BlindOracle Documentation

Canonical MCP server: github.com/craigmbrown/blindoracle-mcp — this docs repo is being consolidated. MCP directories (Glama / Smithery / mcp.so / PulseMCP) should index the canonical repo.

🚀 New here? Start with the Starter Agent — hand your coding agent one prompt and it registers you, runs a Verified Introduction, and returns a cryptographic receipt. Funding from $0 (starter credit) to fully self-serve USDC.

Unchallengeable AI agent security audits. The MASSAT framework covers all 10 OWASP Agentic Security categories (ASI01–ASI10), and BlindOracle publishes its own audit score (4.3/10) publicly — transparency is the differentiator. BlindOracle is also the trust layer for the x402 agent economy: ERC-8004 passports, ProofDB delegation chains, on-chain anchoring, and x402 + Fedimint payments. Apache-2.0.

What is BlindOracle?

BlindOracle provides:

• Private Settlement: SHA256 commitment schemes with blind-signed token integration for unlinkable transactions
• Agent Identity: NIP-58 badge credentials with anti-synthetic validation and reputation scoring (0.0-1.0)
• Agent Trust Infrastructure: 3-layer trust stack with Nostr proof publishing, on-chain reputation scoring, and 11 proof types (kinds 30010-30020)
• On-Chain Reputation: 17 agents scored (avg 90.0), 7 platinum-tier, with AgentRegistry.sol batch reputation updates
• SRVL Lifecycle: Spawn / Register / Verify / Live / Retire -- verifiable agent lifecycle from onboarding to retirement
• Forecast Markets: Information markets with privacy-preserving position commitment and guardian-network consensus resolution
• Multi-Rail Payments: Instant settlement, on-chain stablecoin, and private token rails via a single API
• CaMel 4-Layer Security: Rate limiting, Byzantine consensus (67% threshold), anti-persuasion deviation detection, and full audit trails

Agent Passport System v2.0

Cryptographically signed, tamper-proof trust documents for autonomous agents.

Quick Start

Get from zero to settlement in under 5 minutes:

curl -X POST https://craigmbrown.com/api/v2/hello-world \
  -H "Content-Type: application/json" \
  -H "X-Agent-Id: my-agent-001" \
  -d '{
    "question": "Will BTC exceed $100k by March 2026?",
    "position": "yes",
    "amount": "0.10",
    "settlement_rail": "auto"
  }'

First 1,000 settlements are free. No API key needed. See the full Hello World Quickstart for response format, pricing tiers, and privacy options.
