Questions it answers
Find what to fix on a public website, for search engines and for AI answers.
- audit_site: SEO audit of up to 25 pages, failed rules by priority with the fix and source, a row per page with broken internal links and images without alt, plus AI-search steps for the site owner. - audit_page: the same page rules for one address. - local_ai_readiness: whether a local business site is ready to be named in AI search. - score_page_citation: a 0 to 100 citation score for one page, with fixes by biggest gain. - compare_citations: what the pages an AI answer cited share that your page lacks. - find_ai_questions: long searches to answer, from a pasted Search Console export. - check_ai_instructions: checks a site's llms.txt, llms-full.txt and AI page. - generate_ai_instructions: drafts an llms.txt for the owner to review. - audit_ai_search: grades a site on 12 on-site checks AI answer engines rely on, pass, partial or fail, with the 3 biggest fixes, plus 15 AEO/GEO rows from Microsoft's guide to AEO and GEO.
It reads only the public sites you name, respects robots.txt and refuses private addresses. It does not run JavaScript, query search or AI engines, fetch directories, or measure rankings, traffic or backlinks. Scores and checks do not promise a citation or an effect on AI search answers.
Nothing about you or the site is stored. Answers are cached for ten minutes. The optional judgement step, off by default, sends page text to a language model service. It and local checks are limited per day.

Tools
audit_site, SEO audit (site). Use this to audit a whole site or several pages for SEO; it finds the pages itself. Never guess page addresses for requests such as "audit example.com", "which pages are worst?" or "my site has a page per city, are they too similar?". Pass the domain and optionally max_pages. Reads the homepage, sitemap and linked pages of that site, respecting robots.txt. Returns failed rules by priority, each with its pages, fix and docs link, plus a row per page with its status, broken internal links and images without alt text. It also compares pages: near-identical templated pages, pages with little own text, hreflang without return links or x-default, and sitemap pages nothing links to. Leave judge off unless the user asks what pages are for or which compete. It reads a sample, runs no JavaScript and measures no rankings, traffic or backlinks. For one named page use audit_page. Not for private or local addresses or to collect a site's content.score_page_citation, Citation score (page). Cite-chance score for one page, 0 to 100. Use this when the user asks whether ChatGPT, Perplexity or Google AI Overviews are likely to cite a page, or how to fix that. Pass exactly one of url, html, text, or sample. Returns the score and a fix list ordered by the biggest point gain. The checks cover an answer in the opening, question headings, an FAQ block, structured data, lists and tables, heading order, short sentences, a number with a source, a recent date, and an author line. Pasted html and text are scored as given and are not fetched. A url is one public page, with robots.txt respected. It does not call an AI engine and it does not promise a citation. Use compare_citations when the user has the pages an AI answer cited. Do not use it for private or local addresses, rankings, or traffic.find_ai_questions, Questions for AI search. Long-search finder for a pasted Search Console export. Use this when the user pastes Search Console Performance rows or a CSV and asks which questions to answer on their pages, or how to get named in ChatGPT or Google AI answers. Pass the text as csv, or JSON rows as rows, with query and impressions, and page if there is one. Up to 5000 rows. Returns the searches of 7 or more words ranked by impressions, marked when they look like questions. Each has the page Google shows, the question as a heading, and a 2-sentence answer skeleton with a placeholder for one real number or fact that only the owner knows. Also groups by page. It reads only what is pasted: no Google login, no Search Console call, no AI engine. It does not write the answer or invent the number. Not for a user with no export: ask them to paste one.compare_citations, Compare cited pages. Citation-pattern check for one query. Use this when the user has the pages an AI answer or Google AI Overview cited for a search and asks what they share, or why their own page is not cited. Pass query, cited_urls (2 to 6 public addresses the user copied from the answer) and exactly one of url, html or text for the user's page. Reads the public pages with robots.txt respected and returns the gaps first: each signal most cited pages share and the user's page lacks (opening answer, query words in a heading, question heading, table, list, date in the last year, links out, schema