### Prefixing Strategy
Tools from each server are prefixed with the user-provided server name to avoid conflicts:
The implementation normalizes the server name and uses `__` as the separator so
prefixed tool names stay within provider tool-name constraints that disallow dots.

```typescript
// Original tool from weather server: "get_weather"
// Prefixed tool: "weather_server.get_weather"
// Prefixed tool: "weather_server__get_weather"

// Original tool from calendar server: "get_events"
// Prefixed tool: "calendar.get_events"
// Prefixed tool: "calendar__get_events"
```

### Tool Discovery and Registration
```typescript
class MCPConnection {
private async discoverTools(): Promise<Tool[]> {
const tools = await this.client.listTools();
const normalizedServerName = normalizeServerName(this.name);
return tools.map(tool => ({
...tool,
function: {
...tool.function,
name: `${this.name}.${tool.function.name}`, // Add prefix
name: `${normalizedServerName}__${tool.function.name}`, // Add prefix
description: `[${this.name}] ${tool.function.description}`, // Add server context
}
}));
