## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `public_instrument_news`

- 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
Latest news for a ticker — headline, a short summary and a mandatory source_url to the original article (never the full third-party text). Use to ground a market read in recent, attributable news.
```

## Only reads (14)

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

### `get_crypto_context`

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

Description, as the server wrote it:

```untrusted-server-text
Crypto market context for a technical read: BTC/ETH dominance and total/alt market cap, Fear & Greed sentiment, perp funding rate & open interest (positioning/leverage), and the Stablecoin Supply Ratio (dry powder). Use ONLY when analysing crypto assets (BTC, ETH, crypto ETFs). Background context, not the primary signal.
```

### `get_event_stats`

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

Description, as the server wrote it:

```untrusted-server-text
Historical base rates for the technical events firing on a ticker today (e.g. RSI below 30, golden/death cross, new 52-week high/low). For each active event: the forward returns (1w/1m/3m/6m/1y) seen historically after similar events across the US universe, with the sample size and an unconditional baseline to compare against. Answers 'what usually happened after this'; small samples warrant caution.
```

### `get_instrument_info`

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

Description, as the server wrote it:

```untrusted-server-text
Current snapshot of one instrument: price and recent changes, session state (regular, pre-market, after-hours, closed), 52-week range, and market cap, sector and next earnings date where they apply. Covers the S&P 500, the Nasdaq-100 and popular US ETFs, major cryptocurrencies and the Cboe Volatility Index; crypto uses the -USD pair form (BTC-USD, ETH-USD), the VIX is ^VIX. Forex pairs, futures, options, other indices and non-US listings are not covered. Pass a ticker such as 'AAPL', 'SPY', 'BTC-USD' or '^VIX'.
```

### `get_intermarket`

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

Description, as the server wrote it:

```untrusted-server-text
Intermarket compass — a first-pass read of the market environment through price-ratio lenses: asset-class rotation (bonds vs stocks, commodities), risk appetite (high-yield vs investment-grade credit, small vs large caps, cyclicals vs defensives), defensive flows (gold, utilities, yield-curve proxy) and the dollar. Each lens reports rising/falling vs its 50-day average plus the 20-day change; overall posture is risk_on, risk_off or mixed. Optional focus= ('gold'|'bonds'|'tech'|'commodities'|'equity'|'crypto') adds lenses specific to that asset class.
```

### `get_key_levels`

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

Description, as the server wrote it:

```untrusted-server-text
Compute key price levels for a ticker: support/resistance zones (clustered swing highs/lows with touch counts = how often price reacted there), nearby round numbers, 50/200-day moving averages, and the 52-week high/low. Returns nearest levels above (resistance) and below (support) with distance %. Use these for concrete trigger/target/invalidation levels.
```

### `get_macro_context`

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

Description, as the server wrote it:

```untrusted-server-text
Get macro market context: sector P/E ratios, sector performance, US Treasury rates (2Y/10Y/30Y), CPI inflation data. Also provides key inter-market ratios (HYG/LQD, TLT/SPY) from our price data.
```

### `get_market_breadth`

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

Description, as the server wrote it:

```untrusted-server-text
S&P 500 market breadth: the percentage of index members above their 50-day and 200-day moving averages, with RSI, trend and 52-week range for each breadth series. A gauge of how broad the current advance or decline is.
```

### `get_monitoring_options`

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

Description, as the server wrote it:

```untrusted-server-text

```

### `get_price_history`

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

Description, as the server wrote it:

Description, as the server wrote it:

```untrusted-server-text
Relative strength of one ticker against another as a price ratio A/B (e.g. GDX/GLD, HYG/LQD, XLK/SPY, NVDA/SPY): how far the ratio sits above or below its 50- and 200-day averages, the ratio's RSI and trend, recent values, and a one-line verdict on which side is leading.
```

### `get_sentiment_data`

Flags a contrarian extreme when the equity put/call ratio or the VIX sits at one.
```

### `get_ta_methodology`

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