SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide for using the MCPKit Swift package to build MCP (Model Context Protocol) tool servers, helping developers quickly set up tool servers, define tools, and integrate MCP into Swift projects.

Core Features & Use Cases

  • Architecture & Setup: Understand MCPKit's Core/Transport structure and how to wire a server.
  • Quick Start Guidance: Step-by-step to define a tool, implement a context, register tools, and run a server.
  • JSON-RPC & Tools API: Learn how to list tools, call tools, and interact via JSON-RPC.

Quick Start

Create a new MCP tool by implementing MCPTool, wire it with a context, register the tool with the registry, and start MCPHTTPServer on a chosen port, then call the tool via JSON-RPC.

FAQPage Schema
How do I build an MCP tool server with MCPKit in Swift?▼

MCPKit is a Swift package for building MCP tool servers. Implement MCPTool with your tool logic, create an MCPContext, register tools with MCPRegistry, and start MCPHTTPServer on your chosen port to enable JSON-RPC communication.

What's required to define and register a tool in MCPKit?▼

Define a tool by implementing the MCPTool protocol, specify its schema with MCPInputSchema, configure it within an MCPContext, and register it with the tool registry. MCPHTTPServer then exposes it via JSON-RPC endpoints.

Can I use MCPKit to set up HTTP-based JSON-RPC communication?▼

Yes. MCPKit separates Core logic from Transport layer. MCPHTTPServer handles JSON-RPC communication over HTTP, allowing clients to list and call registered tools remotely without managing protocol details yourself.

Do I need prior MCP experience to use MCPKit?▼

No. MCPKit provides quick-start guidance covering tool definition, context setup, and server deployment. The guide walks through each step from creating your first tool to running a live server.

What does MCPKit's Core and Transport architecture mean for my setup?▼

MCPKit separates Core (tool logic, schemas, registry) from Transport (HTTP, JSON-RPC protocol handling). This split lets you define tools once and swap communication layers, simplifying both development and deployment flexibility.

How do I call a tool once my MCPKit server is running?▼

Send a JSON-RPC request to your MCPHTTPServer endpoint with the tool name and input parameters. MCPKit deserializes the request, invokes the registered tool, and returns the result as a JSON-RPC response.
