## 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__appfinder__list_categories` `mcp__appfinder__search_apps` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__appfinder__prepare_listing` |
| 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.

### `category_demand`

- 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
The public demand report of a category: the share of buyers who asked the advisor for each feature, integration, security need and budget in the last 90 days (anonymous totals), and how many listed apps answer each.
```

### `check_listing`

- 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
Whether a website already has a published AppFinder listing, and its page. Call this before prepare_listing.
```

### `prepare_listing`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
For a maker who wants to list their own app: fills in AppFinder's submission form from what they told you plus the app's website, and returns a private link. The person opens it, signs in, reviews every field and submits; nothing is published until AppFinder's team approves it. Listing is free. Pass only what the maker said; leave out what you don't know (the website fills the gaps).
```

### `recommend_apps`

- 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
Ranks the apps in the AppFinder directory against a plain-language request and explains each pick with cited facts (what fits, what's missing, which apps a must-have rules out), plus one follow-up question that would narrow the list.
```

## Only reads (5)

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

### `compare_apps`

- The name "compare_apps" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Side by side: pricing, and the features, integrations and platforms both apps have or only one has.
```

### `find_alternatives`

- The name "find_alternatives" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Apps that do what an app does (same category, most shared features first), and what buyers who wanted to replace it chose.
```

### `get_app`

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

Description, as the server wrote it:

```untrusted-server-text
One app's listing: description, categories, pricing, platforms, features, integrations, rating and its facts with sources.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
The directory's categories with how many apps each lists.
```

### `search_apps`

- The name "search_apps" says "search": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Full-text search of the directory by name, keyword or job (most relevant first).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__appfinder__search_apps",
      "mcp__appfinder__get_app",
      "mcp__appfinder__compare_apps",
      "mcp__appfinder__find_alternatives",
      "mcp__appfinder__list_categories"
    ],
    "ask": [
      "mcp__appfinder__recommend_apps",
      "mcp__appfinder__category_demand",
      "mcp__appfinder__check_listing",
      "mcp__appfinder__prepare_listing"
    ],
    "deny": []
  }
}
```

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

- `mcp__appfinder__search_apps`: private-data
- `mcp__appfinder__list_categories`: private-data
- `mcp__appfinder__prepare_listing`: untrusted-input

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

https://appfinder.tech/api/mcp: tools/list returned 9 tools to an anonymous client, including recommend_apps (write), category_demand (write), check_listing (write), prepare_listing (write)
