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

### `discover_capabilities`

- The description's first verb is "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the capabilities.txt registry for sites that can do something — by capability id, keyword, or category. Returns matching capabilities with the site that offers them and its conformance grade. To invoke, fetch that site's /capabilities.txt.
```

### `get_site`

- The name "get_site" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the full list of capabilities a site declares, by domain.
```

### `list_sites`

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

Description, as the server wrote it:

```untrusted-server-text
List every site that publishes a conformant capabilities.txt, with its grade and capability count.
```
