Control what your AI can see. LeanCTX (Lean Context) is the context intelligence layer for AI agents — one local Rust binary that decides what they read, remembers what they learn, guards what they touch, and proves what they save. 60–90% fewer tokens as the receipt. 76 MCP tools, 30+ agents, local-first.
LeanCTX is a Rust-based MCP server that sits between AI coding agents and a codebase to compress, cache, and govern the tokens flowing into the model's context window. It exposes over 30 tools covering file reads in a "map mode" that strips noise to roughly 13 tokens per cached re-read (compared to around 2,000 for a raw read), shell output compression that shrinks a typical `git status` from about 800 tokens to 120, cross-session memory that persists context between chats, and a real-time `lean-ctx gain` dashboard showing token and dollar savings live. The binary installs via a single `lean-ctx setup` command and connects to Claude Code as well as Cursor, Copilot, Windsurf, and Gemini CLI with no additional configuration. Developers paying Claude API costs directly, or teams running long agentic coding sessions where repeated file reads and verbose shell output erode the usable context window, are the primary audience. The project claims 60 to 90 percent fewer tokens consumed overall, backed by reproducible benchmark reports generated from VHS tapes included in the repository.
