Monitor vs Datasieve
A side-by-side look at the Monitor and Datasieve MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Monitor for monitoring work as a local process; choose Datasieve for monitoring as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Monitor when
- You need dedicated capabilities in the Monitoring domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
Choose Datasieve when
- You need dedicated capabilities in the Monitoring domain.
- You prefer a local stdio subprocess transport.
- You want tools like
create_watch, watch_status, drain_events.

create_watchBuy a standing watch from DataSieve (https://api.datasieve.xyz). standard = $0.10/7d, 1 condition, 50 triggers; composite = $0.25/7d, up to 5 any-match conditions (e.g. 5 heartbeat dead-man switches), 200 triggers; standard30 = $0.35/30d and composite30 = $0.85/30d — one payment covers the month, for agents that will not be awake to renew weekly. Payment is a gasless USDC transfer signed locally. Events go to your webhookUrl (HMAC-signed) if set, and always to a server-side mailbox drained with drain_events; every event carries a signed Ed25519 observation receipt you can replay to third parties. Failed calls are never billed. The watch id + secret are remembered locally so later calls need only the id.watch_statusState, heartbeat lastCheckedAt, triggersUsed/cap, expiry, delivery stats, and for dead-man switches: up/down, lastPingAt, nextDeadline, pingUrl. Secret is looked up from local state if omitted.drain_eventsCollect everything the watch caught — works with zero infrastructure (the mailbox pattern). Pass `since` = last seen event id for incremental drains.renew_watchExtends the watch one more period (7 days, or 30 on the *30 tiers) at its tier price and resets the trigger budget. Renewing a paused watch also reactivates it.delete_watchpause_watchStop a watch firing (chain, web, heartbeat, schedule) without deleting it. The expiry clock keeps running. Use before a planned agent shutdown so your dead-man switch does not cry wolf.resume_watchBacklog-free resume: heartbeat deadlines restart from now and schedules jump to their next FUTURE slot — nothing that elapsed during the pause replays.cron_nextNext N run times for a cron expression in any IANA timezone, plus seconds-until-next. If the goal is for something to HAPPEN at those times, create_watch with a schedule condition instead — DataSieve fires the cron as signed webhooks for the life of the watch.x402_pingThe cheapest possible real x402 purchase: proves this wallet + client can pay a production seller before you point it at anything expensive. Returns payer + network; failed calls are never billed.verify_receiptEvery DataSieve event carries receipt {alg, keyId, statement, sig} — an Ed25519 attestation that DataSieve observed the event. This checks it against the service key, so an agent can validate evidence handed to it by ANOTHER agent without trusting that agent.ping_heartbeatKeep a dead-man switch alive. Pass the pingUrl from create_watch (or a watchId whose ping URLs are in local state). Call this at least once per intervalSeconds.service_healthScanner cursor lag vs chain head — verify the watcher is alive before you buy.- +7 more on the listing page

Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

Frequently asked questions
Monitor is categorized under Monitoring and uses a local stdio subprocess. Datasieve belongs to Monitoring and uses a local stdio subprocess. Pick Monitor for monitoring work and Datasieve for monitoring.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Monitor is listed as freemium — a free tier with paid plans. Auth: api key required. Datasieve has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add betterdb-inc-monitor and datasieve as separate keys in the same mcpServers object, and your assistant will call tools from either one.
