Read-only Base mainnet verifier for x402 payment settlements. Connects your MCP client to Base's public RPC and exposes tools to verify USDC transfers on-chain, parse publisher manifests from `.well-known/x402`, decode payment headers, and audit receipts without touching a private key. Complements Coinbase's official Base MCP: that one signs transactions, this one independently confirms they happened. Ships with generic chain readers (balance, block number, tx receipts) plus x402-native tooling (verify_x402_settlement, probe_x402_endpoint, decode_x402_payment_payload). TensorFeed-flavored extras check AFTA federation status and lookup payments to TF's canonical wallet. Useful when an agent receives an x402 receipt and needs cryptographic proof the merchant didn't lie about the settlement.
