No data is sent to external servers. Abilities API VigIA is one of the first WordPress plugins to implement the Abilities API introduced in WordPress 6.9. This API allows AI agents, automation tools, and external systems to discover and interact with VigIA’s functionality in a standardized, secure way. What are Abilities? Abilities are self-contained units of functionality that VigIA exposes through WordPress’s central registry. Each ability has defined inputs, outputs, and permissions, making it easy for automation tools to understand and use them. Available Abilities VigIA registers the following abilities: Analytics vigia/get-crawler-stats – Get statistics about AI crawler visits (total visits, unique crawlers, pages crawled) vigia/get-top-crawlers – Get a ranked list of most active AI crawlers vigia/get-top-pages – Get the most crawled pages on your site Blocking vigia/get-blocked-items – List all blocked crawlers and IP addresses vigia/block-crawler – Block a crawler by User-Agent pattern vigia/unblock-crawler – Remove an existing block Robots.txt vigia/get-robots-rules – Get current AI crawler rules in robots.txt vigia/add-robots-disallow – Add a Disallow directive for a crawler vigia/remove-robots-rule – Remove a robots.txt rule Use Cases Automated monitoring: AI agents can query crawler statistics and alert you to anomalies Reactive blocking: Automation tools can block crawlers that repeatedly ignore robots.txt External dashboards: Aggregate data from multiple WordPress sites with VigIA installed WP-CLI integration: Future command-line access through the Abilities API n8n / Make workflows: Build custom automation flows using VigIA’s abilities Requirements The Abilities API ships with WordPress 6.9 and later. On older WordPress versions, VigIA works normally but abilities and MCP are not available. MCP Server (Model Context Protocol) VigIA exposes its 9 abilities as native MCP tools to any MCP-compatible client (Claude Code, Cursor, Claude Desktop, Codex CLI, Antigravity, Continue, Cline, Zed and similar) using the official WordPress MCP Adapter. The adapter ships bundled with the plugin, so the MCP endpoint is active right after installation — no Composer step or terminal access required. Requirements WordPress 6.9 or later (provides the Abilities API) Quick connect (recommended) Open VigIA > Extras > MCP and click “Generate password and connection commands”. The plugin creates a dedicated Application Password named VigIA MCP and renders ready-to-paste commands for Claude Code, Cursor, Claude Desktop and a generic block (URL + Authorization header) for any other MCP client. The plain password is shown only once. If you lose it, revoke the entry from the same panel and generate a new one. Endpoint https://your-site.example/wp-json/vigia/v1/mcp The endpoint uses HTTP Basic auth with the WordPress Application Password. The user must have the manage_options capability. Connecting Claude Code Quick Connect builds the full command for you. The shape is: claude mcp add --transport http vigia https://your-site.example/wp-json/vigia/v1/mcp --header "Authorization: Basic BASE64_OF_USER_AND_APP_PASSWORD" Claude Code merges the new entry into its config file automatically — no risk of breaking other servers. Connecting Cursor Save the JSON block from Quick Connect as ~/.cursor/mcp.json. You can also reach this file from inside Cursor at Settings → Cursor Settings → MCP. If the file already exists with other content, see the FAQ. Claude Desktop and other clients Claude Desktop does not speak HTTP MCP, so it needs a small bridge and a config file of its own. Any other client (Codex CLI, Continue, Cline, Antigravity, Zed, or your own) takes the two raw values Quick Connect exposes: the server URL and the Authorization header. Both cases are covered in the FAQ, together with how to merge VigIA into a config file that already exists without losing what is in it. Read-only mode If you only want your AI to consult VigIA (not change anything), enable “Read-only mode” in the MCP tab. While on, write actions (block, unblock, robots changes) return a permission denied error. Read actions (statistics, top crawlers, blocked items, robots rules) keep working. The toggle stores a vigia_mcp_read_only option that hooks into the vigia_can_write_via_abilities filter. Developers can still force read-only from a mu-plugin: add_filter( 'vigia_can_write_via_abilities', '__return_false' ); The mu-plugin filter at the default priority takes precedence over the toggle. Who can reach the endpoint The endpoint requires the capability to manage options, the same one every tool behind it already asked for. The vigia_mcp_transport_capability filter can lower that bar; each tool keeps its own permission check. After connecting Restart your MCP client after adding the server so it picks up the new tools. Then try a few prompts to confirm everything is wired up: “Show me VigIA crawler stats for the last 7 days.” “List the top 5 most crawled pages on this site.” “Add a robots.txt Disallow rule for TestBot and then list the current AI crawler rules.” The third example exercises a read + write + read round-trip, which is the most complete sanity check.
