SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

The mcp-builder Skill simplifies the creation and configuration of Model Context Protocol (MCP) servers from a capability specification, streamlining the process for Kiro and other MCP clients to interact with APIs, databases, or local capabilities.

Core Features & Use Cases

  • Server Scaffold: Automatically generates the structure for MCP servers based on a capability spec.
  • Transport Selection: Allows selection between stdio and HTTP transport for server interaction.
  • Resource Definition: Facilitates the definition of tools, resources, and prompts for the server.
  • Validation & Registration: Validates inputs and registers the server with Kiro, ensuring it's ready for use.
  • Use Case: Ideal for users who need to expose an internal API, debug an MCP server, or decide on the transport method for a new server.

Quick Start

Build and register an MCP server for a weather API with stdio transport using the mcp-builder skill.

FAQPage Schema
How do I build an MCP server from a capability specification?▼

Building an MCP server from a capability specification involves automating the construction and registration process. The system generates the server scaffold, defines tools and resources, and registers the server for Kiro and other MCP clients.

What transport options are available when creating an MCP server?▼

When creating an MCP server, you can select between stdio and HTTP transport options. This choice determines how Kiro and other MCP clients interact with the exposed APIs, databases, or local capabilities.

How does MCP server configuration management work with Kiro clients?▼

MCP server configuration management with Kiro clients works by validating inputs and registering the server directly. This ensures the defined tools, resources, and prompts are ready for client interaction.

Do I need environment variables for MCP protocol development?▼

Yes, you need environment variables for MCP protocol development to manage credentials and configuration. This is required to securely expose internal APIs or local capabilities to Kiro and other MCP clients.

Can I expose an internal API as a resource for an MCP client?▼

Yes, you can expose an internal API as a resource for an MCP client. The server building process facilitates the definition of tools, resources, and prompts from your capability specification.

What is the best way to register a local capability with an MCP server?▼

The best way to register a local capability with an MCP server is by using an automated builder to validate inputs and register the configuration. This ensures the server is hardened and ready for Kiro clients.
