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

### `host_promo`

- 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
Discount signals of a host: the promotion published on its site (Russian text), long-term prepayment discount computed from its own period prices, free trial and money-back days. Without a host: the hosts with the strongest discount signals. Promo codes are never invented: only those the host publishes.
```

### `vps_rating`

- 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
Top of the accsly.io VPS host rating: score 0-10 per host computed from catalog data (price per resource, entry price, trust, terms, tech, reach), with plans count and entry price. Category narrows it: cheap, russia, abroad (ru only), europe, usa, netherlands, germany, vpn (corporate VPN), windows, hourly, crypto (not on ru), game-server, or web-hosting for the shared hosting rating. Empty = overall.
```

## Only reads (5)

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

### `compare_hosts`

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

Description, as the server wrote it:

```untrusted-server-text
Like-for-like comparison of two VPS hosts from catalog data: cheapest plan with at least 1/2/4/8/16 GB RAM, plan counts, median price, countries, NVMe share, payment methods, trial, money back, hourly billing, DDoS, IPv6, SLA, rating place, and who wins on each.
```

### `get_vps_host`

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

Description, as the server wrote it:

```untrusted-server-text
Everything the catalog knows about one VPS/hosting provider: legal entity and country, server countries, payment methods, terms (trial, money back, hourly billing, DDoS, IPv6, SLA, long-term discount), place in the accsly rating, VPS price range and cheapest plan per RAM size, the cheapest plans with order links, and links to its comparison, alternatives and page.
```

### `list_offers`

- The name "list_offers" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Offers of one platform or category of the accounts catalog, across shops: price, items in stock, seller shop, product page and buy link. Pass a catalog URL (https://accsly.io/en/catalog/messengers/telegram/…), "platform/category" slugs or a platform slug.
```

### `search_accounts`

- The name "search_accounts" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "search" and "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Search the catalog of ready-made accounts (Telegram, TikTok, Gmail, Steam, ChatGPT and 70+ platforms) compared across independent shops. Returns matching platforms with their categories (slugs and URLs) and the most bought in-stock offers with price, stock, shop, product page and buy link (list_offers sorts one platform or category by price).
```

### `search_vps`

- The name "search_vps" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find VPS/VDS (or shared hosting, dedicated) plans across 2,000+ hosts by country, RAM/CPU/disk minimums, disk type, monthly budget, payment method, hourly billing and task presets. Returns 10 plans per page, cheapest first by default, each with specs, monthly price, payment methods, the host page and an order link. Prices are read on the hosts' own sites and refreshed hourly.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__catalog__search_vps",
      "mcp__catalog__get_vps_host",
      "mcp__catalog__compare_hosts",
      "mcp__catalog__search_accounts",
      "mcp__catalog__list_offers"
    ],
    "ask": [
      "mcp__catalog__host_promo",
      "mcp__catalog__vps_rating"
    ],
    "deny": []
  }
}
```

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

- `mcp__catalog__search_accounts`: private-data, untrusted-input
