No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
LeanCTX compresses file reads, shell output, and search results for AI agents. LeanCTX uses tree-sitter AST analysis for read compression across 27 languages. LeanCTX offers 95+ compression patterns for tools like git, cargo, npm, and docker.
LeanCTX includes persistent memory via a knowledge graph that retains information across sessions. LeanCTX supports agent coordination through an agent bus, shared sessions, and handoff protocols. LeanCTX runs as an MCP server compatible with multiple agents such as Cursor, Claude Code, and GitHub Copilot.
