Build a secure AI server with TypeScript: API keys, scopes, and rate limits

By PulseAugur Editorial · [1 sources] ·

This article details how to build a secure server for AI clients using TypeScript, focusing on API key management, scope enforcement, and rate limiting. It outlines a three-part system: API keys stored as SHA-256 hashes with associated scopes, a token bucket mechanism for each client to control request frequency, and a central wrapper to log and validate all tool calls. The implementation includes two example tools, `get_order_status` and `create_support_ticket`, demonstrating how scopes restrict access and how rate limiting prevents abuse. AI

IMPACT Enables developers to build more secure and manageable interfaces for AI agents, improving reliability and control in AI applications.

RANK_REASON The article describes the implementation of a specific software component for managing AI client interactions, rather than a new model release or significant industry event.

    Minimal MCP Server in TypeScript: API Keys, Scopes and Rate Limits

    <p>You can make an MCP server safe to hand to a real AI client with about 150 lines of TypeScript. You need three pieces: API keys that are stored as hashes and carry scopes, a token bucket for each client, and one wrapper that checks and logs every tool call. This post builds al…
