| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__repotrending__get_repo` `mcp__repotrending__get_trending` `mcp__repotrending__list_filters` `mcp__repotrending__search_repos` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| 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 (1)

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

### `how_we_rank`

- 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
Plain explanation of how RepoTrending counts stars gained, which repos it tracks, what it leaves out and how much data each window has so far.
```

## Only reads (4)

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

### `get_repo`

- The name "get_repo" says "get": a word for reading.
- Tag private-data: The name "get_repo" says "get" and "repo": it reads repositories. The description's first sentence says "repo": it reads repositories. The input names a repo (input.repo), and the tool reads: it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Details of one tracked repo by owner/name: stars, forks, language, license, topics, star counts of the last days, gains and ranks per window.
```

### `get_trending`

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

Description, as the server wrote it:

```untrusted-server-text
Top GitHub repos by stars gained today (last 24 hours), this week (7 days) or this month (30 days), or by total stars (window "all"). Optional language or topic filter. Use list_filters for valid names.
```

### `list_filters`

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

Description, as the server wrote it:

```untrusted-server-text
List the languages or the GitHub topics that get_trending and search_repos accept, with how many tracked repos each has. Most repos first.
```

### `search_repos`

- The name "search_repos" says "search": a word for reading.
- Tag private-data: The name "search_repos" says "search" and "repo": it reads repositories. The description's first sentence says "find" and "repo": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Find tracked repos by words in the name, description, topics or language. Every word must match. Results are ordered by relevance, then stars.
```
