BlindOracle MCP Server

Trust layer for the x402 agent economy. ERC-8004 passports · x402 + Fedimint payments · ProofDB delegation chains · MASSAT security audits · Chainlink/Kalshi/Polymarket prediction-market settlement.

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, append-only audit trails, and prediction-market settlement composed from Chainlink + Kalshi + Polymarket oracles.

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 + Fedimint ecash settlement. 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). Our own audit score (4.3/10) is published publicly.
Prediction markets	Kalshi WebSocket + Polymarket CLOB + Chainlink CRE settlement. Live treasury on Base.

Configuration

The server reads its operator-specific configuration from environment variables. No hard-coded secrets. Common variables:

Variable	Purpose	Default
BLINDORACLE_OPERATOR_EMAIL	Where alerts route to	[email protected] (placeholder)
BLINDORACLE_OPERATOR_WHATSAPP	P0 alert SMS-style channel	(none)
BLINDORACLE_SENDER_EMAIL	Outbound email From: address	[email protected] (placeholder)
BLINDORACLE_PASSPORT_ID	Your ERC-8004 passport ID	(mint free at the BlindOracle marketplace)
BLINDORACLE_ECASH_WALLET	Fedimint mint URL for ecash settlement	TheBaby federation default

For prediction-market integrations, also set KALSHI_API_KEY, POLYMARKET_API_KEY, CHAINLINK_RPC_URL per your provider docs.
