Openocean MCP Server

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.
