## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__aspicio__describe_doc` `mcp__aspicio__view_dxf` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__aspicio__describe_doc` `mcp__aspicio__describe_dxf` `mcp__aspicio__describe_pdf` `mcp__aspicio__load_dxf_for_viewer` `mcp__aspicio__render_doc` `mcp__aspicio__render_dxf` `mcp__aspicio__render_pdf` `mcp__aspicio__view_dxf` |
| 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 `view_dxf` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":true}; The name "view_dxf" says "view": a word for reading.
```


## Changes things (5)

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

### `load_dxf_for_viewer`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Internal: returns DXF bytes (base64) for the in-chat viewer. Called by the widget, not the model.
```

### `render_doc`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Render a drawing in any supported format (DXF or PDF) to a PNG you can look at, detected from its bytes rather than its name. Use this when you do not know which format you have. Renders the first page/sheet by default; pass `space` (a name from a describe reply's `spaces`) to render another one. Some chat UIs do not display the returned image to the user: for URL sources the result also includes a direct image link — show it (e.g. as a markdown image) when they need to see the render. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
```

### `render_dxf`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Render a DXF drawing to a PNG image you can look at. Use this to answer visual questions (what does it look like, where is a feature, does it look right) — it returns an image, not text. For structural facts, prefer describe_dxf. For a PDF use render_pdf; if you do not know the format, use render_doc. Renders the first page/sheet by default; pass `space` (a name from a describe reply's `spaces`) to render another one. Some chat UIs do not display the returned image to the user: for URL sources the result also includes a direct image link — show it (e.g. as a markdown image) when they need to see the render. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
```

### `render_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Render a PDF drawing's vector content to a PNG you can look at. Images, shadings, and transparency are not drawn — they are reported by describe_pdf — so this shows line work and text, not a page facsimile. For a DXF use render_dxf; if you do not know the format, use render_doc. Renders the first page/sheet by default; pass `space` (a name from a describe reply's `spaces`) to render another one. Some chat UIs do not display the returned image to the user: for URL sources the result also includes a direct image link — show it (e.g. as a markdown image) when they need to see the render. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
```

### `view_dxf`

- The name "view_dxf" says "view": a word for reading.
- The description's first verb is "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag private-data: The description's first sentence says "chat": it reads messages. The input names a file (input.allow_file_open), and the tool reads: it reads files.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "open" and "chat": it reads messages, which other people can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Open an interactive viewer the user can pan, zoom, and toggle layers in (renders in-chat on MCP Apps-capable hosts). Reads DXF and vector PDF; for a PDF it shows line work and text rather than a page facsimile, so images, shadings, and transparency are absent by design. Use this when the user wants to see or explore the drawing themselves; for your own analysis use a describe_* tool (facts) or a render_* tool (image). The viewer shows only the drawing from this call. Delivery is handled by the widget itself: small drawings are embedded in the result and larger URL-sourced drawings are fetched by the widget through its own tool call — never re-fetch or inline the file for the viewer's sake, and don't blind-retry if the user reports an empty viewer (the viewer posts its actual status back to the conversation context).
```

## Only reads (3)

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

### `describe_doc`

- The name "describe_doc" says "describe": a word for reading.
- Tag private-data: The name "describe_doc" says "describe" and "doc": it reads documents.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Return a structured JSON summary of a drawing in any supported format (DXF or PDF), detected from its bytes rather than its name. Use this when you do not know which format you have; the reply names the format that was read. Covers the whole drawing by default, including every page of a multi-page PDF; pass `space` (a name from the reply's `spaces`) to scope it to one page or sheet. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
```

### `describe_dxf`

- The name "describe_dxf" says "describe": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Return a structured JSON summary of a DXF drawing — units, bounding box, layers (with the color actually drawn), per-type entity counts, and any skipped/unsupported types. Use this to answer structural questions (what layers exist, how many parts, what size, is it to scale) without rendering an image. For a PDF use describe_pdf; if you do not know the format, use describe_doc. Covers the whole drawing by default, including every page of a multi-page PDF; pass `space` (a name from the reply's `spaces`) to scope it to one page or sheet. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
```

### `describe_pdf`

- The name "describe_pdf" says "describe": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Return a structured JSON summary of a PDF drawing — units (points), bounding box, layers, per-type entity counts, the text it contains, and what was skipped (images, shadings, transparency). Use this for structural questions about a PDF without rendering it. For a DXF use describe_dxf; if you do not know the format, use describe_doc. Covers the whole drawing by default, including every page of a multi-page PDF; pass `space` (a name from the reply's `spaces`) to scope it to one page or sheet. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.

https://aspicio-api.frontsail.app/mcp: tools/list returned 8 tools to an anonymous client, including render_dxf (write), render_pdf (write), render_doc (write), view_dxf (write), load_dxf_for_viewer (write)
