Template MCP
A TypeScript MCP server template with Zod validation, dual transport (stdio/HTTP), and modular architecture for building MCP-compatible tools, resources, and prompts.
What is Template MCP?
Template MCP is a Model Context Protocol (MCP) server that allows AI assistants like Claude, Cursor, and VS Code to typescript mcp server template with zod validation, dual transport (stdio/http), and modular architecture for building mcp-compatible tools, resources, and prompts.
A TypeScript MCP server template with Zod validation, dual transport (stdio/HTTP), and modular architecture for building MCP-compatible tools, resources, and prompts.
This server falls under the Developer Tools category on MCPgee, the world's largest MCP server directory with 33,000+ servers.

How to Set Up and Use Template MCP
template-mcp is a production-ready TypeScript starter kit for building Model Context Protocol servers from scratch, providing everything needed to scaffold a new MCP server in minutes rather than hours. It ships with dual transport support (stdio for local clients and Streamable HTTP for remote clients), strict TypeScript with ESM modules, Zod for tool input validation, Joi for environment variable validation at startup, Pino for stderr-safe logging, and a full test suite using Vitest with the MCP SDK in-memory transport. It is intended as a fork-and-extend template rather than a running server — developers clone it and add their own tools, resources, and prompts following the modular architecture.
Prerequisites
- Node.js 22 or higher
- pnpm package manager installed (npm install -g pnpm)
- Git to clone the repository
- An MCP-compatible client for testing (Claude Desktop, Claude Code, Cursor, VS Code Copilot)
Clone the template repository
Fork or clone the template-mcp repository to start your new MCP server project. This gives you the full project structure with all tooling pre-configured.
git clone https://github.com/Freddymhs/template-mcp my-mcp-server
cd my-mcp-serverInstall dependencies
Install all project dependencies using pnpm. The project uses pnpm workspaces and lockfile for reproducible installs.
pnpm installConfigure environment variables
Copy the example environment file to .env and adjust the transport type, port (for HTTP mode), log level, and Node.js environment as needed.
cp .env.example .env
# Edit .env:
# MCP_TRANSPORT=stdio # or 'http' for remote clients
# PORT=3000
# LOG_LEVEL=info
# NODE_ENV=developmentAdd your own tools to the server
Create a new tool file under src/tools/ following the existing pattern with Zod input schema, then register it in src/tools/index.ts. Each tool is a self-contained module.
# Example: src/tools/my-tool.tool.ts
# Then in src/tools/index.ts:
# import { registerMyTool } from './my-tool.tool.js';
# registerMyTool(server);Build and configure your MCP client
Compile the TypeScript source and point your MCP client at the compiled output. Use the absolute path to dist/main.js in the client config.
pnpm buildRun tests to verify everything works
The template includes a full Vitest test suite with MCP SDK in-memory transport for testing tools without a live client. Run tests after adding new tools.

}
}Prompts to try
The template ships with a greet example tool. After adding your own tools, prompts will match your implementation.
- "Use the greet tool to say hello to Alice."
- "What tools are available in the template-mcp server?"
- "Call my_tool with param set to 'test value'."
- "List all MCP resources exposed by this server."Troubleshooting Template MCP
pnpm build fails with TypeScript errors
Run pnpm type-check to see detailed errors. The template uses strict TypeScript so all types must be explicit. Ensure you are on Node.js 22+ and that pnpm install completed without errors before building.
MCP client cannot find the server after build
Use an absolute path to dist/main.js in the client config, not a relative path. Confirm the build succeeded and dist/main.js exists. If using HTTP transport (MCP_TRANSPORT=http), ensure the PORT is reachable and not blocked by a firewall.
Env validation fails at startup with Joi error
The template uses Joi to validate environment variables at startup and will exit immediately if required vars are missing or invalid. Check your .env file against .env.example and ensure MCP_TRANSPORT is set to either 'stdio' or 'http'.
