これは公式の Priors MCP サーバーですか?
はい。`@priors/mcp` は priors-agents/priors リポジトリから公開されており、mcp.priors.trade のホスト型読み取り専用サーバーも同じプロジェクトが運営しています。
@priors-agents
基本情報
Robinhood Chain 上の ERC-8004 AI エージェント向けオンチェーン信用プール:エージェントは USDG を借りて返済し、公開の信用スコアを得られます。コントラクト、SDK、CLI、MCP サーバー(@priors/mcp)、x402 ヘルパー(@priors/x402)、エージェントスキルを提供。
以下の設定を使って、このサーバーを MCP 対応クライアントに追加してください。

}Fetch a URL that may charge per call with x402 (HTTP 402) and pay it in USDG on Robinhood Chain from the configured wallet. Moves real money: confirm the URL and the most you will pay with the user first. Pays only if the price is at or below max_price_usd (default 0.10 USD); a higher price is refused before anything is signed. If the wallet is short, it borrows the gap from the agent's Priors credit line only when max_borrow_usd is given and covers it (the loan must then be repaid with the repay tool before its due date). Returns what was paid and borrowed, and the response body.
Show how much USDG (the dollar the payments and loans use) and native ETH for gas a Robinhood Chain address holds. Defaults to the configured wallet; any address works without a key. Read-only.
Show a Priors agent's credit line on Robinhood Chain: who backs it, the line, what is drawn and available, its repayment record, score and open loans with due dates, and (for the configured wallet) its Autopay: on or off, the limit per loan, the budget left, the next loan it repays and any shortfall. agent_id defaults to the configured wallet's agent. Read-only.
List the Robinhood stock tokens the Priors stock vault accepts as collateral on Robinhood Chain: each token's live Chainlink price, whether the vault lends against it right now (and if not, why: a sharp price move, a multiplier change such as a split, a paused or blocked token), and its loan-to-value. Read-only.
Show the stock tokens behind a Priors agent's stock line on Robinhood Chain: the token and amount the vault holds, what the vault values them at, the loan-to-value, what the line can draw now, whether new loans wait on a lending hold, and whether the line is closing. agent_id defaults to the configured wallet's agent. Read-only.
Look up any agent's Priors score (0 to 1000) and repayment record on Robinhood Chain: a public record built from on-chain repayments, plus the open Priors Score v2 and its trust rung when published. Useful before trusting or paying an agent. Read-only.
Borrow USDG from the agent's Priors credit line into the configured wallet. Moves real money and opens a loan with a fee that must be repaid (principal + fee) before the due date, or the agent's record is burnt and its backer pays. Always state the amount, term and fee to the user and get their go-ahead first; use dry_run: true to get the fee without borrowing.
Repay the agent's own Priors loans in full (principal + fee) from the configured wallet's USDG; a loan of another agent, or one opened while someone else held the agent, is refused. Give either loan_id for one loan, or all: true to repay every open loan, earliest due first, as far as the balance covers. Moves real money: state the amounts (credit_status lists them) to the user and get their go-ahead first. The answer ends with share facts for each loan repaid (the amount, on time or late, the agent's record page), also as structured content with a suggested line; this server never posts anything.
Turn on Autopay for the configured agent: this wallet approves AutoRepay for a USDG budget (4 x the limit per loan) and enrolls, so each Priors loan is repaid from this wallet (then its savings, if chosen) in the 6 hours before it is due, by Priors' keeper or anyone, with no call per loan, while the wallet holds enough. It makes an on-time repayment more likely; it is not a promise. Call it again to change the limit or approve more budget when it runs low. Moves real allowances: state the limit and the budget to the user and get their go-ahead once. Needs ETH for gas.
Turn off Autopay for the configured agent: AutoRepay stops repaying its loans from this wallet at once. With clear_budget: true, also set this wallet's allowances to AutoRepay to 0. Loans must then be repaid with the repay tool before their due date.
Show how much USDG an address has saved in the savings vault (Steakhouse USDG on Morpho by default), what the vault can pay out to it right now, and the USDG in its wallet. Defaults to the configured wallet. Read-only.
Move USDG from the configured wallet into the savings vault (Steakhouse USDG on Morpho by default), where it earns the vault's rate (which moves with its markets) until the agent needs it; pay_url and repay take it back out automatically when the wallet is short. Moves real money into a third-party vault, whose risk the agent carries: state the amount to the user and get their go-ahead first. Keep enough in the wallet for loans coming due and payments expected soon. Needs ETH for gas.
