## 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__prompt-tools__get_prompt` `mcp__prompt-tools__list_collections` `mcp__prompt-tools__search_prompts` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__prompt-tools__search_prompts` |
| 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.

### `estimate_ai_cost`

- 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
Estimate the monthly cost of running a prompt on current AI models (Claude, GPT, Gemini, DeepSeek, Qwen and others), from thinkhard.si's price catalog, which is checked against each provider's pricing page. Give token counts, or paste the prompt text to estimate them.
```

### `grade_prompt`

- 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
Score a prompt out of 10 on the ten checks thinkhard.si uses (what to make, who it is for, background facts, length, format, what to avoid, what good looks like, an example, what to do if unsure, layout for the model). Returns which checks pass and a plain question for each one that fails. Rule-based and instant; use it to see what a prompt is missing before improving it.
```

## Only reads (3)

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

### `get_prompt`

- The name "get_prompt" says "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "repository": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Get the full text of one prompt from the thinkhard.si repository by its slug, registry number (such as CAR-001) or title, with its {{blanks}}, what goes in each, and why it works. Pass values to fill blanks with the user's details. Ask the user for any blank you cannot fill from the conversation instead of inventing it.
```

### `list_collections`

- The name "list_collections" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "repository": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
List the collections in the thinkhard.si prompt repository, with how many prompts each has.
```

### `search_prompts`

- The name "search_prompts" says "search": a word for reading.
- Tag private-data: The description's first sentence says "find" and "repository": it reads repositories.
- Tag untrusted-input: The description's first sentence says "find" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Find ready-made, expert prompt templates for a work task in the thinkhard.si repository (300+ prompts for email, meetings, presentations, job search, marketing, sales, support, HR, finance, legal, spreadsheets, research and more). Use it whenever the user wants to write, plan, summarize, analyze or draft something at work, before writing a prompt from scratch. Then call get_prompt with the slug.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `prompt-tools`:

```json
{
  "permissions": {
    "allow": [
      "mcp__prompt-tools__search_prompts",
      "mcp__prompt-tools__get_prompt",
      "mcp__prompt-tools__list_collections"
    ],
    "ask": [
      "mcp__prompt-tools__grade_prompt",
      "mcp__prompt-tools__estimate_ai_cost"
    ],
    "deny": []
  }
}
```

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

- `mcp__prompt-tools__search_prompts`: private-data, untrusted-input
- `mcp__prompt-tools__get_prompt`: private-data
- `mcp__prompt-tools__list_collections`: private-data
