run_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 confirm, an audit whose estimate is over the org's auto-run threshold comes back as status "confirmation_required" with the estimate to show the user, and you call again with confirm:
ArgumentsA call is made on an account: it counts against an allowance and the publisher sees it, which is why this one asks who you are first.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine — this server runs on the publisher’s own infrastructure behind our gateway, and what you install is the connection to it.

This is a public server: you run it yourself and this marketplace is not in the path. Claude Code registers it in one command.

Free to install, and it runs from its publisher’s own package: no account, no key, no card.
What it writes
One config entry pointing at the gateway. The server itself runs on the publisher’s own infrastructure, so nothing from this listing executes on your machine.

Takes no parameters.
Example callreturns →
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. Status completed means the report is ready: call get_report with the same run_id. Status failed/cancelled includes the error and completion reason.
Takes no parameters.
Example callreturns →
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 it with limit/offset using the returned total/has_more. This is the way to reach the preserved reports of a soft-deleted website: its runs still list under its old website_id. tota
Takes no parameters.
Example callreturns →
List websites the organization has audited, with their latest run status, health score, and owned/prospect kind. Each row carries last_run_id (the latest run, any status) and last_report_run_id / last_report_id (the latest completed run whose report has not been deleted) — pass last_report_run_id to get_report to read a website's newest report without knowing a run id in advance, or list_audits wi
Takes no parameters.
Example callreturns →
Register a website with the organization without running an audit (run_audit registers automatically, so this is only needed to set a site up ahead of time). Returns the website_id; idempotent per domain, so calling it again returns the existing website. Pass kind to classify it as owned or prospect up front.
Takes no parameters.
Example callreturns →
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 registers a fresh website with a new website_id. Call once without confirm to see what will happen; call again with confirm: true to delete. To remove many sites at once, use delet
Takes no parameters.
Example callreturns →
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 links keep working, slots are freed) and the same two-step confirm: call once without confirm to see the domain behind every id, then again with confirm: true. EVERY result echoes the
Takes no parameters.
Example callreturns →
Fetch the finished report for an audit run (use the run_id from run_audit once get_audit_status shows completed). Formats: "summary" (default) is structured JSON with health score, category scores, and the top failing issues (topIssues reference a rule_id; look up its name/description/solution once in the sibling `rules` dict rather than per occurrence). Each topIssues row carries `provenance`: "c
Takes no parameters.
Example callreturns →
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 issue number with get_issue for full detail and comments. Filter by status/severity/category to narrow down.
Takes no parameters.
Example callreturns →
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 comment_on_issue to add analysis or a fix note to the thread.
Takes no parameters.
Example callreturns →
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.
Takes no parameters.
Example callreturns →
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 to find what a specific rule checks. Use get_rule for one rule's full detail.
Takes no parameters.
Example callreturns →
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 appear in report topIssues and issue rule_id fields.
Takes no parameters.
Example callreturns →
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.
Takes no parameters.
Example callreturns →
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 before starting. Top up at https://app.squirrelscan.com/billing.
Takes no parameters.
Example callreturns →
Audit the organization's credit accounting log: grants (signup/monthly/pack/promo), debits (audit_base 50cr + render 2cr/page + folded 0-cost services), refunds, and adjustments — newest first, paginated. Each debit/refund carries `run_id` so you can group a single audit's spend. Use this to explain why an audit cost what it cost or to reconcile a balance. For one audit's per-feature breakdown, us
Takes no parameters.
Example callreturns →
Mint a new squirrelscan API key for this organization (requires credentials carrying the keys:write scope, which OAuth sign-in grants). The key is returned EXACTLY ONCE: show it to the user immediately and suggest saving it as the SQUIRRELSCAN_API_KEY environment variable for the CLI, CI, and MCP. Minted keys cannot themselves mint keys.
Takes no parameters.
Example callreturns →
Report your experience using squirrelscan mid-session: a bug, a missing feature, what worked, what confused you, missing report data, or tool ergonomics. Reviewed by the team to improve the product — use it any time something surprises you, not just at the end of a session. Works with any authenticated credentials, including read-only API keys.
Takes no parameters.

—Grade not published
No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is a hosted endpoint: the publisher runs it and we connect to it. The scanner reads packages and source, and neither exists to read here, so there is no grade — not a withheld one, an unmeasured one. What can be checked instead is on Installation: what it asks to reach and what it writes.

Reviews are earned
Writing one takes an account with at least 50 real tool calls against squirrelscan in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes an account with 50 real tool calls against it.