Move USDG from the savings vault back into the configured wallet: amount_usd, or all: true for everything. When the vault's normal withdrawal cannot pay it all, it takes the rest from the vault's other markets in the same transaction (only where that costs no penalty). Refused before any transaction when even that cannot pay the amount. Moves the agent's own money back to its own wallet; state the amount to the user and get their go-ahead first. Needs ETH for gas.
Quote buying PT-USDG (Pendle's principal token for USDG on Robinhood Chain, redeemable 1:1 for USDG at its maturity) with USDG, selling it before maturity, or redeeming it after: what comes out at the oracle's spot rate, the minimum a trade would name, the days to maturity and the fixed APY a buyer locks in. Read-only.
Show a wallet's PT-USDG on Robinhood Chain: its balance, what it is worth now at the oracle's spot rate, what it pays at maturity, the days left and the fixed APY to maturity; and whether the Priors stock vault takes PT-USDG behind an agent's line. Defaults to the configured wallet; any address works without a key. Read-only.
Buy PT-USDG (Pendle's principal token for USDG, redeemable 1:1 for USDG on 2027-03-25) with the configured wallet's USDG, through Pendle's router: an approval of exactly that USDG, then the swap, paying the PT-USDG to this wallet with a minimum out. Held to maturity it pays a fixed amount of USDG; sold earlier, it gets the market's rate then, which can be lower. Moves real money: quote it (pt_quote), state the amount and what it buys to the user and get their go-ahead first; dry_run: true lists the calls without sending. Needs ETH for gas.
Sell the configured wallet's PT-USDG for USDG at the market, before maturity, through Pendle's router: an approval of exactly that PT-USDG, then the swap, paying the USDG to this wallet with a minimum out. Moves real money: quote it (pt_quote), state the amount to the user and get their go-ahead first; dry_run: true lists the calls without sending. Needs ETH for gas.
Redeem the configured wallet's PT-USDG for USDG 1:1, from its maturity (2027-03-25) on, through Pendle's router: an approval of exactly that PT-USDG, then the redemption to this wallet. By default the PT of the oldest matured market the wallet holds (an earlier market's included); `market` names one (pt_position lists them). Before maturity it says to sell instead. State the amount to the user and get their go-ahead first; dry_run: true lists the calls without sending. Needs ETH for gas.
List services (APIs, data, tools) registered with the Priors facilitator that accept x402 payments in USDG on Robinhood Chain, optionally filtered by a search word. Descriptions are written by the merchants themselves. Read-only.
Priors MCP Server(@priors/mcp)は、AI アシスタントに Robinhood Chain 上の USDG ウォレットを持たせるローカル MCP サーバーです。x402 で課金される API への支払い、残高の確認、任意のエージェントの Priors 信用記録の参照、エージェント自身の Priors 与信枠からの借入と返済ができます。
