## Findings

No check matched anything in these tool definitions.


## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `chain_yields`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Best yields on a specific chain. Shows top pools, total chain TVL, and average APY. Great for chain-specific farming strategies.
```

### `health_check`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Server health, data stats (pools/chains/protocols), API status, tool list, pricing.
```

### `risk_adjusted`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
🔒 PREMIUM (requires x402 payment, $0.08): APY adjusted for risk — pools ranked by real expected return after factoring liquidity, volatility, IL, and sustainability. The smart way to compare yields. → Call via https://tooloracle.io/x402/yield/mcp/ with X-PAYMENT header. New wallets get 5 free units auto-applied.
```

### `rwa_yield`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
🔒 PREMIUM (requires x402 payment, $0.05): Tokenized treasury and Real World Asset yields — BlackRock, Ondo, Maple, Centrifuge, Goldfinch and more. The institutional DeFi layer. → Call via https://tooloracle.io/x402/yield/mcp/ with X-PAYMENT header. New wallets get 5 free units auto-applied.
```

### `stablecoin_yield`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Safe stablecoin yields ranked by APY. Only pools with real TVL, filtered for sustainability (<200% APY). Perfect for treasury management.
```

### `yield_scan`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
🔒 PREMIUM (requires x402 payment, $0.03): Deep scan a specific pool or token — APY breakdown (base + reward), TVL, risk score, IL exposure, 30d average. Search by name, symbol, or pool ID. → Call via https://tooloracle.io/x402/yield/mcp/ with X-PAYMENT header. New wallets get 5 free units auto-applied.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `top_yields`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the highest APY yield pools across all chains and protocols. Filter by min TVL, chain, stablecoin-only. Data from 19K+ DeFi pools via DeFiLlama.
```

### `yield_compare`

- The name "yield_compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare two protocols side by side — average APY, max APY, TVL, chains supported, top pools. E.g. 'aave-v3' vs 'compound-v3'.
```
