A token-saving MCP proxy that intercepts and compresses large tool returns into previews with on-demand handles. Reduces API token usage by up to 99% while maintaining Claude and OpenClaw compatibility.
Yang1Bai/clawtsaver is an intelligent MCP (Model Context Protocol) proxy designed to dramatically reduce token consumption when using large language models with external tools. It intercepts oversized tool returns and replaces them with compact previews plus on-demand access handles, enabling users to fetch full content only when needed. Real-world benchmarks show 99.1% token savings on typical operations like Wikipedia fetches (11,507 tokens reduced to 104 tokens).
Installation involves cloning the repository from GitHub and configuring it as an MCP proxy between your Claude or OpenClaw instance and your tools. The tool is designed to be compatible with multiple platforms (Windows, macOS, Linux) as indicated by the emoji support. Follow the GitHub repository documentation for platform-specific setup instructions and configuration of tool intercepts.
