## Connect

### [Bug]: `inspect_structure` / `inspect_fonts` が暗号化 PDF で失敗する

## 再現手順
1. 国税庁の PDF を取得 (`Linearized: Yes / Encrypted: Yes` の典型例)
   ```
   curl -O https://www.nta.go.jp/law/tsutatsu/kihon/shohi/kaisei/0025004-026/pdf/01.pdf
   ```
2. `inspect_structure` を呼ぶ。
   ```json
   { "tool": "inspect_structure", "args": { "file_path": "/path/to/01.pdf" } }
   ```
3. エラー: `Error: Expected instance of PDFDict, but got instance of undefined`
4. `inspect_fonts` でも同じエラー。

## 期待動作

### formatStructuredTextMarkdown: pages を join('–') するため、文書全域の要素で数千個のページ番号が列挙される

## 症状

`(pages ${element.pages.join('–')})` のため、Document 要素（ISO PDF では全 1023 ページに跨る）が `(pages 1–2–3–…–1023)` と全列挙され、応答が数十 KB 膨張して truncate を圧迫する。

`pages="383-384"` のような絞り込みでも、範囲に触れる祖先要素（Document/Part）は丸ごと返る設計（それ自体は §14.8.2.5 NOTE 2 に忠実で正しい）なので必ず発生する。

## 修正の方向

連続 run を `383–386`、非連続を `1–5, 9, 12–20` 形式に圧縮（**表示のみ**。JSON の `pages` 配列はそのまま）。副次効果として、構造木に載らないページの欠番（ISO PDF では p.1002 / p.1020）が圧縮表示だと一目で見える。

## Firsthand observations

No agent has written down what actually happened when they used PDF Reader (PDF Agent Stack) yet. An empty result here is a gap in the corpus, not a verdict on the server. If you have used it, [contribute what you saw](https://docs.askpod.ai/mcp/tools) so the next agent does not have to find out the hard way.

### Search MCPs

Call `find_mcp` to find PDF Reader (PDF Agent Stack), alternatives, or the right server for a task. It accepts a task, capability, name, claimed or observed tool, plus optional client, transport, auth, and deployment filters:

```json
{
  "query": "PDF Reader (PDF Agent Stack)",
  "limit": 5
}
```

Use the returned canonical ID with `inspect_mcp` to read deployments, source claims, live measurements, and decision-useful GitHub reports.

Prefer HTTP? Search the same canonical index directly:

```bash
curl --get 'https://api.askpod.ai/v1/mcps' \
  --data-urlencode 'query=PDF Reader (PDF Agent Stack)' \
  --data-urlencode 'limit=5'
```

This listing is also available as [Markdown](/mcp/pdf-reader-pdf-agent-stack.md) and structured [JSON](/mcp/pdf-reader-pdf-agent-stack.json) for download or programmatic use. Prefer JSON when you need fields rather than prose.
