## Exfil surface

4 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__trueproxies__check_connection`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__trueproxies__get_account` `mcp__trueproxies__list_trusted_ips` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__trueproxies__check_connection` `mcp__trueproxies__get_account` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__trueproxies__check_connection` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__trueproxies__get_account` | `mcp__trueproxies__check_connection` | `mcp__trueproxies__check_connection` |
| `mcp__trueproxies__get_account` | `mcp__trueproxies__get_account` | `mcp__trueproxies__check_connection` |

## Findings

- **warn** Annotations that disagree with the tool in `generate_endpoints` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "generate_endpoints" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "generate_endpoints" says "generate": a word for a change.
```


## Can't be undone (1)

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

### `check_connection`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Sends one request through the service from TrueProxies and reports the outcome and exit IP, to tell a proxy problem apart from a website refusing you. It counts as use of the service: it uses a little traffic and starts an unused free trial. Does not measure speed. Limited to a few checks a minute.
```

## Changes things (1)

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

### `generate_endpoints`

- The name "generate_endpoints" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Builds proxy connection lines for a service with the chosen protocol, format, location targeting and session type: one line, or up to 1,000 sticky sessions with session sticky. Does not change the service. The output contains the proxy username and password, which let anyone who has them use the service.
```

## Only reads (10)

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

### `get_account`

- The name "get_account" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "return" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Returns the TrueProxies account that owns the API key: account reference, email, role, status and billing details.
```

### `get_invoice`

- The name "get_invoice" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns one invoice: status, amounts in cents, payment attempts and its service. Does not start a payment.
```

### `get_live_traffic`

- The name "get_live_traffic" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns live traffic for one service: download and upload speed in bits per second over the last ten seconds, traffic used today (UTC) and recent connection outcomes. last_activity_at shows how fresh the data is.
```

### `get_service`

- The name "get_service" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns one service: status, expiry, connection hosts and ports, capabilities (the targeting and session options it supports) and effective limits. Does not return the proxy password.
```

### `get_traffic_used`

- The name "get_traffic_used" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns traffic for one service, in bytes: bytes_out is downloaded and bytes_in is uploaded since the service started, remaining_bytes is traffic remaining and allowance_bytes is the allowance. traffic_batches lists traffic packs with their expiry. Traffic can take about a minute to appear.
```

### `get_usage_history`

- The name "get_usage_history" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns usage history for one service, or for the whole account when service_id is empty: connection success, traffic and connection errors over the last 24h, 7d or 30d. In series, bytes_out is downloaded and bytes_in is uploaded. Can lag recent traffic.
```

### `list_invoices`

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

Description, as the server wrote it:

```untrusted-server-text
Lists invoices with status (open, paid or cancelled), kind, amount in cents and the service each belongs to. Paginated: pass next_cursor from the previous response as cursor.
```

### `list_plans`

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

Description, as the server wrote it:

```untrusted-server-text
Lists TrueProxies plans and traffic packs: price in US cents, term, speed, connection limits, traffic allowance and targeting capabilities. Also returns the cities available for city targeting and whether the free trial is open. Traffic packs (residential_ipv4_gb) have no term; their traffic is valid for 30 days. No API key needed.
```

### `list_services`

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

Description, as the server wrote it:

```untrusted-server-text
Lists the services on the account with status, product, plan, expiry and connection hosts. Paginated: pass next_cursor from the previous response as cursor.
```

### `list_trusted_ips`

- The name "list_trusted_ips" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "password": it reads secrets.

Description, as the server wrote it:

```untrusted-server-text
Lists the trusted IPs of a service: addresses allowed to connect without the proxy password.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__trueproxies__get_account",
      "mcp__trueproxies__get_invoice",
      "mcp__trueproxies__get_live_traffic",
      "mcp__trueproxies__get_service",
      "mcp__trueproxies__get_traffic_used",
      "mcp__trueproxies__get_usage_history",
      "mcp__trueproxies__list_invoices",
      "mcp__trueproxies__list_plans",
      "mcp__trueproxies__list_services",
      "mcp__trueproxies__list_trusted_ips"
    ],
    "ask": [
      "mcp__trueproxies__check_connection",
      "mcp__trueproxies__generate_endpoints"
    ],
    "deny": []
  }
}
```

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

- `mcp__trueproxies__check_connection`: untrusted-input, outbound
- `mcp__trueproxies__get_account`: private-data, untrusted-input
- `mcp__trueproxies__list_trusted_ips`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:43:06.479Z, unchanged since 2026-10-22T14:43:06.479Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (1 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.trueproxies.com/mcp: tools/list returned 12 tools to an anonymous client, including check_connection (irreversible), generate_endpoints (write)
```
