## 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__marketplace__get_bundle_manifest` |
| 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 (9)

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

### `fetch`

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

Description, as the server wrote it:

```untrusted-server-text
Read one Graunt catalog packet by id. Returns its title, description, price and whether an account is needed, its seller-declared rights, and its public URL. A free packet that needs no account also returns its files: small text files (CSV, JSON, Markdown, text and similar) in the text, and a short-lived download link for each listed file in metadata.files (at most 100 per fetch; files_not_listed counts the rest). Images, audio and video carry no link and download from the packet's public URL.
```

### `get_agent_commerce_manifest`

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

Description, as the server wrote it:

```untrusted-server-text
Read the agent commerce manifest for a listing: price, rights, and how to buy it.
```

### `get_asset`

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

Description, as the server wrote it:

```untrusted-server-text
Read a single listing by id. Public projection.
```

### `get_asset_manifest`

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

Description, as the server wrote it:

```untrusted-server-text
Read the canonical asset manifest (sha256-stamped).
```

### `get_bundle_manifest`

- The name "get_bundle_manifest" says "get": a word for reading.
- Tag private-data: The description's first sentence says "read" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Read the per-asset bundle inventory: every delivered file with role, format, size and content hash, plus counts that name the population each one counted.
```

### `meta_capabilities`

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

Description, as the server wrote it:

```untrusted-server-text
Read /v1/meta/capabilities — the authoritative capability state map.
```

### `meta_refinery_support_matrix`

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

Description, as the server wrote it:

```untrusted-server-text
Read /v1/meta/refinery-support-matrix: the source types Graunt accepts and what the Refinery does with each. Every upload gets deterministic extraction; a model drafts only the listing fields a seller leaves empty.
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Search the Graunt catalog of evaluated data packets. Returns matching packets with their id, title, and public URL.
```

### `search_assets`

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

Description, as the server wrote it:

```untrusted-server-text
Search the public catalog of evaluated packets and listings. Returns paginated matches.
```

## Claude Code permissions
