# Zyfai

> Zyfai is a self-custodial DeFi yield agent for discovering risk-adjusted opportunities and automating allocation, monitoring, and rebalancing across supported protocols.

Zyfai supports Ethereum Mainnet, Base, and Arbitrum. Users retain ownership of their funds through an EOA-controlled Safe subaccount. Zyfai session permissions support portfolio automation but do not give Zyfai or an AI client custody of the user's wallet.

## Use Zyfai with AI

- [Agent skill](https://zyf.ai/skill.md): Paste target for connecting an AI client. Fetch it, then follow the setup guide.
- [AI client setup guide](https://docs.zyf.ai/docs/sdk/mcp-server.md): Full harness steps, verification, and deposit signing. Fallback without `.md`: https://docs.zyf.ai/docs/sdk/mcp-server
- [Hosted MCP endpoint](https://mcp.zyf.ai/mcp): Remote Streamable HTTP endpoint.
- [Official MCP Registry entry](https://registry.modelcontextprotocol.io/v0/servers?search=io.github.ondefy/zyfai): Registry ID `io.github.ondefy/zyfai`.
- [MCP server source](https://github.com/ondefy/zyfai-mcp-server): Source, deployment information, and contributor setup.

Connecting the MCP server does not transfer assets, reveal private keys, bypass wallet approval, or give the assistant custody. Public opportunity discovery may be available anonymously; portfolio data and account actions require authentication. Transactions that require a wallet signature remain subject to explicit user approval.
