## Exfil surface

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

| 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__decant__extract_web_page` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__decant__extract_web_page` `mcp__decant__submit_request` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `submit_request`

- The name "submit_request" says "submit": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The input carries an amount (input.budget.amount) and a currency, so it moves money.
- The input addresses people (input.geography.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.geography.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Send a requirement to one of Decant's services. It is kept with a reference number.
```

## Only reads (3)

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

### `describe_proposition`

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

Description, as the server wrote it:

```untrusted-server-text
Everything about one service: what happens to a request, what you get, scope and limits, the request fields and any operations.
```

### `extract_web_page`

- The description's first verb is "read": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "extract_web_page" says "web": it reads web pages, which anyone can write. The description's first sentence says "read" and "web": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Read one public web page into title, headings, text, links and JSON-LD. robots.txt is honoured.
```

### `list_propositions`

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

Description, as the server wrote it:

```untrusted-server-text
List Decant's services with a one-line summary: lookups that run instantly, and requirements you can send.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__decant__list_propositions",
      "mcp__decant__describe_proposition"
    ],
    "ask": [
      "mcp__decant__submit_request",
      "mcp__decant__extract_web_page"
    ],
    "deny": []
  }
}
```

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

- `mcp__decant__submit_request`: outbound
- `mcp__decant__extract_web_page`: untrusted-input, outbound
