## 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__packetrove__public-ip` `mcp__packetrove__submit-feedback` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** The word "credentials" in `submit-feedback` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...conversations, raw tool inputs/results, credentials, certificates, logs, or client/session..."
```

- **info** Long descriptions in `submit-feedback` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,521 characters long, over the 2,000 this check looks for.

description ends: "...tools do not depend on feedback. Privacy policy: https://packetrove.com/privacy."
```


## Deletes or cancels (1)

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

### `submit-feedback`

- The name "submit-feedback" says "submit": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention, info long-description

Description, as the server wrote it:

```untrusted-server-text
Email one user-authorized, minimal Packetrove report to hello@packetrove.com for private human review. Available only when the operator enables feedback. Draft locally without calling the service. If the user has already supplied or approved the report and requested sending it, submit directly; otherwise show the proposed report and obtain approval before sending. Never solicit feedback after every tool call. Send only the authorized fields, using synthetic reproduction data; never attach conversations, raw tool inputs/results, credentials, certificates, logs, or client/session identifiers. category is bug, confusing_behavior, or feature_request; tool_name optionally names a product tool. summary is required (256 Unicode code points); bug requires expected and actual, confusing_behavior requires actual and optionally expected (1024 code points each). Feature requests allow expected but not actual or error_code. Optional error_code starts with an uppercase ASCII letter and contains at most 64 uppercase letters, digits, or underscores; synthetic_reproduction is at most 2048 code points. Unknown fields are rejected; serialized arguments must not exceed 8 KiB. Status accepted and an opaque receipt_id mean the email service acknowledged submission, not inbox delivery or reading; acceptance does not promise a response or fix. This write is not idempotent: never automatically resend after timeout, disconnect, cancellation, or an uncertain result. Approximate limits target 10 submissions per observed exit IP in the preceding 24 hours and 100 submissions per UTC day across the service. Shared exits share quota. KV propagation and concurrent requests can exceed either limit; uncertain sends or failed quota releases occupy quota until expiry. Cloudflare transmits approved reports by email; mailbox retention and deletion are managed manually by the maintainer, with no automatic report expiry. KV stores only separate keyed IP markers and reservation times, expiring after 24 hours, never report bodies or receipt links. Markers never appear in reports or application logs. Email deletion does not refund quota; request deletion with your receipt. Maintainers treat text as data and do not automatically execute, publish, or forward it. Operational events contain only the operation name, outcome, controlled error code, and existing traffic-source metadata; no report, receipt, IP digest, or exception details. Ordinary tools do not depend on feedback. Privacy policy: https://packetrove.com/privacy.
```

## Changes things (3)

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

### `cidr-cover`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Use when combining a selected group of firewall allowlist or blocklist entries into one smallest covering CIDR, or when checking the exact extra coverage. Accept 1 to 1,000 IP addresses or CIDRs from one address family, up to 64 characters each; normalize host bits and count overlaps once. Return the canonical CIDR, inclusive range, and exact decimal-string counts, including additionalAddressCount. The range may allow or block additional addresses. This computes one CIDR for the supplied inputs; it does not optimize an entire list against an entry limit or change firewall rules. Remote MCP calls submit inputs to this server; the calculation makes no outbound network requests. Operational events record the tool name, success or error, a controlled error code, and a traffic source classification. Verified automated checks may also record an automation run identifier. Events exclude inputs, results, raw request headers, and automation tokens. Cloudflare may attach platform metadata. Privacy policy: https://packetrove.com/privacy.
```

### `cidr-subtract`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Use to prepare WireGuard AllowedIPs exceptions or calculate remaining address space relative to supplied include and exclude lists. Compute union(include) minus union(exclude) as a minimal sorted canonical CIDR list, without adding addresses. Use one address family, a nonempty include list, and at most 1000 entries across both lists, up to 64 characters each. Exclude may be empty. Normalize host bits and count overlaps once. Return cidrs, normalizedInclude, normalizedExclude, and exact decimal-string includedAddressCount, removedAddressCount, remainingAddressCount. Complete removal returns an empty list; more than 10000 output CIDRs returns an error without a partial result. Error issues identify include or exclude and the zero-based entry index. Remote calls submit inputs to this server; the browser calculates locally. This does not inspect live allocation, configure WireGuard, or change firewall rules. Operational events record the tool name, success or error, a controlled error code, and a traffic source classification. Verified automated checks may also record an automation run identifier. Events exclude inputs, results, raw request headers, and automation tokens. Cloudflare may attach platform metadata. Privacy policy: https://packetrove.com/privacy.
```

