About this plugin
Invocation is a self-hosted, open-source AI assistant for the WordPress block editor. json design tokens, and section patterns into valid, on-theme Gutenberg layouts.
Features:
- Generate a section or a full page from a prompt, grounded in your theme.
- Fill a chosen section pattern with real content.
- Refine any block in place from the editor toolbar.
- Uses real media and real internal links — never invented URLs.
- A Site Brief that keeps every generation on-brand.
- A built-in MCP server — drive everything from AI agents like Claude Code, with no extra plugin to install.
- A Connect tab that links the site to Claude Desktop or Claude Code in a couple of clicks.
Everything runs on your server. No external service, database, or Docker required. Capabilities are registered as WordPress Abilities, so they are also available over REST and to MCP agents.
External services
0 core under Settings → Connectors (for example OpenAI, Anthropic, or Google). When you trigger a generation, refinement, or “generate Site Brief” action, the plugin sends your prompt plus relevant context from your own site (such as your theme’s design tokens, the names of your registered blocks and patterns, titles/URLs of your published pages, and media metadata) to that provider through core’s AI Client in order to produce block markup.
No data is sent unless you take one of these actions, and the plugin itself transmits nothing to any other external service. Your AI provider credentials are managed by WordPress core Connectors, not by Invocation.
Review the terms and privacy policy of whichever AI provider you connect before sending content. Those policies are published by the provider you choose (for example OpenAI, Anthropic, or Google), not by Invocation.
Development
Invocation is open source. The block-editor UI is built from the JavaScript sources in src/ (bundled with the plugin) using @wordpress/scripts — run npm install && npm run build to regenerate build/. com/invocation97/invocation