types, length), with counts such as 4 of 5 and a fix. Every signal is also listed per page. It reads no Google or AI engine, so the user must supply the cited addresses; never guess them. It stores nothing; change over days needs a new call later. A shared signal is a pattern in a small sample, not a proven cause, and no citation is promised. Do not use it for private addresses.audit_page, SEO audit (page). Use this only for a single page address the user gave, such as "what SEO problems does https://example.com/docs have?" or "is the title and description of this page OK?". Pass the page address. Returns the page rules that failed grouped by priority, each with the fix and the documentation link, plus the title, description, headings and other facts read. robots.txt is respected. For several pages, a whole site or finding pages, call audit_site once instead: it also runs the rules that compare pages or read the sitemap. Not for private or local addresses, rankings, traffic or reading a page's text. It does not measure speed or Core Web Vitals (LCP, CLS, INP); reach_check gives server response time per region.local_ai_readiness, Local AI-search readiness. Local-business readiness for AI search answers. Use this when the user asks if a local business site is ready to be named by AI search, ChatGPT, Gemini or similar, or what to fix so assistants can cite it. Pass the business's own site. Crawls only that site's public pages (robots.txt respected, up to 25, default 15) and returns pass, warn or fail for a page per service, location or service-area pages, visible prices, FAQ, LocalBusiness schema (name, address, phone, hours, geo, sameAs), NAP consistency, on-site proof, a one-line description and recent dated content. Each check has the evidence URL and a fix. Also returns what Gemini, OpenAI and Anthropic leaned on in a Yext study and profile advice, which is not fetched. It does not query AI engines, directories or review sites, or measure rankings. Not for a site with no physical location or service area: use audit_site. Do not use it for private addresses or to collect contact details.check_ai_instructions, Check AI instructions. Checks the site's AI instructions files and page. Use this when the user asks whether a site publishes llms.txt, llms-full.txt or an AI instructions page, whether the home page links to them, and whether the file matches the site's own name, products and facts. Pass the domain. Returns pass, warn or fail for each part, with the evidence URL and a fix, plus the date the pages were read. A public post is cited as the reason the check exists. It does not promise an effect on AI Overviews and does not query AI engines. For a local business site, use local_ai_readiness; to draft the file, use generate_ai_instructions. Do not use it for private addresses or to collect contact details.generate_ai_instructions, Draft an llms.txt. Drafts an llms.txt from the site's own public pages. Use this when the owner wants a draft AI instructions file to review. Pass the domain. Returns markdown for the owner to edit and publish themselves. Nothing is written to the site. A public post is cited as the reason the draft exists. It does not promise an effect on AI Overviews and does not query AI engines. Do not use it for private addresses or to collect contact details.audit_ai_search, AI search audit (12 checks). Grades a site on 12 on-site checks for AI search. Use it when the user asks whether ChatGPT, Claude, Perplexity or Google AI would recommend or cite their site, or wants a GEO audit. Pass the domain. Reads up to 10 public pages without JavaScript (robots.txt respected). Each check is pass, partial, fail or unknown with evidence and a fix: no-JS text, crawler access, llms.txt, what-is sentence, prices page, comparison page, 10 questions, Organization and Product markup, one name, named quotes, dates, an original number. Returns a score out of 12 and the 3 biggest fixes. unknown means the fetch could not prove the row and earns no point. Also 15 AEO/GEO rows from Microsoft's guide, pass, warn or fail. It does not query AI engines or promise a citation. Not for private addresses.
Add SEO Audit in Claude
Claude connects to a remote MCP server as a custom connector. The connection is made from Anthropic's cloud, not from your laptop, so the server must be on the public internet. SEO Audit is. These steps were checked against Claude's custom-connector article (updated 2026-08-11) and the Claude Code MCP docs on 2026-10-01.
On a Pro or Max plan:
- Open Customize, then Connectors.
- Select the plus button, then Add custom connector.
- Paste this URL. Leave Advanced settings empty: this server does not need an OAuth client id or secret.
https://seoaudit.openkrill.app/mcp - Select Add. The connector is yours. Anthropic has not reviewed it, and it is not a Directory listing.
