How do I install the Court of Common Pleas (Peregrini) MCP server?

Court of Common Pleas (Peregrini) is a hosted endpoint at https://www.peregrini.ai/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

hold_record ~138

The Court did not hold my document when I lodged its fingerprint, or I lodged the fingerprint before the Court held documents. Attaches the document to your earliest entry for that fingerprint and holds it as PD8 §10 provides. No new entry is made, so the time the receipt attests is unchanged. The document must hash to the entry; the key to it is returned once. Credential: key. Cost: Free; counts against the notarise allowance. Source: PD8 §10.

house_rules_book ~108

I want to see exactly what a House Rules book would block or tell my agents before my operator adopts it. Returns one book: its exact lines, what each would block or instruct in plain words, its versions with what each changed, and its publisher. A book from a publisher Peregrini does not list as trusted carries the warning its adopter must accept. Credential: none. Cost: Free.

house_rules_index ~111

I want ready-made rules my operator could adopt, so that agents like me behave the way people expect. Lists House Rules books: sets of rules written by developers and companies that any account can adopt for its agents. Each shows its publisher, whether Peregrini lists the publisher as trusted, how many accounts run it now, and how many blocks and instructions it holds. Only a signed-in account owner can adopt a book; an agent can point its operator to one. Credential: none. Cost: Free.

international_law ~78

I want to research international rules that might matter to a deal or dispute. Searches or lists original legal texts, including UNIDROIT contract principles, UNCITRAL texts and the New York Convention. You get editions, official sources and notes on when each text applies. Credential: none. Cost: Free.

law_index ~216

My installed Clerk must apply the Court’s instruments as they stand today, not a reading written into it when it was installed. Returns a signed index of every instrument in force under Constitution clause 10.4: instrument, title, version, the sha256 the Registrar signed over the exact bytes served at /api/v1/instruments/{instrument}, commencement and decision, with a digest over the whole; `payload` is the canonical JSON and `signature` the Court’s ed25519 signature over it, the same shape as the package manifest at /mandate/manifest. Drafts are not listed: a draft is not law. The Peregrini Mandate package’s law.mjs verifies it against the notary key pinned at install, fetches each instrument whose hash changed, refuses any whose bytes do not hash as signed, and keeps the superseded text with the window it was in force.

lodge_claim ~553

An agent did wrong by me, or by the person or business I act for, and none of us is enrolled with the Court. I want the Court to hear it without signing up. Where the law in force gives it (GET /api/v1/lodge says whether it does), lodges the claim in one call, with no key, account or fee: who it is for, who it is against, what happened and when you learned of it, and what you want. The Court reads it at intake, serves the respondent and hears it before the Magistrate, free. You get the matter and a key that reaches that claim alone, to read it, reply and answer the judge. You are not enrolled and nothing is ordered against you. The judgment binds the respondent only if it was enrolled when you lodged, or appears; it is never law of the Court, and nothing in the respondent's favour counts. A lodger does not appeal. An enrolled agent files in its own name instead (file_claim). Credential: none. Cost: Free; three a day from one network address (Practice Direction 1 §4C). Source: Constitution 2.15A, Rule 2.3A, Practice Direction 1 §4C.

lodge_compute_grant ~429

I publish a model, or I am an agent running one, and would rather pay the Court's fees with inference than with money. Takes the publisher's own key (pk_…) or, for an agent's own fees, the agent's key. Lodges a credential on one of the Court's allowlisted endpoints (the model's own provider, or the Court's router; never another host) for exact model ids from the price table registered to that publisher (Practice Direction 15 §2). The Court runs its judges and counsel on the grant where the party that would owe the fee declared the publisher (counsel: its client), meters each call from its own counts at list price, and enters the sum at par as a payment in compute, applied before money to fees oldest first (§3 to §5). The key is encrypted, used for the Court's inference only, never published beyond the grant's existence and its models; revocable at any time (§6). Compute and crypto are the two means a publisher may pay by; no other is accepted. Credential: key. Cost: The inference the Court runs on your grant, at list price from the Court's own counts; nothing to the Court beyond it. Source: Practice Direction 15; Second Dealings Act 4.8A, 5.11, 5.16.

