👁️ NetReach — no-login 版

给你的 AI Agent 一键装上互联网「只读 + 搜索」能力 —— 只收录无需登录、爬虫风险低的公开数据源。


支持的平台(全部零配置,无需登录)

平台 能力 后端
🌐 网页 读任意网页 → Markdown Jina Reader(curl r.jina.ai/URL)
📺 YouTube 字幕提取 + 视频搜索 yt-dlp
📡 RSS 解析任意 RSS/Atom 源 feedparser
📦 GitHub 公开仓库 + 代码搜索 gh CLI(公开数据无需登录)
💻 V2EX 热门/节点/帖子详情+回复/用户 公开 API
📺 B站 搜索 + 视频详情(无需登录) bili-cli ▸ 搜索 API
🔍 全网搜索 AI 语义搜索 Exa(mcporter MCP,免费无需 Key)

⚠️ 注意:B站字幕需要浏览器登录态,不在本版本范围内(不登录只能搜视频、看详情)。


设计理念

NetReach 是一个能力层(capability layer),不是又一个工具。

它负责选型、安装、体检、路由,不负责底层读取本身。读取由 Agent 直接调用上游工具(yt-dlp、gh、feedparser、bili-cli 等)完成,没有包装层。

每个平台 = 首选 + 备选的有序后端列表。换接入方式 = 调整列表顺序,不是重写代码。agent-reach doctor 会告诉你每个平台当前在用哪个后端。

channels/
├── web.py          → Jina Reader
├── youtube.py      → yt-dlp
├── rss.py          → feedparser
├── github.py       → gh CLI
├── v2ex.py         → V2EX 公开 API(直接 HTTP 实现)
├── bilibili.py     → bili-cli ▸ B站搜索 API
├── exa_search.py   → Exa via mcporter
└── __init__.py     → 渠道注册

每个渠道文件按序真实探测各候选后端(不只是看命令存不存在),第一个完整可用的当选;坏掉的会给出修复处方。


快速上手

# 安装(默认安全检查,只读不改系统)
agent-reach install --env=auto

# 显式授权安装系统依赖 + 注册 skill
agent-reach install --env=auto --system

# 体检:一条命令看每个渠道通不通、走哪个后端
agent-reach doctor

安装完直接告诉 Agent 就行,不用记命令:

  • "看看这个链接" → curl https://r.jina.ai/URL
  • "这个 GitHub 仓库是干嘛的" → gh repo view owner/repo
  • "这个 YouTube 视频讲了什么" → yt-dlp 提取字幕
  • "B站搜一下 AI 教程" → bili search "AI 教程"
  • "全网搜 LLM 框架对比" → Exa 语义搜索
  • "订阅这个 RSS" → feedparser

Agent 读取 SKILL.md 后自己知道该调什么。


安装的系统依赖

install --system 会安装以下外部工具(--safe/默认模式只检查、不安装):

工具 用途
gh CLI GitHub 读取/搜索
Node.js yt-dlp JS runtime + mcporter
mcporter + Exa 全网语义搜索
bili-cli B站搜索/详情(可选)

安全性

措施 说明
🔒 无凭据 本版本不需要 Cookie/Token,配置仅存一个可选的网络代理
🛡️ 默认安全 install 默认只检查不改系统;显式 --system 才安装工具
👀 完全开源 代码透明,随时可审查
🔍 Dry Run install --dry-run 预览所有操作,不做任何改动
🧩 可插拔 不信任某个组件?换掉对应 channel 文件即可

命令参考

agent-reach install --env=auto [--system | --safe] [--dry-run] [--proxy=...]
agent-reach doctor [--json]
agent-reach version
