Lean Ctx slashes LLM token consumption by 99%
Lean Ctx is a Rust-based hybrid context optimizer that reduces LLM token consumption using shell hooks and an MCP server. It employs specialized protocols for cognitive efficiency and cross-session memory to keep context windows lean and focused while providing agents with persistent task history.
// ANALYSIS
Lean Ctx treats LLM context as a protocol design problem rather than just raw text, bypassing the bloat of standard formats like JSON.
- –Reduces token costs by 89-99% via specialized compression, AST-based chunking, and custom shorthand
- –Context Continuity Protocol (CCP) provides persistent memory across sessions, a major win for stateless agents
- –TDD (Token Dense Dialect) uses symbol shorthand for extremely high information density and reduced "thinking" tokens
- –Built in Rust with zero dependencies, making it fast and easy to install across environments
- –MCP server integration with 24 tools allows it to be used in Cursor, Windsurf, or custom agents
