## Exfil surface

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

| 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. | `mcp__boundra__evaluate_payment` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `revoke_policy`

- The name "revoke_policy" says "revoke": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
[USER ONLY] Revoke a policy chain (takes effect immediately; subsequent payments default to DENY). Must carry the user's wallet signature over the revocation statement.
```

## Can't be undone (1)

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

### `evaluate_payment`

- The name "evaluate_payment" says "evaluate": a word for a change.
- The name "evaluate_payment" also says "payment": a word that usually means money moves, which cannot be taken back.
- The input addresses people (input.recipient): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.recipient): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Evaluate a payment intent. MUST be called before executing any payment. ALLOW = you may pay; DENY = you must abandon; ASK = a challenge is returned — relay the reason to the user, then retry with approval_token once the user signs. An optional mandate parameter carries a user-issued single-task authorization.
```

## Changes things (3)

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

### `render_template`

- 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
Render a natural-language rule from a template + parameters (then compile, sign & publish)
```

### `request_policy_change`

- The name "request_policy_change" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
[For agents] Ask the user for a policy/budget change (e.g. 'raise daily budget from 50 to 80'). The request is queued for user approval; the user signs and publishes a new policy version. Agents can NEVER change policy directly.
```

### `set_policy`

- The name "set_policy" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
[USER ONLY] Submit a new policy version. Must carry the user's wallet EIP-191 signature over the policy document; accepted only after signature + version-chain checks pass. Agents MUST NOT call this tool.