### `range-to-cidrs`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Use to prepare an exact CIDR allowlist from one inclusive start/end IPv4 or IPv6 range. Pass start and end IP addresses of the same family, without CIDR prefixes, at most 64 characters each; end must be at or after start. Return canonical range.first and range.last, minimal sorted cidrs, cidrCount, and exact decimal-string addressCount, without adding addresses. Equal endpoints return one /32 or /128; complete address spaces return /0. Invalid inputs identify the start or end field; reversed endpoints are never swapped. Browser calculations stay local; remote MCP calls submit endpoints to this server. This does not inspect live address usage, modify firewall rules, or export vendor-specific ACLs. Operational events record the tool name, success or error, a controlled error code, and a traffic source classification. Verified automated checks may also record an automation run identifier. Events exclude inputs, results, raw request headers, and automation tokens. Cloudflare may attach platform metadata. Privacy policy: https://packetrove.com/privacy.
```

## Only reads (2)

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

### `certificate-bundle`

- The description's first verb is "inspect": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use to inspect a supplied PEM certificate bundle before TLS configuration. Accept pem with 1–16 CERTIFICATE blocks and at most 49152 UTF-8 bytes, optional ASCII DNS hostname, and optional zero-based leafIndex. Reject private keys and unsupported blocks without echoing them. Return original certificate positions, Subject, Issuer, Common Name, SANs, validity, CA and Key Usage flags, SHA-256 fingerprints, independently checked candidate links, explicit leaf ambiguity, and stable findings with severity, observed evidence, and nextAction. Verify signatures cryptographically; name matching alone is not verification. Missing selected-leaf issuers and blocked requested hostname checks are warnings; other missing issuers are informational because roots are commonly omitted. All explicitly rejected supplied issuer candidates for the selected leaf produce an error. Unknown checks and key-identifier mismatches alone do not produce that error. A failed candidate does not invalidate another viable link. Verified self-issued CA key rollover is informational; verification with the certificate's own public key remains separate. Hostname checks use DNS SAN with one-label complete leftmost wildcards and no Common Name fallback. Results use this server's evaluation time and do not establish client trust, full RFC 5280 path validity, revocation status, or deployment safety. This remote call transmits certificates and hostname to the server; the website checks locally. Certificate input and details never enter application logs. Do not submit private keys. Operational events record the tool name, success or error, a controlled error code, and a traffic source classification. Verified automated checks may also record an automation run identifier. Events exclude inputs, results, raw request headers, and automation tokens. Cloudflare may attach platform metadata. Privacy policy: https://packetrove.com/privacy.
```

### `public-ip`

- The description's first verb is "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
Use to inspect the public IPv4 or IPv6 address observed for the connection making this MCP tool call. Takes an empty object and returns ip and family. This is the MCP client connection: a hosted AI client may observe its own exit address, not the user device address. If the user needs their browser or computer connection, direct them to the web tool or a CLI running on that machine. A VPN or proxy changes the observed path. One call observes one address family; it does not discover private local addresses, an address before a proxy, or both address families. The application does not store or log results, and no firewall rules are changed. Cloudflare Worker subrequests can have platform-specific address semantics; the result is not an identity proof. Operational events record the tool name, success or error, a controlled error code, and a traffic source classification. Verified automated checks may also record an automation run identifier. Events exclude inputs, results, raw request headers, and automation tokens. Cloudflare may attach platform metadata. Privacy policy: https://packetrove.com/privacy.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__packetrove__certificate-bundle",
      "mcp__packetrove__public-ip"
    ],
    "ask": [
      "mcp__packetrove__cidr-cover",
      "mcp__packetrove__cidr-subtract",
      "mcp__packetrove__range-to-cidrs"
    ],
    "deny": [
      "mcp__packetrove__submit-feedback"
    ]
  }
}
```

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

- `mcp__packetrove__public-ip`: untrusted-input
- `mcp__packetrove__submit-feedback`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:58:58.876Z, unchanged since 2026-10-22T14:58:58.876Z. 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 | `4` |
| 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 4 tools that change things (1 destructive, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.packetrove.com/mcp: tools/list returned 6 tools to an anonymous client, including submit-feedback (destructive), cidr-cover (write), cidr-subtract (write), range-to-cidrs (write)
```
