## 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__x207__x207_circle_overview` `mcp__x207__x207_epoch_report` `mcp__x207__x207_member_inspect` `mcp__x207__x207_order_status` `mcp__x207__x207_search_listings` `mcp__x207__x207_simulate_clearing` |
| 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 (3)

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

### `x207_circle_overview`

- 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
Overview of one x207 mutual-credit circle: its record and rules from the contract (get_circle, get_params) and its members (read API GET /members, or the contract view list_members when no read API is configured). Credit amounts are strings in the smallest unit (6 decimals).
```

### `x207_epoch_report`

- 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
The state and the result of one clearing epoch: the contract record (get_epoch) and, from the read API, the epoch summary (GET /epochs/{n}), its metrics (cleared ratio, GET /epochs/{n}/metrics) and its settlements (GET /epochs/{n}/settlements). Without epoch, the current epoch.
```

### `x207_simulate_clearing`

- 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
Asks the contract (view simulate_clearing) whether a proposed clearing for an epoch is valid and what it would clear. Each edge nets a debt: debtor owes creditor, `cleared` is the amount to cancel (decimal string, smallest unit). Changes nothing.
```

## Only reads (3)

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

### `x207_member_inspect`

- The name "x207_member_inspect" says "inspect": a word for reading.
- 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
One member of the circle: status, stake, position and credit limit. Uses the read API (GET /members/{account} and /members/{account}/limits), or the contract views member and limit when no read API is configured.
```

### `x207_order_status`

- The name "x207_order_status" says "status": a word for reading.
- 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
A service order of the circle's marketplace: parties, budget, milestones and status (read API GET /orders/{hash}). Without a hash, lists orders; filter by `party` and `status`.
```

### `x207_search_listings`

- The name "x207_search_listings" says "search": a word for reading.
- 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
Listings of the circle's marketplace (read API GET /listings): what an account offers and what it wants. Filters are optional; `status` defaults to open. Use `cursor` from `nextCursor` for the next page.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `x207`:

```json
{
  "permissions": {
    "allow": [
      "mcp__x207__x207_member_inspect",
      "mcp__x207__x207_search_listings",
      "mcp__x207__x207_order_status"
    ],
    "ask": [
      "mcp__x207__x207_circle_overview",
      "mcp__x207__x207_epoch_report",
      "mcp__x207__x207_simulate_clearing"
    ],
    "deny": []
  }
}
```
