## 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 (2)

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

### `render_document`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Produce a real .docx or .xlsx file from structured content and return it as base64. Send format ("docx"|"xlsx") plus exactly ONE of: blocks (array of {type:"title"|"heading"|"text"|"mono"|"table", text, level?, headers?, rows?}), markdown (string), sheets (array of {name, rows:[{...}] or rows:[[...]] with columns:[...]}), or templateId + values. Optional filename. Free for the first 5 documents a month on an API key sent as X-API-Key, then $0.25 per document via x402 -- an unpaid call over that returns a real HTTP 402 challenge. Dry run free at POST /sandbox/execute/render-document. Full schema and limits: call list_offerings with section "documents".
```

### `save_document_template`

- The name "save_document_template" says "save": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Free, and does not use your document allowance. Store a reusable layout once so you stop re-sending it: send format, blocks (or sheets), an optional templateId, with {{placeholders}} where values go, and a table may carry rowsFrom:"listName" to repeat one row over an array. Then render with { templateId, values }. Requires an API key (X-API-Key). Saves a large layout from being re-sent on every call, which is usually the single largest avoidable cost in a request.
```

## Only reads (1)

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

### `list_offerings`

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

Description, as the server wrote it:

```untrusted-server-text
Free. Everything 01Mind offers, on demand rather than loaded into your context upfront. section: "catalogue" (every purchasable listing with its price and the exact tool name to call it by -- most are callable but not advertised), "documents" (the full render_document schema, limits and templates), "venue" (open live-research studies you can take part in), or "all".
```

## Claude Code permissions
