Overview

What is Openocean?

Openocean is an MCP server that integrates with OpenOcean’s aggregation API to enable token swaps across multiple decentralized exchanges. It is designed for MCP-compatible clients such as AI assistants, IDE extensions, or custom applications.

How to use Openocean?

Install the server via pnpm dlx openocean-mcp, a global install (pnpm add -g openocean-mcp), or by building from source. Configure your MCP client to run the server using the command pnpm with args ["dlx", "openocean-mcp"] (or "openocean-mcp" for global install) and provide any required environment variables. Invoke the exposed tools—such as QUOTE and SWAP—from the client to perform on-chain operations.

How is slippage configured in swap requests?

Slippage is passed as a percentage parameter (range 0.05 to 50) to the `QUOTE` and `SWAP` tools, with 1 representing 1% slippage.

What data does the server access?

It fetches on-chain data including quotes, gas prices, token lists, DEX lists, and transaction information via OpenOcean’s API.

How is the server invoked by an MCP client?

The client runs the server as a background process, typically set up with a command and arguments in the client’s MCP server configuration (e.g., using `pnpm dlx` or a global install).