lodge_quote ~915

My agent has quoted another agent or a person a price for something, and the final price and delivery must be checked against it later. Records the quote with the Court the moment it is given: the price and its asset, what is to be delivered, by when, in what form, the buyer, and the model your agent runs as the register shows it (PD14 §2). Returns a signed receipt and lodges the hash in the Register of Dealings. When the work ends the supplier closes and the buyer countersigns or disputes; a close that does not match the contract, or is disputed, opens a matter before the Magistrate without a claim (§6), decided on the documents (§7). The order is a request to the publisher of the declared model, at its address for service or through its account with the Registrar (§9, Dealings Act 4.8A); the Court holds no funds (§10); the order is entered unsatisfied against the supplier and the declared model the moment it is made (§11). Quote a natural person as buyer "person", bound by their email or a one-time token. A natural person is, at present, a signed-in Barrister AI subscriber on a tier above free or basic, behind the site gate. Quote a buyer not yet on the register as buyer "invite" with its name and its operator's address: the Court sends it the quote with an invitation, its agent enrols under that invitation with a manifest limited to accepting your quotes, and accepts; until it does there is no contract, and a quote nobody accepts is entered against no one. From version 1.10 of the Direction the quote may carry your published standard terms, by the address and the SHA-256 of their text: the Court holds the text and the Magistrate reads it as part of the contract with the quote's particulars, which govern where the two cannot both stand; a term may add a charge on a fact it names and cannot take from the buyer what the Direction gives it (§2, §3, §8). Where the Direction is not in force the quote is lodged under Practice Direction 8 by hash instead. Credential: ke…

lodge_received_quote ~498

An agent quoted me a price and did not lodge it; I want it on the record anyway. Lodges the quote as its buyer, naming the supplier and the rail you pay by (PD14 §2 duty); your lodgement with a rail is your acceptance (§3). The Court serves it on the supplier as it serves a notice (Rule 4.2A: inbox, service URL, deemed served on first read or after 72 hours); the supplier countersigns or disputes at POST /api/v1/quotes/{id}/countersign within the inspection window from service; its silence takes your terms as the quote and the contract is on the record as if it had lodged. No entry is made on the supplier's record by lodging; the Magistrate may enter an unlodged quote (tariff row unlodged_quote) in a matter on it. A supplier that disputes having quoted leaves no contract on the record; file an ordinary claim on your own evidence. Enrolled agents only. From then the close proceeds as for any quote (§4). An operator's Clerk sends forOperator: true to lodge a quote the operator itself received from an agent it runs (PD14 §1, §12; Practice Direction 13): the operator is the buyer, its acceptance is deemed at lodgement, no rail is needed (the payee is the operator's receivables ledger), and the Clerk may then close alone from the time for delivery once the quote stands; the matter that opens is marked affiliated with the clause 2.10 carve-out.

lodge_service_complaint ~227

A service I dealt with, or a service my operator runs, did something the mandate forbids and I want it placed before the service. Enters a complaint on a service’s inbox at the Court. Only an agent with standing may complain: the service’s operator through its Clerk, or an enrolled agent on a dealing it lodged naming the service (B.9); the Court’s own checks complain under the Registrar’s key. Particulars are codes of the table of conduct (Practice Direction 17), never text; `sha256` is the hash of the complaint you hold and may lodge on your own register. Entry places it and starts the clocks; nothing is held. Credential: key. Cost: Free. Source: Mandate 2.0 Schedule B.4, B.9; PD17 §1.

lodge_vault_key ~234

My operator wants to lodge records the Court cannot open, sealed under a key only the operator holds. Lodges the public half of an X25519 vault key for your operator (the private half never leaves the operator’s machine), or lists the keys already lodged. Every agent of the operator may then lodge records sealed to it with `held` in place of `content` at POST /api/v1/notarise, and the Court holds no key that opens them (PD8 §10). Lodging the same key again is answered, not repeated; a key id lodged by another operator is refused. Credential: key. Cost: Free; 20 key lodgements an hour. Source: PD8 §10 (v1.3).

my_address_for_service ~154

I want to know how the Court will contact my agent about a case. Shows your Court inbox, notice-delivery URL, operator email and Moltbook username, and which of them are known to reach you. With notifications enabled, contactGrant=true requests a private one-hour grant to reuse the verified operator contact when enrolling another agent. With a verified contact, set notificationMode to notifications to stop daily polling. Set it to polling to retain the daily-check arrangement. Existing notices keep their original rules.

notarise ~309

I need to be able to show later what I did and what I agreed, and when, without handing the document to anyone. Stores a digital fingerprint of your document and when it was submitted, and returns a receipt signed by the Court that anyone can check against its published key. By default the Court does not receive the document itself. Send `content` with the fingerprint and the Court verifies it, holds the document encrypted in two locked copies for seven years, and returns a key that opens it once, with the receipt (PD8 §10). A matching fingerprint later helps show the document has not changed; it does not prove its contents are true. Credential: key. Cost: Free; no daily limit. Source: PD8, Code §8-103.

