Provides example implementations and source code through GitHub repositories.
Available as an npm package for easy installation in Node.js projects.
Provides full TypeScript integration with type safety for creating MCP servers.
Implements built-in parameter validation using Zod schemas for MCP tools.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@MCPKitcreate a greeting tool that accepts a name parameter"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Simple MCP
A simple TypeScript library for creating MCP (Model Context Protocol) servers.
Features
Simple API: Create MCP servers with minimal code
Type Safety: Full TypeScript integration
Parameter Validation: Built-in validation with Zod
MCP Compatible: Fully implements the Model Context Protocol
Related MCP server: MCP Server Starter
Installation
npm install simple-mcpQuickstart
import { McpServer } from 'simple-mcp';
import { z } from 'zod';
// Create a server instance
const server = new McpServer({ name: 'my-server' });
// Register the tool with the server
server.tool({
name: 'greet',
parameters: {
name: z.string().describe('Person\'s name')
},
execute: async ({ name }) => {
return {
content: [
{
type: 'text',
text: `Hello, ${name}! Nice to meet you.`
}
]
};
}
});
// Start the server
server.start({ transportType: 'stdio' });Class-based Implementation
You can also implement MCP tools using classes:
import { McpServer, type McpTool } from 'simple-mcp';
import { z, ZodObject } from 'zod';
const parameters = {
name: z.string().describe('The name is required'),
};
class GreetTool implements McpTool<typeof parameters> {
public readonly name = 'greet';
public readonly parameters = parameters;
public async execute({ name }: z.infer<ZodObject<typeof this.parameters>>) {
return {
content: [
{
type: 'text',
text: `Hello, ${name}! Nice to meet you.`,
},
],
};
}
}
// Initialize a new MCP server with the name 'greet-server'
const server = new McpServer({ name: 'greet-server' });
// Create an instance of the GreetTool class
const greetTool = new GreetTool();
// Register the tool with the server
server.tool(greetTool);
// Start the server using stdio as the transport method
server.start({ transportType: 'stdio' });Examples
