已验证Streamable HTTP可网页运行网页搜索与抓取开发者工具

概览

AI 生成的概览

CitedBy 是一个免费、只读的远程 MCP 服务器,用于检查网站能否被 AI 助手和搜索引擎发现并引用。

可以做什么
  • 检查单个页面在 SEO 和 AI 回答方面的问题,并给出每项问题的原因和具体修复方法
  • 测试 robots.txt 和服务器是否允许 GPTBot、PerplexityBot、ClaudeBot 等指定 AI 爬虫访问
  • 检查站点是否有可用的 /llms.txt 和 /llms-full.txt,没有时提供草稿
  • 基于 Common Crawl 数据报告有多少域名链接到某域名,以及最强的引用来源
适用场景
适合在审计或改善网站对 AI 助手和搜索引擎的可见性时使用,也适合回答关于某域名的爬虫访问、llms.txt 和外链的问题。
运行要求
远程 Streamable HTTP 端点 citedby.eu/mcp;无需账号、登录、API 密钥或本地运行时。每个地址每小时限 40 次检查,结果最多复用 6 小时(页面检查为 1 小时)。
安装前请注意
只读且免费,但它会以自己的爬虫身份抓取公开页面和 robots.txt,目标站点会看到这些请求。整站审计和更高的页面上限需要在提供方网站购买付费方案。外链数据仅覆盖 .eu、EU 和英国国家域名下拥有 100 个以上引用域名的域名,以及链接最多的 5,000 个站点。

README

CitedBy MCP server

Ask your AI tool to check whether a website can be found and cited by AI assistants and search engines. Free, no account, read-only.

Server address: https://citedby.eu/mcp (MCP Streamable HTTP, no sign-in). Page with the same instructions: https://citedby.eu/mcp-server

Tools

ToolWhat you get
check_pageOne page, fetched as CitedBot (robots.txt respected): what is wrong for AI answers and search, each finding with why it matters and the exact fix. Deterministic checks only.
check_ai_crawler_accessFor GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended, Bingbot and Googlebot: allowed by robots.txt, and answered by the server, or not.
check_llms_txtWhether /llms.txt exists, whether its links work, whether /llms-full.txt exists.
backlinksHow many domains link to a domain, and the strongest ones, from the Common Crawl web graph. Says when a domain is not in the data.

When a site refuses the crawler or does not answer, the tool says so. It does not score what it could not read.

Install

Claude Code

claude mcp add --transport http citedby https://citedby.eu/mcp

or install the plugin, which also adds a skill that picks the right tool for the question:

/plugin marketplace add resaleiq/citedby-mcp/plugin install citedby@citedby

Claude on the web and desktop: Settings, Connectors, Add custom connector, paste https://citedby.eu/mcp.

Cursor: add CitedBy to Cursor, or add to ~/.cursor/mcp.json:

json
{ "mcpServers": { "citedby": { "url": "https://citedby.eu/mcp" } } }

Codex

codex mcp add citedby --url https://citedby.eu/mcp

Any other MCP client: add a remote server with the address above.

Ask it like this

  • "Check https://example.com/pricing with CitedBy and tell me what to fix first."
  • "Can GPTBot and PerplexityBot read example.com?"
  • "Does example.com have a working llms.txt?"
  • "Which domains link to example.com?"

Limits

40 checks an hour from one address; a result is reused for up to 6 hours (1 hour for a page check). check_page is one page. A whole-site audit, with every page up to your plan's limit and the exact fix for each, is at https://citedby.eu/plans.

Check your own site in the browser, free, no account (up to 10 pages): https://citedby.eu/?utm_source=github&utm_medium=referral&utm_campaign=citedby_202611&utm_content=mcp_readme
