# MCPB Packaging Skill (DXT legacy) Guidelines for building and packaging MCP servers as MCP Bundles (MCPB). DXT references are legacy. ## Overview MCP Bundles (MCPB) allow AI assistants to discover and use MCP servers from a package archive. This skill covers the complete MCPB development workflow. ## Getting Started ### Read the Specifications 1. **Architecture & Overview**: https://github.com/anthropics/mcpb 2. **MCPB Repository**: https://github.com/anthropics/mcpb - `README.md` - Architecture overview, capabilities, and integration patterns - `MANIFEST.md` - Complete bundle manifest structure and field definitions - `examples/` - Reference implementations including a "Hello World" example ### Create Proper Bundle 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 ## Development Best Practices ### MCP Protocol Communication - 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 bundle will be running locally ### Logging & Debugging - Add appropriate logging and debugging capabilities - Use structured logging for error tracking - Include proper documentation and setup instructions ### Testing 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 and clear error messages - Follow the exact MCPB specifications to ensure ecosystem compatibility ## Key Files - **manifest.json** - Bundle metadata and configuration - **src/index.ts** - Main entry point for the MCP server - **build/** - Compiled output for distribution ## References - [MCPB GitHub Repository](https://github.com/anthropics/mcpb) - [MCP TypeScript SDK](https://github.com/modelcontextprotocol/typescript-sdk)
