How to Use WEBO MCP with WordPress: AI Integration Guide

What Is WEBO MCP?

WEBO MCP is a WordPress plugin that turns a WordPress website into an MCP-compatible server. MCP, short for Model Context Protocol, gives AI clients a standard way to discover available tools and call those tools with structured JSON arguments.

After the plugin is installed and activated, your site exposes a JSON-RPC router endpoint:

https://yourdomain.com/wp-json/mcp/v1/router

An AI client can use this endpoint to start a session, inspect available WordPress tools, and run permitted actions such as creating drafts, reading posts, updating content, uploading media, assigning taxonomy terms, or checking site settings.

Why Use WEBO MCP for WordPress Automation?

WEBO MCP is useful when you want AI tools to work with WordPress in a controlled and repeatable way. It is especially helpful for editorial workflows, SEO content updates, content audits, media tasks, and internal automation.

5 MCP Trend Keywords to Watch

As Model Context Protocol adoption grows, these MCP trend keywords are worth including in your WordPress automation and AI integration strategy:

• Remote MCP servers: Hosted MCP endpoints that let agents connect to tools and data over secure HTTP transports instead of local-only integrations.
• MCP security: Authentication, permission boundaries, tool approval, audit logs, and safer execution policies for agentic workflows.
• MCP connectors: Reusable integrations that expose apps, databases, documentation, CRMs, CMS platforms, and developer tools to AI clients.
• Agentic AI workflows: Multi-step automations where AI agents discover tools, call them, recover from errors, and complete real business tasks.
• Enterprise MCP governance: Policies for tool access, data boundaries, compliance, monitoring, and lifecycle management across large organizations.

For WordPress teams, these trends point toward a practical future: AI assistants that can safely draft, optimize, update, classify, and maintain content through controlled MCP tools.

Requirements

Before connecting an AI tool to WordPress with WEBO MCP, prepare these items:

• A WordPress site with WEBO MCP installed and activated.
• A WordPress user account with the required capabilities for your workflow.
• A WordPress Application Password for API authentication.
• An MCP-compatible client, automation workflow, coding agent, or script that can send JSON-RPC requests.

For production sites, create a dedicated automation user. Give that user only the permissions needed for the task. For example, a content assistant may need permission to read and edit posts, but it usually does not need full administrator access.

Step 1: Create a WordPress Application Password

WEBO MCP can authenticate requests with WordPress Application Passwords. This is safer than sharing your normal login password because each application password can be revoked independently.

1. Open the WordPress dashboard.
2. Go to Users and open the profile for the automation account.
3. Find the Application Passwords section.
4. Create a new password for your MCP client.
5. Store the generated password securely because WordPress shows it only once.

Your MCP client should send HTTP Basic Authentication. Use the WordPress username as the username and the generated Application Password as the password.

Step 2: Initialize an MCP Session

The first JSON-RPC request should call the initialize method. A successful response returns a session_id. Later tool calls must include that session ID.

{
  "jsonrpc": "2.0",
  "method": "initialize",
  "params": {
    "client": "my-ai-client",
    "version": "1.0"
  },
  "id": 1
}

A successful response looks similar to this:

{
  "jsonrpc": "2.0",
  "result": {
    "session_id": "your-session-id",
    "capabilities": {
      "tools": true,
      "methods": ["initialize", "tools/list", "tools/call"]
    }
  },
  "id": 1
}

Step 3: List Available MCP Tools

Use tools/list to discover which WordPress tools are available to the authenticated user. This is an important step because tool availability can change based on permissions and site policy.

{
  "jsonrpc": "2.0",
  "method": "tools/list",
  "params": {
    "session_id": "your-session-id"
  },
  "id": 2
}

A read-only user may only see tools for viewing content. An editor or administrator may see tools for creating, updating, or managing content.

Step 4: Call a WordPress Tool

After discovering available tools, call tools/call with the tool name and arguments. The example below lists recent published posts:

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "session_id": "your-session-id",
    "name": "webo/list-posts",
    "arguments": {
      "post_type": "post",
      "status": "publish",
      "per_page": 10
    }
  },
  "id": 3
}

WEBO MCP validates the request, checks the session, confirms permissions, and then runs the registered WordPress tool callback.

Common WEBO MCP Tools

The exact list depends on the site configuration, but common WEBO MCP tools include:

• webo/list-posts: List posts, pages, or custom post types by status and type.
• webo/get-post: Retrieve title, content, excerpt, status, slug, and link for a single post.
• webo/create-post: Create a new post, page, or custom post type.
• webo/update-post: Update an existing post and optionally change its status.
• webo/list-media: List media library items.
• webo/upload-media-from-url: Import an image or media file from a URL.
• webo/list-terms: List categories, tags, or taxonomy terms.
• core/get-site-settings: Inspect site identity, URLs, reading settings, permalinks, and active theme data.

Example Workflow: AI-Assisted Content Updates

A practical WordPress automation workflow with WEBO MCP can follow this sequence:

1. The AI client initializes a session.
2. The client calls tools/list to confirm available actions.
3. The client calls webo/list-posts to find drafts or published posts.
4. The client calls webo/get-post to read a specific article.
5. The client rewrites or improves the article structure, SEO headings, and formatting.
6. The client calls webo/update-post to save the improved draft or publish the final version.

This workflow keeps the process auditable. The AI performs repeatable content operations, while WordPress still controls authentication, capabilities, revisions, and publishing status.

Security Best Practices

Because WEBO MCP can expose powerful WordPress actions, configure access carefully.

• Use a dedicated WordPress user for automation.
• Grant only the capabilities required for the workflow.
• Use Application Passwords and revoke unused passwords.
• Review tool access before enabling actions that publish, delete, or bulk update content.
• Keep WordPress core, themes, plugins, and WEBO MCP updated.
• Use additional API key or HMAC controls if your environment requires stricter request validation.

Troubleshooting

The MCP client cannot authenticate

Confirm that the username is correct and that the password is the WordPress Application Password, not the normal account password. Also check that your server passes the Authorization header to WordPress.

The tool list is empty

The authenticated user may not have enough permissions, or the site may restrict public tool categories. Test with a properly permissioned user, then reduce access after confirming the workflow.

A tool call returns an invalid session error

Call initialize first and pass the returned session_id into later requests. Do not reuse an expired or unrelated session value.
