AcrossAI MCP Manager

MCP Manager uses the standard @automattic/mcp-wordpress-remote@latest package with WordPress Application Passwords for the default remote flow. It also includes an optional experimental direct Claude Connectors mode backed by a WordPress-hosted OAuth approval flow.

MCP Manager is a WordPress plugin that enables seamless integration with Model Context Protocol (MCP) servers, allowing AI assistants and code editors to safely access your WordPress instance through secure application passwords.

Key Features

• Multi-Client Support: Configure MCP for:

  • VS Code with Copilot
  • Claude Desktop App
  • GitHub Copilot & Codex
  • OpenAI ChatGPT Codex
  • Custom MCP Clients

• Secure Authentication: Uses WordPress native Application Passwords system

  • One-click password generation
  • Secure credential management
  • Password revocation support
  • Per-server Access Control still enforced after authentication

• Easy Configuration:

  • Copy-paste ready JSON configurations
  • Per-provider configuration file paths
  • Automatic top-level key detection

• Format #1 Standard: Uses the Automattic-recommended MCP configuration format

  • npx command execution
  • @automattic/mcp-wordpress-remote@latest package
  • Full environment variable support

How It Works

1. Navigate to Settings → MCP Manager
2. Select your MCP client (VS Code, Claude, GitHub Copilot, ChatGPT, or Custom)
3. Click “Generate New Application Password”
4. Copy the ready-to-use JSON configuration
5. Paste into your client’s configuration file
6. Restart your MCP client

All application passwords are managed through WordPress’s native Application Passwords system and appear in your profile under Account Management.

CLI Connection and Authorization Flow

MCP Manager also supports a browser-assisted CLI connection flow for local MCP clients.

Typical command:

Flow summary:

1. The CLI checks /wp-json/acrossai-mcp-manager/v1/health
2. The CLI starts auth with /wp-json/acrossai-mcp-manager/v1/auth/start
3. WordPress returns an auth_code and frontend auth_url
4. The CLI opens the frontend approval page at /acrossai-mcp-manager/
5. If needed, the user signs in through normal WordPress login
6. The signed-in user approves access in the browser
7. The CLI polls /auth/status until the request is approved
8. The CLI fetches the approved user’s accessible servers from /servers
9. The CLI exchanges the approved code at /auth/exchange
10. WordPress creates a one-time Application Password and the CLI writes the MCP client config

Terminology:

• Sign in / Log in = WordPress account authentication
• Connect = starting the CLI-to-site linking flow
• Authorize / Approve access = granting the CLI permission in the browser

Important notes:

• The frontend authorization page must never be cached
• Auth codes are single-use
• /servers and /auth/exchange respect per-server access control
• User-facing copy should say CLI Connections rather than npm Login
• Generated remote MCP configs use Application Passwords and explicitly disable OAuth discovery in @automattic/mcp-wordpress-remote

Experimental Direct Claude Connectors

An optional Claude Connectors Screen (Experimental) setting can enable a direct OAuth flow for Claude’s hosted connectors.

When the global feature toggle is enabled and a specific server is configured in its Claude Connector tab, the plugin exposes:

• /.well-known/oauth-authorization-server
• /.well-known/oauth-protected-resource?resource=<mcp-url>
• /acrossai-mcp-connectors/oauth/authorize/
• /wp-json/acrossai-mcp-manager/v1/connector/oauth/token

Important notes:

• Disabled by default
• The Application Password flow remains available and supported
• The master experimental toggle is global, but OAuth client settings are stored per server
• Direct connector approval signs Claude in as a WordPress user
• Per-server Access Control still applies to every MCP request after OAuth
• Public HTTPS is recommended for hosted connector usage

Provider Configuration Paths

• VS Code: ~/.config/Code/User/globalStorage/Copilot.copilot-chat/mcp.json (top-level key: “servers”)
• Claude: ~/Library/Application Support/Claude/claude_desktop_config.json (top-level key: “mcpServers”)
• GitHub Copilot: ~/.gh-copilot/config.json (top-level key: “servers”)
• OpenAI ChatGPT: ~/.config/chatgpt/config.json (top-level key: “servers”)
• Custom: ./your-project/.mcp/config.json (top-level key: configurable)

Requirements

• WordPress 5.9 or higher
• PHP 8.0 or higher
