## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__research__fetch` |
| 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.


## Only reads (8)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag private-data: The description's first sentence says "retrieve" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Retrieve the public metadata document for one search ID, with source links, publication status and citation. The document is bibliographic metadata, not the publisher full text or abstract.
```

### `get_annual_statistics`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve catalogue-wide annual/status counts, missing-year totals, UTC generation time and source revision. No filters. Counts are indexed records, not independent studies or participants; current-year coverage is partial.
```

### `get_citation`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve citation text, BibTeX and RIS for one visible record ID. Retains preprint/registration status. Check the original source before citing.
```

### `get_citation_relationships`

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

Description, as the server wrote it:

```untrusted-server-text
Return a bounded set of explicit reference DOIs and indexed citing records for a visible record ID. These source-derived links are incomplete and are not proof of scientific support, criticism or trial/result identity.
```

### `get_dataset_downloads`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the current completed dataset manifest with eleven exact download URLs, SHA-256 checksums, byte sizes, count, UTC and source revision. Use for full SQLite/CSV/JSON, citations, ZIP, compact JSON, titles/years TXT or frozen statistics. Check complete and is_current; preserve files because only three snapshots are retained. This tool returns download metadata, not binary bytes or a locally attached file.
```

### `search`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find up to 20 relevant bibliographic records using keywords or identifiers; use fetch with a returned ID for complete public metadata. This bounded discovery list is not an exhaustive export. Use get_dataset_downloads for the entire catalogue.
```

### `search_publications`

- The name "search_publications" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search public publications, preprints and trial-registration records with explicit filters, total counts and pagination. Query and author are keyword searches; journal/topic/source/status filters use stored labels. Preserve distinct IDs. For exhaustive or reproducible analysis use get_dataset_downloads.
```

### `search_trials`

- The name "search_trials" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find registered clinical trials by keywords or exact country, sponsor, phase, condition or registry status. Returns bounded pages and registry observation dates. Registry statements and recruitment status are not completed treatment results; this collection overlaps trial records in publication search.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__research__search",
      "mcp__research__fetch",
      "mcp__research__search_publications",
      "mcp__research__search_trials",
      "mcp__research__get_citation",
      "mcp__research__get_citation_relationships",
      "mcp__research__get_annual_statistics",
      "mcp__research__get_dataset_downloads"
    ],
    "ask": [],
    "deny": []
  }
}
```
