Using "mcp-apps-builder". How do I structure my MCP server?
Expected outcome:
- A basic MCP server structure includes:
- 1. Server initialization with required capabilities
- 2. Tool definitions and handlers
- 3. Resource providers if needed
- 4. Prompt templates for reusable prompts
- 5. Widget definitions for interactive UIs
Using "mcp-apps-builder". What authentication options exist?
Expected outcome:
- Supported authentication providers:
- - Custom authentication (bring your own auth)
- - Supabase authentication
- - WorkOS authentication
- Each provider has specific configuration requirements documented in the references/authentication/ directory.
Using "mcp-apps-builder". How do I handle errors in my MCP server?
Expected outcome:
- Error handling best practices:
- 1. Use response helpers for structured errors
- 2. Return appropriate error codes
- 3. Log errors for debugging
- 4. Handle exceptions gracefully to prevent server crashes

What You Can Build
New MCP Server Development
Developers starting a new MCP server project consult this skill for architecture guidance, authentication setup, and deployment best practices before writing code.
Debugging MCP Issues
When encountering problems with existing MCP servers, developers reference this skill to identify common pitfalls and verify their implementation matches recommended patterns.
Learning MCP Concepts
Engineers learning about Model Context Protocol use this skill to understand core concepts like tools, resources, prompts, and how they integrate with the mcp-use framework.
Try These Prompts
Help me create a basic MCP server using the mcp-use framework. What are the essential files and structure I need?
I need to add authentication to my MCP server. What authentication providers are supported and how do I configure them?
Show me how to register custom tools in my MCP server. What is the correct pattern for tool definitions and handlers?
What are the best practices for deploying an MCP server to production? Include environment configuration and security considerations.
Best Practices
- Always validate input parameters in tool handlers before processing
- Use environment variables for sensitive configuration, never hardcode credentials
- Register tools, resources, and prompts during server initialization for proper capability advertisement
- Test MCP server locally using the MCP inspector before deployment
Avoid
- Do not hardcode API keys or secrets in source code - use environment variables
- Avoid blocking operations in tool handlers - use async patterns for I/O operations
- Do not skip error handling - unhandled exceptions can crash the MCP server
