## 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

No check matched anything in these tool definitions.


## Changes things (2)

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

### `calculate_takeoff`

- 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
Calculate an auditable material takeoff from explicit geometry or a
    supported SmartScale/ProtoGen measurement payload. Returns net, explicit
    waste-adjusted, and conservative purchase quantities. This is a planning
    estimate, not a guaranteed material order or professional certification.
```

### `verify_result`

- 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
Recompute a takeoff audit hash, notary payload, pack currency, and QT9
    unit-resolved conservation. Pass the prior result object as JSON.
```

## Only reads (5)

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

### `describe_agent`

- The name "describe_agent" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return fleet-standard capabilities, version, pack digest, disclaimer,
    composition role, and pricing.
```

### `get_assembly`

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

Description, as the server wrote it:

```untrusted-server-text
Return one assembly's formula, required dimensions, material factors,
    purchase increment, sources, and material-pack lineage.
```

### `get_material_pack`

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

Description, as the server wrote it:

```untrusted-server-text
Return the bundled factors, densities, coverages, waste defaults,
    purchase increments, unit conversions, sources, and raw-pack SHA.
```

### `list_assemblies`

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

Description, as the server wrote it:

```untrusted-server-text
List supported assemblies, required dimensions, formulas, waste
    defaults, and the current material-pack digest.
```

### `list_material_pack`

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

Description, as the server wrote it:

```untrusted-server-text
List the bundled material pack version, digest, coverage, shapes,
    rebar sizes, roof pitches, and explicit unsupported policy.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `quantity-takeoff`:

```json
{
  "permissions": {
    "allow": [
      "mcp__quantity-takeoff__list_assemblies",
      "mcp__quantity-takeoff__get_assembly",
      "mcp__quantity-takeoff__list_material_pack",
      "mcp__quantity-takeoff__get_material_pack",
      "mcp__quantity-takeoff__describe_agent"
    ],
    "ask": [
      "mcp__quantity-takeoff__calculate_takeoff",
      "mcp__quantity-takeoff__verify_result"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:23:36.478Z, unchanged since 2026-10-22T15:23:36.478Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.viridisconservation.com/quantity-takeoff/mcp: tools/list returned 7 tools to an anonymous client, including calculate_takeoff (write), verify_result (write)
