## Findings

No check matched anything in these tool definitions.


## Only reads (5)

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

### `readgzh.get`

- The name "readgzh.get" says "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "get" and "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Get a cached WeChat article by its short slug/URL path via ReadGZH. Use when you have a slug like 'minicpm-o-4-5' from a previous read.
```

### `readgzh.list`

- The name "readgzh.list" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "list" and "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List recently cached WeChat articles via ReadGZH. Returns titles, authors, and links. Useful for browsing what articles have been previously read and cached.
```

### `readgzh.list_by_account`

- The name "readgzh.list_by_account" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "list" and "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List cached WeChat articles published by one Official Account (公众号) via ReadGZH. IMPORTANT: this only covers articles already cached by ReadGZH — WeChat has no public API for a full account archive, so the result is not exhaustive. Use it to find other articles by the same author after reading one.
```

### `readgzh.read`

- The name "readgzh.read" says "read": a word for reading.
- Tag private-data: The description's first sentence says "read" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "read" and "chat": it reads messages, which other people can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Read and extract the full text content of a WeChat Official Account (微信公众号) article via ReadGZH (readgzh.site). Provide a WeChat article URL and get back the title, author, publish time, and full article text in Markdown format. The article will be automatically cached for future reads.
```

### `readgzh.search`

- The name "readgzh.search" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "search" and "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Search cached WeChat articles by keyword via ReadGZH. Searches in article titles and content. Returns matching articles with snippets.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__readgzh__readgzh_list",
      "mcp__readgzh__readgzh_search",
      "mcp__readgzh__readgzh_list_by_account",
      "mcp__readgzh__readgzh_get"
    ],
    "ask": [
      "mcp__readgzh__readgzh_read"
    ],
    "deny": []
  }
}
```

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

- `mcp__readgzh__readgzh_read`: private-data, untrusted-input, outbound
- `mcp__readgzh__readgzh_list`: private-data, untrusted-input
- `mcp__readgzh__readgzh_search`: private-data, untrusted-input
- `mcp__readgzh__readgzh_list_by_account`: private-data, untrusted-input
- `mcp__readgzh__readgzh_get`: private-data, untrusted-input
