/claude-desktop-extension

I want to build this as a Desktop Extension, abbreviated as "DXT". Please follow these steps:

1. Read the specifications thoroughly:

   • https://github.com/anthropics/dxt/blob/main/README.md - DXT architecture overview, capabilities, and integration patterns
   • https://github.com/anthropics/dxt/blob/main/MANIFEST.md - Complete extension manifest structure and field definitions
   • https://github.com/anthropics/dxt/tree/main/examples - Reference implementations including a "Hello World" example

2. Create a proper extension structure:

   • Generate a valid manifest.json following the MANIFEST.md spec
   • Implement an MCP server using @modelcontextprotocol/sdk with proper tool definitions
   • Include proper error handling and timeout management

3. Follow best development practices:

   • Implement proper MCP protocol communication via stdio transport
   • Structure tools with clear schemas, validation, and consistent JSON responses
   • Make use of the fact that this extension will be running locally
   • Add appropriate logging and debugging capabilities
   • Include proper documentation and setup instructions

4. Test considerations:

   • Validate that all tool calls return properly structured responses
   • Verify manifest loads correctly and host integration works

Generate complete, production-ready code that can be immediately tested. Focus on defensive programming, clear error messages, and following the exact DXT specifications to ensure compatibility with the ecosystem.
