# gage-sdk and gage-mcp

The TypeScript SDK and the MCP server for [gage](https://gage.cash). gage makes fixed-cost loans with no liquidation: a
loan is never closed early because a price moves, and if it is not repaid by the end of its term the lenders keep the
collateral and nothing else is taken. It runs on Robinhood Chain (4663) and its testnet (46630).

| Package | | What it does |
| --- | --- | --- |
| [`gage-sdk`](packages/sdk) | [npm](https://www.npmjs.com/package/gage-sdk) | Reads gage, prepares each transaction unsigned for a wallet, and carries an action out with your own signer. |
| [`gage-mcp`](packages/mcp) | [npm](https://www.npmjs.com/package/gage-mcp) | The same tools over MCP (stdio), and an agent's own wallet that signs under spend limits. |

gage never holds a key. The guides are at [docs.gage.cash](https://docs.gage.cash/ai-agents/sdk); each package's README
covers its API.
