## 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__stratify__fetch` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__stratify__list_backtests` |
| 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 (4)

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

### `build_report`

- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Creates a shareable report page for a backtest the user owns and returns its URL. The page carries the honesty panel, equity and drawdown curves, walk-forward folds, the gross-to-net breakdown, a month grid and the trade table, computed from the stored backtest. Use when the user asks for a report or something to share.
```

### `my_feedback`

- 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
Reports this account has filed, and where each one stands. Use it to answer 'did that bug I reported ever get fixed?'.
```

### `run_backtest`

- The name "run_backtest" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Backtest an Indian index option strategy on real 1-minute NIFTY options data. Returns P&L after real charges and slippage, return-on-margin, and an honesty panel: out-of-sample split, walk-forward folds, bootstrap interval, and a deflated Sharpe that accounts for how many variants you have already tried. Refuses windows too narrow to be meaningful, and reports no ratios below 30 trades. Two spec forms: a PRESET (structure + params) for the common shapes, or an OPEN STRATEGY (legs + rules) for anything else — any number of legs at any strikes on any expiry, strikes chosen by percent, points, premium or delta, entry at any minute, and rules that CHANGE the position while it is live (roll a tested leg, close one side, add a hedge, trail a stop) plus book-level rules like standing down after three losers. Nothing here is restricted by tier; a paid tier only widens the date window.
```

### `submit_feedback`

- The name "submit_feedback" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Files a bug report or feature request when the user asks to report something. Confirm the title and body with the user before filing. Passing backtest_id attaches that backtest's spec so the issue can be reproduced.
```

## Only reads (7)

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

### `describe_coverage`

- The name "describe_coverage" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What data is available: symbols, date range, resolution, structures, gates, biases, the cost model, and every known gap.
```

### `explain_methodology`

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

Description, as the server wrote it:

```untrusted-server-text
How a result is produced: entry pricing, settlement, margin, slippage, the honesty rubric, and what each check can and cannot establish.
```

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag private-data: The description's first sentence says "fetch" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Fetch a document or backtest result by id, as returned by search.
```

### `get_backtest`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve a previous backtest result by its id — honesty panel, equity curve and per-trade detail, exactly as first computed.
```

### `list_backtests`

- The name "list_backtests" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The account's backtests, newest first, with id, date, trade count, net P&L and report URL. Answers a request for the most recent run, which list_strategies does not: that one returns only results that passed the evidence checks, ranked by consistency rather than by date.
```

### `list_strategies`

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

Description, as the server wrote it:

```untrusted-server-text
Strategies from THIS account's history that held up under out-of-sample and walk-forward checks, not merely ones that made money. Ranked by worst walk-forward fold — consistency, not size. Answers what has worked on this account so far without re-running anything.
```

### `search`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search what this service covers — symbols, dates, structures, signals, methodology. Returns ids usable with fetch.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `stratify`:

```json
{
  "permissions": {
    "allow": [
      "mcp__stratify__describe_coverage",
      "mcp__stratify__explain_methodology",
      "mcp__stratify__list_backtests",
      "mcp__stratify__get_backtest",
      "mcp__stratify__list_strategies",
      "mcp__stratify__search",
      "mcp__stratify__fetch"
    ],
    "ask": [
      "mcp__stratify__run_backtest",
      "mcp__stratify__submit_feedback",
      "mcp__stratify__build_report",
      "mcp__stratify__my_feedback"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__stratify__list_backtests`: untrusted-input
- `mcp__stratify__fetch`: private-data
