## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `check_change`

- 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
Did this web page change since the last time it was checked? Hash-based change detection. First check reports 'new'; later checks report 'changed' or 'unchanged'.
```

### `check_link`

- The name "check_link" says "link": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Is this URL live right now? Returns HTTP status, the redirect chain, final URL, and round-trip latency in milliseconds.
```

### `verify`

- 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
Does this source URL support a given claim? Returns a confidence score, matched terms, and the best supporting excerpt. Heuristic term-overlap — not semantic fact-checking.
```

## Only reads (1)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get clean, readable text from a web page — boilerplate, navigation, and ads stripped — so you can work with the actual content. Returns the text plus title, content-type, HTTP status, and length.
```

## Claude Code permissions

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

  "permissions": {
    "allow": [
      "mcp__oracle__fetch"
    ],
    "ask": [
      "mcp__oracle__check_link",
      "mcp__oracle__check_change",
      "mcp__oracle__verify"
    ],
    "deny": []
