## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__markets__discover` `mcp__markets__discover_categories` `mcp__markets__get_perp_candles` `mcp__markets__get_prediction_event` `mcp__markets__get_syndicate` `mcp__markets__get_token` `mcp__markets__get_token_candles` `mcp__markets__get_trader` `mcp__markets__get_trader_activity` `mcp__markets__get_trader_portfolio` `mcp__markets__leaderboard` `mcp__markets__list_perp_markets` `mcp__markets__list_syndicates` `mcp__markets__list_traders` `mcp__markets__search_assets` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `leaderboard`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The points leaderboard's top rows: rank, handle, score and referrals. Points, not trading performance; use list_traders for PnL.
```

## Only reads (14)

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

### `discover`

- The description's first verb is "browse": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Browse or filter the Discover index across spot tokens, tokenised stocks, perps and prediction markets; each row carries its venues, chains, outcomes and 24h stats. Filter by kind, venue, chain, class, tag or feed; sort by volume_24h, change_24h, market_cap, trending, ends_soon and more; page with cursor. For movers use kind=perp: spot change_24h is noise from illiquid pools unless filtered by liquidity. Prediction rows carry every outcome, so keep limit small (<=5).
```

### `discover_categories`

- The description's first verb is "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List the Discover categories (prediction-market tags and their slugs) usable as discover's `tag` filter.
```

### `get_perp_candles`

- The name "get_perp_candles" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Hyperliquid perp candles for one coin as parallel arrays t/o/h/l/c/v. `coin` is the bare Hyperliquid coin (BTC, not BTC-PERP; HIP-3 coins are dex-prefixed, e.g. xyz:NVDA). `interval` sets the bar size (default 1h). `from`/`to` are unix MILLISECONDS (default the last 7 days); returned `t` is unix seconds.
```

### `get_prediction_event`

- The name "get_prediction_event" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One Polymarket event (all its outcomes) by event slug, event id, market slug or condition_id: each outcome's price, bid/ask and price history, plus live game state for sports. Prices are YES probabilities 0..1. `interval` is the history's lookback window (1h, 6h, 1d, 1w, 1m, max), not a bar size; keep it short (default 1d) on many-outcome events.
```

### `get_syndicate`

- The name "get_syndicate" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One syndicate by id: its public page (name, pitch, operators, terms, members) under `syndicate` and its book (holdings, closed positions, balance curve) under `book`.
```

### `get_token`

- The name "get_token" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One token by chain and contract address: identity, mark price, liquidity and listings under `token`; per-window price change and 24h trading activity (volume, buys, sells, traders) under `stats`.
```

### `get_token_candles`

- The name "get_token_candles" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
OHLCV candles for one token by chain slug and contract address. `tf` sets the resolution; `from`/`to` are unix SECONDS. Always pass tf and from: with no window the answer runs to over a thousand bars. Use a coarse tf (60, 1D) for long windows.
```

### `get_trader`

- The name "get_trader" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
A trader's public profile by handle: user id, bio, avatar, follower and following counts, join date. Private and followers-only profiles answer not found.
```

### `get_trader_activity`

- The name "get_trader_activity" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

```

### `get_trader_portfolio`

- The name "get_trader_portfolio" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
A public trader's book by handle: open holdings and perps with value and PnL, closed positions, cash, realized PnL and the balance curve. Dust is hidden unless include_dust is true.
```

### `list_perp_markets`

- The name "list_perp_markets" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Raw Hyperliquid metaAndAssetCtxs (large): a universe array and a per-asset context array, parallel and joined by index, delisted coins included. Funding is the hourly rate as a fraction; open interest is in coin units. Use only for raw funding; screen perps with discover kind=perp.
```

### `list_syndicates`

- The name "list_syndicates" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The trading ranking: public traders by realized PnL, return or hit rate over a rolling window, with open value and balance per row. Few traders qualify; raise min_sales (default 5) to drop lucky one-sale records, and always show each row's `sales` beside its rank.
```

### `search_assets`

- The name "search_assets" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Search everything by text: tokens, perps, prediction markets and traders matching a ticker, name, address or handle. Start here to turn a name into the chain+address, coin or condition_id the other tools take. `limit` caps token hits only. Names are often ambiguous (many TRUMPs): pick by kind and liquidity.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.
