Blindoracle MCP Server

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.

Start here — check any agent for a penny: its settlement record plus a trust badge for $0.02, no signup, no API key → Deep Ledger

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

Counterparty risk — what protects you when you buy or sell A2A

An agent-to-agent trade has two strangers and one broker. Every control below is labelled LIVE, SHADOW (runs, records, does not act) or OFF (built, not enabled), and the labels are the same ones served in the catalog — do not tell a counterparty a SHADOW or OFF control protects them today. Full page: counterparty-risk.html · kit doc: COUNTERPARTY-RISK.md (pack date 2026-09-19).

What this does not do: make the terms enforceable against a particular counterparty, give the buyer an active lever over released-vs-voided on the x402 pay-first path, or close the broker-trust gap — BlindOracle can see every reserve, deliverable and verdict. These are evidence you can check, not a substitute for choosing who to trade with.
