The Role of MCP in Modern AI Development
MCP acts as a universal translator between AI models and tools. When an AI model needs to perform a specific task - whether it's analyzing an image, querying a database, or making an API call - MCP provides the structured format for this interaction. This standardization brings several key benefits to modern AI development.
Simplified Integration
Enhanced Scalability
Key Features
- •Tool definitions with clear interfaces
- •Parameter validation and type safety
- •Error handling and responses
- •API endpoint structure
Implementation Example: Weather Tool
// Basic MCP Tool Interface
interface MCPTool {
name: string;
description: string;
parameters: { type: "object"; properties: Record<string, unknown>; required: string[] };
execute: (params: Record<string, unknown>) => Promise<unknown>;
}
// Example Weather Tool Implementation
const weatherTool: MCPTool = {
name: "getWeather",
description: "Get current weather for a location",
parameters: {
type: "object",
properties: {
location: { type: "string", description: "The city or ZIP code to get weather for" },
},
required: ["location"],
},
execute: async (params: Record<string, unknown>) => {
const { location } = params as { location: string };
const mockWeatherData = {
location,
temperature: Math.floor(Math.random() * 30) + 10,
condition: ["Sunny", "Cloudy", "Rainy"][Math.floor(Math.random() * 3)],
timestamp: new Date().toISOString(),
};
return mockWeatherData;
},
};
// Example Usage
async function callMCPTool(tool: MCPTool, input: Record<string, unknown>) {
try { return await tool.execute(input); } catch (error) { throw new Error("Failed to execute MCP tool"); }
}
