What Happened?

On March 31, 2026, Anthropic accidentally exposed the full internal source code of Claude Code — its AI-powered coding assistant — through a massive 59.8 MB JavaScript source map (.map) file that was bundled inside the public npm package @anthropic-ai/claude-code version 2.1.88.

The source map file pointed to a zip archive hosted on Anthropic’s own Cloudflare R2 cloud storage, containing nearly 2,000 files and 500,000 lines of code — the entire internal codebase of Claude Code.

How Was It Discovered?

The leak was discovered by Chaofan Shou (@Fried_rice), an intern at Solayer Labs, who posted about it on X (formerly Twitter) with a direct download link. Within hours, the codebase was:

• Downloaded directly from Anthropic’s Cloudflare R2 bucket
• Mirrored to GitHub repositories
• Forked tens of thousands of times by the developer community

Root Cause: A Bun Bug

The leak was caused by a known bug in Bun (issue #28001, filed March 11, 2026) where source maps are incorrectly served in production builds even when disabled in configuration. The bug had been open for 20 days before the incident. A debugging file was accidentally bundled into a routine Claude Code update and pushed to the public npm registry.

What Was Inside the Leaked Code?

The exposed source code revealed several undisclosed features that appear fully built but not yet publicly released:

• Session memory: Claude reviewing its own previous sessions to improve future performance and transfer learnings across conversations
• Persistent background mode: Claude Code continuing to work autonomously even when the user is idle
• Remote control: Ability to control Claude Code from a phone or another browser
• Frustration tracking: Telemetry that monitors and logs user frustration signals

Anthropic’s Official Response

“Earlier today, a Claude Code release included some internal source code. No sensitive customer data or credentials were involved or exposed. This was a release packaging issue caused by human error, not a security breach. We’re rolling out measures to prevent this from happening again.”

— Anthropic Spokesperson (via Axios)

Security Implications

While Anthropic confirmed no customer data or credentials were exposed, security researchers have noted that revealing internal architecture, feature flags, and implementation details gives competitors and potential attackers a detailed playbook of Claude Code’s internals. Analysts at IANS Research described it as exposing “safety gaps” that could be exploited by rivals.

The Model Context Protocol (MCP) is an open standard introduced by Anthropic that allows AI assistants like Claude to securely interact with external systems, APIs, and data sources. By installing the WordPress MCP plugin, you create a direct, two-way bridge between Claude and your WordPress site — enabling AI-powered content management, automation, and more.

⚙️ How the Connection Works

Step-by-Step Architecture

1. Install WordPress MCP Plugin — Add the WordPress MCP plugin to your site. It registers a secure REST endpoint that Claude can communicate with.
2. Configure Claude Code or Claude Desktop — Add the MCP server configuration pointing to your WordPress site’s MCP endpoint with your application password credentials.
3. Claude Discovers Tools — On connection, Claude reads the available tools (create post, get media, update settings, etc.) and resources (posts list, site info) exposed by the plugin.
4. Natural Language Commands — You instruct Claude in plain English: “Create a post about our new product launch” and Claude translates that into the appropriate REST API calls.
5. Results Flow Back — WordPress executes the action and returns structured data to Claude, which then summarizes or confirms the result for you.

📋 Claude Code MCP Configuration

To connect Claude Code CLI to your WordPress site, add the following MCP server configuration to your ~/.claude/settings.json or project-level .claude/settings.json:

{
  "mcpServers": {
    "wordpress": {
      "command": "node",
      "args": ["/path/to/wordpress-mcp/server.js"],
      "env": {
        "WORDPRESS_URL": "https://yoursite.com",
        "WORDPRESS_USERNAME": "your-username",
        "WORDPRESS_APP_PASSWORD": "xxxx xxxx xxxx xxxx xxxx xxxx"
      }
    }
  }
}

✨ What You Can Do with Claude + WordPress MCP

---

🛡️ Security & Authentication

The WordPress MCP plugin uses WordPress Application Passwords for authentication — a secure, token-based mechanism built into WordPress core since version 5.6. Each connection uses a unique application password that can be revoked at any time from your WordPress dashboard under Users → Your Profile → Application Passwords.

MCP transforms Claude from a standalone AI assistant into a collaborative partner that can take real action inside your WordPress site — safely, securely, and on your terms.

Doston, aaj hum baat karenge ek aisi technology ki jo WordPress ki duniya mein ek naya revolution laa rahi hai — WordPress MCP Plugin, yaani Model Context Protocol. Agar aap ek Indian developer, blogger, ya website owner hain, toh yeh guide sirf aapke liye likhi gayi hai! 🇮🇳

📌 MCP Kya Hota Hai? (Seedha Simple Bhasha Mein)

Socho aapke paas ek bahut hi intelligent naukar hai — jaise Claude ya ChatGPT. Lekin problem yeh hai ki woh directly aapki website ko dekh ya badal nahin sakta. Toh MCP ek “bridge” ki tarah kaam karta hai jo AI ko aapki WordPress site se seedha connect karta hai.

“MCP ek open protocol hai jo standardize karta hai ki applications LLMs (Large Language Models) ko context kaise provide karein.”

— Model Context Protocol Official Documentation

Matlab yeh ki aap apne AI assistant se seedha keh sakte hain: “Meri site par kal ki post publish kar do” — aur woh kar dega! Bina copy-paste ke, bina manual kaam ke. 🚀

🧠 MCP ke Teen Main Components

MCP protocol teen main cheezein provide karta hai jo AI ko WordPress ke saath kaam karne mein madad karti hain:

🔐 Security: Aapka Data Safe Rahega?

Yeh ek bahut important sawaal hai — khaaskar Indian users ke liye jo data privacy ko lekar concerned rehte hain. Good news yeh hai ki WordPress MCP architecture mein data tab share hota hai jab aap explicitly request karte hain. MCP server kisi bhi AI model ke saath tab tak data share nahin karta jab tak aap khud nahin chahte.

Aur MCP tools ka data AI models ko train karne ke liye kabhi use nahin hota — yeh data sirf ek baar original request ke part ke roop mein use hota hai. Matlab aapka website data secure hai. ✅
