run_auditRun a cloud audit | Run a cloud audit of a website (crawl + 260+ rule analysis + report). Credits are spent as the audit runs (pay-as-you-go). The dry run is optional: pass confirm: true on the first call to start straight away. Without… | writes |
get_audit_statusGet audit status | Poll a running audit by run_id (from run_audit or list_audits). Status pending/running means keep polling (every 15-30 seconds): the response includes a progress field (phase, message, page/link counts) when available.… | read-only |
list_auditsList audits | List the organization's audit runs: currently active (pending/running) plus recent runs of any status. Pass website_id (from list_websites) to get one website's full audit history, oldest runs included, and page through… | read-only |

delete_websiteDelete a website | Delete a website from the organization (soft delete: past audits, reports, and issues are preserved, and published report links keep working). Frees a slot under the plan's website limit. Re-adding the same domain later… | writes |
delete_websitesDelete websites in bulk | Delete up to 50 websites in one call, for cleaning up a dashboard that has filled with one-off or prospect audits. Same soft delete as delete_website (past audits, reports, and issues are preserved, published report… | writes |

compare_auditsCompare two audits | Compare two completed audits of one website and get what changed. Defaults to the website's latest completed audit against the one before it; pass base/head run ids to compare any two. Each finding gets one of seven… | read-only |
list_issuesList website issues | List a website's open audit issues (like a bug tracker: each issue is one failing rule with occurrences across pages, numbered per website). Returns issues sorted by severity, plus severity and status summaries. Use the… | read-only |
get_issueGet issue detail | Fetch one issue by website_id + issue number, including its full description, recommendation, affected pages, occurrence detail from the latest report (which page/image/URL, snippets), and comment thread. Use… | read-only |
comment_on_issueComment on an issue | Post a comment on a website issue — use it to record analysis, a proposed fix, or what you changed, so the team sees it in the dashboard issue thread. Markdown is supported. | writes |
list_entitiesList declared entities | List the entities a site declares in its JSON-LD, collapsed across every crawled page into one graph, so an Organization declared identically on 60 pages is one row rather than 60. Declarations collapse by resolved @id,… | read-only |
get_entityGet one declared entity | Get one entity as the map recorded it: the properties the map keeps (name, url, logo, image, sameAs, telephone, email, address, description), the pages that declare it, the properties whose values disagree between those… | read-only |
get_entity_graphExport the entity graph | Get the whole entity graph, or a filtered part of it, in a chosen format: json for the canonical document, jsonld for a validator, mermaid or markdown to read in a conversation, dot or graphml for a graph tool. Defaults… | read-only |
compare_entitiesCompare two audits' entities | Compare two audits of a site and get the change set: entities added and removed, entities that gained or lost an @id, occurrence changes, new and resolved conflicts and dangling references, summary deltas, and the pages… | read-only |
get_entity_findingsGet the entity rule findings | Get the schema/entity-* rule verdicts for an audit: what is wrong with the site's entity graph, which entity keys and pages each finding affects, and the fix text for each. Use this instead of re-deriving the problems… | read-only |
list_rulesList audit rules | Browse the catalog of 260+ audit rules that run during an audit, grouped into categories (crawlability, meta tags, performance, security, accessibility, content, and more). Filter by category code or search by keyword… | read-only |
get_ruleGet rule detail | Fetch one audit rule by id (e.g. "meta/title-length"), including what it checks, how to fix it (recommendation), its severity and score weight, a docs link, and whether it is a cloud (credit-billed) rule. Rule ids… | read-only |
whoamiWho am I | Identify the current credentials: how you are authenticated, which organization you act for, the plan, and the current credit balance. Call this first in a session to orient yourself before running audits. | read-only |
get_credit_balanceGet credit balance | Get the organization's credit balance: monthly credits (reset each billing period) and pack credits (purchased, never expire). Audits spend credits pay-as-you-go while they run; run_audit shows an upper-bound estimate… | read-only |
