## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__tilla__tilla_about` `mcp__tilla__tilla_changes` `mcp__tilla__tilla_docs` `mcp__tilla__tilla_health` `mcp__tilla__tilla_inventory` `mcp__tilla__tilla_latest` `mcp__tilla__tilla_market` `mcp__tilla__tilla_markets` `mcp__tilla__tilla_sample` `mcp__tilla__tilla_status` `mcp__tilla__tilla_tick` `mcp__tilla__tilla_tiers` `mcp__tilla__tilla_usage` `mcp__tilla__tilla_window` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

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

### `tilla_about`

- 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
What TILLA is, who it's for, and how to start. No API key needed.
```

Description, as the server wrote it:

```untrusted-server-text
Every value our checks repaired since `since` ('YYYY-MM-DD HH:MM:SS') that the key holds, with its value now -

Exactly what the caller's key holds. No arguments: every lane per layer with its series
count. layer=raw|derived|node and lane=1min|hour|daily|...: every series name there. Call
this before tilla_latest / tilla_window and use the names it returns. Needs TILLA_API_KEY.

markets (btc: its ETFs and miners). period = 1d 7d 30d 2m 3m 6m 1y 2y 3y all. At most 200 columns an answer:

tilla_inventory, or a pattern like 'btc_*' / '*_close'; or `markets` + `fields` ('btc,eth' + 'close,volume' ->
btc_close, btc_volume, eth_close, eth_volume). layer = raw | derived | node | deep; lane = 1min, 5min, hour,
