Credit and payments for AI agent developers — over MCP. No crypto required

Provides a three-layer payment firewall for AI agents, enabling identity verification, risk screening, and execution authorization with on-chain policy enforcement for secure and auditable transactions.

MCP server for Sean-Claude Van Damme's General Store, enabling AI agents to browse and purchase digital goods and services using USDC payments over the x402 protocol.

MCP server that gives AI agents paid tools to de-risk costly actions: dependency vetting, x402 endpoint verification, JSON repair, and URL reading. Fronts the Guard HTTP API at guard.fabtally.com.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled.

Before an AI agent pays an x402 endpoint, checks whether it's safe to pay: liveness, scam/anomaly scan (payTo hijack, bait-and-switch, honeypot), and on-chain receiver verification. ~70% of x402 endpoints are dead or scams.
