LeanKG

概述

LeanKG 是一个基于 Rust 的本地知识图谱，专为 AI 编程工具提供准确的代码库上下文。它索引代码文件，构建依赖关系图，并通过 MCP 服务器使 AI 工具（如 Cursor、OpenCode 和 Claude Code）能够直接查询知识图谱。系统提供影响半径计算、依赖关系图可视化、令牌优化和多语言支持等功能。与基于云的解决方案不同，LeanKG 本地运行，无需外部数据库依赖，解决了 AI 工具处理完整代码库上下文时的高 token 消耗问题。

FAQ

LeanKG 支持哪些 AI 工具？

LeanKG 支持 Cursor、Claude Code、OpenCode、Kilo Code、Gemini CLI、Google Antigravity 和 Codex，集成程度包括自动设置、会话钩子和插件。

LeanKG 如何减少 token 消耗？

LeanKG 构建知识图谱，使 AI 工具可以查询特定子图，而不是处理完整代码库上下文，将 token 消耗从 15,000-45,000 减少到相关代码。

LeanKG 是基于云的吗？

不是，LeanKG 是本地优先的解决方案，完全在您的机器上运行，无需云服务或外部数据库依赖。