- In a conversation, open the plus button, then Connectors, and enable SEO Audit. Ask: Audit example.com for SEO problems
On Team and Enterprise, an Owner adds the connector first at Organization settings, then Connectors, then Add, then Custom, then Web, and pastes the same URL. Members then connect it from Customize. A Free plan can add one custom connector.
In Claude Code, add it from the project directory:
claude mcp add --transport http seo-audit https://seoaudit.openkrill.app/mcpThat writes a local or user config. A JSON entry needs "type": "http" (or streamable-http) plus the url. An entry with a url and no type is skipped. Confirm with claude mcp get seo-audit. The tools you should see are audit_site, score_page_citation, find_ai_questions, compare_citations, audit_page, local_ai_readiness, check_ai_instructions, generate_ai_instructions, audit_ai_search.
If Claude tries to fetch https://seoaudit.openkrill.app/mcp from its code sandbox and reports HTTP 403, the block is Claude's sandbox network allowlist, not this server. The sandbox proxy answers 403 with x-deny-reason: host_not_allowed for every host outside the allowlist. Use the connector above instead: connector calls come from Anthropic's cloud and do not pass the sandbox proxy. To let the sandbox reach it as well, an Owner adds seoaudit.openkrill.app under Settings, then Capabilities, then Additional allowed domains.
Enable the connector only in conversations that need it. Claude can call the tools while you work, including during research, so turn off any tool you do not want invoked. SEO Audit does not write to your accounts. It still receives the arguments of each call. Read the privacy page before you paste anything that is not public.
If it does not work
The tool does not show up
In Claude, enable the connector in the conversation from the plus button, then Connectors. In Claude Code, run claude mcp list from the same directory you added it in, then start a new session: a running session does not load a new server.
429 or rate_limited
Each server takes 60 calls a minute from one network, and some tools take fewer. Past that the call comes back as a tool error that starts with rate_limited: wait a minute and ask again. daily_limit means the server reached its shared daily cap, which resets at 00:00 UTC. A limit is not an answer, so do not read it as no results. For higher limits, ask support@openkrill.app for a key.
JSON entry has no type
Claude Code skips an entry in .mcp.json that has a url but no type. Add "type": "http" next to the url, or add the server with claude mcp add --transport http, which writes the type for you. The VS Code entry needs the same type field. Cursor and Pi read the url alone.
A call checked on 2026-10-17
example.com is one public page. Judgement stays off, so no page text is sent to a language model. The request below was posted to https://seoaudit.openkrill.app/mcp as tools/call. HTTP 200. Source: the SEO Audit server, read 2026-10-17.
{
"method": "tools/call",
"params": {
"name": "audit_page",
"arguments": {
"url": "https://example.com",
"judge": false

}
- status. 200
- notice. This is what the site served to a request from Agent Tools servers right now, read with robots.txt respected and without running JavaScript. The rules follow Google Search Central documentation and common conventions; ru
- url. https://example.com/
- finalUrl. https://example.com/
Repeat the call yourself if you need a newer reading. Cached answers expire. A rate limit is not a result: wait and try again. Nothing in the call is a ranking, a filing, or advice.
Using it in production
Nothing to install and nothing to run: no package, no Python or Node.js version and no environment variable. SEO Audit runs on our servers, and your client only needs the URL https://seoaudit.openkrill.app/mcp.
| Rate limit | 60 tool calls a minute from one network. initialize and tools/list do not count. |
|---|---|
| Daily cap | 25000 tool calls a day per server, shared by every caller. It resets at 00:00 UTC. |
| At a limit | The call comes back as a tool error that starts with rate_limited (wait a minute) or daily_limit (try after 00:00 UTC), never as a partial answer. |
| Key | None. Do not add an Authorization header or a key field. |
| Higher limits | Email support@openkrill.app with the server name, the calls a day you expect and what they are for. We answer within 1 business day. |
| Freshness | Some answers come from a short cache. Each guide shows the date of its checked call; repeat a call when you need a newer reading. |
| Uptime | Scheduled test calls check the servers through the same endpoint. There is no SLA yet. |
