## 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 (1)

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

### `estimate_quantization_energy`

- 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
Estimate the task-level energy change (ΔE% vs FP16) of weight-only quantization (NF4 or INT8) for a model of a given size on a GPU architecture class, from measured-anchored curves. The answer carries basis (measured/interpolated/estimated), confidence and evidence boundaries.
```

## Only reads (3)

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

### `get_quantization_crossover`

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

Description, as the server wrote it:

```untrusted-server-text
Get the model-size crossover for NF4/INT8 per architecture: below it quantization costs energy, above it saves. Crossovers belong to a card + software stack, not an architecture — the answer says so.
```

### `list_data_coverage`

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

Description, as the server wrote it:

```untrusted-server-text
List what is actually measured (GPU architecture × precision × size range, NVML direct), what is borrowed/estimated, and where the gaps are. Use this before trusting an estimate at the edges of coverage, and to answer 'is there data for my GPU?' honestly.
```

### `search_measurements`

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

Description, as the server wrote it:

```untrusted-server-text
Search the measured anchors by model name, GPU name, architecture or size. Returns ΔE% vs FP16 per anchor with run counts — the raw evidence behind the curves.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__ecocompute-estimator__get_quantization_crossover",
      "mcp__ecocompute-estimator__list_data_coverage",
      "mcp__ecocompute-estimator__search_measurements"
    ],
    "ask": [
      "mcp__ecocompute-estimator__estimate_quantization_energy"
    ],
    "deny": []
  }
}
