On-chain watches, web-page monitors, dead-man switches, cron, and agent coordination, paid via x402.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。

}
}在终端中运行这条命令
claude mcp add datasieve --env DATASIEVE_PRIVATE_KEY_FILE=your-value --env DATASIEVE_API_URL=your-value -- npx -y datasieve-mcp运行前请先填写空着的值。

MCP server for DataSieve — standing infrastructure for AI agents, paid over x402. On-chain conditions on Base (wallet activity, whale transfers, price crossings, new pools), url-change web monitoring (CSS selector / regex scoped), dead-man switches for your own agents (your agent pings a URL; silence fires the alert), cron schedules (fire a webhook every N seconds, at a time, or on a cron expression), and multi-agent coordination (barriers + locks). Every event carries a signed Ed25519 observation receipt. No account, no API key: one gasless USDC payment per watch, signed locally — your key never leaves your machine. Failed calls are never billed.
claude mcp add datasieve -- npx -y datasieve-mcp
Most tools work with no wallet at all — check our scanner's health, read watch status, drain events, ping dead-man switches, pause/resume, verify receipts, cancel watches. Only the buying tools spend money.
npx -y datasieve-mcp --install-skill
Installs a skill into ~/.claude/skills/datasieve/ that teaches Claude when to reach for standing infrastructure proactively: arm a dead-man switch before long autonomous work, schedule wake-ups, watch pages and wallets, coordinate sub-agents.
x402 means paying is a signature, so purchases need a key. Two rules:
echo '0xYOUR_BURNER_KEY' > ~/.datasieve/key.txt && chmod 600 ~/.datasieve/key.txt
claude mcp add datasieve -e DATASIEVE_PRIVATE_KEY_FILE=$HOME/.datasieve/key.txt -- npx -y datasieve-mcp
(DATASIEVE_PRIVATE_KEY=0x... inline also works if you prefer.)
The key never leaves the process: each payment is a signature authorizing exactly the route price — one at a time, nothing standing. Run payment_status to see the wallet, its balance, and prices before spending anything.
claude mcp add datasieve-sandbox -e DATASIEVE_API_URL=https://staging.datasieve.xyz \
-e DATASIEVE_PRIVATE_KEY_FILE=$HOME/.datasieve/key.txt -- npx -y datasieve-mcp
Same API, Base Sepolia, faucet USDC. Sandbox watches last 1 hour.
| tool | cost | what |
|---|---|---|
create_watch | $0.10 (standard/7d) · $0.25 (composite/7d, ≤5 conditions) · $0.35 (standard30/30d) · $0.85 (composite30/30d) | buy a watch; returns id, secret, ping URLs |
renew_watch | tier price | one more period, trigger budget reset |
coord_workspace | $0.25 / 7d | multi-agent barriers + locks; every op after is free |
cron_next | $0.001 | parse a cron expression: next N run times, any timezone |
x402_ping | $0.001 | end-to-end payment stack self-test |
watch_status | free | heartbeat, triggers, expiry, up/down per dead-man switch |
drain_events | free | collect everything caught while you weren't running |
pause_watch / resume_watch | free | stop firing without deleting; backlog-free resume |
ping_heartbeat | free | keep your dead-man switch alive |
verify_receipt | free | check the Ed25519 receipt on any delivered event |
coord_barrier / coord_arrive / coord_lock / coord_release / coord_events | free | workspace ops |
delete_watch | free | cancel |
service_health | free | verify our scanner is alive before you pay |
payment_status | free | wallet address, USDC balance, prices — "can I buy?" |
Watch ids and secrets are remembered in ~/.datasieve/watches.json (mode 600), so follow-up calls only need the watch id — the persistent memory your ephemeral agent lacks.
