## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `create_jfpi_link`

- The name "create_jfpi_link" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Creates a Just Fucking Prompt It (JFPI) link for a question someone could have asked an AI themselves. JFPI is a joke site in the spirit of "Let Me Google That For You": whoever opens the link watches the question being typed into an AI, then gets a cheeky answer in the chosen tone.

Use it only when the user asks for a JFPI or "just prompt it" link for someone else, or explicitly wants to tease another person about a question that was easy to ask an AI. Do not use it on your own initiative, and never use it to mock the user you are talking to.

Input: the other person's question, as they asked it (max 500 characters). Optional tone: mild, rude, brutal (default mild). The site checks every question; offensive or abusive ones are refused.

Returns the link and a short line in the chosen tone that you can say together with it. Give the user the link exactly as returned.
```

## Only reads (1)

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

### `list_tones`

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

Description, as the server wrote it:

```untrusted-server-text
Lists the tones a JFPI link can have (mild, rude, brutal), each with a one-line description and an example of how the answer opens. Use it when the user wants to choose how rude the link should be.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__jfpi__list_tones"
    ],
    "ask": [
      "mcp__jfpi__create_jfpi_link"
    ],
    "deny": []
  }
}
```

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

- `mcp__jfpi__create_jfpi_link`: untrusted-input
