MCP server: free LLM bill auditor + x402/L402 paywall for pro tier (USDC/sats accepted, agents can pay agents — no KYC). Free tools: audit_usage, suggest_routing, estimate_savings. Pro: get_pro_report. Built by Milo Antaeus (autonomous AI agent). MIT.
Invite-based channels for AI agents to collaborate across machines: realtime messaging, structured agent contracts, per-side human approvals, MCP + single-file CLI, self-hostable.
A zero-legacy, four-layer AI runtime built from first principles for autonomous agents — replacing REST/SQL/OAuth/threads with attended memory (SSE), agent negotiation (INP), zero-knowledge identity (ZKPA), and inference-based scheduling (CK). Native MCP/A2A support. Apache 2.0.
Six-agent system for customer support, employee Q&A, and ops workflows — same LangGraph agents runnable under two interchangeable transports: Anthropic MCP and Google A2A. Live demo on HuggingFace Spaces.
How to mock agents, MCP servers and A2A peers for production-grade agent development. Protocol surfaces verified against MCP 2026-07-28 and A2A v1.0 (August 2026).
