About FlashBank
FlashBank is an MCP server published by the GitHub account Rotwang9000. Fixed-fee P2P term loans (no oracles) and flash loans on Ethereum, Base, Arbitrum and Sepolia.
It runs on your own machine: your AI client starts it from the npm package @flashbank/mcp at version 1.1.1.
It asks for one secret: FLASHBANK_MCP_PRIVATE_KEY. Give it a key with the least access that still works.
Version 1.1.1 was published on 12 June 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
