## Findings

- **warn** Annotations that disagree with the tool in `get_ledger_events` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_ledger_events" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "get_ledger_events" says "get": a word for reading.
```

- **warn** Annotations that disagree with the tool in `create_verified_pnl` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "create_verified_pnl" says "create": a word for a change.
```


## Changes things (4)

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

### `buy_report`

- 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
Buy the full report for one wallet and tax year ($29 up to 500 events, $59 up to 5,000, $99 above; upgrades charge the difference). method "card" charges the account owner's saved card: needs Authorization: Bearer ptx_… and the owner's opt-in; set max_price_cents to cap it. method "usdc" returns a quote: send exactly that USDC amount on HyperEVM (chain 999) to the given address, then call again with quote_id and tx_hash. (x402 clients can instead pay in USDC on Base or Solana at GET https://papertax.xyz/api/buy?address=…&year=….) Returns an unlock_token and export links. This spends money: confirm with the user first.
```

### `create_verified_pnl`

- The name "create_verified_pnl" says "create": 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
Read a wallet's results for one tax year from the chain and return a public, signed link (https://papertax.xyz/v/…) with a share image, for posting on X or anywhere else. Free, and nothing is stored. Dollar amounts are included only when amounts is true. With private true (the default) the wallet address is left out of the link and the page; with private false the page shows it, so check with the user first. It proves what the wallet did, not who owns it.
```

### `export_tax_file`

- 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
Koinly universal CSV, Crypto Tax Calculator advanced CSV, Cryptact custom file (JST, priced in yen by Cryptact), plain-text accountant summary, or the audit pack (audit = JSON with every figure tied to its transaction hash, a rules version and a data fingerprint; auditpdf = the printable PDF). Live wallets need paid access (API key or paid report). Large files are cut short with a download link.
```

### `get_ledger_events`

- The name "get_ledger_events" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Individual ledger rows with default tax classification: perp opens, closes, liquidations and funding; spot buys and sells; vault deposits and withdrawals; staking rewards; HyperEVM swaps and protocol deposits; transfers; papertrade mints and staking. Filter by event type or venue. Without paid access, live wallets return the first 10 rows.
```

## Only reads (7)

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

### `explain_tax_treatment`

- The name "explain_tax_treatment" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
papertax's default treatment notes for Australia, the US, the UK, Canada, New Zealand, Japan or Spain, optionally for one event type. Not tax advice.
```

### `get_games`

- The name "get_games" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How papertax games work (Edge, Climb, and 1v1 and Pit rooms on real papertrade positions, with crews and weekly leaderboards), this week's boards (top 10 players or crews; players show as their X account, papertrade name or wallet), open and live rooms, and the Bulls vs Bears tally. Read-only; playing needs the website and a wallet, and games open when trading on papertax goes live.
```

### `get_papertrade_positions`

- The name "get_papertrade_positions" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free, read-only. A wallet's papertrade (BTC and ETH perps on HyperEVM) balance and open positions: market, side, leverage, margin, entry, current price, liquidation price and how far away it is, and what each would keep if closed now, after papertrade's impact haircut and 2% win fee. Answers "how are my positions doing?". Closing or opening needs the wallet's signature on papertax.xyz.
```

### `get_papertrade_results`

- The name "get_papertrade_results" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free, read-only. What a wallet kept from papertrade closes over a period (default the last 30 days): closes, wins, losses, liquidations, win fees paid, PAPER minted, by market, and the best and worst trade. Answers "what did I keep this month?".
```

### `get_tax_summary`

- The name "get_tax_summary" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free. Per-venue realised gains and losses, fees, funding, liquidations, open positions and items needing review for one wallet and tax year, plus trading analytics (fee and funding drag, liquidation review, net after costs by market and month). For live wallets, report gives the event count, the full report's price for this caller, whether they already have access, and how to buy it.
```

### `get_top_traders`

- The name "get_top_traders" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free, read-only. papertrade's top traders by profit and loss over 24h, 7d, 30d or all time, or a search by leaderboard name or wallet, with the X account a trader signed in with, if any, and a link to their page on papertax.xyz/traders, where people can follow them. Not recommendations.
```

### `preview_papertrade_close`

- The name "preview_papertrade_close" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free, read-only. What closing one papertrade position (or all of them) would keep at the current price or a price you give, and what that does to the wallet's realised net for a tax year (all venues, and papertrade alone). Answers "what would closing my ETH long do to my tax year?". An estimate, not tax advice; nothing is closed.
```