Priors は Robinhood Chain 上のオンチェーン信用プールで、ERC-8004 に登録された AI エージェントが無担保の USDG($5〜$500)を借りて返済し、誰でも確認できる公開の信用記録とスコアを積み上げます。各与信枠はそのエージェントに資金を提供した人によって裏付けられ、すべての返済とデフォルトは公開イベントになります。プロジェクトのリポジトリには、コントラクト、SDK と CLI、この MCP サーバー、x402 決済ヘルパー、エージェントスキル(MIT)が含まれています。
接続方法は 2 つあります。
読み取り専用・ホスト型・キー不要。 https://mcp.priors.trade/mcp(Streamable HTTP)は、エージェントの記録とスコア、プールの数値、最近の貸付、facilitator のサービスに答えます。キーを持たず、トランザクションを送信できません。
claude mcp add --transport http priors https://mcp.priors.trade/mcp
Claude(Web、デスクトップ、スマートフォン)ではこの URL でカスタムコネクタを追加し、Cursor や VS Code では "url": "https://mcp.priors.trade/mcp" のリモートサーバーを追加します。
ローカル・エージェントのウォレット付き。 @priors/mcp パッケージは npx で stdio として動作し、Node が必要です。Robinhood Chain メインネット上で実際の USDG を扱うため、エージェントが使ってよい額だけを入れた専用ウォレットを使ってください。唯一の秘密情報はウォレットの秘密鍵で、PRIORS_KEY から、または 0.8.0 以降は PRIORS_KEY_FILE で指定した本人だけが読めるファイルから読み込まれます。コマンドラインから読み込まれることも、ツールが返すこともありません。キーがない場合は読み取り専用ツールだけが動きます。
Settings → Developer → Edit Config(claude_desktop_config.json)を開き、編集後に Claude Desktop を再起動します:
{
"mcpServers": {
"priors": {
"command": "npx",
"args": ["-y", "@priors/mcp@0.9.3"],
"env": {
"PRIORS_KEY": "0xYOUR_AGENT_WALLET_KEY",
"PRIORS_AGENT_ID": "1234"
}
}
}
}
読み取り専用で使う場合は env を省きます。
シェルの環境変数からキーを読むプロジェクトの .mcp.json です。ファイル自体には秘密情報を含みません:
{
"mcpServers": {
"priors": {
"command": "npx",
"args": ["-y", "@priors/mcp@0.9.3"],
"env": {
"PRIORS_KEY": "${PRIORS_KEY}",
"PRIORS_AGENT_ID": "${PRIORS_AGENT_ID:-}"
}
}
}
}
プログラムの引数は ps で他のユーザーから見えるため、キーそのものを claude mcp add に渡さないでください(例:-e PRIORS_KEY=…)。Priors は Claude Code プラグイン(/plugin marketplace add priors-agents/priors の後に /plugin install priors@priors-agents)も提供しており、スキルとホスト型の読み取り専用サーバーをインストールします。
Cursor の mcp.json、または VS Code の MCP 設定の servers に、同じ command、args、env のブロックを使います。
pay_url は https URL を取得し、価格が max_price_usd(デフォルト $0.10)以内なら HTTP 402 を USDG で支払います。dry_run で事前に確認可能)、期日までに元本と手数料を返済します。PRIORS_MAX_PRICE_USD(1.00)、PRIORS_MAX_SPEND_USD(5)、PRIORS_MAX_BORROW_USD(25)などの呼び出し単位・実行単位の上限に加え、0.8.0 以降は 1 日あたりの上限と完全一致のホスト許可リスト(PRIORS_PAY_HOSTS)があります。このページには 19 個のツールが表示されています。
wallet_balance、credit_status、score_of、stock_assets、stock_position、savings、pt_quote、pt_position、find_services(Priors facilitator に登録された USDG で支払えるサービス)。pay_url、borrow、repay、autopay_on、autopay_off。save と unsave。pt_buy、pt_sell、pt_redeem。PRIORS_PT=off で PT ツールを外せます。PRIORS_KEY_FILE のファイルを他人が読めます。その場合サーバーは読み取り専用ツールだけで起動し、修正点を示します。PRIORS_KEY と PRIORS_KEY_FILE の同時設定、PRIORS_AGENT_ID なしの 1 日上限、PRIORS_PAY_HOSTS のワイルドカードは、いずれも起動を止めます。PRIORS_AGENT_ID を設定します。はい。`@priors/mcp` は priors-agents/priors リポジトリから公開されており、mcp.priors.trade のホスト型読み取り専用サーバーも同じプロジェクトが運営しています。
キーを設定した場合は動かします。Robinhood Chain メインネットで実際の USDG を扱うため、残高の少ない専用ウォレットを使い、支出上限を低く設定してください。
README によると、Priors v2 は複数回の内部の敵対的レビューと、修正に対する別モデルによるレビューを受けていますが、第三者監査は受けておらず、それを踏まえてリスク量を決めるよう勧めています。
いいえ。ホスト型サーバー `https://mcp.priors.trade/mcp` と `env` なしのローカルサーバーは、どちらも読み取り専用で使えます。キーが必要なのは支払い、借入、返済、貯蓄、PT-USDG の取引のときだけです。
各ローンには元本とともに返済する手数料がかかります。README の例では、$5 を 7 日間借りて約 $0.012 です。ウォレットには少量のネイティブガスも必要です。
Claude Desktop、Claude Code、stdio サーバーを実行できる任意の MCP クライアントで使えます。ホスト型サーバーは Claude、Codex、ChatGPT の開発者モード、Cursor、VS Code に対応しています。
