITE               = true
MAX_ELEMENTOR_DATA_BYTES            = 5_000_000

And these wp-cli patterns are hard-blocked regardless of confirmation:

• rm -rf
• sudo *
• db reset --yes / db drop --yes

End-to-end verified

v1.0.0 was tested in real conditions against a live WordPress install with Elementor 4.0.9:

• ✅ 21/24 tools validated end-to-end
• ✅ find_replace → backup → restore round-trip preserves data
• ✅ duplicate_page copies data + page_settings + edit_mode
• ✅ apply_template_to_page with auto-backup
• ✅ wp_cli_run destructive flow (post delete) requires confirmation
• ✅ screenshots identical detection via SHA-256
• ✅ CSS flush uses wp elementor flush-css when SSH available, falls back to option-delete otherwise

7 bugs found during testing, all fixed:

• REST API silently drops unregistered postmeta writes → switched to WP-CLI primary for backups
• wp not in SSH PATH on managed hosts → auto-detection + wp_cli_path config
• SSH post-quantum banner pollution → stderr filter
• Default Kit returned as "widget" → client-side filter
• _elementor_page_settings type object/string mismatch → normalisation
• Chrome cold-start screenshot timeout → bumped to 60s
• Templates listing same filter bug → fixed

If this saved you time

The fastest way to support the project is a ⭐ star on GitHub — it helps other agencies running Elementor sites find this and tells me what to keep building.

You can also:

• Open an issue for bugs, edge cases, or missing tools
• Start a discussion for design or workflow questions
• Share what you built with it — I'd love to hear
