Rhaios

Rhaios is the execution engine agents call for onchain yield. MCP (Model Context Protocol) is the canonical interface for that execution layer. Your agent connects over MCP and gets 4 tools for preparing and executing yield intents on Base. Rhaios is non-custodial — your agent keeps its own keys. We never hold funds or signing authority.

​
Canonical endpoint

https://api.rhaios.com/mcp
Production transport is HTTP MCP (streamable HTTP), server-to-server.
MCP is the transport layer. Rhaios value is deterministic yield strategy preparation, execution safety checks, and inspectable outputs.

​
What your agent can do

Prepare intents

Use yield_prepare for deposit, redeem, and rebalance. Get strategy outputs plus setup or execution calldata.

Execute on-chain

Submit signed transactions with yield_execute. Supports first-time EIP-7702 setup flows and standard execution flows.

Track positions

Use yield_status for current portfolio positions and performance.

Analyze history

Use yield_history for APY and TVL time series by vault and period.

​
How it works

1

Connect

Point your agent at the Rhaios MCP endpoint. Works with Claude Desktop, custom agents, or any MCP-compatible client.
2

Prepare an intent

Call yield_prepare with operation, asset/amount (for deposit), and your agent address. Rhaios returns strategy data and unsigned setup or execution payloads.
3

Sign the transaction

Your agent signs the payload with its own key. If setup is required, execute the setup type-4 transaction first, then prepare/sign the execution intent.
4

Execute on-chain

Pass the signed transaction to yield_execute. Rhaios submits it and returns the receipt.
