BlindOracle Documentation
Canonical MCP server: github.com/craigmbrown/blindoracle-mcp โ this docs repo is being consolidated. MCP directories (Glama / Smithery / mcp.so / PulseMCP) should index the canonical repo.
๐ New here? Start with the Starter Agent โ 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 (ASI01โASI10), and BlindOracle publishes its own audit score (4.3/10) publicly โ 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.solbatch 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
