Show HN: TokenShield – Local proxy that dedupes Claude Code conversation traffic (www.npmjs.com)

TokenShield, developed by CuratedMCP, is a new local proxy tool designed to significantly reduce costs associated with the Claude Code AI service, offering savings of 40-70%. By deduplicating repeated responses within conversations and caching identical outputs, TokenShield ensures that API requests to Anthropic are efficiently streamlined without compromising user data, as no API keys or prompts leave the local machine. This tool is especially relevant for developers using Claude Code, where repeated prompts often lead to inflated token usage and costs. For the AI/ML community, TokenShield presents an effective solution to manage operational expenses in the growing landscape of AI services. It operates transparently, maintaining all user interactions locally while providing a dashboard to track savings in real-time. The tool uses advanced techniques like content hashing and a conservative cache system to enhance efficiency, making it a practical addition for anyone leveraging AI models that can incur hefty operational costs. TokenShield is also designed for ease of integration, allowing developers to start saving with minimal setup.
