## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| 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.

### `catalysts`

- 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
FREE. Dated, falsifiable events named on the board, optionally limited to those due within N days. Past-due events are excluded when a window is given. Upstream briefs land on about 71% of days; board content is same-day roughly half the time and is never more than three days old. Not real-time. Every payload carries stale / stale_days / built_from_brief_date — read them. Commentary on public statements, not advice. This tool does not accept portfolio, position or risk-profile inputs and will refuse them with HTTP 400.
```

### `coin`

- 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
FREE. One ticker's full current record — tier, channel, call, specifics, stance and previous stance, breadth, first/last seen — plus its catalysts and its anchor proof. The same facts are also free as static JSON at /coins/<TICKER>.json; this tool is the queryable form, not privileged content. Upstream briefs land on about 71% of days; board content is same-day roughly half the time and is never more than three days old. Not real-time. Every payload carries stale / stale_days / built_from_brief_date — read them. Commentary on public statements, not advice. This tool does not accept portfolio, position or risk-profile inputs and will refuse them with HTTP 400.
```

### `latest_board`

- 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
FREE. The whole current board: every coin row named in the latest videos of the tracked crypto YouTube channels, with the stance, the call and the dated specifics. Free. Upstream briefs land on about 71% of days; board content is same-day roughly half the time and is never more than three days old. Not real-time. Every payload carries stale / stale_days / built_from_brief_date — read them. Commentary on public statements, not advice. This tool does not accept portfolio, position or risk-profile inputs and will refuse them with HTTP 400.
```

### `stance_history`

- 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
FREE. The full stance arc for one ticker parsed into a dated series — one point per brief date with the movement (up / flat / down) — plus first and last brief, mention count and the flip flag. Derived from the published `arc` string; it is a parsed shape, not withheld data. Upstream briefs land on about 71% of days; board content is same-day roughly half the time and is never more than three days old. Not real-time. Every payload carries stale / stale_days / built_from_brief_date — read them. Commentary on public statements, not advice. This tool does not accept portfolio, position or risk-profile inputs and will refuse them with HTTP 400.
```

## Only reads (2)

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

### `board_snapshot`

- The name "board_snapshot" says "snapshot": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
FREE. The whole board as it stood on a past date, with that day's anchor proof. NOT YET AVAILABLE: only the current board is emitted, and no dated snapshot series has been anchored yet. The tool answers with available:false and is NOT charged while that is true. Commentary on public statements, not advice. This tool does not accept portfolio, position or risk-profile inputs and will refuse them with HTTP 400.
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
FREE. Substring search across the published columns (ticker, canonical name, call, specifics, tier, channel, stance) of the current board. Returns matches with the per-coin URL. Free. Commentary on public statements, not advice. This tool does not accept portfolio, position or risk-profile inputs and will refuse them with HTTP 400.
```
