About Lumi Trades: x402 seller checks and test-buys

Lumi Trades: x402 seller checks and test-buys is an MCP server published by the GitHub account cypher-osiris. Free signed allow/warn/block before paying x402 sellers; test-buys on XRPL, Base and Stellar

It runs on your own machine: your AI client starts it from the npm package lumi-trades-mcp at version 0.9.9, or you can connect to the hosted version instead.

It asks for 2 secrets: EVM_PRIVATE_KEY and XRPL_SEED. Give it a key with the least access that still works.

Version 0.9.9 was published on 26 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 10 automated checks on the registry entry and the package code: 8 pass, 0 warn, 0 fail, 2 info. How we check.
