## 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.


## Only reads (11)

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

### `describe_taxonomy`

- The name "describe_taxonomy" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the values Rösti uses for IOC types, IOC tags (with descriptions),
IOC categories and export formats, and explain the false-positive risk
scale. Use these values for the filters of the search and list tools.
```

### `find_related_reports`

- The name "find_related_reports" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find other Rösti reports that share IOCs with one report, most shared
IOCs first, with the shared values.
```

### `get_export_link`

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

Description, as the server wrote it:

```untrusted-server-text
Get a download link for one report export, e.g. CSV or MISP.

The link is signed and expires after 15 minutes; it is meant to be opened by
the user, not downloaded here.
```

### `get_report`

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

Description, as the server wrote it:

```untrusted-server-text
Get one Rösti report: metadata, MITRE ATT&CK ids, CVEs, available export
formats, and how many of its IOCs there are per type and per tag.

Use list_report_iocs for the IOCs themselves and get_yara_rules for its
YARA rules.
```

### `get_yara_rules`

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

Description, as the server wrote it:

```untrusted-server-text
Get the YARA rules published with one Rösti report, with their full source.
```

### `list_report_iocs`

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

Description, as the server wrote it:

```untrusted-server-text
List the IOCs of one Rösti report, optionally filtered by type, tag,
category or text.

IOCs with the same entity_ref belong together, e.g. the MD5, SHA-1 and
SHA-256 of one file. Each IOC carries its IDS flag and false-positive risk.
```

### `list_sources`

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

Description, as the server wrote it:

```untrusted-server-text
List the publishers whose reports Rösti collects (vendor blogs, CERTs,
researchers), with report counts, the newest report date and whether the
source is still active. Source ids work as the sources filter of
search_reports.
```

### `lookup_ioc`

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

Description, as the server wrote it:

```untrusted-server-text
Check whether one IOC (indicator of compromise) appears in Rösti's
threat-intelligence reports.

A defanged value (hxxps://evil[.]com, 1.2.3[.]4) is refanged before the
lookup; `input` then shows the value as given. Matching is exact, with a
case-insensitive fallback. Returns every report the value appears in (newest
first, up to max_matches) with the IOC's type, category, tags, IDS flag,
comment and false-positive risk.
```

### `lookup_iocs`

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

Description, as the server wrote it:

```untrusted-server-text
Check many IOCs (indicators of compromise) at once against Rösti's
threat-intelligence reports.

Defanged values (hxxps://evil[.]com, 1.2.3[.]4, user[at]evil[.]com) are
refanged before the lookup; `refanged` shows which. Matching is exact, with a
case-insensitive fallback. For each value that is found, returns the reports
it appears in (newest first) with the IOC's type, category, tags, IDS flag,
comment and false-positive risk. Values that are not found are listed in
`not_found`. Use lookup_ioc for all matches of a single value.
```

### `search_iocs`

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

Description, as the server wrote it:

```untrusted-server-text
Search IOCs across all Rösti reports by text, type, tag, category and
creation time. Without filters, lists IOCs from all reports.

Each IOC carries its report id (use get_report for the report), type,
category, tags, IDS flag, comment and false-positive risk. Use lookup_ioc
or lookup_iocs to check whether specific values are known.
```

### `search_reports`

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

Description, as the server wrote it:

```untrusted-server-text
Search Rösti's threat-intelligence reports by text, source, CVE, MITRE
ATT&CK id and publication date.

Returns report summaries: title, date, source, authors, tags, counts of IOCs,
YARA rules and MITRE ids, and links to the original report and rosti.dev.
Use get_report for the details of one report.
```
