## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__crypto-quant-signal__chat_knowledge` `mcp__crypto-quant-signal__get_track_record` `mcp__crypto-quant-signal__search_knowledge` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__crypto-quant-signal__chat_knowledge` `mcp__crypto-quant-signal__get_market_regime` `mcp__crypto-quant-signal__get_track_record` `mcp__crypto-quant-signal__get_trade_call` `mcp__crypto-quant-signal__get_trade_signal` `mcp__crypto-quant-signal__scan_funding_arb` `mcp__crypto-quant-signal__scan_market_regimes` `mcp__crypto-quant-signal__scan_trade_calls` `mcp__crypto-quant-signal__search_knowledge` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

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


## Changes things (3)

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

### `scan_funding_arb`

- 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
Ranked cross-venue funding arbitrage across major crypto perpetual futures venues — funding rate spreads, long one venue short another, as a BUY SELL HOLD composite verdict per pair. AI trading signal for crypto quant and Claude trading agents. Trade call via get_trade_call, market regime via get_market_regime. On-chain verified merkle anchor.
```

### `scan_market_regimes`

- 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
Screens a whole crypto perpetual futures venue by market regime — TRENDING_UP TRENDING_DOWN RANGING VOLATILE — and returns each matching coin with confidence, trend strength, ADX, volatility ratio and how long the regime has held. Rows are the market regime classifier output for the last closed bar, sampled on Binance, Bybit, OKX and Bitget; another venue, or a timeframe a venue cannot serve, is refused with the alternatives. Billing: one call per returned row; non-matching coins are free. For a live single-coin read with cross-venue funding, call get_market_regime. Read-only.
```

### `scan_trade_calls`

- The name "scan_trade_calls" says "call": a word for a change.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns ranked BUY SELL HOLD trade calls across the top crypto perpetual futures by open interest — one scan for whole-market coverage, each with confidence and market regime. Use this for breadth; use get_trade_call for per-coin depth and reasoning. Read-only: reads live exchange APIs, places no orders.
```

## Only reads (6)

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

### `chat_knowledge`

- The description's first verb is "return": a word for reading.
- Tag private-data: The name "chat_knowledge" says "chat": it reads messages. The description's first sentence says "return" and "vault": it reads secrets.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "chat_knowledge" says "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Returns a synthesized natural-language answer with citations, grounded in the AlgoVault knowledge bundle (every MCP tool description, response shape, integration tutorial, and code example). Use when you need an explanation, code pattern, or how-to; for raw ranked snippets without LLM synthesis use search_knowledge (faster, no quota cost). Read-only: calls an LLM, no other side effects. Quota: Free 10/month, Starter 50, Pro 200, Enterprise 2000.
```

### `get_market_regime`

- The name "get_market_regime" 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
Returns the market regime — TRENDING_UP TRENDING_DOWN RANGING VOLATILE — with confidence and a strategy hint, for one crypto perpetual futures. Composite verdict: trend ranging + cross-venue funding rate. Read-only, live exchange APIs. Verified track record: get_track_record or performance://signal-performance; on-chain verified merkle anchor.
```

### `get_track_record`

- The name "get_track_record" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "vault": it reads secrets.
- 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
Returns the AlgoVault track record — aggregated PFE win rates by call type, timeframe and asset tier, plus the evaluation methodology and window. The same verified aggregate the performance://signal-performance resource serves, callable from harnesses that bridge tools only. Defaults to the compact aggregate; use include for the per-asset, per-venue or recent-signal breakdowns. Read-only, no side effects.
```

### `get_trade_call`

- The name "get_trade_call" 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
Returns a composite verdict — BUY SELL HOLD trade call with confidence and market regime — for one crypto or tokenized-stock perpetual futures. One asset only; whole-market scan: scan_trade_calls. Read-only: live exchange APIs, no orders. Verified track record: get_track_record or performance://signal-performance; on-chain verified merkle anchor.
```

### `get_trade_signal`

- The name "get_trade_signal" 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
Returns a composite verdict — BUY SELL HOLD trade call with confidence and market regime — for one crypto or tokenized-stock perpetual futures. One asset only; whole-market scan: scan_trade_calls. Read-only: live exchange APIs, no orders. Verified track record: get_track_record or performance://signal-performance; on-chain verified merkle anchor. [ALIAS] This tool is an alias of get_trade_call — same behavior, kept for backward compatibility. Prefer get_trade_call for new integrations.
```

### `search_knowledge`

- The name "search_knowledge" says "search": a word for reading.
- Tag private-data: The description's first sentence says "return" and "vault": it reads secrets.
- 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
Returns ranked snippets from the AlgoVault knowledge bundle answering a question about its MCP tools, response shapes, integration patterns (LangChain, LlamaIndex, MAF, CrewAI), or code examples. Call this BEFORE other tool calls to confirm parameter usage and avoid hallucinating tool shapes. Fast: BM25 lexical search, no LLM call, no quota cost. For a synthesized natural-language answer use chat_knowledge. Read-only, no side effects.
```
