Fixed-fee P2P term loans (no oracles) and flash loans on Ethereum, Base, Arbitrum and Sepolia.
If you already use FlashBank, the flashbank mcp server is the piece that lets your assistant work with it directly. Fixed-fee P2P term loans (no oracles) and flash loans on Ethereum, Base, Arbitrum and Sepolia.
Non-custodial, on-chain lending where your funds stay in your wallet until the moment they're used. FlashBank is two complementary products that share that principle:
hardhat on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Dual — control admin.** Sensitive changes (token config, ownership, profit withdrawal) use a propose-then-execute flow split between the owner and aTime — only settlement.** Repay principal + a flat fee before maturity + grace, or the lender claims the collateral.

Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. FlashBank's toolset — Dual, Time, Architecture and 8 more — is a fair guide to whether it matches your workflow. It is maintained by Rotwang9000; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
