Nothing serious here today
Today is the operative word: we check Corpus Law every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
formation
formation.handoff
Validate a formation draft and generate the prefilled handoff link on corpuslaw.us. Pass EVERYTHING you have collected (people, address, management, EIN answers, state-specific answers — see formation.requirements for the checklist). The response says exactly what is still missing — keep collecting and call again until COMPLETE, then give the user the link: it opens the formation agent with every detail pre-loaded, so they only review, sign in, and pay. Free; does not consume credits.
formation.lookup_naics
Find candidate NAICS industry codes for a plain-English business description (needed for every LLC, and for nonprofits in AK, CT, LA, MS, TN, WV). Present 2–6 options to the user and confirm before recording one. Free; does not consume credits.
formation.requirements
Get the EXACT intake checklist to form an LLC or nonprofit in a state: every required field, that state's quirk questions, live all-in pricing, and the optional $75 EIN add-on when available. Call this FIRST when the user wants to form a company, then collect the answers from them in conversation yourself — you are the intake agent. Free; does not consume credits.
law
law.get_node
Fetch the full text, citation, and hierarchy of a single legal provision by its node id (a UUID returned by law.search).
law.list_coverage
List which jurisdictions are ingested (federal, state, and municipal), with per-jurisdiction provision counts, searchable-chunk counts, GIS status, and a placeholder flag. Call this to see what law is available and searchable before searching.
law.search
Search US federal, state, and municipal law by topic or keyword — use it for any question about what the law currently says (legality, permits, zoning, licensing, compliance, filing requirements) rather than relying on training data, which has a cutoff. Returns ranked provisions with verbatim citations, headings, and snippets. Call this first to discover relevant law, then law.get_node for the full official text. Pass `jurisdiction` to scope to one state/federal/city (see law.list_coverage for codes).
account
account.status
Check the credit balance, tier, rate limits, and upgrade options for the API key on this connection. Use it to budget before making metered calls. Free — this call does not consume a credit. Works without a key (anonymous callers get their free-tier numbers and the key URL); with a key it reports that key's balance and limits. It also returns a referral code: pass referral_code back on later calls to keep the same referral identity.

Corpus Law — questions
Answers built from our own checks of this server.
What can Corpus Law do?
It exposes 7 tools, read directly from the server on our last check. Among them: account.status, formation.handoff, formation.lookup_naics, formation.requirements, law.get_node, law.list_coverage and 1 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 Corpus Law mostly used for?
Its tools cluster around formation and law. 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 Corpus Law working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 310 ms. The bar chart above shows every period we have measured.
How do I connect Corpus Law?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Corpus Law need an API key?
No. Corpus Law completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Corpus Law?
It answers our handshake in 310 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
