TypeScript MCP Server Generator

An AI skill that generates TypeScript based Model Context Protocol servers, scaffolding complete projects with type safe tool definitions, Zod schema validation, async handlers, and transport configuration for building reliable MCP integrations.

What Is This?

Overview

This skill creates complete TypeScript MCP server projects from a description of the tools and resources you want to expose. It generates the project structure with package.json, tsconfig, tool handler files with Zod input validation, transport setup for stdio and HTTP, and comprehensive type definitions. The generated code uses TypeScript strict mode throughout, catching protocol errors at compile time and providing excellent IDE support.

Who Should Use This

Ideal for TypeScript developers building AI tool integrations, teams with existing Node.js backends wanting MCP interfaces, and developers who value type safety in protocol implementations. TypeScript has the most mature MCP ecosystem, making this the recommended starting point for most projects.

Why Use It?

Problems It Solves

Setting up an MCP server requires implementing JSON-RPC message handling, tool registration, schema validation, and transport protocols. Even in TypeScript with good library support, the boilerplate for a well structured server with proper types, validation, and error handling takes significant time. This skill generates everything needed to start building tools immediately.

Core Highlights

• Full Project Scaffold generates package.json, tsconfig, and complete source structure
• Zod Validation creates runtime schema validation for all tool inputs
• Type Inference derives TypeScript types from Zod schemas automatically
• Transport Ready configures both stdio and streamable HTTP transports
• Error Handling implements typed error responses following MCP specification

How to Use It?

Basic Usage

Describe your tools and receive a complete TypeScript MCP server project.

// Generated: src/tools/search.ts
import { z } from "zod";
import { defineTool } from "../framework/tool.js";

export const searchTool = defineTool({
  name: "search_docs",
  description: "Search documentation by keyword",
  inputSchema: z.object({
    query: z.string().describe("Search query"),
    limit: z.number().default(10).describe("Max results"),
  }),
  handler: async (input) => {
    // input is fully typed as { query: string; limit: number }
    const results = await searchIndex(input.query, input.limit);
    return { results, total: results.length };
  },
});

Real-World Examples

Database Query Tool Server

A team generated an MCP server that exposed their PostgreSQL database as AI accessible tools. The server included tools for running read only queries, listing tables, describing schemas, and explaining query plans, all with proper input validation and connection pooling.

// Generated: src/server.ts
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { searchTool } from "./tools/search.js";
import { queryTool } from "./tools/query.js";
import { schemaTool } from "./tools/schema.js";

const server = new McpServer({ name: "db-tools", version: "1.0.0" });

server.tool(queryTool.name, queryTool.inputSchema, queryTool.handler);
server.tool(searchTool.name, searchTool.inputSchema, searchTool.handler);
server.tool(schemaTool.name, schemaTool.inputSchema, schemaTool.handler);

const transport = new StdioServerTransport();
await server.connect(transport);

Advanced Tips

Use TypeScript project references to organize large servers into separate tool packages. Leverage Zod's transform methods to coerce and normalize input data before it reaches your handler. Add middleware functions for logging, rate limiting, and authentication.

When to Use It?

Use Cases

• API Integration expose existing REST APIs as MCP tools for AI assistants
• Database Access provide structured database query tools with safety guardrails
• DevOps Tooling wrap deployment and monitoring commands as MCP services
• Content Management expose CMS operations through type safe MCP tools
• Development Utilities share code analysis and generation tools via MCP

Important Notes

Requirements

• Node.js 18 or later for full ES module and async support
• TypeScript 5.0 or later with strict mode enabled
• An MCP compatible client for testing the generated server
• npm or pnpm for dependency management

Usage Recommendations

Do:

• Keep Zod schemas as the source of truth for both validation and type definitions
• Write integration tests that exercise the full request and response cycle
• Use environment variables for sensitive configuration like database credentials
• Enable strict TypeScript to catch type errors during development

Don't:

• Use any types in tool handlers as this defeats the purpose of TypeScript
• Skip Zod validation relying only on TypeScript compile time checks
• Expose write operations without proper authorization middleware
• Ignore unhandled promise rejections as they crash the server process

Limitations

• Generated servers need manual integration with existing application code
• Complex tool interactions requiring shared state need custom implementation
• Large response payloads may hit MCP client context limits
• Hot reloading during development requires additional tooling setup
