## 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

- **warn** Annotations that disagree with the tool in `request_quote_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "request_quote_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "request_quote_link" says "request": a word for a change.
```


## Changes things (1)

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

### `request_quote_link`

- The name "request_quote_link" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
A link the user opens to ask SharpSyn's suppliers for a quote on a
    compound (CAS number, InChIKey or name). Nothing is sent by calling this:
    the user fills in quantities and sends the request themselves.
```

## Only reads (3)

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

### `get_compound`

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

Description, as the server wrote it:

```untrusted-server-text
Everything SharpSyn publishes about one compound, given its CAS number,
    InChIKey or name: identifiers, structure (SMILES, InChI), number of verified
    suppliers with regions, grades and lead times, price range per kg with its
    confidence label and data date, the cradle-to-gate carbon footprint with
    tier, source and uncertainty, and the page URL to cite. If the compound has
    no public page, says so and gives a link where the user can still ask
    suppliers for it.
```

### `list_suppliers`

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

Description, as the server wrote it:

```untrusted-server-text
Suppliers listed publicly on SharpSyn (companies that asked to be listed),
    optionally only those in one country or offering one compound (CAS, InChIKey
    or name). Returns company name, country, website, number of public listings
    and the profile URL.
```

### `search_compounds`

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

Description, as the server wrote it:

```untrusted-server-text
Find compounds on SharpSyn by name, synonym, CAS number, InChIKey or
    molecular formula. Returns name, CAS, InChIKey, page URL and a summary of
    suppliers, price and carbon footprint for each match, best matches first.
```

## Claude Code permissions
