Overview

An open-source, non-custodial payment layer that implements the x402 standard for AI agents using the Model Context Protocol (MCP). It enables pay-per-use interactions without central custody of funds, serving as an alternative to Vercel's x402-mcp implementation. Built in TypeScript, it integrates payments directly into agent workflows.

Best for

Best for
Developers building AI agents that need a self-hosted, non-custodial payment layer for pay-per-use interactions.

Use cases

• Monetizing AI agent interactions with per-request microtransactions
• Enabling payments in MCP-compatible agent toolchains or APIs

Use cases

• Monetizing AI agent interactions with per-request microtransactions
• Enabling payments in MCP-compatible agent toolchains or APIs
• Adding a non-custodial payment gate to autonomous agent services

Pros

• Non-custodial design keeps users in control of their funds
• Open-source alternative to a proprietary solution (Vercel x402-mcp)
• Written in TypeScript for broad compatibility in modern agent stacks

Cons

• Very low community traction (4 stars) indicates early-stage maturity
• Limited ecosystem support and likely sparse documentation
• Requires integration with both x402 and MCP infrastructure
