## 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__catalog__search_startups` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__catalog__get_startup` `mcp__catalog__get_stats` `mcp__catalog__list_categories` |
| 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 (1)

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

### `check_if_listed`

- 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
Check whether a company appears in the directory (name or slug contains the text). When it does not, the result says how a person can get it listed.
```

## Only reads (5)

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

### `get_startup`

- The name "get_startup" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "get" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Get one listed company by slug (or exact name): every public field plus its page URL.
```

### `get_stats`

- The name "get_stats" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The list in numbers: five aggregates of the listed companies (category, funding stage, headquarters, founded year, minimum disclosed funding), each with n, coverage, caveat, method, as-of date, CSV and chart URL. CC BY 4.0 with attribution.
```

### `get_stats_history`

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

Description, as the server wrote it:

```untrusted-server-text
Quarterly snapshots of the same aggregates and one series per chart across snapshots. Never interpolated: one snapshot is one point. CC BY 4.0 with attribution.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
List every security-company category with its slug, description, company count and page URL.
```

### `search_startups`

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

Description, as the server wrote it:

```untrusted-server-text
Search the Security Startups directory of young security companies. Filters combine with AND. Returns public fields and each company's page URL, alphabetical by name (not a ranking).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__catalog__search_startups",
      "mcp__catalog__get_startup",
      "mcp__catalog__list_categories",
      "mcp__catalog__get_stats",
      "mcp__catalog__get_stats_history"
    ],
    "ask": [
      "mcp__catalog__check_if_listed"
    ],
    "deny": []
  }
}
```

- `mcp__catalog__search_startups`: private-data
- `mcp__catalog__get_startup`: untrusted-input
- `mcp__catalog__list_categories`: untrusted-input
