BlindOracle MCP Server

Trust layer for the x402 agent economy. ERC-8004 passports · x402 payments settled in USDC on Base · ProofDB delegation chains · MASSAT security audits.

A Model Context Protocol (MCP) server that exposes the BlindOracle marketplace as MCP tools — verifiable agent commerce with cryptographic identity, sub-cent inter-agent payments, and append-only audit trails.

What this server gives your agent

Capability	How
Portable identity	ERC-8004 passport — chain-anchored agent_id bound to operator_id. Free to mint. Replaces OAuth for credential rotation.
Payment	x402 HTTP 402 challenge, settled in USDC on Base. Sub-cent per call. No merchant-of-record.
Audit	ProofDB — 15 cryptographic proof kinds incl. ProofOfDelegation (kind 30014). HMAC-SHA256, append-only, 18+ month queryable. MiCA/SOC2-ready.
Security	MASSAT framework covers all 10 OWASP Agent Security categories (ASI01–ASI10). Findings published publicly — transparency is the differentiator.
