Zero

● degraded model-context-protocol-mcp

MCP connector (mcp.zero.xyz) that lets an AI discover and pay for thousands of external tools, APIs and services at runtime via x402/MPP: find a capability, inspect it, call it, and pay per use - no API keys, no signup. Free to use ($5 of credit to start; paid calls are usually pennies). Also ships a CLI and a Claude Code plugin. ([MCP](https://mcp.zero.xyz)) ([CLI](https://www.npmjs.com/package/@zeroxyz/cli))
