Stellar Agent Search MCP

A read-only, keyless MCP server and CLI that lets AI agents or users discover, rank, and vet on-chain stellar-8004 agents on Stellar mainnet. It exposes the existing on-chain registry to MCP clients, keeps indexed reputation explicitly declared-vs-verified, and proves the full agent-finds-agent loop with recorded mainnet transactions. It supports preparing x402 (USDC pay-per-call) payments.
