Escrow protection for agent payments on Base — USDC held in smart contract until job completion.

已验证Streamable HTTP可网页运行金融

概览

AI 生成的概览

让助手在 Base 上发起并释放由智能合约托管的 USDC 付款，直到任务完成。

可以做什么
Paycrow 为智能体付款提供托管保护：USDC 由智能合约持有，直到任务完成后再释放，运行在 Base 网络上。它既提供远程端点，也提供通过 stdio 运行的本地 npm 包。未公布工具列表，因此具体操作在此无法说明。
适用场景
当助手需要为他人完成的工作付款，并希望资金在完成前被锁定而不是预先支付时，可以考虑使用。对于不需要托管的普通付款没有帮助。
运行要求
需要连接远程端点，或在本机安装 Node.js 运行时以通过 stdio 运行该 npm 包。未声明任何身份验证、环境变量或请求头。
安装前请注意
它会在 Base 上转移真实 USDC，资金可能因合约逻辑被支出或锁定。未声明身份验证，工具列表也未公布，因此在让助手释放付款前应审查合约与实际工具。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Paycrow，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.michu5696%2Fpaycrow/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

工具

10

trust_gate

Should you pay this agent? Check before sending money. Returns a go/no-go decision with recommended escrow protection parameters. Unlike other trust services, PayCrow ties trust directly to escrow protection: - High trust → shorter timelock, proceed with confidence - Low trust → longer timelock, smaller amounts recommended - Caution → don't proceed, or use maximum protection This is the tool to call BEFORE escrow_create or safe_pay.

输入参数address必填intended_amount_usdc

trust_score_query

Full trust score breakdown for an agent address. Aggregates 4 on-chain sources: PayCrow escrow history, ERC-8004 agent identity, Moltbook social karma, and Base chain activity. Returns 0-100 score with per-source details. For a quick go/no-go decision, use trust_gate instead.

输入参数address必填

trust_onchain_quick

Quick on-chain reputation check using only the PayCrow Reputation contract. Free, no API keys needed. Use trust_score_query for the full composite score.

输入参数address必填

escrow_create

Create a USDC escrow with built-in dispute resolution. Funds are locked on-chain until delivery is confirmed (release) or a problem is flagged (dispute). If disputed, an arbiter reviews and rules — the only escrow service with real dispute resolution on Base.

escrow_release

Confirm delivery and release escrowed USDC to the seller. Only call this when you've verified the service/product was delivered correctly.

输入参数escrow_id必填

escrow_dispute

Flag a problem with delivery — PayCrow's key differentiator. Locks escrowed funds and triggers arbiter review. Unlike other escrow services that say 'no disputes, no chargebacks', PayCrow has real on-chain dispute resolution. Use when service was not delivered or quality was unacceptable.

输入参数reason必填escrow_id必填

escrow_status

Check the current state of an escrow (funded, released, disputed, expired, etc.)

输入参数escrow_id必填

rate_service

Rate a completed escrow. After escrow_release, rate the seller's service quality (1-5 stars). This builds the reputation data that makes PayCrow's trust scores meaningful over time. Both sides can rate: buyer rates seller's service quality, seller rates buyer's conduct. Ratings are on-chain and permanent — they feed directly into trust scoring.

输入参数stars必填escrow_id必填

safe_pay

The smart way to pay an agent. Checks their trust score first, then auto-configures escrow protection based on risk. Flow: Check trust → Set protection level → Create escrow → Call API → Verify → Auto-release or auto-dispute. Protection levels (automatic): - High trust agent → 15min timelock, proceed normally - Moderate trust → 60min timelock, payment capped at $25 - Low trust → 4hr timelock, payment capped at $5 - Unknown/caution → BLOCKED — will not send funds This is the recommended tool for paying any agent. If you need manual control, use x402_protected_call instead.

x402_protected_call

Make an HTTP API call with manual escrow protection. Full control over verification and timelock parameters. For most payments, use safe_pay instead — it auto-configures protection based on seller trust. Use x402_protected_call when you need: - Custom JSON Schema verification (not just "valid JSON + 2xx") - Hash-lock verification (exact response match) - Specific timelock durations - To override safe_pay's trust-based amount limits
