AgentSign – Zero trust for AI agents (OWASP-aligned)
Cryptographic agent passports when AI agent security is becoming a crowded category.

Agent accountability layer with identity + audit, but features are mostly API orchestration around five LLMs.
Teams deploying autonomous agents, agent platforms, enterprise AI governance
Anthropic's constitutional AI · OpenAI's GPT function calling · Chained LLM verification systems
MultiPowerAI is the trust layer the agent web needs:
- Cryptographic agent identity + trust scoring (<200ms) - Behavioral circuit breakers (auto-suspend on anomaly) - Human approval queues for high-stakes actions - Full cryptographic audit trail (every action signed + timestamped) - Skills marketplace (agents buy/sell capabilities, sellers keep 80%) - 5-model consensus: Claude + GPT + Gemini + DeepSeek in one API call
Free tier available. Would love feedback from anyone building production agent systems.
Cryptographic agent passports when AI agent security is becoming a crowded category.
Cryptographic proof enforces agent permissions, not just Langfuse-style observability.
The SDK exposes the exact primitives you want for autonomous-agent commerce: register/resolve identity, attest and badge verification, create/fund/cancel escrows, release/slash settlements, and reputation queries — plus event hooks. It's a smart, timely idea to stitch payments and trust into agent URIs, but the repo still reads like an early SDK: docs and integration examples are thin and there's no clear public security/settlement audit or adoption evidence yet.
Zero trust security for AI agents fills the MCP identity gap before competitors do.
Auth0 for AI agents, but the premise assumes a problem that doesn't yet exist.
Solves agent identity before standards bodies even finish the spec.
