Frequently asked questions
AI-generated answers based on this skill's SKILL.md and metadata
How do I build a MCP server for Claude?
MCP Server Builder guides you through creating a Model Context Protocol server that extends Claude with custom capabilities. Start by setting up a TypeScript project, define your server's purpose, choose a transport layer (stdio for Claude Desktop or HTTP with SSE for API), and implement request handlers. The skill covers tool schema definition, resource management, and deployment configuration for seamless Claude integration.
What transport options does MCP Server Builder support?
MCP Server Builder covers two main transport layers: stdio transport for Claude Desktop integration, which runs your server as a local subprocess, and HTTP with Server-Sent Events (SSE) for API deployment. Each transport has distinct setup patterns and configuration requirements. The skill walks through both architectures so you can choose based on your deployment target and integration needs.
How do I create custom Claude tools with MCP?
MCP Server Builder teaches you to define tools by creating schemas that specify tool names, descriptions, and input parameters with validation. You implement tool handlers that process requests and return results. The skill covers the complete pattern: schema definition, request handler implementation, error handling best practices, and integration with Claude's tool-calling system for reliable custom functionality.
Can MCP Server Builder help set up resources and prompts?
Yes, MCP Server Builder includes guidance on adding optional resources and prompts to your server beyond tools. Resources let you expose data or files, while prompts provide reusable instruction templates. The skill demonstrates setup patterns for both, showing how to structure them alongside your tools for a complete Model Context Protocol implementation.
How do I test and validate my MCP server?
MCP Server Builder covers testing your server implementation using the MCP inspector, which lets you validate that your tools, resources, and prompts work correctly before deploying to Claude. The skill includes validation patterns and error handling best practices to ensure your server behaves reliably when integrated with Claude Desktop or the API.
What's the best way to configure MCP servers for Claude Desktop?
MCP Server Builder walks through Claude Desktop configuration by setting up stdio transport, defining your server executable path, and testing the connection. The skill covers the full integration workflow: project structure, TypeScript compilation, transport setup, and Desktop configuration steps so your custom tools appear in Claude immediately.

MCP Server Builder
Create Model Context Protocol servers to extend Claude's capabilities with custom tools and resources.
Core Workflow
- Define purpose: Identify what capabilities to add
- Choose transport: stdio (local) or HTTP/SSE (remote)
- Design tools: Define tool schemas and handlers
- Add resources: Optional file/data access
- Create prompts: Optional reusable prompts
- Test locally: Verify with MCP inspector
- Deploy: Configure for Claude Desktop or API
