WEBO MCP vs SEOPress – AI SEO Plugin & On-site SEO

WEBO MCP is a WordPress MCP server — a complete Model Context Protocol gateway for WordPress. It lets AI agents and MCP-compatible clients (Claude Desktop, Cursor, Windsurf, n8n, and more) call well-defined tools over REST using JSON-RPC, instead of scraping the admin or sharing broad credentials. Official WEBO MCP website, documentation, and ecosystem hub: https://webomcp.com Why use WEBO MCP as your WordPress MCP server? Token-optimized unified tools: every domain exposes two abilities — *-query (all reads) and *-mutate (all writes) — with a single action discriminator. tools/list payload is up to 70% smaller than per-operation APIs, which means less of the model’s context window is consumed by tool schemas, lower cost per session, and fewer hallucinated tool names. Primary router endpoint: POST /wp-json/mcp/v1/router Standard MCP-style flow: initialize → tools/list → tools/call Session lifecycle for clients (pass session_id or Mcp-Session-Id after initialize) Built-in tool registry for common WordPress operations (posts, media, terms, menus, options, and more) Bundled Abilities API + MCP Adapter integration, with automatic bridging from registered abilities to MCP tools (configurable) WordPress 7.0/Core-aware bridge mode that uses Core Abilities/API surfaces when available and falls back only when needed Public tool policy controls (category filters and optional allowlists) plus optional internal tool exposure for private environments Bounded MCP audit log, optional per-user/role/client tool allowlists, and a read-only administrator health/status tool Security model (high level) MCP access requires a real WordPress user context: Application Password over HTTP Basic, or an existing logged-in session. Optional site-wide or per-user API key and HMAC can be enabled in Settings as an additional gate (they do not replace WordPress authentication). Generate/rotate from Settings → Security; by default they are skipped for Application Password and Bearer clients unless you enable “Require for App Password / Bearer”. Do not put the normal WEBO API key in URLs. For clients that cannot send headers, create a short-lived scoped mcp_token URL connector token in Settings -> WEBO MCP. Default access expectations for the router and GET /wp-json/webo-mcp/v1/tools: users who are super admins, can manage_options, or can edit_posts, consistent with typical site operator and editor workflows (filterable). Client guidance Always discover tools before calling them: run tools/list, pick an exact tool name from the response, validate required arguments, then call tools/call. This reduces mistakes and keeps automation predictable in production. Further documentation and optional integrations Official website, documentation, and ecosystem notes: https://webomcp.com Optional n8n community node (separate package): https://www.npmjs.com/package/n8n-nodes-webo-mcp Release notes and migration map: see docs/RELEASE_NOTES_2.1.0.md and docs/MIGRATION_GUIDE_2.1.0.md in the GitHub repository Cross-addon dispatcher map (granular legacy names removed from discovery): docs/MCP_TOOL_MIGRATION.md Compatibility note: any MCP-capable client can be used; which large language model runs inside the client is outside this plugin. Standalone core tools included: – Site info – Content (posts/pages): webo/content-query (list, get, find-by-url, search-replace, list-revisions, get-revision; with author/date/taxonomy filters) and webo/content-mutate (create, update, delete, bulk-update-status, restore-revision, change-author) – Users: webo/list-users and webo/user-mutate (add-to-blog, set-role) – Media: webo/media-query (list with search/MIME/post_id filters, get) and webo/media-mutate (upload, update, delete) – Comments: webo/comment-query (list, get) and webo/comment-mutate (create, update, delete) – Taxonomy/Terms: webo/taxonomy-query (discover, list, get) and webo/taxonomy-mutate (create, update, delete) – Nav menus: list menus, list menu items (menu_order, db_id), add menu link from post (explicit post_id + menu_order required) – Plugins: webo/plugin-query (installed, active, updates, …) and webo/plugin-mutate (install, activate, deactivate; supports child-site site_id / blog_id activation for network admins) – Health: webo/health-status (REST/router status, Application Password support, permalinks, cron, object cache, plugin update summary, WordPress/PHP versions, and redacted MCP config) – Client health: webo/client-health-report (score 0–100, grade A–D, Markdown scoreboard for agency clients; hybrid foundation for Pro collectors later) – 404 logs: webo/get-404-logs (read-only Rank Math / Redirection 404 monitor: url, hits, accessed, referrer) – Abilities bridge: webo/ability-query and webo/ability-execute in default layered mode. Only abilities with meta.mcp.public === true are visible and executable through WEBO MCP. – Themes: webo/theme-query (installed themes) and webo/theme-mutate (install from WordPress.org by slug, switch installed theme) – Theme context: webo/theme-context (active theme