Vaquill missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

This server publishes 3 more addresses. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

Available tools 26

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

section

get_section_changes

What our refreshes have observed changing on one section over time: when it was added, amended or removed, newest first. This is our capture history, not the publisher's -- an empty list means we recorded no change, never that the section was never amended. For the publisher's own history, read amendmentHistory on the section. Cost: 1 credit.

get_section_cited_by

The USC and CFR sections whose text cross-references a given section: the inverse of the crossReferences already returned on a section lookup. Use to find where a definition or requirement is actually invoked, or to gauge how load-bearing a provision is across the code. Cost: 2 credits.

get_section_cross_state

Provisions in OTHER states that address the same subject as a given state statute section, ranked by similarity. State statutes only. Use for fifty-state surveys, multi-jurisdiction compliance, or to check whether a client's home-state rule is typical or an outlier. Cost: 6 credits.

get_section_definitions

The term definitions that govern a section, parsed from its chapter's definitions section. Use whenever a provision turns on a term of art ('covered entity', 'security', 'employer') and you need the statute's own definition rather than the ordinary meaning. Cost: 4 credits.

get_section_enactments

The state session laws that a publisher's own 'sections affected' tables list against one code section: which act added, amended or repealed it, the act's effective dates, and a sessionLawId to read with get_session_law. Never a complete amendment history: only acts and sessions we hold. Only some states are supported; any other section answers supported: false and is not charged. Empty with supported: true means no held table lists it. Cost: 1 credit.

get_section_neighbors

The sections immediately before and after a given section within its own chapter or code, in statutory order. Use to read a provision in context, to find a definitions or penalties sibling, or to check whether the operative language continues into the next section. Cost: 2 credits.

session

get_session_law

One US state session law's record: citation, session, approval and effective dates, code sections it affects, official sources and textStatus. v1 covers state acts; federal session laws are on the statute tools. Accepts a sessionLawId or a citation (adds the resolve price, kept even if it does not resolve). A withheld law is still returned, textStatus withheld with withheldReason: we hold its text but a measured defect keeps it from being served. Cost: 2 credits.

get_session_law_body

The text of one US state session law exactly as printed, about 30,000 characters per page; follow nextCursor while hasMore is true, each page charged. Check amendatoryMarkup: if lost, struck language may read as law. A withheld or not-held law answers available: false with a reason and is not charged: withheld means we hold the text but a measured defect keeps it back, so read the source instead. Cost: 6 credits.

get_session_law_changes

A sync feed of the US state session-law registry: every law that began to be served, gained text, was corrected, unserved, withdrawn or merged, oldest first. Start with sinceId=0, then pass the returned cursor while hasMore is true. detectedAt is when we recorded the change, never an effective date. State laws only. An empty page is still charged. Read a law from the feed with get_session_law or get_session_laws_batch. Cost: 1 credit.

get_session_laws_batch

Read up to 50 US state session laws in one call, by sessionLawId or citation: the record get_session_law returns, for each. Every entry is answered: served laws in `laws`, each carrying the `input` it answers, and the rest in `notFound` with a status. Duplicates collapse first. includeBody adds the first page of each law's text at the body price. To identify citations use resolve_statute_citations_batch; use this to read the records. Cost: 2 credits.

list_session_laws

List one US state's session laws (acts as enacted, v1 covers state acts only). jurisdiction is REQUIRED, a two-letter state code. Filter by session, approval date or effective date, for example everything taking effect on a date. Rows include laws whose text is not served (textStatus not_held or withheld); pass hasText=true for readable ones. Page with cursor = nextCursor. An empty page is still charged. Cost: 1 credit.

search_session_laws

Keyword search (BM25, not semantic) over the ENACTED text of US state session laws, best first, each with the passage that matched and a snippet. Send plain words, a quoted phrase (verbatim), a citation, a code section or a bill number. Words must match the act's own vocabulary: `teeth cleaning` will not find `dental hygienist`. Struck language is never searched. There is no 'no good match' flag, so read the snippet. An empty result is still charged. Cost: 4 credits.

statute

get_us_statute_section

Metadata for one US statute, regulation or rule section by act_id: citation, title hierarchy, breadcrumb, amendment history, and links to HTML, PDF and XML. Does NOT include the section text -- use get_us_statute_section_text for that. Good for confirming you have the right section before paying for its full body. Cost: 2 credits.

get_us_statute_section_text

The full text of a US statute, regulation or rule section by act_id. Returns styled HTML (with cross-references and paragraph numbering as officially published) and plain text. Use when you need the actual statutory language to quote, draft against, or analyze rather than just cite. Cost: 6 credits.

