## 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__keywords__request_keywords` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `keyword_top_pins` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "keyword_top_pins" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "keyword_top_pins" says "pin": a word for a change.
```

- **warn** Annotations that disagree with the tool in `niche_top_pins` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "niche_top_pins" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "niche_top_pins" says "pin": a word for a change.
```


## Changes things (6)

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

### `keyword_top_pins`

- The name "keyword_top_pins" says "pin": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The best-performing pins ranking for a keyword, by saves, with their titles, links and save counts — what is winning that search right now. est_clicks is an ESTIMATE derived from saves (Pinterest does not publish clicks or impressions for pins you do not own); pins_analysed, saves and competition are measured from the pins we crawled. Needs the Pro plan or above.
```

### `my_quota`

- 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
Your PinPinterest plan, how many lookups you have used this month and when they reset. Free — uses no lookup.
```

### `niche_top_pins`

- The name "niche_top_pins" says "pin": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The best-performing pins across a whole niche (use list_niches for the slugs), sorted and paged. Pass next_cursor back as cursor for the next page. There is no impressions sort: Pinterest does not publish impressions for pins you do not own, so we do not invent them. Needs the Pro plan or above.
```

### `related_keywords`

- 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
Keywords that appear on the same ranking pins as yours, strongest overlap first — the ones worth targeting next. Each comes with how many pins it shares and its own competition. Needs the Starter plan or above.
```

### `request_keywords`

- The name "request_keywords" says "request": a word for a change.
- Tag untrusted-input: The description's first sentence says "crawl": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Ask PinPinterest to crawl Pinterest for keywords it has no data for yet — offer this after keyword_lookup answers tracked:false, especially for a list. Pass up to 25 terms; each comes back with a request_id and a status (queued, crawling, ready, failed). Crawls usually land within 10–40 minutes and the person gets ONE e-mail when they are in; asking keyword_lookup again after crawl.retry_after_minutes returns the data. Asking twice for the same term is the same request. Uses no lookup; up to 25 new keywords a day per account. Needs the Starter plan or above.
```

### `trending`

- 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
Topics rising in a niche right now, read from the pins people are publishing this month, with example pins. Use list_niches for the slugs.
```

## Only reads (2)

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

### `keyword_lookup`

- The name "keyword_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Pinterest data for one keyword: how many ranking pins we analysed, their average and total saves, competition (low/medium/high) and an opportunity score, plus its niche. est_clicks is an ESTIMATE derived from saves (Pinterest does not publish clicks or impressions for pins you do not own); pins_analysed, saves and competition are measured from the pins we crawled. A keyword we do not hold returns tracked:false with close suggestions and does not use a lookup. Its crawl field says what happens next: on a paid plan we have already started crawling it (crawl.status queued or crawling) — tell the person to ask again in crawl.retry_after_minutes, or that we e-mail them when it is in. When several keywords come back tracked:false, offer request_keywords to queue them all in one call.
```

### `list_niches`

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

Description, as the server wrote it:

```untrusted-server-text
The niche slugs the other tools accept (niche_top_pins, trending). Free — uses no lookup.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__keywords__keyword_lookup",
      "mcp__keywords__list_niches"
    ],
    "ask": [
      "mcp__keywords__request_keywords",
      "mcp__keywords__related_keywords",
      "mcp__keywords__keyword_top_pins",
      "mcp__keywords__niche_top_pins",
      "mcp__keywords__trending",
      "mcp__keywords__my_quota"
    ],
    "deny": []
  }
}
```
