## 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__pkgs__npm_package` `mcp__pkgs__npm_search` `mcp__pkgs__npm_version` `mcp__pkgs__pypi_project` `mcp__pkgs__pypi_release` `mcp__pkgs__pypi_search` |
| 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 (4)

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

### `npm_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
Use when you need the public npm registry card for a package (scoped or unscoped): returns description, homepage, bugs URL, repository, license, keywords, maintainers as names only (emails stripped), number of versions, latest dist-tag version, created/modified times, and last-week download count from the official downloads API. Private packages are not supported. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.
```

### `npm_version`

- 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
Use when you need the exact published artifact for an npm version: dependencies, optionalDependencies, peerDependencies, bundledDependencies, engines, os/cpu, dist (tarball URL, integrity, shasum, unpacked size), and the version publish time. Give "latest" as version to resolve the current dist-tag. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.
```

### `pypi_project`

- 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
Use when you need the public PyPI project card: summary, home_page, project_urls, license, requires_python, a subset of classifiers, requires_dist (capped), current version, and yank status. Author/maintainer emails are omitted or redacted; only display names remain when present. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.
```

### `pypi_release`

- 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
Use when you need the published artifacts for a specific PyPI version: each file with filename, packagetype (sdist/bdist_wheel…), size, upload time, yank flags, digests (sha256/blake2b/md5) and download URL. Give "latest" as version to use the project's current version. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.
```

## Only reads (2)

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

### `npm_search`

- The name "npm_search" 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
Use to discover npm packages by keyword or name: returns up to 20 hits with name, version, description, keywords, date, and the registry search score. Publisher and maintainer emails are never returned (names/usernames only when present). Paid tool: x402 USDC on Base, $0.003 per successful call; call without payment to receive the PaymentRequired object.
```

### `pypi_search`

- The name "pypi_search" 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
Use when you have a likely PyPI project name (or a few tokens) and need to resolve it to live projects: tries the query as-is, PEP 503 normalization (lowercase, [-_.] → -), and hyphen/underscore/dot variants, then returns up to "limit" matching projects with summary, version, requires_python and license. This is name resolution, not full-text discovery — prefer exact package names when known. Author emails are redacted. Paid tool: x402 USDC on Base, $0.003 per successful call; call without payment to receive the PaymentRequired object.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__pkgs__npm_search",
      "mcp__pkgs__pypi_search"
    ],
    "ask": [
      "mcp__pkgs__npm_package",
      "mcp__pkgs__npm_version",
      "mcp__pkgs__pypi_project",
      "mcp__pkgs__pypi_release"
    ],
    "deny": []
  }
}
```

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

- `mcp__pkgs__npm_package`: untrusted-input
- `mcp__pkgs__npm_version`: untrusted-input
- `mcp__pkgs__npm_search`: untrusted-input
- `mcp__pkgs__pypi_project`: untrusted-input
- `mcp__pkgs__pypi_release`: untrusted-input
- `mcp__pkgs__pypi_search`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:18:52.449Z, unchanged since 2026-10-22T15:18:52.449Z. 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` |

- **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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://pkgs.scrapemole.workers.dev/mcp: tools/list returned 6 tools to an anonymous client, including npm_package (write), npm_version (write), pypi_project (write), pypi_release (write)
