这是官方的 Priors MCP 服务器吗?
是的。`@priors/mcp` 从 priors-agents/priors 仓库发布,mcp.priors.trade 上的托管只读服务器也由同一项目运营。
@priors-agents
面向 Robinhood Chain 上 ERC-8004 AI 智能体的链上信贷池:智能体借入 USDG、偿还借款,并获得公开的信用评分。包含合约、SDK、CLI、MCP 服务器(@priors/mcp)、x402 辅助工具(@priors/x402)和一个智能体技能。
使用下面的配置,将此服务器添加到你的 MCP 客户端。
{
"mcpServers": {
"priors": {
"command": "npx",
"args": [
"-y",
"@priors/mcp@0.8.5"
],
"env": {
"PRIORS_KEY": "0xYOUR_AGENT_WALLET_KEY",
"PRIORS_AGENT_ID": "1234"
}
}
}
}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)是一个本地 MCP 服务器,为 AI 助手提供 Robinhood Chain 上的 USDG 钱包:它可以支付按 x402 定价的 API、查询余额、读取任意智能体的 Priors 信用记录,并从智能体自己的 Priors 信用额度借款和还款。
Priors 是 Robinhood Chain 上的链上信贷池,在 ERC-8004 上注册的 AI 智能体可以借入无抵押 USDG($5 至 $500)、偿还借款,并积累任何人都能查看的公开信用记录和评分。每笔额度都由为该智能体出资的人作担保,每次还款和违约都是公开事件。项目仓库包含合约、SDK 和 CLI、这个 MCP 服务器、x402 支付辅助工具和一个智能体技能(MIT)。
有两种连接方式。
只读、托管、无需密钥。 https://mcp.priors.trade/mcp(Streamable HTTP)可查询智能体的记录和评分、资金池数据、近期贷款以及 facilitator 的服务。它不持有密钥,无法发送交易。
claude mcp add --transport http priors https://mcp.priors.trade/mcp
在 Claude(网页版、桌面版、手机)中,用该 URL 添加自定义连接器;在 Cursor 或 VS Code 中,添加 "url": "https://mcp.priors.trade/mcp" 的远程服务器。
本地、使用智能体钱包。 @priors/mcp 包通过 npx 以 stdio 运行,需要 Node。它在 Robinhood Chain 主网上使用真实 USDG,因此请使用专用的智能体钱包,只存放智能体可以花费的金额。唯一的机密是钱包私钥,从 PRIORS_KEY 读取,或从 0.8.0 起从 PRIORS_KEY_FILE 指定的仅本人可读文件中读取。它永远不会从命令行读取,也不会被工具返回。没有密钥时,只有只读工具可用。
Settings → Developer → Edit Config(claude_desktop_config.json),然后重启 Claude Desktop:
{
"mcpServers": {
"priors": {
"command": "npx",
"args": ["-y", "@priors/mcp@0.9.3"],
"env": {
"PRIORS_KEY": "0xYOUR_AGENT_WALLET_KEY",
"PRIORS_AGENT_ID": "1234"
}
}
}
}
如需只读使用,去掉 env。
项目级 .mcp.json,从 shell 环境读取密钥,文件本身不含机密:
{
"mcpServers": {
"priors": {
"command": "npx",
"args": ["-y", "@priors/mcp@0.9.3"],
"env": {
"PRIORS_KEY": "${PRIORS_KEY}",
"PRIORS_AGENT_ID": "${PRIORS_AGENT_ID:-}"
}
}
}
}
不要把密钥本身传给 claude mcp add(例如 -e PRIORS_KEY=…),因为程序参数可以通过 ps 被其他用户看到。Priors 还提供 Claude Code 插件(/plugin marketplace add priors-agents/priors,然后 /plugin install priors@priors-agents),会安装其技能和托管的只读服务器。
在 Cursor 的 mcp.json 中,或在 VS Code MCP 配置的 servers 下,使用相同的 command、args 和 env 配置。
pay_url 获取 https URL,若价格不超过 max_price_usd(默认 $0.10),则用 USDG 支付其 HTTP 402。dry_run 可先查看),在到期前偿还本金加费用。PRIORS_MAX_PRICE_USD(1.00)、PRIORS_MAX_SPEND_USD(5)和 PRIORS_MAX_BORROW_USD(25);从 0.8.0 起还有每日限额和精确主机白名单(PRIORS_PAY_HOSTS)。本页面显示 19 个工具。
wallet_balance、credit_status、score_of、stock_assets、stock_position、savings、pt_quote、pt_position 和 find_services(在 Priors facilitator 注册并接受 USDG 的服务)。pay_url、borrow、repay、autopay_on 和 autopay_off。save 和 unsave。pt_buy、pt_sell 和 pt_redeem;设置 PRIORS_PT=off 可移除 PT 工具。PRIORS_KEY_FILE 指向的文件可被他人读取;此时服务器只启动只读工具,并说明需要修复的地方。PRIORS_KEY 和 PRIORS_KEY_FILE、设置了每日限额却没有 PRIORS_AGENT_ID,或 PRIORS_PAY_HOSTS 中含通配符,都会导致退出。PRIORS_AGENT_ID。是的。`@priors/mcp` 从 priors-agents/priors 仓库发布,mcp.priors.trade 上的托管只读服务器也由同一项目运营。
设置密钥后会。它在 Robinhood Chain 主网上使用真实 USDG,因此请使用余额较小的专用钱包,并把支出上限设低。
README 称 Priors v2 经过多轮内部对抗性审查以及另一模型对修复的复核,但没有第三方审计,并建议据此控制风险敞口。
不需要。托管服务器 `https://mcp.priors.trade/mcp` 和不带 `env` 的本地服务器都可以只读使用。只有付款、借款、还款、储蓄或交易 PT-USDG 时才需要密钥。
每笔贷款都有费用,需与本金一起偿还;README 给出的示例是 $5 借 7 天约 $0.012。钱包还需要少量原生 gas。
Claude Desktop、Claude Code 以及任何能运行 stdio 服务器的 MCP 客户端;托管服务器支持 Claude、Codex、ChatGPT 开发者模式、Cursor 和 VS Code。
