WordPress MCP

Manage WordPress sites through AI Engine's MCP Server. AI Engine is a free WordPress plugin that exposes a comprehensive MCP interface.

• The user needs:
• AI Engine plugin installed (free: https://wordpress.org/plugins/ai-engine/)
• MCP Server enabled in AI Engine → Settings → MCP
• A Bearer Token set in MCP settings
• Connection details should be stored in the user's TOOLS.md:
• ## WordPress MCP
• **URL:** https://example.com/wp-json/mcp/v1/http
• **Bearer Token:** <token from AI Engine MCP settings>

How to Call MCP Tools

All calls use JSON-RPC 2.0 over HTTP POST: curl -s -X POST <MCP_URL> \ -H "Authorization: Bearer <TOKEN>" \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"<tool_name>","arguments":{...}}}'

Discovery

List available tools (varies by enabled features): {"jsonrpc":"2.0","id":1,"method":"tools/list"} Always start with tools/list to discover what's enabled on this site.

Connectivity Check

{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"mcp_ping","arguments":{}}}

MCP Features (Modular)

Tools are grouped into features that the site admin enables in AI Engine → Settings → MCP Features. Only WordPress core is enabled by default. Always use tools/list to discover what's available.

Multi-Site Management

Tips

Use wp_get_post_snapshot instead of multiple calls — gets post + meta + terms in one request Use wp_alter_post for search-replace edits instead of re-uploading entire content wp_get_posts returns no full content by default — use wp_get_post for content Analytics date params use start_date / end_date (not camelCase) Always run tools/list first — available tools depend on which features the admin enabled
