What's in the feed

x402 trust (per service)

  • trustScore, verdict, risk level & scam flags
  • receiver on-chain profile + USDC balance
  • compounding payTo & price history (can't be backfilled)
  • receiver stability, uptime %, first-seen
  • ecosystem aggregates + 402index accuracy audit

MCP security (per server)

  • safe / caution / avoid verdict + score
  • runs an install script? (arbitrary code on npm i)
  • abandoned / no-repo / no-license signals
  • weekly downloads + day-over-day deltas
  • sample of currently-flagged servers

Live incidents

  • receiver hijacks, bait-and-switch, honeypots
  • unverified receivers, price gouging, went-dark
  • each with on-chain proof (Base)

Who it's for

  • x402 / MCP trust & monitoring tools
  • agent frameworks (verify-before-pay)
  • ecosystem dashboards & researchers
  • anyone who'd otherwise scrape dozens of endpoints

Why PulseFeed

Other trust products score one side of one ecosystem, and all started recently. PulseFeed uniquely audits both x402 endpoints and MCP servers, continuously, over time — so the feed carries a longitudinal track record no snapshot can reconstruct. For builders of x402/MCP trust, uptime & monitoring tools, agent frameworks, ecosystem dashboards and researchers — get the whole enriched cross-domain dataset in one call instead of scraping dozens of endpoints.
