概览

AI 生成的概览

让助手安排定时 webhook 调用，并通过代理钱包在 Base 上按次以 USDC 付费。

可以做什么
提供十个工具用于创建和管理定时 webhook 任务。免费工具包括使用指南、钱包余额查询、计划校验并列出未来五次运行时间、任务状态、列出本机创建的任务，以及暂停、恢复或删除任务。付费工具用于创建任务或添加预付运行次数，并自动处理 x402 支付。计划可用自然语言或原始 cron 表达式书写，响应中带有 next_step 提示。
适用场景
适合让助手设置周期性对外 webhook 调用（例如定时通知或集成），并按次以 USDC 付费而非订阅。也适合需要小模型安全驱动调度的场景，因为付费调用前可免费校验计划。
运行要求
通过 npx 以 stdio 在本地运行，需要 Node.js。付费工具需要 CRON402_PRIVATE_KEY 中已充值的代理钱包私钥；没有它服务器以只读方式启动，免费工具仍可用。可选变量：CRON402_NETWORK（默认 eip155:8453，Base 主网）、CRON402_API_URL、CRON402_STATE_DIR（默认 ~/.cron402）。需要能访问 cron402 API 的网络。
安装前请注意
服务器要求提供 CRON402_PRIVATE_KEY 钱包私钥，该私钥控制资金，持有者可动用钱包中的 USDC。付费工具每次运行花费 0.008 USDC，充值金额为 0.008 至 0.80 USDC，会实际支出资金。管理工具会用该私钥在本地签名，delete_cron 会永久删除任务。创建的任务 id 保存在本地状态目录中。

安装

在 SourceWeft 中

  1. 打开 控制台中的 cron402，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。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

cron402-mcp

MCP server for cron402 — schedule webhook calls and pay per run in USDC on Base via x402. No accounts, no API keys; your wallet is the credential.

Built so that small models can drive it safely: schedules can be written in plain English, every schedule can be validated for free before a paid call, and every response carries an explicit next_step telling the model what to do next.

Price: $0.008 USDC per run · Network: Base mainnet (eip155:8453)

Quick start

bash
export CRON402_PRIVATE_KEY=0x...   # fund with USDC on Basenpx -y cron402-mcp

Optional env vars:

Tools

ToolCostDescription
cron402_guidefreeThe whole procedure, prices and rules — the tool a model should read first
check_walletfreeAddress, network, USDC/ETH balance, and how many runs it can afford
preview_schedulefreeValidate a schedule and list the next 5 run times in UTC
create_cron$0.008Create a scheduled webhook job (includes 1 run credit)
topup_cron$0.008–$0.80Add 1, 10, or 100 prepaid run credits
get_cronfreeJob status, credits, last 20 executions
list_cronsfreeJobs created from this machine, with live status
pause_cronfreePause a job (EIP-712 signed)
resume_cronfreeResume a paused job (requires credits)
delete_cronfreePermanently delete a job (EIP-712 signed)

Paid tools handle x402 payment automatically. Management tools sign locally with your key.

Designed for weak models

  • Plain-English schedules. "every 15 minutes", "every weekday at 9am", "every monday at 5pm", "weekly" and raw cron all work. Ambiguous or impossible phrases ("every 2 weeks", "at teatime") fail loudly with a fix, rather than silently scheduling the wrong thing.
  • Timezones. Pass timezone: "America/New_York" and the time-of-day is converted to the UTC cron the API stores, with a DST caveat in the response.
  • Free dry run. preview_schedule shows the next 5 fire times before a cent is spent, and create_cron re-validates locally so a bad schedule never costs money.
  • Money guardrails. Paid tools say PAID in their descriptions, name the exact amount, and every response tells the model not to call them twice.
  • Actionable errors. Insufficient funds, unreachable API, an unowned job or a localhost target each come back as { ok: false, error, next_step }.
  • Job memory. Created job ids are written to ~/.cron402/jobs.json so list_crons can recover them — the API has no list endpoint.
  • Starts without a key. A missing CRON402_PRIVATE_KEY degrades to read-only instead of failing to boot, so the model can explain what is missing.
