## Only reads (1)

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

### `compare_json`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when you want to compare two JSON documents, find changed JSON paths, or distinguish type changes from value changes. Ignores object key order, preserves array order, and compares decimal numbers without float rounding. Limits: 20,000 characters per document, depth 64, 4,000 values, 500 differences. Does not compare source code, YAML, JSON5, or duplicate-key documents.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__json-diff__compare_json"
    ],
    "ask": [],
    "deny": []
  }
}
```
