SiteAgent turns every WordPress site into one an AI agent can safely operate — update, maintain, audit, and fix. Once the site is connected to Aura and its approval key is provisioned, mutating actions are gated behind human approval and recorded in a full audit trail; safe batch updates and block edits are snapshotted so they can be rolled back. It’s the on-site half of Aura, the governed control room agencies use to run whole fleets of client sites alongside their servers, CDN, and DNS. Plugin and core updates are the riskiest thing you do on a live client site. SiteAgent makes them safer: safe batch updates run behind health checks and roll back automatically if the site breaks, and every plugin in that path is zip-snapshotted first. With Aura’s approval key in place, an agent can’t silently push a change — mutating actions wait for a human to approve them. Think of it as the undo button for AI on your clients’ sites. Install this plugin on any WordPress site to connect it to Aura — no SSH, no wp-admin juggling, no manual logins. What You Can Do Monitor site health — See WordPress version, PHP version, installed plugins & themes, database info, and disk usage in real time. Update plugins, themes & core remotely — Push updates to any connected site from the Aura dashboard, no wp-admin login. Safe batch updates with auto-rollback — Run chunked updates with health checks; if an update breaks the site, the plugin restores the previous version automatically. Per-plugin rollback — Every update is zip-snapshotted first; restore any plugin to its last good state on demand. Bulk translation & database upgrades — Update all language packs and run WordPress database migrations remotely. One-click connect (magic link) — Connect a site to Aura straight from wp-admin — no manual token copy/paste. AI-agent ready (27 MCP tools) — Exposes machine-readable, JSON-schema tools for AI-driven management, including SEO/accessibility/performance/broken-link auditors, on-site SEO-meta read/write (Rank Math, Yoast, SEOPress), and Gutenberg block read/edit. Read tools run on demand; mutating tools are approval-gated through Aura, and every call is audited. Zero frontend impact — The plugin only registers REST API endpoints. No scripts, no styles, no database queries on visitor-facing page loads. How It Works After activation, click Connect to Aura on the Settings → SiteAgent page for a one-click magic-link connection, or copy the Site Token shown once and paste it into your Aura dashboard manually. From that point, Aura communicates with your site over a signed, authenticated REST API to pull health data and push updates. Security Defence-in-depth protects every request: WordPress Application Password — Standard WordPress auth with capability checks (manage_options / update_*). Only authorized administrators can trigger actions. Hashed Site Token — A per-site token sent via the X-Aura-Token header. Only a SHA-256 hash is stored (never the raw token), compared timing-safely. Tokens from older versions migrate to a hash automatically. Brute-force throttling — Repeated bad-token attempts from an IP are blocked. Signed magic-link connect — The onboarding callback is HMAC-signed with a one-time secret and timestamp, so the token exchange can’t be hijacked or replayed. IP / Domain allowlist (optional) — Restrict API access to your Aura instance, with Cloudflare and reverse-proxy header support. You can rotate the token anytime from Settings → SiteAgent → Regenerate Token. REST API Endpoints Core endpoints under /wp-json/aura/v1/: GET /status — Full site health report GET /updates — Check available updates (core, plugins, themes, translations) POST /update/core / /update/plugin / /update/theme / /update/translations — Apply updates POST /update/database — Run WordPress database upgrades POST /connect — Magic-link token exchange (public, HMAC-signed, 10-minute expiry) Version 2 endpoints under /wp-json/aura/v2/: GET /health — HTTP, PHP fatal, white-screen and DB connectivity checks POST /update/batch — Chunked batch updates with auto-rollback on health failure POST /rollback/{plugin} — Restore a plugin from its most recent backup POST /rules — Receive Aura’s signed operator ruleset; carrying unbind: true it ends this site’s binding instead While a site is disconnected by Aura, every write endpoint answers 403 aura_site_unbound and reads keep working; the disconnect answer carries cleanup_complete and leftovers (what the site still holds), and GET /status reports unbound until the site is reconnected or the remaining Aura data is removed from the settings screen. MCP tools under /wp-json/aura/mcp/: POST /tools/list / POST /tools/execute — Enumerate and run AI-agent tools GET /context — Full site context for AI decision-making AI Agent Tools (MCP) SiteAgent ships 29 built-in tools for AI agents. Read tools return information and run on demand; write tools change the site and are queued for human approval through Aura — an agent can never silently mutate a production site. Read tools: get_site_context — WordPress/PHP/theme/plugin/disk/performance snapshot with detected issues get_database_info — Database size, largest tables, autoloaded-options weight, expired transients scan_security — Scored security posture (file-edit lockdown, debug exposure, SSL, default admin/prefix, open registration, PHP version) scan_seo — SEO posture (search-engine visibility, permalinks, XML sitemap, site title) plus a sampled content audit (thin content, missing excerpts/featured images) scan_a11y — Accessibility audit over sampled content (images missing alt text, non-descriptive link text, heading structure, document language) perf_check — Performance