### 2026-10-28 (score 66)

First indexed and scored.

## MCP tools (5)

### `list_base_yields` (~90 tokens)

List current staking/lending yield opportunities on Base (APY, TVL, project). Optional filters.

Input parameters:

- `asset` (string): Filter by asset symbol, e.g. ETH, USDC
- `minTvl` (number): Minimum TVL in USD
- `sortByApy` (boolean): Sort by APY descending
- `stable` (boolean): Only stablecoin pools

### `best_yield` (~45 tokens)

Get the single highest-APY pool on Base for a given asset symbol.

Input parameters:

- `asset` (string, required): Asset symbol, e.g. ETH, USDC, cbBTC

### `list_lending_vaults` (~62 tokens)

List curated lending markets on Base — Morpho ERC-4626 vaults and Aave V3 reserves: address, asset, APY, TVL. Rates for Aave are read from the Pool contract, not from a third-party snapshot.

### `yield_history` (~101 tokens)

Rate history for one market: daily APY/TVL plus min, median, max and volatility. Answers whether today's APY is typical for this market or a spike — a current rate on its own cannot tell you that.

Input parameters:

- `days` (number): Look-back window in days, default 30
- `pool` (string, required): Market id: a pool id from list_base_yields, or vault:<address> from list_lending_vaults

### `market_profile` (~105 tokens)

What to weigh besides the rate: size, how long the market has run, rate stability, how much of the APY is lending interest rather than incentives that can stop, the curator's cut, and how concentrated the deposits are. Returns every input alongside the score and the weights used, so the number can be recomputed rather than trusted.

Input parameters:

- `pool` (string, required): Vault symbol, address, or protocol-asset (e.g. sparkusdc, aave-usdc)
