Free AI visibility checks for any website: AI crawler access, llms.txt, schema, business info.

已验证Streamable HTTP可网页运行网页搜索与抓取数据与分析

概览

AI 生成的概览

免费的托管检查服务，让助手判断 AI 爬虫和 AI 工具能否访问并读取某个网站。

可以做什么
  • 检查 AI 爬虫访问：读取 robots.txt，报告 13 种 AI 爬虫各自被允许还是被屏蔽，以及首页对它们是否可加载
  • 检查 llms.txt：报告是否存在 /llms.txt、其大小与标题，并按行号列出不符合格式之处
  • 检查结构化数据：报告业务类型以及哪些 schema.org 字段存在、缺失或看起来有问题
  • 检查可读的业务信息：报告名称、电话、邮箱、地址、营业时间和价格是否以文本形式出现而无需运行脚本
  • 生成 robots.txt 规则：放行 AI 搜索爬虫、屏蔽训练爬虫，并可指定需保密的路径
  • 快速可见性检查：就业务向 3 个 AI 模型提出 3 个典型客户问题并汇总结果
适用场景
适合想弄清网站为何不出现在 AI 回答中、需要审查 AI 爬虫规则、llms.txt 或业务结构化数据，或需要现成的 AI 爬虫 robots.txt 规则时使用。
运行要求
远程 streamable HTTP 端点，无需安装。无需注册、API 密钥或身份验证。每次调用针对一个公开网站。按调用方和按网站均有限流。
安装前请注意
只读且仅抓取公开页面，但每次检查都会被记录，包括 URL 中可选的客户端名称。快速可见性检查会把网站公开内容发送给 AI 模型。多模型完整报告是另外的付费产品。

Preferly MCP server

Free AI visibility checks for any website, inside Claude, ChatGPT, Cursor, VS Code and any other AI tool that speaks the Model Context Protocol (MCP). Ask your assistant whether AI crawlers can reach a site, whether its llms.txt and business schema are right, and whether AI can read its hours and prices, and it runs Preferly's checks for you.

https://www.preferly.ai/mcp

Streamable HTTP · No sign-up · No API key · Read-only

This is a hosted (remote) server, so there is nothing to install or run. This repository holds the documentation and ready-made configs. The server itself runs at preferly.ai.

[Add to Cursor] [Install in VS Code] [Install in VS Code Insiders]

Tools

Every tool is read-only and works on one public website per call. None of them changes anything on the site.

ToolInputWhat it does
check_ai_crawler_accesswebsiteWhether the site's robots.txt lets 10+ AI crawlers in (GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended and more) and which rule decides each one; whether the homepage loads for them or shows a bot check; whether it has /llms.txt; its structured data types.
generate_ai_robots_txtallow_search (default true), allow_training (default false), optional disallow_pathsrobots.txt lines that let AI search and assistant crawlers in and keep training crawlers out, or any mix. Fetches nothing.
check_llms_txtwebsiteWhether the site publishes /llms.txt, its size and title, and what doesn't follow the llmstxt.org format, with line numbers.
check_business_schemawebsiteThe business described in the homepage's structured data (JSON-LD): its type, and which fields are present, missing or look off.
check_business_infowebsiteWhether the site's name, phone, email, address, hours and prices are readable as text without running scripts.
quick_ai_visibility_checkwebsiteAsks 3 AI models 3 typical customer questions about the business, from its public website, and reports whether each named it and where one contradicts the website.

The live list is always in the server card and the server's tools/list.

Set up

Most clients only need the URL. Adding ?client=<your tool> helps us count which tools people use; it's optional.

Any client, one command

bash
npx add-mcp https://www.preferly.ai/mcp

add-mcp finds the MCP clients on your computer and adds Preferly to them.

Claude Code

bash
claude mcp add --transport http preferly "https://www.preferly.ai/mcp?client=claude"

Claude (claude.ai and Claude Desktop)

Open Settings → Connectors → Add custom connector.

  • Name: Preferly
  • URL: https://www.preferly.ai/mcp?client=claude

Leave authentication empty and save. Then turn Preferly on from the tools menu in a chat. Custom connectors are available on Claude's paid plans.

ChatGPT (developer mode)

In ChatGPT on the web, open Settings → Apps → Advanced settings, turn on Developer mode, then choose Create app.

  • Name: Preferly
  • MCP server URL: https://www.preferly.ai/mcp
  • Authentication: No authentication

Whether developer mode is available depends on your plan and workspace settings. A listed Preferly app for ChatGPT is in review.

Cursor

Use the Add to Cursor button above, or add this to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):

json
{  "mcpServers": {    "preferly": { "url": "https://www.preferly.ai/mcp?client=cursor" }  }}

VS Code (GitHub Copilot)

Use the Install in VS Code button above. You can also run MCP: Add Server → HTTP and paste https://www.preferly.ai/mcp?client=vscode, or add this to .vscode/mcp.json:

json
{  "servers": {    "preferly": { "type": "http", "url": "https://www.preferly.ai/mcp?client=vscode" }  }}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

json
{  "mcpServers": {    "preferly": { "serverUrl": "https://www.preferly.ai/mcp?client=windsurf" }  }}

Cline

Open the MCP Servers panel → Remote Servers, name it preferly and paste https://www.preferly.ai/mcp?client=cline. You can also add this to cline_mcp_settings.json:

json
{  "mcpServers": {    "preferly": { "type": "streamableHttp", "url": "https://www.preferly.ai/mcp?client=cline" }  }}

To let Cline set it up for you, point it at llms-install.md.

