## 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__ai-architectures__list_my_cad_drawings` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__ai-architectures__get_design_tool_link` `mcp__ai-architectures__list_my_cad_drawings` |
| 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 `prepare_cad_drawing_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "prepare_cad_drawing_link" says "link": a word for a change.
```


## Changes things (3)

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

### `change_cad_drawing`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks to change one of their CAD drawings in words ("make the kitchen 4.2 m wide", "move the garage to the left", "add a window to bedroom 2"). The drafter makes the change as a new version (earlier versions stay in the studio). Spends credits from the user's AI Architectures account (usually 60 to 600 per change). Then call get_cad_drawing.
```

### `prepare_cad_drawing_link`

- The name "prepare_cad_drawing_link" says "link": 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
Use this when the user wants a floor plan drawn as CAD (DXF/DWG) but is not signed in to an AI Architectures account here, or prefers to continue on the website, or wants to attach a sketch there. Returns a link that opens the Plan Chat CAD studio with the request already typed in; nothing is drawn or charged until the user presses send on the site.
```

### `start_cad_drawing`

- The name "start_cad_drawing" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks to draw or design a floor plan as a real CAD drawing and wants it made now. The AI drafter of the Plan Chat CAD studio draws a layered, dimensioned plan (walls, doors, windows, furniture, dimensions, room names and areas) from the description and, if attached, a sketch or photo of a plan. Needs the user's AI Architectures account and spends credits from it (usually 700 to 1,800 credits per drawing; get_credit_balance shows the balance). Drawing takes 1 to 5 minutes; then call get_cad_drawing with the returned drawing_id. Confirm the brief with the user before starting.
```

## Only reads (8)

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

### `get_cad_drawing`

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

Description, as the server wrote it:

```untrusted-server-text
Use this to check a drawing started with start_cad_drawing (or one of list_my_cad_drawings): status, what the drafter says, room names, a preview image, the studio link and, when the account allows, DXF, DWG and PDF download links (valid for 10 minutes; call again for fresh ones). While it is still drawing this waits up to wait_seconds for it to finish.
```

### `get_credit_balance`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks how many AI Architectures credits their account has left before starting or changing a drawing.
```

### `get_design_tool_link`

- The name "get_design_tool_link" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants something AI Architectures does on its website from a photo or image: a remodel preview on a photo of their own home, a photoreal render from a sketch or model view, a render from a description, virtual staging, a listing photo kit, a clean floor plan image from a sketch or scan, a CAD drawing from a sketch, or before/after examples. Returns the page that does it; the user uploads the photo there.
```

### `get_house_plan`

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

Description, as the server wrote it:

```untrusted-server-text
Use this to show one house plan from search_house_plans in detail: description, every floor plan image and all free download links (PDF plan set, DXF per level, IFC, GLB).
```

### `get_profile`

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

Description, as the server wrote it:

```untrusted-server-text
Return the AI Architectures account behind this connection. The opaque id is the account id, unique and unchanged across token refresh, reconnection and changes to the email or name.
```

### `list_my_cad_drawings`

- The name "list_my_cad_drawings" says "list": a word for reading.
- Tag private-data: The description's first sentence says "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks about their own drawings in the Plan Chat CAD studio. Lists them newest first with id, title, number of versions and whether one is being drawn now.
```

### `search_house_plans`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants ready-made house plans, floor plan ideas or downloadable plans (for example "3 bedroom ranch under 2,000 sq ft", "small ADU", "barndominium"). Searches a library of about 500 free house plans by AI Architectures, each with a floor plan image, room sizes and free PDF, DXF, IFC and GLB downloads. Returns plan cards with links to the plan page and to change the plan in the CAD studio. Filters are optional; leave out what the user did not ask for.
```

### `show_community_cad_drawings`

- The name "show_community_cad_drawings" says "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants to see what the AI drafter draws, or examples of AI-made CAD floor plans. Lists published drawings from the Plan Chat CAD studio (real, unretouched output), each with a preview, the brief it was drawn from, a free DXF download and a link to draw a similar one.
```
