Nano Empire – Open-source MCP gateway with x402 micropayments and A2A routing

说明与用途

Nano Empire 为 AI 代理提供微支付 MCP 网关，支持按调用付费，无需订阅，具备亚毫秒路由和计算委托功能。

问题

Monetization bottleneck for AI agent tools: existing MCP servers either consume developer API credits for free or require $20/month SaaS tiers that autonomous agents cannot subscribe to.

结果

Nano Empire enables autonomous agents to pay per tool call without subscriptions, achieving sub‑millisecond latency (p99 0.02 ms for 100 concurrent requests) and efficient compute delegation.

工作流

• 1. Agent discovers available tools via /mcp/manifest.
• 2. Agent sends request with x-402-receipt header to pay $0.01–$0.50 USDC per call.
• 3. Cerberus router selects optimal backend using UCB1 and Bloom filter guard.
• 4. If heavy compute required, agent POSTs to /a2a/delegate to subcontract to GPU cluster.
• 5. Payment settles on Solana USDC chain; agent receives receipt and tool response.
• 6. Agent processes response and continues workflow.

证据

Our agent just ran a full 8‑phase self‑demonstration—discovering the tools, hitting the paywall, settling on‑chain, and capturing an arbitrage task in 1,022ms (p99 latency 0.02ms for 100 concurrent requests).