posture (persistent object cache, OPcache, page-cache plugin, PHP version, autoload weight, active plugin count, memory limit) scan_broken_links — Link triage over a content sample with no outbound HTTP (empty/anchor-only links, dev/staging hosts, unresolved internal links) list_users — Users with roles and post counts, administrators flagged (never returns secrets) check_health — Live health gate: HTTP status, PHP fatals, white-screen, database connectivity scan_error_log — Tails and severity-groups the error log, surfacing recent fatals check_vulnerabilities — Plugin update-currency check against WordPress.org (a version check, not a vulnerability/CVE feed; covers wp.org-hosted plugins) check_core_checksums — Core-file integrity against the official WordPress.org checksum manifest (modified/missing/unexpected files, fetched over HTTPS only) scan_executable_files — Uploads-directory observations: PHP/executable files, .htaccess overrides, and symlinks (reported, never followed) audit_admin_accounts — Privileged-account facts: administrators with recency, admin capabilities outside the role, application-password counts, multisite super admins audit_cron — Bounded WP-Cron inventory with sub-60-second-schedule and unresolved-callback fact-flags audit_mcp_exposure — Which other MCP servers are registered on this site, and how many abilities pass the discovery rule such a server applies (abilities are registered site-wide, not per-plugin, so a server resolving targets from that registry picks up mutating ones outside SiteAgent’s approval path). The counts describe the abilities, not what any server currently serves. Reports only; changes nothing audit_agent_code — Executable code an AI agent authored or can author on this site: Angie code snippets (recorded, agent-authored, live per environment), the SiteAgent Power Pack’s execute-php / file-write / wp-cli flags, and third-party exec stores. Counts and presence only; never file contents, never a verdict. Reports only; changes nothing audit_rules — Whether a signed operator ruleset is present and how old it is, 24h block/warn counts, expired-but-listed rules, and the enforcement points in this build. Reports only; changes nothing get_seo_meta — Read a post/page’s SEO title, description, and focus keyword from the active SEO plugin (Rank Math, Yoast, or SEOPress) list_page_blocks — Read a page’s Gutenberg block structure (block names, attributes, nesting) snapshot_get — Retrieve a stored snapshot of page content (reversible write metadata) Write tools (approval-gated): elementor_replay_ability — Executes an approved held Elementor write (destructive, requires Aura approval): claims the hold, re-judges it against the current ruleset, and runs the original Elementor mutation as the user who asked update_plugin_safely — Backup, update, health-check, auto-rollback on failure clear_caches — Flush object/opcode caches and detected page-cache plugins cleanup_transients — Remove expired transients to reduce autoload bloat cleanup_orphaned_assets — Find and remove unused media (dry-run by default) backup_plugins — Zip-snapshot one or all active plugins as a rollback safety net set_seo_meta — Write a post/page’s SEO title / description / focus keyword on the active SEO plugin (Rank Math, Yoast, or SEOPress) — on-site, so it works even when a WAF blocks the plugin’s own REST endpoint update_page_block — Update a Gutenberg block’s content or attributes (snapshot-first, reversible) create_page_from_blocks — Create a new page from a Gutenberg block spec (draft-first) Tools are classified by verb so the Aura Fleet gateway applies the right risk and approval policy automatically. Pro: the SiteAgent Power Pack Everything above is free and ships in this plugin. Agencies that need an agent to fix a site — not just report on it — can add the SiteAgent Power Pack, a separate companion plugin that registers higher-capability tools through this plugin’s own tool registry. It is not included in this download and is not distributed on WordPress.org — the tools it adds execute code, so they don’t belong in a hosted repository. It comes with the Aura Agency and Studio plans, or as SiteAgent Pro. What it adds: read_file — read a text file from inside wp-content (jailed; refuses wp-config.php). db_query — a single read-only SQL statement (SELECT / SHOW / EXPLAIN), row-capped. write_file — write a file inside wp-content, snapshot-first so it can be rolled back. run_wp_cli — run an allowlisted WP-CLI command, with no shell and no metacharacters. execute_php — run a PHP snippet against the full WordPress API. These are governed harder than anything in the free set, deliberately: Off until you arm them. The write and code tools do nothing until the site owner sets an explicit constant in wp-config.php for each one. Installing the Power Pack alone enables no writes and no code execution. Human approval, cryptographically enforced. Once the site holds Aura’s approval key (provisioned when you connect the site), each of these calls requires a single-use, signed grant bound to that exact tool and its exact parameters — one only the Aura dashboard can mint, after a human approves the action. A leaked Site Token cannot run them. (Until a site has that key, the gate is dormant — so connect the site from Aura before arming anything.) Reversible where it can be. File writes are snapshotted first, so there’s a previous state to restore. The safety model is governance, not a sandbox: execute_php is powerful by design. The controls are the constant you set, the human who approves the call, and the audit trail — not a promise that arbitrary code is safe. Learn more at my-aura.app/siteagent.
