## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__software-lifecycle__eol_products_by_category` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__software-lifecycle__eol_latest_release` `mcp__software-lifecycle__eol_product_search` `mcp__software-lifecycle__eol_products_by_category` `mcp__software-lifecycle__eol_products_by_vendor_tag` `mcp__software-lifecycle__eol_tags` `mcp__software-lifecycle__eol_unsupported_releases` |
| 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 (2)

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

### `eol_latest_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
What is the latest version of a product right now? Returns the newest release cycle, its latest patch version and date, release date, support status and end-of-life date. Live data avoids out-of-date answers about "the latest Python/Node/PostgreSQL". Source: endoflife.date (community-maintained, typically refreshed daily); preview or beta releases are not included. (cost: 1 credit)
```

### `eol_unsupported_releases`

- 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
Which versions of a product are already end of life? Lists the release cycles past their end-of-life date, newest first, with the end-of-life date, the last patch version and whether extended (often paid) support is still available. Useful for security audits and spotting outdated versions in an estate. Source: endoflife.date (community-maintained); it reports published dates, not whether a given install is patched. (cost: 1 credit)
```

## Only reads (4)

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

### `eol_product_search`

- The name "eol_product_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
Find the endoflife.date product slug for an everyday name or alias ("postgres", "k8s", "node", "windows server") and check whether a product is tracked at all. Matches names, labels and aliases and returns the best matches first. Use it before the other end-of-life tools. Source: endoflife.date product list (about 490 products); untracked software returns no match. (cost: 1 credit)
```

### `eol_products_by_category`

- The description's first verb is "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "database": it reads databases.
- 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
List the products endoflife.date tracks in one category: operating systems, databases, programming languages, frameworks, server applications, cloud services, applications, devices or standards. Returns each product slug, name, aliases and tags so you can then look up release dates. Source: endoflife.date; coverage is about 490 products and is not a full software inventory. (cost: 1 credit)
```

### `eol_products_by_vendor_tag`

- The description's first verb is "list": 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
List the products endoflife.date tracks under one tag, usually a vendor (microsoft, amazon, google, oracle, red-hat), a family (linux-distribution) or a runtime (php-runtime, javascript-runtime). Answers "which Microsoft products have end-of-life dates" before you look up each one. Source: endoflife.date; tags are the project's own grouping (see eol_tags) and a vendor's list may be incomplete. (cost: 1 credit)
```

### `eol_tags`

- The description's first verb is "list": 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
List every tag endoflife.date uses to group products: vendors (microsoft, amazon, google), families (linux-distribution) and runtimes (php-runtime, java-runtime). Use it to find a valid tag for eol_products_by_vendor_tag. Source: endoflife.date; tags are the project's own grouping, not an official vendor list. (cost: 1 credit)
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `software-lifecycle`:

```json
{
  "permissions": {
    "allow": [
      "mcp__software-lifecycle__eol_products_by_category",
      "mcp__software-lifecycle__eol_products_by_vendor_tag",
      "mcp__software-lifecycle__eol_product_search",
      "mcp__software-lifecycle__eol_tags"
    ],
    "ask": [
      "mcp__software-lifecycle__eol_latest_release",
      "mcp__software-lifecycle__eol_unsupported_releases"
    ],
    "deny": []
  }
}
```

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

- `mcp__software-lifecycle__eol_latest_release`: untrusted-input
- `mcp__software-lifecycle__eol_unsupported_releases`: untrusted-input
- `mcp__software-lifecycle__eol_products_by_category`: private-data, untrusted-input
- `mcp__software-lifecycle__eol_products_by_vendor_tag`: untrusted-input
- `mcp__software-lifecycle__eol_product_search`: untrusted-input
- `mcp__software-lifecycle__eol_tags`: untrusted-input

## Remote posture

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://ukdata.reliness.co.uk/mcp/software-lifecycle: tools/list returned 6 tools to an anonymous client, including eol_latest_release (write), eol_unsupported_releases (write)
