```untrusted-server-text
The server marks "trade_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "trade_link" says "link": a word for a change.
```

## Changes things (5)

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

### `fair_value`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Last US market price and market status of listed stocks (what the tokens track). Up to 12 tickers.
```

### `strategy_link`

- The name "strategy_link" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
A pre-filled River strategy card link (Base, ST0x stocks). Cards and fields: dip (budget, start, step, rungs); peg (amount, discount, max); recurring (budget, days, hours, max); cycle (budget, buy, step, levels, repeat, top, sell); take-profit (amount, target); sell-ladder (amount, first, last, parts); stop (amount, trigger, floor); breakout (amount, trigger, max); spread (amount, spread, weekend); portfolio (amount, preset, stocks). Missing fields are left for the user. See https://theriver.markets/llms.txt for what each card does. The user reviews this on The River and signs in their own wallet; nothing happens until they do.
```

### `trade_link`

- The name "trade_link" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
A pre-filled River trade link. A buy by ticker with usd (no address or chain) returns a best-price link that opens the cheapest issuer for the user. Give exactly one of usd (buy only, settlement stablecoin, up to 6 decimals) or qty (tokens, up to 18 decimals). The user reviews this on The River and signs in their own wallet; nothing happens until they do.
```

### `wallet_holdings`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Any wallet's stock-token and cash balances on every chain The River serves (public onchain data), plus its read-only River profile link.
```

### `wallet_pnl`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Any wallet's profit and loss on Base, from public chain data. Wallet: its stock tokens since 1 Oct 2026, average cost from the wallet's own USDC trades on any venue (DEX or orderbook), realised and unrealised per token; transfers are never priced. Strategies: one row per strategy (live and cancelled orders it placed, incl. its RiverAccount): fills, USDC spent and received, tokens bought and sold, and P&L at today's prices (value now minus what was put in). Robinhood Chain is not counted yet (stated in notes).
```

## Only reads (2)

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

### `compare_issuers`

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

Description, as the server wrote it:

```untrusted-server-text
Where a tokenized stock is cheapest: each issuer's token (ST0x, Coinbase, Robinhood) priced per share for a $100 buy, against the stock's own price (US, or the home exchange's in dollars), with the gap in % and the lowest issuer. From quotes taken every 5 minutes (biggest stocks) or hourly; the time is in the answer. Not a live quote: for an executable best-price buy use trade_link with usd. Up to 12 tickers.
```

### `list_stocks`

- The name "list_stocks" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Tokenized stocks listed on The River, with ticker, token symbol, issuer, chain and trade link. Filter by chain and/or a search query (ticker, symbol or name).
```
