How do I install the datasieve mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `DATASIEVE_PRIVATE_KEY`, `DATASIEVE_API_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Datasieve MCP Server?

On-chain watches, web-page monitors, dead-man switches, cron, and agent coordination, paid via x402.

The short version

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
