## Findings

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

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

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

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

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

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

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

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

## Changes things (3)

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

### `is_market_open`

- The name "is_market_open" says "open": 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
Is a stock exchange open for trading right now (or at a given time)? Returns { open: true/false } plus status, when it next opens (weekends and holidays are skipped), and when it closes if currently open. The fastest answer to "is <exchange> open?".
```

### `markets_open_now`

- The name "markets_open_now" says "open": 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
Which of the world's stock exchanges are open right now (or at a given time)? Returns every tracked exchange with its open flag and status — ideal for "which markets are trading?".
```

### `time_until_next_open`

- The name "time_until_next_open" says "open": 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
When does an exchange next open? Returns hours until the next open (weekends and holidays skipped), or — if it is already open — hours until it closes.
```

## Only reads (5)

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

### `get_exchange`

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

Description, as the server wrote it:

```untrusted-server-text
The full record for one exchange: sessions (in exchange-local decimal hours), holidays, early closes, and official source links.
```

### `get_exchange_status`

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

Description, as the server wrote it:

```untrusted-server-text
Full live status for one exchange: open flag, status enum (main_open / session_open / opening_soon / closed), session type, hours to the next transition, hours to close (if open), and why it is closed (holiday / weekend) if applicable.
```

### `get_holidays`

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

Description, as the server wrote it:

```untrusted-server-text
The closure calendar for one exchange: full-day holidays (YYYY-MM-DD, exchange-local) and early-close days with their close times.
```

### `get_trading_sessions`

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

Description, as the server wrote it:

```untrusted-server-text
The trading-session structure for one exchange, in exchange-local decimal hours (9.5 = 09:30). A four-number "main" means a lunch break (e.g. Tokyo 9–11.5, 12.5–15).
```

### `list_exchanges`

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

Description, as the server wrote it:

```untrusted-server-text
List the tracked stock exchanges as lightweight summaries (id, name, city, country, timezone, region, importance). Optionally filter by region (e.g. "Asia", "Americas", "Europe"). Use this to discover valid exchange ids.
```
