This tutorial covers how to add Ophis as a goose extension so goose can turn natural-language swap requests into executable orders across supported chains.

Ophis is an intent-based DEX aggregator with a natural-language layer and a keyless MCP server for AI agents. It is non-custodial, gasless, and MEV-protected, and returns swap surplus to the trader. Ophis is a fork of CoW Protocol. It deploys its own settlement contract on Optimism and routes through CoW Protocol on the other supported chains: Ethereum, Base, Arbitrum, Polygon, BNB Chain, Gnosis, Avalanche, Linea, Plasma, and Ink.
The MCP server is keyless and requires no API key or environment variables. It exposes six tools: parse_intent, get_quote, build_order, submit_order, lookup_tier, and list_chains. Trades are signed by the user's own wallet, so the server never holds keys or funds.
Once Ophis is configured, you can describe a swap in plain language and ask goose to prepare an order. Here are some examples:
Parse an intent
Parse this swap intent: "swap 100 USDC for ETH on Base".
Get a quote
Get a quote to swap 0.5 WETH for USDC on Arbitrum.
List supported chains
Which chains does Ophis support?
The server returns a quote and an unsigned order. The actual trade is signed by your own wallet, so no keys or funds are ever shared with the extension.
