**12 tools: 1 can delete or cancel things, 7 change things and 4 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 1 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 7 | ask |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `scholarfetch_saved_remove`

- The name "scholarfetch_saved_remove" says "remove": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Remove one paper from a named in-memory reading list by DOI or exact title.
```

## Changes things (7)

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

### `scholarfetch_author_candidates`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Disambiguate a human author name into ranked identity candidates. Use this before `scholarfetch_author_papers` when the name is ambiguous and you need a stable `candidate_index`. If you pass `engines`, it must include `openalex`.
```

### `scholarfetch_author_papers`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Expand one author into a deduplicated paper list. This is the main author->paper traversal tool and supports research filters. Use `author_id` when you already know the exact author, or `author_name` plus `candidate_index` after `scholarfetch_author_candidates`. Supported comma-separated `filters`: year>=YYYY, year<=YYYY, year=YYYY, has:abstract, has:doi, has:pdf, venue:<text>, title:<text>, doi:<text>. If you pass `engines`, it must include `openalex`.
```

### `scholarfetch_references`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Expand a paper into its references. Use with a DOI or with author_name + candidate_index + paper_index. This is the main edge-expansion tool for traversing the literature graph. If you pass `engines`, use a comma-separated subset of: elsevier, openalex, crossref, arxiv, europepmc, springer, semanticscholar.
```

### `scholarfetch_saved_add`

- The name "scholarfetch_saved_add" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add one paper to a named in-memory reading list on the MCP server. Best input is paper_json copied from another ScholarFetch tool result, but DOI, query+result_index, or author_name+candidate_index+paper_index also work. Reuse the same collection name across calls to keep one research session together.
```

### `scholarfetch_saved_clear`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Clear all papers from a named in-memory reading list. Useful when restarting a research branch.
```

### `scholarfetch_saved_export`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Export the current reading list as citations, abstracts, BibTeX, or an aggregated full-text corpus. Valid `format` values: citations, abstracts, bib, fulltext. Valid `style` values when `format=citations`: harvard, apa, ieee. Use `include_references=true` with `format=fulltext` when you want a richer downstream synthesis corpus.
```

### `scholarfetch_search`

- The name "scholarfetch_search" says "search": a word for reading.
- The description's first verb is "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start a research traversal from keywords, a DOI, or a person name. Returns deduplicated paper records that you can inspect, save, expand through references, or use as seeds for author exploration. If you pass `engines`, use a comma-separated subset of: elsevier, openalex, crossref, arxiv, europepmc, springer, semanticscholar.
```

## Only reads (4)

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

### `scholarfetch_abstract`

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

Description, as the server wrote it:

```untrusted-server-text
Read the best abstract available for a paper. Use with a DOI or with author_name + candidate_index + paper_index after author_papers. If you pass `engines`, use a comma-separated subset of: elsevier, openalex, crossref, arxiv, europepmc, springer, semanticscholar.
```

### `scholarfetch_article_text`

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

Description, as the server wrote it:

```untrusted-server-text
Read full paper text when machine-readable content is recoverable. Use with a DOI or with author_name + candidate_index + paper_index. Uses Elsevier first, then open-access fallbacks such as Springer OA, Europe PMC, arXiv PDF, and generic PDF URLs when text is recoverable. If you pass `engines`, use a comma-separated subset of: elsevier, openalex, crossref, arxiv, europepmc, springer, semanticscholar.
```

### `scholarfetch_doi_lookup`

- The name "scholarfetch_doi_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Enrich one known DOI with metadata, reading links, and full-text availability signals. If you pass `engines`, use a comma-separated subset of: elsevier, openalex, crossref, arxiv, europepmc, springer, semanticscholar.
```

### `scholarfetch_saved_list`

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

Description, as the server wrote it:

```untrusted-server-text
List all papers currently saved in a named in-memory reading list. Use this to inspect the working set before exporting or removing items.
```

## Claude Code permissions

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 8 tools that change things (1 destructive, 7 write). Whether a call also works without credentials was not tested: tools are never called.

https://laibniz-scholarfetch-web.hf.space/mcp/: tools/list returned 12 tools to an anonymous client, including scholarfetch_saved_remove (destructive), scholarfetch_search (write), scholarfetch_author_candidates (write), scholarfetch_author_papers (write), scholarfetch_references (write) and 3 more
