Setup
Install MCP Server Starter Demo in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/abanoub-rodolf/mcp-server-starter-demo
Follow the installation instructions in the repository README, then restart your MCP client.
A free, deliberately small TypeScript MCP server fromThynkQ. It uses the current official SDK, runs over stdio, validates every input with Zod, and exposes two pure in-memory tools:
- echo: returns validated text unchanged;
- text_stats: counts words and characters.
It does not read files, call the network, spawn subprocesses, or accept secrets.
Build first, then copyconfigs/claude-desktop.example.jsonand replace the placeholder with the absolute path todist/index.js.
This is a public teaching demo, not the paid production starter. It intentionally omits:
- streamable HTTP transport;
- bearer authentication and constant-time comparison;
- rate limiting and DNS rebinding protection;
- structured redacted logging;
- typed safe error handling;
- the 72-test transport and security suite;
- three production client configurations and saved scan proof.
Those hardening layers are part ofMCP Server Starter Pro, which is in final storefront preparation. FollowThynkQ's MCP workfor the release.

Before connecting a third-party MCP server, run the freeMCP Security Review Preview. It is a limited Claude Code preflight that keeps raw scanner evidence outside model-facing output.
Also free: themcp-scansecurity scanner, and theMCP Security Evidence Redactorfor safe severity-count summaries of scan output.
The client launches this process and communicates over stdin/stdout. All operational logging goes to stderr so stdout remains reserved for JSON-RPC. Both example tools are pure functions with bounded inputs.
