It currently has 0 GitHub stars and 0 forks, and sits alongside related tools like mcp-protocol-tester, awesome-mpp, inflow-node, APIbase, MPP-Inspector, SDAP.
Universal test suite for MCP servers — dual-rail payment testing (x402 + MPP/Tempo), 402 challenge validation, security audit, load testing. Works with any MCP-compatible server.
The MPP registry — 100+ Machine Payments Protocol tools, SDKs, services, and payment methods across 15+ chains. The definitive directory for Stripe + Tempo agent payments.
Official TypeScript/Node.js SDKs for the InFlow payments platform - x402 and MPP (Machine Payments Protocol) integration for sellers and buyers.
Universal MCP gateway for AI agents — 1108 tools, 307 providers. One endpoint (https://apibase.pro/mcp), pay-per-call with x402 USDC on Base + MPP USDC on Tempo.
A CLI tool and web dashboard for inspecting, testing, and debugging Machine Payments Protocol flows. Think "Postman for HTTP 402" — it visualizes the full challenge-response-receipt cycle, simulates payment failures, validates receipt signatures, benchmarks session channels, and generates test reports.
Secure Digital Agent Protocol — HTTPS for AI agent communication. Cryptographic identity, mutual authentication, encrypted payloads, trust delegation, and audit trails for multi-provider agent ecosystems. Works with A2A, MCP, and any agent-to-agent protocol.
