 == Frequently Asked Questions ==
 
-= What is the REST API endpoint to create posts? =
-Use `/wp-json/api-post-creator/v1/create-post` with a POST request and appropriate parameters.
+= Do I need an AI API key to use the plugin? =
 
-= How do I authenticate requests? =
-Use application passwords and pass them using the Basic Auth header.
+No. The free version works without any API keys. AI features (content generation, rewriting, auto-SEO) require a Claude or OpenAI API key and a Pro license.
 
-= What SEO plugins are supported? =
-SEOPress, Yoast SEO, and Rank Math. The plugin auto-updates the correct meta fields.
+= Which SEO plugins are supported? =
 
-= Can I search for similar post titles before publishing? =
-Yes! Use the `/search-similar-posts` endpoint to retrieve related posts for internal linking or avoiding duplicates.
+SEOPress, Yoast SEO, and Rank Math. The plugin auto-detects which one is active and writes meta data accordingly. It also writes to all three for maximum compatibility.
+
+= Is the REST API secure? =
+
+Yes. All write endpoints require JWT or Basic Auth. Rate limiting is configurable. Read-only endpoints (search, categories, status) are public by design.
+
+= Can I use custom post types? =
+
+Yes. Both `create-post` and `search-similar` accept a `post_type` parameter. Any registered public post type is supported.
+
+= What is MCP? =
+
+Model Context Protocol is an open standard for connecting AI models to external tools. With our MCP server, Claude Desktop, Cursor, and other AI agents can create posts, search content, and generate articles directly on your WordPress site.
+
+= Are v1 endpoints still supported? =
+
+Yes. Legacy endpoints under `api-post-creator/v1/` continue to work for backward compatibility.
 
 == Screenshots ==
 
-1. **Admin Page Interface** – Displays all endpoints with copy buttons.
-2. **API Example Payload** – Demonstrates JSON structure to create a post.
-3. **Similarity Response** – JSON listing similar titles by relevance.
+1. Admin page — Endpoints tab with copy-to-clipboard URLs
+2. Admin page — Settings with AI provider configuration
+3. Admin page — MCP Server setup with Claude Desktop config
+4. Admin page — License activation

 == Frequently Asked Questions ==
 
-= What is the REST API endpoint to create posts? =
-Use `/wp-json/api-post-creator/v1/create-post` with a POST request and appropriate parameters.
+= Do I need an AI API key to use the plugin? =
 
-= How do I authenticate requests? =
-Use application passwords and pass them using the Basic Auth header.
+No. The free version works without any API keys. AI features (content generation, rewriting, auto-SEO) require a Claude or OpenAI API key and a Pro license.
 
-= What SEO plugins are supported? =
-SEOPress, Yoast SEO, and Rank Math. The plugin auto-updates the correct meta fields.
+= Which SEO plugins are supported? =
 
-= Can I search for similar post titles before publishing? =
-Yes! Use the `/search-similar-posts` endpoint to retrieve related posts for internal linking or avoiding duplicates.
+SEOPress, Yoast SEO, and Rank Math. The plugin auto-detects which one is active and writes meta data accordingly. It also writes to all three for maximum compatibility.
+
+= Is the REST API secure? =
+
+Yes. All write endpoints require JWT or Basic Auth. Rate limiting is configurable. Read-only endpoints (search, categories, status) are public by design.
+
+= Can I use custom post types? =
+
+Yes. Both `create-post` and `search-similar` accept a `post_type` parameter. Any registered public post type is supported.
+
+= What is MCP? =
+
+Model Context Protocol is an open standard for connecting AI models to external tools. With our MCP server, Claude Desktop, Cursor, and other AI agents can create posts, search content, and generate articles directly on your WordPress site.
+
+= Are v1 endpoints still supported? =
+
+Yes. Legacy endpoints under `api-post-creator/v1/` continue to work for backward compatibility.
