About CrossFin
CrossFin is an MCP server published by the GitHub account bubilife1202. AI agent access to Asian crypto markets. Korean exchange routing and x402 paid APIs.
It runs on your own machine: your AI client starts it from the npm package crossfin-mcp at version 1.18.0, or you can connect to the hosted version instead.
It asks for one secret: EVM_PRIVATE_KEY. Give it a key with the least access that still works.
Version 1.18.0 was published on 25 February 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.