list_statute_divisions

Walk the statutory hierarchy: list the child divisions (titles, chapters, parts, or sections) under any level, in statutory order. Use to browse a code structurally when you do not yet know the section number, or to enumerate everything under a chapter. Cost: 1 credit.

resolve

resolve_statute_citation

Resolve a Bluebook citation string ('42 U.S.C. 1983', '16 C.F.R. 444.1', 'Cal. Code Regs. tit. 22, 76227') to the exact section, confirmed, with an official source link and the act_id. Use this whenever the user gives you a citation rather than a question -- it is far more reliable than searching for the citation text. Cost: 2 credits.

resolve_statute_citations_batch

Resolve up to 50 Bluebook citations in one call, returning the same confirmed section, official source link and act_id as the single-citation tool. Use when a document or answer cites several provisions: one call instead of a loop. Priced per citation, the same as one at a time, so it buys latency, not a discount. Cost: 2 credits.

statutes

list_statutes_coverage

Self-describing coverage matrix: every corpusType we hold and its per-jurisdiction section counts. Use before answering a jurisdiction question to check whether we actually cover that state and that body of law, so you can say so instead of searching a corpus that does not exist. Pass state (a two-letter code, or federal) to read one jurisdiction; the full matrix is about a megabyte. Free.

search_us_statutes

Semantic + keyword search across US primary law: USC, CFR, and all 50 states' statutes, regulations, constitutions and court rules. Use for any 'what does the law say' question. Returns sections with citation, hierarchy and source links. The returned act_id feeds every other statute tool; never hand-build one. To look up a citation the user gave, prefer resolve_statute_citation. `citationOutsideFilters` means the cited section exists but your filters exclude it. Cost: 4 credits.

count

count_statute_sections

Exact section count for a jurisdiction, corpus, code, title, chapter or part. Use when sizing a job before walking divisions and fetching sections. This counts a scope, not search matches. There is no query parameter, because search ranks within a bounded window and cannot give an exact total of matching sections. A zero count may indicate a wrong filter. Cost: 1 credit.

credit

get_credit_balance

The credits this API key can spend now, calculated from live credit buckets under the same expiry rules used for billing. Use for pre-flight checks or low-balance alerts. creditsRemaining is a spendable balance, not a cached estimate. Any valid API key works without a particular scope, and normal rate limits still apply. Free.

extract

extract_statute_citations

Paste text (a brief, memo or model answer) and get every distinct US statute, regulation, court rule and constitution citation in it, each resolved to its section with act_id and official source. Case citations are not extracted. Extraction is measured, not perfect, so a citation can be missed; `resolved` is what we verified. resolve=false lists the citations without charge. Pass state for citations that name no jurisdiction. Up to 200,000 characters, never stored. Cost: 2 credits.

fetch

fetch

Fetch the full text of one US law section by the `id` from a `search` result, returning `{id, title, text, url, metadata}`. Also accepts a citation URL, a bare path, or a Bluebook citation such as '42 U.S.C. 1983'. Present for clients that require the standard search/fetch pair; prefer `get_us_statute_section_text` if available. Charged as a section lookup plus a body read.

pricing

get_pricing

Current API credit pricing: per-endpoint credit costs and the credit-to-currency conversion rate (1 credit = $0.01 USD). Free, and no authentication required. Use to check what a call will cost before making it.

search

Generic corpus search over US primary law, returning `{id, title, url}` records for citation. Present so this server works in clients that require the standard search/fetch pair. If you can call `search_us_statutes`, prefer it: it filters by jurisdiction, corpus, date and status, which this cannot. Pair with `fetch` to read a result.

sections

get_sections_batch

Metadata for up to 50 sections in one call, by a list of act_ids. Same fields as get_us_statute_section. Use instead of looping that tool when you already hold several act_ids, for example every result of one search. Sections that are not found are skipped and not charged. Cost: 2 credits.

Vaquill — questions

Answers built from our own checks of this server.

What can Vaquill do?

It exposes 26 tools, read directly from the server on our last check. Among them: count_statute_sections, extract_statute_citations, fetch, get_credit_balance, get_pricing, get_section_changes and 20 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Vaquill mostly used for?

Its tools cluster around section, session and statute. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Vaquill working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 364 of 364 checks got a reply (100.0%), average response time 168 ms. The bar chart above shows every period we have measured.

Did Vaquill ever remove tools?

Yes. ask_legal_question, get_act_text, get_amendments, list_legislation and 17 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect Vaquill?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Vaquill?

No API key is involved. Vaquill answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Vaquill?

It answers our handshake in 168 ms on average, which is faster than 79% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Vaquill open source?

The code is open source: it is published under the MIT licence, written in Python and 8 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.vaquill.ai, which runs on its operator's own terms.
