What is LiteCode?

LiteCode is an open-source, ultra-lightweight Coding MCP (Model Context Protocol) server built with Rust. It provides a streamlined set of developer tools consistent with Claude Code, while stripping away non-essential functionality to achieve minimal footprint and maximum performance.

✨ Features

  • 🦀 Lightweight — Minimal binary size and resource usage, powered by Rust's zero-cost abstractions
  • 🔌 Compatible — Tool interface consistent with Claude Code for seamless workflow transfer
  • 🎯 Focused — Only essential coding tools, no bloat
  • 🌐 Flexible Transport — Supports both STDIO and Streamable HTTP
  • 🔓 Open Source — Community-driven development with a transparent roadmap

🛠️ Tools

LiteCode ships with 9 core tools:

Tool Category Description
Bash Execution Run shell commands with background task support
Read File I/O Read files (code, images, PDFs, Jupyter notebooks)
Write File I/O Create or overwrite files
Edit File I/O Exact string replacement in files
Glob Search Find files by glob pattern
Grep Search Search file contents by regex (ripgrep-powered)
NotebookEdit File I/O Edit Jupyter notebook cells
TaskOutput Task Mgmt Retrieve background task output
TaskStop Task Mgmt Terminate background tasks

📦 Installation

Build from source

git clone https://github.com/mirrorange/LiteCode.git
cd LiteCode
cargo build --release

The compiled binary will be at target/release/litecode.

Install via cargo

After the crate is published to crates.io, you can install it directly with:

cargo install litecode

If you want a specific release:

cargo install litecode --version 0.1.0

🚀 Usage

STDIO Mode (Local)

litecode stdio

Best for local IDE integrations, CLI tools, and embedded agents.

Streamable HTTP Mode (Remote)

litecode http --host 0.0.0.0 --port 8080

Best for remote servers, cloud deployments, and multi-client access.

🤝 Contributing

Contributions are welcome! Please feel free to submit issues and pull requests.

🚢 Release Process

  • Every push and every pull request runs GitHub Actions CI on Linux, Windows, Intel macOS, and Apple Silicon macOS.
  • Creating a tag like v0.1.0 triggers the release workflow.
  • The release workflow verifies that the tag matches Cargo.toml, builds release binaries for each platform, uploads archives to GitHub Releases, and publishes the crate to crates.io.
  • To enable crates publishing, add the repository secret CARGO_REGISTRY_TOKEN with a crates.io API token that has publish permission.

LiteCode 是什么?

LiteCode 是一个使用 Rust 构建的开源、超轻量级 Coding MCP(Model Context Protocol)服务器。它提供了一套与 Claude Code 一致的精简开发者工具集,同时去除了非必要功能,以实现最小体积最高性能

✨ 特性

  • 🦀 轻量级 — 极小的二进制体积和资源占用,得益于 Rust 的零成本抽象
  • 🔌 兼容性强 — 工具接口与 Claude Code 保持一致,无缝迁移现有工作流
  • 🎯 专注核心 — 仅包含必要的编码工具,无冗余功能
  • 🌐 灵活传输 — 同时支持 STDIO 和 Streamable HTTP 两种传输模式
  • 🔓 开源开放 — 社区驱动开发,路线图透明公开

🛠️ 工具集

LiteCode 提供 9 个核心工具

工具 分类 描述
Bash 执行 运行 Shell 命令,支持后台任务
Read 文件 I/O 读取文件(代码、图片、PDF、Jupyter 笔记本)
Write 文件 I/O 创建或覆写文件
Edit 文件 I/O 文件内精确字符串替换
Glob 搜索 按 glob 模式匹配查找文件
Grep 搜索 按正则表达式搜索文件内容(基于 ripgrep)
NotebookEdit 文件 I/O 编辑 Jupyter Notebook 单元格
TaskOutput 任务管理 获取后台任务输出
TaskStop 任务管理 终止后台任务

📦 安装

从源码构建

git clone https://github.com/mirrorange/LiteCode.git
cd LiteCode
cargo build --release

编译后的二进制文件位于 target/release/litecode

通过 cargo 安装

crate 发布到 crates.io 后,可以直接安装:

cargo install litecode

如果要安装指定版本:

cargo install litecode --version 0.1.0

🚀 使用方法

STDIO 模式(本地)

litecode stdio

适用于本地 IDE 集成、CLI 工具和嵌入式 Agent。

Streamable HTTP 模式(远程)

litecode http --host 0.0.0.0 --port 8080

适用于远程服务器、云部署和多客户端访问。

🤝 参与贡献

欢迎贡献代码!请随时提交 Issue 和 Pull Request。

🚢 发布流程

  • 每次推送和每次提交 Pull Request 时,GitHub Actions 都会在 Linux、Windows、Intel macOS 和 Apple Silicon macOS 上执行构建与测试。
  • 创建类似 v0.1.0 的 tag 会触发发布工作流。
  • 发布工作流会校验 tag 与 Cargo.toml 中的版本一致,为各平台构建发布包,上传到 GitHub Releases,并把 crate 发布到 crates.io。
  • 要启用 crates 发布,请在仓库中配置 CARGO_REGISTRY_TOKEN secret,并填入具有发布权限的 crates.io API Token。