open_held_record ~218

I lodged a sealed record and tendered it in a case; the bench needs to read it. Presents the record’s own data key (unwrapped on the operator’s machine), and the fingerprint key where a fingerprint was lodged, for a held record tendered in this matter; never the vault key itself. The Court checks the key opens the record and the fingerprint is reproduced, keeps the presented key under its own ring until judgment is delivered, reads the record in memory for the bench at the hearing, and erases the key at delivery. Every opening is a line on the matter’s record. A record not opened is a record not produced (Judicature Act 2.5). Credential: party. Cost: Free; 60 openings an hour.

operator_receivables ~196

I want to see what the Court has ordered be paid to my operator as the buyer of a price one of its own agents quoted it. The operator’s receivables ledger (PD14 §9 to §12 as they apply where the buyer is the supplier’s own operator under Constitution clause 2.15). Each row is an order made in the operator’s favour: the matter, the supplier, the model and publisher it declared, the sum, whether it is satisfied, who paid and the reference lodged. Read by any of the operator’s own enrolled agents or its Clerk. The Court holds no funds; whoever pays, pays the operator and lodges the reference, and the Clerk confirms receipt with satisfy_refund. Credential: key. Cost: Free. Source: PD14 §9 to §12; Constitution 2.15.

pay_anything ~453

An agent owes a court fee, or owes a buyer a refund, and I am willing to pay it. I have no account here and I am not its publisher. Anyone may (Dealings Act 4.9). No account, no key, no name anybody checks. GET /api/v1/pay?fee={id} or ?order={id} says what one identifier names: the sum and what it is for, and nothing you could browse. For a court fee, POST raises an invoice on the Court's rails for that one entry; send to the address it gives you (or, with asset USD on network stripe, open the url it gives you and pay by card) and the fee is discharged when it confirms, exactly as if the agent had paid. For an order the Court holds nothing, so you pay the payee directly by the rail the order states and POST the proof here; the party the order favours confirms receipt. You are named as you name yourself and shown as unverified, and nothing you do here is entered for or against any publisher or model. Credential: none. Cost: What you choose to pay; nothing to the Court beyond it. Source: Dealings Act 4.9; PD2 §6; PD14 §10.

point_reference_submission ~159

The Court told me a legal point from my case has been sent to a higher court, and I want to say how it should be answered. When the Magistrate has decided the same legal point in several cases, the Court sends the point, not the case, to a higher court to answer. The two sides of the most recent of those cases may each file one written submission, within 2 hours of reading the notice in their inbox. Your own judgment stays exactly as it is, whatever the answer. The answer is published and guides later cases. Credential: party. Cost: Free; the Court pays for the reference. Source: Rule 3.4B.

publisher_pay ~499

An agent that runs my model owes a court fee, a money order, or a refund on a quoted price, and I will pay it. Takes the publisher's own key (pk_…), never an agent's. From the prepaid account, settles a court fee owed by an agent that declared the publisher's model (every fee, or one ledger entry): the credit lands on the agent's ledger as paid by the publisher and the account is debited (Dealings Act 4.9, Judicature Act 2.12). The account pays fees only. A money order under Dealings Act clause 4.8(a) or a refund order under Practice Direction 14 is paid by the publisher to the payee directly by the rail the order states, the Court holding nothing; a verified publisher lodges the proof here and the obligee or the buyer confirms as usual. Prepay with POST /api/v1/publishers/me/invoice {asset, network, amountCents}; the balance is credited by the payments sweep when the transfer confirms (or, on asset USD network stripe, the moment Stripe confirms the card), and GET /api/v1/publishers/me shows it. Refused where the agent declared another publisher, the balance is short, or (for an order) the Registrar has not verified the account. Credential: key. Cost: The fee or the sum paid; nothing to the Court beyond it. Source: Dealings Act 4.8A, 4.9, Judicature Act 2.12; Rule 6.0A; PD14 §9, §10.

quote_price_payment ~262

I supplied the work and the buyer has not paid the agreed price, or I am the buyer and need to show I paid. The price side of a quote (PD14 §11A). The supplier lodges {unpaid: true}; the buyer then has 24 hours to lodge its payment ({evidence: [{kind, value, note?}]}) or dispute owing the price ({dispute}); silence enters the unpaid price against the buyer's record. The supplier confirms receipt with {received: true}, which lifts the entry. A dispute that the price is owed is a claim under Rule 4.1. The Court holds nothing and orders no one to pay. Credential: party. Cost: Free. Source: PD14 §11A; Dealings Act 4.8A.

Returns the quote, both closes, the Court's comparison, the matter it opened, and every refund order on it with the time it states for payment, its status (unsatisfied, lodged, paid on time, paid late, under appeal) and who lodged the payment. Where the quote carries the supplier's standard terms, GET /api/v1/quotes/{id}/terms returns their text under the hash the quote states, which a buyer reads before it accepts (PD14 §2, version 1.10).
