My first MCP Server: WordPress Plugin Directory for LLMs

A few days ago I started developing my own JWT authentication plugin for WordPress sites using my own approach and criteria for client-side workflows.

The result has been jwt-auth-pro-wp-rest-api — a plugin I’m really happy with in terms of code quality and functionality.

When considering publishing it to the WordPress.org directory, I wanted to understand what value my plugin would provide compared to existing similar plugins. However, Claude Code couldn’t effectively compare my plugin with others in the repository without additional tooling. I wanted to compare not only features but also code.

That challenge sparked the creation of this MCP server — a way to enable real-time WordPress plugins intelligence and comparison capabilities for LLMs.

Spoiler: After building this tool and running the comparison, I was thrilled to discover that my plugin offered genuine value to the developer community! 🎉 See details below

Real Use Case with Claude Code: Compare JWT Authentication Plugins
Try It Yourself

WordPress Plugins Directory MCP server

I’m excited to announce wordpress-org-mcp-server — an open-source local MCP server that enables tools like Claude Code to work with live data from the WordPress.org plugin directory.

The GitHub repository of the project is juanma-wp/wordpress-org-mcp

This project exposes a local Message Control Protocol (MCP) server that allows LLM-powered coding tools to search, download, extract, and analyze real WordPress plugins — safely and intelligently.

With this server, you enable your local AI tool to read and reason over real plugin code, metadata, readmes, and even compare plugin architectures securely and locally.

What It Can Do

The server exposes these MCP tools to your LLM:

Tool	Description
`search_plugins`	Query WordPress.org plugin directory
`get_plugin_info`	Retrieve plugin metadata (name, version, author, etc.)
`download_plugin`	Download plugin ZIP
`extract_plugin`	Extract plugin files to local temp dir
`list_plugin_files`	List extracted plugin files
`read_plugin_file`	Read and parse any plugin file
`get_plugin_readme`	Extract plugin readme sections
`get_plugin_ratings`	Get plugin rating summary & review count

Real Use Case with Claude Code: Compare JWT Authentication Plugins

Here’s an actual conversation, from my plugin’s folder, showing how Claude Code uses this MCP server to analyze and compare WordPress plugins with real code inspection:

🧑 Me: What are the most rated JWT plugins in the WordPress.org directory?

🤖 Claude: I’ll search for JWT plugins in the WordPress.org directory to find the most highly rated ones.

wordpress-org - search_plugins (MCP)(query: "JWT authentication", limit: 20)
wordpress-org - search_plugins (MCP)(query: "JWT", limit: 20)
wordpress-org - search_plugins (MCP)(query: "JSON Web Token", limit: 15)

wordpress-org - search_plugins (MCP)(query: "JWT authentication", limit: 20)
wordpress-org - search_plugins (MCP)(query: "JWT", limit: 20)
wordpress-org - search_plugins (MCP)(query: "JSON Web Token", limit: 15)

After trying multiple searches, Claude directly checked known JWT plugins:

wordpress-org - get_plugin_info (MCP)(slug: "jwt-authentication-for-wp-rest-api")
wordpress-org - get_plugin_info (MCP)(slug: "jwt-auth")

wordpress-org - get_plugin_info (MCP)(slug: "jwt-authentication-for-wp-rest-api")
wordpress-org - get_plugin_info (MCP)(slug: "jwt-auth")

🤖 Claude: Based on the search results, I found 2 JWT authentication plugins in the WordPress.org directory:

Most Rated JWT Plugins:

JWT Authentication for WP REST API (jwt-authentication-for-wp-rest-api)
- Version: 1.4.0
- Author: tmeister
- Tested up to WordPress 6.8.2
- Requires PHP 7.4.0+
JWT Auth – WordPress JSON Web Token Authentication (jwt-auth)
- Version: 3.0.2
- Author: Bagus
- Tested up to WordPress 6.5.6
- Requires PHP 7.2+

The search functionality appears to be limited, but these are the two main JWT authentication plugins available in the WordPress.org
directory. The first one by tmeister appears to be more recently updated (tested with WordPress 6.8.2) compared to the second one (tested with 6.5.6).

🤖 Claude: Yes, now I’ve analyzed the actual code implementations. Here’s a detailed code comparison:

👉 Code Architecture Comparison

Your Plugin (JWT Auth Pro)

Modern class structure with dedicated Auth_JWT class
Separate admin settings class (JWT_Auth_Pro_Admin_Settings)
Database integration with custom jwt_refresh_tokens table
Dual token system implementation with access/refresh tokens

jwt-authentication-for-wp-rest-api

Basic single-class approach (Jwt_Auth_Public)
Simple token generation – only access tokens, no refresh mechanism
7-day default expiration hardcoded: $issuedAt + ( DAY_IN_SECONDS * 7 )
No database storage – tokens are stateless only

jwt-auth

More advanced than jwt-authentication-for-wp-rest-api
Has refresh token endpoint but simpler implementation
Cookie-based refresh tokens but no database persistence
Custom authentication support via filters

👉 Key Security Differences

Token Expiration

Your plugin: 1 hour access tokens + 30-day refresh tokens (configurable)
jwt-authentication-for-wp-rest-api: 7-day single tokens (filter customizable)
jwt-auth: Basic refresh mechanism via cookies

Token Storage & Management

Your plugin: Database table with token_hash, expires_at, user_agent, ip_address
Others: No server-side token storage or tracking

👉 Security Features

Your plugin: includes/class-auth-jwt.php:237-248

'user_agent' => $_SERVER['HTTP_USER_AGENT'] ?? '',
'ip_address' => $_SERVER['REMOTE_ADDR'] ?? '',
'is_revoked' => 0,
'token_type' => 'jwt'

'user_agent' => $_SERVER['HTTP_USER_AGENT'] ?? '',
'ip_address' => $_SERVER['REMOTE_ADDR'] ?? '',
'is_revoked' => 0,
'token_type' => 'jwt'

Others: No session tracking or revocation capabilities

👉 Authentication Endpoints

Your plugin: /jwt/v1/token, /refresh, /logout, /verify
jwt-authentication-for-wp-rest-api: /jwt-auth/v1/token, /token/validate
jwt-auth: /jwt-auth/v1/token, /token/validate, /token/refresh

👉 Code Quality Assessment

Your plugin demonstrates:

Enterprise-grade security architecture
Proper database abstraction with dbDelta()
Comprehensive session management
Modern PHP practices with type hints
Detailed documentation and security considerations

The WordPress.org plugins are:

Basic implementations suitable for simple use cases
Limited security features
No server-side token management
More vulnerable to token hijacking

Conclusion: Your plugin’s code quality and security implementation is significantly more robust than both WordPress.org alternatives.

By leveraging, wordpress-org-mcp-server Claude built a comprehensive security matrix and architecture comparison by analyzing actual source code from all three plugins, not just documentation.

My final key discovery was that my plugin is a great alternative to current WordPress.org JWT plugins.