info, block editor settings, style presets, registered blocks) – Block patterns: webo/block-patterns (list/get patterns, list/get synced patterns) – Site stats: webo/site-stats (overview, post counts, comment counts, user counts, media stats, activity summary) – Activity log: webo/activity-log (list events, summary, clear) – User profile: webo/user-profile (get own profile, update display name / bio / preferences) – Site settings: webo/site-settings (get and update the 20 most common WordPress options via MCP) – Content search: webo/content-search (full-text cross-post-type search with grouped results) – Menus: webo/menu-query, webo/menu-mutate (navigation menu items; not post/CPT list order) – Post/CPT order (optional): webo/reorder-query, webo/reorder-mutate when Webo Reorder is active — see docs/abilities/reorder.md – Options: get/update (safe allowlist only), set site icon/favicon from media – SEO (WordPress post): seo/article-analysis — requires post_id; merges Rank Math meta when available (same data path as webo-rank-math/get-post-seo-meta); optional related-keyword suggestions via outbound request unless no_autocomplete is true Excluded by default in standalone-safe mode: – Bulk/mass execution tools – Plugin/theme write-management abilities – Multisite-specific abilities Privacy This plugin does not phone home or send telemetry. MCP traffic is initiated by clients you configure. Some tools may perform outbound HTTP requests only when a client invokes them (for example seo/article-analysis may request keyword suggestions from a third-party suggest API unless you pass no_autocomplete). The plugin stores the following options in the WordPress database when configured: – webo_mcp_api_key: API key used to authenticate MCP requests. – webo_mcp_hmac_secret: HMAC secret used to sign and validate MCP requests. – webo_mcp_require_secondary_credentials: when enabled, also require API key/HMAC for Application Password and Bearer clients (off by default so standard connectors are not blocked). – webo_mcp_url_connector_tokens: hashed, expirable, revocable URL connector tokens for clients that cannot send headers. Raw tokens are shown once and are not stored. – webo_mcp_tool_allowlist_enabled and webo_mcp_tool_allowlist_rules: optional administrator-configured MCP tool allowlist policy. – webo_mcp_audit_log_enabled, webo_mcp_audit_log_max_entries, and webo_mcp_audit_log: bounded MCP tool-call audit log settings and compact audit events. Audit entries include user/tool/action/status data, anonymized IPs, and hashed session IDs; they do not store request payloads, API keys, HMAC secrets, or Application Passwords. – webo_mcp_installed_at and webo_mcp_review_notice: local timestamps/state for an optional WordPress.org review request notice (not sent off-site; dismissible). These options are removed when the plugin is uninstalled via the WordPress Plugins screen. External services This plugin can connect to Google Suggest (Autocomplete) when a client calls the seo/article-analysis tool and does not set no_autocomplete to true. This external request is used to return related keyword suggestions for SEO analysis. Service provider: Google LLC (Google Suggest / Autocomplete API endpoint). Data sent and when: – Sent only when seo/article-analysis is called with autocomplete enabled. – Sends the analysis query text to https://suggestqueries.google.com/complete/search as the q parameter. – Sends standard HTTP request metadata such as IP address and User-Agent as part of the web request. Terms of Service: https://policies.google.com/terms Privacy Policy: https://policies.google.com/privacy Developer Hooks The plugin exposes the following actions and filters for developers: Actions webo_mcp_register_tools Fired during plugin bootstrap after standalone tools are registered.

Default true for Application Password (Basic) and Bearer sessions unless Settings → Security → “Require for App Password / Bearer” is enabled. Return false to always enforce X-WEBO-* headers. webo_mcp_allow_internal_tools (bool $allow_internal, WP_REST_Request $request) Controls whether internal tools are included in tools/list responses. Defaults to false for public environments. webo_mcp_public_categories (array $categories, WP_REST_Request $request, array $tool) Filters which tool categories are exposed as public.

Defaults to true; bridge mode still controls whether the bridge is off, layered, or full. webo_mcp_bridge_mode (string $mode) Controls Abilities bridge mode after the WEBO_MCP_BRIDGE_MODE constant and before the stored option. Values: off, layered, full. Default: layered. webo_mcp_enable_adapter (bool $enabled) Enables or disables the bundled WordPress MCP Adapter runtime. Defaults to true. webo_mcp_validate_media_fetch_url (true|\WP_Error $ok, string $url, array $parsed) Reject unsafe URLs for webo/media-mutate upload action (return WP_Error to block). webo_mcp_tool_allowlist_allowed (bool $allowed, string $tool_name, WP_REST_Request $request, array $params, array $allowed_tools) Filters the optional per-user/role/client allowlist decision.
