Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

check_citationsUse this when the user asks whether AI answer engines cite their website. Asks one answer engine (Perplexity) three customer-style questions written from the site's own pages and returns each question, the sites it cited, whether this site was one of them, and the date. A result for the same site from the last 24 hours is returned again instead of asking again.
describe_corpus_planread-onlyReturn Corpus Plan's public SEO/GEO audit capabilities, product links, and safety notes.
get_public_reportread-onlyRead the stored public audit report for a saved Corpus Plan share slug. Unsaved reports require saving through the website first. Only public report facts are returned.
get_report_progressread-onlyRead the current status and progress lines for a Corpus Plan audit behind a public report slug.
run_auditUse this when the user wants a website audited. Starts Corpus Plan's free audit of a public website (up to 20 pages of that site) and returns the overall score, the five pillar scores with AI citability first, the top three issues, the Product information document and the workspace link where the user can save the report. The same site audited from an AI assistant in the last 24 hours is returned again instead of re-crawled. If the result says running, call again with the same url.
