How to Set Up and Use Tmcp
tmcp is a TypeScript SDK for building Model Context Protocol (MCP) servers in a transport-agnostic way. It supports multiple schema validation adapters (Zod, Valibot, ArkType, Effect) and multiple transport mechanisms including stdio and HTTP, letting developers choose their preferred tooling. Developers use tmcp when they want a clean, type-safe API for registering tools, prompts, resources, and URI templates with their MCP server without being locked into a single transport or validation library.
Prerequisites
- Node.js 18+ or Bun runtime
- pnpm, npm, or yarn package manager
- An MCP client such as Claude Desktop or Claude Code
- A schema validation library (e.g. Zod) if using typed tool schemas
Install tmcp and a transport adapter
Install the core tmcp package along with the stdio transport adapter to start building a server that communicates over standard input/output.
pnpm install tmcp @tmcp/transport-stdioInstall a schema validation adapter (optional but recommended)
Choose and install one of the supported adapters for type-safe tool parameter validation. Zod is the most popular choice.
pnpm install @tmcp/adapter-zod zodCreate your MCP server file
Create a server entry point that initializes the McpServer with your chosen adapter and registers tools, prompts, or resources.
import { McpServer } from 'tmcp';
import { ZodAdapter } from '@tmcp/adapter-zod';
import { z } from 'zod';
const server = new McpServer(
{ name: 'my-server', version: '1.0.0', description: 'My MCP server' },
{ adapter: new ZodAdapter() }
);
server.tool({
name: 'greet',
description: 'Greet a user by name',
schema: z.object({ name: z.string() })
}, async ({ name }) => ({
content: [{ type: 'text', text: `Hello, ${name}!` }]
}));Attach the stdio transport and start listening
Connect the StdioTransport to your server instance to handle MCP communication over stdin/stdout, which is how Claude Desktop spawns MCP servers.
import { StdioTransport } from '@tmcp/transport-stdio';
new StdioTransport(server).listen();Configure Claude Desktop to use your server
Add an entry to your Claude Desktop configuration file pointing to your compiled server script.
{
"mcpServers": {
"my-tmcp-server": {
"command": "node",
"args": ["/path/to/your/server.js"]
}
}

Client configuration
Claude Desktop config for a tmcp-based server running via Node.js
{
"mcpServers": {
"my-tmcp-server": {
"command": "node",
"args": ["/absolute/path/to/dist/server.js"]
}
}
}Prompts to try
Once your tmcp server is running and connected, try these prompts to exercise registered tools
- "Greet me by name using the greet tool"
- "List all available tools on this server"
- "Call the calculate tool with operation add, a=5, b=3"Troubleshooting Tmcp
Server fails to start with 'Cannot find module' errors
Ensure you have run `pnpm install` in your project directory and that all tmcp packages (including the chosen transport and adapter) are listed in package.json dependencies.
Claude Desktop does not discover the server tools
Verify the absolute path in claude_desktop_config.json points to the compiled JS output. Rebuild your TypeScript project with `tsc` before restarting Claude Desktop.
Schema validation errors when calling tools
Make sure the installed adapter version matches your validation library version. For Zod, use `@tmcp/adapter-zod` paired with Zod v3 or `@tmcp/adapter-zod-v3` if on an older version.
