rtk

Overview

rtk is a command-line proxy that sits between developer tools and LLMs, compressing tool outputs, logs, files, and RAG chunks so agents see the same information with 60–95% fewer tokens.[6][7] It can also run as an MCP server, making it drop-in for assistants that speak the MCP protocol and need cheaper context feeds from build systems, linters, or custom scripts.[6][7] Developers should care because it meaningfully lowers LLM spend and improves responsiveness on heavy workflows like test runs, CI logs, and large code searches without changing their existing tools.[6][7]
