## 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__vendorindex__get_vendor` |
| 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.

### `recommend`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Recommend the top vendors for a specific category + use case, with the reasoning (which dimensions drove the pick). Best when an agent needs a single answer to 'what should I use for X?'.
```

## Only reads (5)

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

### `compare_vendors`

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

Description, as the server wrote it:

```untrusted-server-text
Side-by-side comparison of several vendors for one category + use case: weighted totals, per-dimension scores and health trend. Use for head-to-head questions.
```

### `get_category_ranking`

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

Description, as the server wrote it:

```untrusted-server-text
Get the ranked vendors for a category, scored per use case (deterministic, from verified pricing + agent-friction + health). Omit use_case to get the ranking for every use case in the category. Returns each vendor's weighted total and per-dimension scores.
```

### `get_vendor`

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

Description, as the server wrote it:

```untrusted-server-text
Full detail for one vendor: cited pricing (structured rates + source URL + verified date + confidence), agent-friction checks, SDKs, capabilities, portability and health signals.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
List every vendor category VendorIndex covers (e.g. transactional-email, llm-models, embeddings-apis, llm-gateways), each with its use cases and vendor count. Call this first to discover valid category and use_case ids.
```

### `search_vendors`

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

Description, as the server wrote it:

```untrusted-server-text
Find vendors by free-text query across name, id, category and capability (e.g. 'embedding', 'soc2', 'fast_inference'). Returns matches with their categories.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__vendorindex__list_categories",
      "mcp__vendorindex__get_category_ranking",
      "mcp__vendorindex__get_vendor",
      "mcp__vendorindex__compare_vendors",
      "mcp__vendorindex__search_vendors"
    ],
    "ask": [
      "mcp__vendorindex__recommend"
    ],
    "deny": []
  }
}
```

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

- `mcp__vendorindex__get_vendor`: untrusted-input
