## 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__depscout__check_dependencies` `mcp__depscout__check_lockfile` `mcp__depscout__check_package` `mcp__depscout__get_vulnerability` |
| 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.

### `check_dependencies`

- 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
Check up to 50 packages at exact versions (for example from package.json, package-lock.json, requirements.txt, go.mod, pom.xml, Cargo.toml or a .csproj) against OSV.dev in one batch. Returns a summary count and only the packages with problems: malicious-package flags first, then vulnerabilities by severity with the version that fixes each and the minimum upgrade target. Use when the user pastes a dependency file or list, or asks to "audit my dependencies" or "check my package.json / requirements.txt", or which dependencies are vulnerable or outdated. Entries without an exact version are skipped and listed; transitive dependencies are only checked if included in the list.
```

### `check_lockfile`

- 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
Audit a whole lockfile or dependency file in one call, including transitive dependencies where the file records them. Paste the file content as-is: package-lock.json, npm-shrinkwrap.json, yarn.lock, pnpm-lock.yaml, requirements.txt (== pins), poetry.lock, uv.lock, Pipfile.lock, Cargo.lock, go.sum, go.mod, packages.lock.json (NuGet) or gradle.lockfile. Up to 3,000 packages are checked against OSV.dev. Returns a summary and only the packages with problems: malicious-package flags first, then vulnerabilities by severity with the minimum upgrade target. Use when the user pastes or attaches a lockfile, asks for a full or transitive dependency audit, or asks "is my project vulnerable?". Prefer this over check_dependencies when the user has the file itself.
```

### `check_package`

- 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
Check one open-source package (npm, PyPI, Go, Maven, crates.io or NuGet) for safety and freshness. Returns a malicious-package flag (from OSV MAL- and malware advisories), known vulnerabilities with severity and the version that fixes each, the minimum version that clears all of them, the latest stable version, whether the given version is outdated or deprecated, licences, last release date, and the linked repository's OpenSSF Scorecard. If no version is given, the latest version is checked. Use when the user asks "is <package> safe?", "is it malware?", "which version should I use?", "should I upgrade?", or about a package's known CVEs, and before recommending any package or version to install (npm install, pip install, go get, cargo add, etc.). Data comes from OSV.dev and deps.dev; newly published malware may not be listed yet.
```

## Only reads (1)

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

### `get_vulnerability`

- The name "get_vulnerability" says "get": 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
Look up one vulnerability or malicious-package advisory by ID (CVE, GHSA, PYSEC, GO, RUSTSEC, MAL and other OSV IDs) and return its summary, severity, CVSS vector, aliases, publish date, the affected packages with their affected and fixed version ranges, and key references. Use when the user mentions a specific advisory or CVE ID ("what is CVE-2021-44228?", "am I affected by this GHSA?") and wants to know what it is, what is affected or which version fixes it. Only covers advisories in OSV.dev.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__depscout__get_vulnerability"
    ],
    "ask": [
      "mcp__depscout__check_package",
      "mcp__depscout__check_dependencies",
      "mcp__depscout__check_lockfile"
    ],
    "deny": []
  }
}
```

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

- `mcp__depscout__check_package`: untrusted-input
- `mcp__depscout__check_dependencies`: untrusted-input
- `mcp__depscout__check_lockfile`: untrusted-input
- `mcp__depscout__get_vulnerability`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:07:49.051Z, unchanged since 2026-10-22T15:07:49.051Z. 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 | `3` |
| 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` |

- **warn** 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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://depscout.salesup.workers.dev/mcp: tools/list returned 4 tools to an anonymous client, including check_package (write), check_dependencies (write), check_lockfile (write)
```
