Overview
What is MoltPe?
MoltPe is an MCP server implementing payment tools for AI agents, supporting stablecoin micropayments (x402), session-based streaming (MPP), and traditional fiat payment paths. It is a reference implementation for developers building agent payment systems with mock data by default and optional live mode connecting to moltpe.com/mcp for real on-chain transactions.
How to use MoltPe?
Install the MCP server with cd mcp-server && npm install && npm start to run on port 3000 with 11 payment tools. Configure with Claude Desktop using the example config in examples/claude-desktop-config.json. For live mode, run PROVIDER_MODE=live MOLTPE_AGENT_TOKEN=swai_... npm start to connect to MoltPe’s production server.

FAQ from MoltPe
What is MoltPe compared to self-built payment stacks?
MoltPe is a reference implementation with mock data; for production, developers must implement real PaymentProvider adapters. It shows how agents can pay, get paid, and manage money across different protocols.
What runtime dependencies does MoltPe require?
Both the mcp-server and x402-client packages have zero runtime dependencies and zero npm audit vulnerabilities.
Where does payment data live?
By default, the server runs with mock data in all three payment providers. In live mode, it connects to moltpe.com/mcp for real on-chain transactions on Polygon and Base.
What are the known limits of MoltPe?
The project is a reference implementation not intended for production use without custom PaymentProvider adapters. It provides 11 MCP tools and supports three parallel payment paths with a 64-item production deployment checklist available.
What transport and auth does MoltPe use?
The MCP server runs on port 3000 and