Codex

bash
codex mcp add preferly --url "https://www.preferly.ai/mcp?client=codex"

Gemini CLI

Add to ~/.gemini/settings.json:

json
{  "mcpServers": {    "preferly": { "httpUrl": "https://www.preferly.ai/mcp?client=gemini" }  }}

Goose

Run goose configure → Add Extension → Remote Extension (Streamable HTTP), name it preferly and use https://www.preferly.ai/mcp?client=goose.

Zed

Add to your Zed settings.json:

json
{  "context_servers": {    "preferly": { "url": "https://www.preferly.ai/mcp?client=zed" }  }}

If your Zed version only runs local servers, use the bridge instead: "command": "npx", "args": ["-y", "mcp-remote", "https://www.preferly.ai/mcp?client=zed"].

Hermes Agent

bash
hermes plugins install preferly-ai/preferly-hermes --no-enablehermes plugins enable preferly

The plugin (preferly-ai/preferly-hermes) adds the server plus a skill that tells Hermes when to use each tool.

Other clients

Point the client at https://www.preferly.ai/mcp (streamable HTTP, no auth). If it only runs local (stdio) servers, use mcp-remote:

json
{  "mcpServers": {    "preferly": { "command": "npx", "args": ["-y", "mcp-remote", "https://www.preferly.ai/mcp"] }  }}

A generic config is in mcp.json.

Try asking

  • "Can AI crawlers read example.com?"
  • "Does my robots.txt block GPTBot or ClaudeBot?"
  • "Write robots.txt lines that let AI search crawlers in, keep training crawlers out, and keep /admin private."
  • "Does example.com have a valid llms.txt?"
  • "Is the business schema on example.com complete?"
  • "Can AI read the phone number, hours and prices on example.com without running scripts?"
  • "What do AI assistants say about the business at example.com?"

Limits, privacy and safety

  • Free, no sign-up and no key. Each caller gets 10 calls an hour and 30 website checks a day. Each website gets at most 20 fresh checks a day across all callers. A check for the same website in the last 10 minutes may be reused.
  • The website checks fetch only public pages: robots.txt, the homepage, /llms.txt, and at most 2 contact, booking or pricing pages that robots.txt allows. They identify themselves as PreferlyBot. They never log in, submit forms or change anything.
  • generate_ai_robots_txt fetches nothing.
  • Only quick_ai_visibility_check calls AI models, and it uses only what the website says publicly.
  • Preferly records each check and the client name you pass in ?client= to apply these limits and count usage. See the privacy policy.

What these checks don't do

They check whether AI can reach and read a website, not what AI assistants actually say about a business. For that, Preferly's full report asks 10 leading AI models about your business, quotes every place they contradict your website, and gives you the fixes ready to paste, for $99 once. See an example report.

check_ai_crawler_access

Check AI crawler access

Use this when the user wants to know whether AI crawlers and AI tools can access a specific website. It reads the site's robots.txt and reports, for 13 AI crawlers (including GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot and Google-Extended), whether each is allowed or blocked and which rule decides it. It also reports whether the homepage loads for an automated visitor or shows a bot check (such as Cloudflare, SiteGround or AWS WAF), whether the site publishes /llms.txt, and which schema.org types the homepage declares. Input: one public website address. It fetches only robots.txt, the homepage and /llms.txt, identifying itself as PreferlyBot, and changes nothing on the site. A result for the same domain may come from a check run in the last 10 minutes. It does not report what AI tools say about the business, search rankings, or pages other than the homepage.

输入参数website必填

check_llms_txt

Check llms.txt

Use this when the user asks whether a website has an llms.txt file or whether it's set up correctly. It fetches /llms.txt and reports whether it was found, its size and title, and every place it doesn't follow the llmstxt.org format (missing H1, no summary line, links that aren't Markdown or https), with line numbers. It also lists the homepage's main pages, which can seed a new llms.txt. Input: one public website. Reads robots.txt, the homepage and /llms.txt as PreferlyBot; changes nothing.

输入参数website必填

check_business_schema

Check business structured data

Use this when the user asks whether a website's structured data (schema.org JSON-LD) describes the business correctly. It reads the homepage's JSON-LD and reports the business type it found (Organization, LocalBusiness or a subtype), which business fields are present, missing or look off (name, url, phone, address, hours and more), and where the structured data and the page disagree. Input: one public website. Reads robots.txt, the homepage and /llms.txt as PreferlyBot; changes nothing.

输入参数website必填

check_business_info

Check readable business info

Use this when the user asks whether AI tools can read a business's details from its website. It reports whether the business name, phone number, email, address, opening hours and prices are readable as text in the page, only appear after scripts run, or weren't found, on the homepage and up to 2 contact, booking or pricing pages that robots.txt allows. Input: one public website. Reads robots.txt, the homepage, /llms.txt and up to 2 more pages as PreferlyBot; changes nothing.

输入参数website必填

generate_ai_robots_txt

Generate AI robots.txt lines

Use this when the user wants robots.txt lines that control which AI crawlers may read their website. By default it lets AI search and assistant crawlers in (so the site can appear in AI answers) and keeps AI training crawlers out; either can be switched. Optional paths are kept private from every allowed crawler. It returns the lines to paste into robots.txt and which crawlers each group covers. It fetches nothing and needs no website.

输入参数allow_searchallow_trainingdisallow_paths

quick_ai_visibility_check

Quick AI visibility check

Use this when the user asks what AI assistants say about a specific business, or whether AI tools mention or recommend it. Given the business's public website, it reads the site (robots.txt, the homepage and up to 2 contact, booking or pricing pages), writes 3 typical customer questions, and asks 3 AI models each question, answering from what they already know (no web search). It reports, for each model, whether it named the business and where it ranked when it gave a list, up to 2 statements where an AI model contradicts the website, and a one-line crawler summary. Input: one public website and, optionally, the business name. A result for the same website may come from a check run in the last 24 hours. Changes nothing on the site.
