## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__neuronform__list_templates` |
| 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 `create_design` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_design" 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 "create_design" says "create": a word for a change.
```

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

```untrusted-server-text
The server marks "edit_design" 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 "edit_design" says "edit": a word for a change.
```

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

```untrusted-server-text
The server marks "edit_tiles" 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 "edit_tiles" says "edit": a word for a change.

## Changes things (5)

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

### `create_design`

- The name "create_design" says "create": 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
Compiles a short brief into a complete design with the configurator defaults; the centre given by place or lat and lon is the centre of tile 0. Invalid values fall back to their defaults with a notice naming the brief field. Change the result with edit_design.
```

### `edit_design`

- The name "edit_design" says "edit": 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
Changes a design and returns the complete changed design, validated against the rules and the limits of anonymous use. changes takes brief fields (an absent field keeps the design: width, rotation, model_width, exaggeration, relief, frame, colors, label, tiles, shape, or place or lat and lon to move the centre of tile 0); patch takes JSON Patch operations for every other field, applied after changes. The service stores no design: send the complete design every time and continue with the returned one.
```

### `edit_tiles`

- The name "edit_tiles" says "edit": 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
Adds a tile at, or removes the tile at, a compass side of a tile and returns the updated design.
```

### `render_design`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Renders a design as an image, returns its summary, and opens the interactive 3D viewer where the host supports it. The default overview shows four 3D views from the north, east, south, and west beside the top view with north up and a scale bar, so proportions and relief read from every side; view top or oblique with a direction gives one larger view, resolution high doubles the size. A repeated render of the same design and options is answered from the cache.
```

### `share_design`

- The description's first verb is "store": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Stores the design and returns a link, valid for 90 days, that opens exactly this design in the NeuronForm configurator.
```

## Only reads (5)

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

### `find_map_elements`

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

Description, as the server wrote it:

```untrusted-server-text
Lists roads and paths, buildings, areas, or ground regions of the design with a ready-to-insert request fragment and its target path; a building also carries the placement of a custom house that replaces it.
```

### `get_design_guide`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the guide of one topic of the design JSON with the JSON schema of its fields.
```

### `list_templates`

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

Description, as the server wrote it:

```untrusted-server-text
Lists published gallery templates with slug, title, and image URL; with a slug it returns the design of that template.
```

### `search_places`

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

Description, as the server wrote it:

```untrusted-server-text
Searches places, streets, and house numbers in the place index of NeuronForm and returns candidates with name, lat, lon, and kind.
```

### `validate_design`

- The name "validate_design" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Checks a design against the request rules, the limits of anonymous use, and the restricted areas without generating it.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `neuronform`:

```json

  "permissions": {
    "allow": [
      "mcp__neuronform__search_places",
      "mcp__neuronform__get_design_guide",

      "mcp__neuronform__share_design"
    ],
    "deny": []
  }
}
```
