web-server is a skill for Claude Code, Codex from PPParticle/web-server. It costs 49 tokens per session (1,182 once invoked), scanned A, original, MIT.

An MCP server guide for searching and reading web pages, GitHub repositories, research papers, Stack Overflow answers, and Reddit posts.

In plain words
What is it for?
It is for technical and academic research, reading web pages, finding papers, and exploring linked sources.
Why use it?
It explains how to find relevant sources and then read the most useful results instead of relying on search titles alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-server scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Web Server MCP 使用指南

两个工具,组合使用:搜索 → 读取。

web_search(query, topic?, domains?, num?)
  • topic="academic" → 搜 arxiv/dblp/semanticscholar/github(论文+代码)
  • topic="technical" → 搜 stackoverflow/github/dev.to/MDN(文档+问答)
  • topic="community" → 搜 reddit/HackerNews(讨论+评测)
  • domains=["site.com"] → 自定义站点限定(覆盖 topic)
  • 不设 topic/domains → 全网搜

read_url: 读网页内容

read_url(url, engine?, no_cache?, with_links?)
  • 默认 engine="auto":自动识别 GitHub/arXiv/SO/Reddit 走 API(结构化),其他走 Readability,SPA 降级 Playwright
  • engine="playwright":强制浏览器渲染(JS 页/反爬站)
  • no_cache=true:强制刷新
  • with_links=true:末尾附正文链接列表(供你决定是否递归探索)

典型工作流

研究一个技术话题

1. web_search("topic", topic="technical") → 拿到 SO/博客 URL 列表
2. read_url(url) → 读最有价值的 1-2 篇
3. with_links=true → 看正文里的链接,决定是否深入

读论文

1. web_search(..., topic="academic") → 论文 URL 列表(注意 fan-out,见下节)
2. read_url("https://arxiv.org/abs/xxxx") → 结构化 metadata(标题/作者/摘要)
3. 需要全文?read_url("https://arxiv.org/html/xxxx") 或手动下载 PDF

学术搜索:关键词 fan-out 策略(重要)

topic="academic" 走 DBLP / arXiv / Semantic Scholar。DBLP 是论文库,按标题精确匹配关键词(多词 query 是 AND 语义,标题里不全有就返回 0)。所以绝不能只发一个字面 query,要对同一研究主题并行发多个 query 变体,合并去重:

  • 同义词替换:offload / offloading / spill / swap / evict / displace
  • 存储/介质词:SSD / disk / NVMe / storage / tier / hierarchy
  • 缩写展开:KV cache / KV-cache / key-value cache
  • 子集拆分:多词 query 拆成 2-3 词子 query 再并行 —— kv cache offloading storage → kv cache ssd + kv cache disk + kv offloading + kv cache storage(单发原词返回 0,拆开后能命中标题含 SSD/disk 的论文)
  • 已知系统名:研究某领域时直接搜代表性系统名(KV offload 领域:mooncake、flexgen、vllm、tutti、infercept)
  • 目标 venue:按会议名搜(OSDI / SOSP / ASPLOS / FAST / SIGMOD / ICDE / VLDB / ISCA / MICRO)

流程:并行发 3-6 个 query 变体 → 合并所有结果去重(按 URL)→ 按相关度/年份筛 → read_url 读 1-3 篇高价值论文。

残留缺口:若领域全新且你不知道任何系统名,纯标题搜仍可能漏(标题词汇与你 query 完全正交时)。此时考虑改 domains 或全网 topic 搜补充。

读 GitHub 项目

read_url("https://github.com/owner/repo") → 原始 README(1:1 markdown)
read_url("https://github.com/owner/repo/issues/123") → issue + 评论(API 结构化)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

web-server is a skill published in the GitHub repository PPParticle/web-server (1 stars, last pushed 3mo ago), licensed MIT. It adds 49 tokens to every session and 1,182 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls).
