+# 🤖 Base AI Agent Skills & MCP Studio
+
+An interactive **AI Agent Skills Sandbox**, **Base MCP Protocol Runner**, and **On-Chain Capability Inspector** for **Base Skills (`base/skills`)**.
+
+---
+
+## 🌟 Key Features
+
+- 🤖 **On-Chain Agentic Capabilities**: Equip AI agents (Claude, GPT, Cursor) with native Base skills to launch ERC-20 tokens, swap on Uniswap V3, and settle X402 micropayments.
+- ⚡ **Base MCP Server Protocol**: Native Model Context Protocol interface for wallet actions (`mcp.base.org`).
+- 🌐 **Interactive Web Studio**: Live Agent Skills sandbox and execution payload inspector on `http://localhost:3426`.
+- ⌨️ **Universal CLI (`base-skills-cli`)**: Terminal utility for listing and executing Base agent skills.
+
+---
+
+## 🚀 Quickstart
+
+```bash
+# Launch Base Skills Studio
+npm start
+# Open http://localhost:3426
+
+# Or run via CLI
+node bin/base-skills-cli.js list
+node bin/base-skills-cli.js run erc20_token_launcher
+```
