Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Zero-knowledge proof generation MCP server for AI agents. Lets agents prove identity claims (Coinbase KYC, Country, Google OIDC, Google Workspace, Microsoft 365) without revealing personal information. Server-side proving in AWS Nitro Enclave TEE, paid via x402 USDC on Base. Built on Noir circuits (Aztec) and ERC-8004 agent identity. Reference application OpenStoa won 1st place at The Synthesis Hackathon ("Agents That Keep Secrets" track).
Proof-of-behavior enforcement for AI agents. Define behavioral covenant rules (permit/forbid/require), enforce at runtime before execution, get SHA-256 hash-chained tamper-evident audit logs, and verify compliance independently. Cross-agent verification handshake — no proof, no transaction. MIT licensed, 4,244 tests.
