## 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 (5)

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

### `cheapest_gpu`

- 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
Cheapest current rental offers for one GPU family (e.g. "H100", "RTX 5090",
        "b200"), in USD per GPU-hour, cheapest first, one row per provider.
        pricing_type is "on_demand" (default; can't be interrupted) or "spot"
        (cheaper, the provider can reclaim the machine). limit: 1-10.
```

### `cheapest_model_route`

- 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
Cheapest inference providers for one LLM (e.g. "deepseek-v3", "gpt-oss-120b";
        use find_model if unsure of the name). Prices are USD per 1M tokens; estimated_cost_usd
        is for the given input/output token counts. One row per provider, cheapest first. limit: 1-10.
```

### `gpu_price_forecast`

- 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
Market-implied future rental price for one GPU family (USD per GPU-hour), from
        prediction markets (Kalshi, Polymarket) and ICE futures, plus today's compute-index
        benchmarks and cheap-gpus.com's own current median price. Covers H100, H200, B200,
        A100 and RTX 5090.
```

### `gpu_price_history`

- 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
Daily price history for one GPU family: each day's median across providers
        of each provider's cheapest offer (USD per GPU-hour). days: 1-90.
```

### `gpus_needed_for_model`

- 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
How many GPUs it takes to self-host an open-weight LLM at a given quantization,
        and the cheapest rental setups for it right now. quant is one of: fp16, bf16, fp8,
        mxfp8, int8, q6, fp6, q5, q4km, nvfp4, awq, mxfp4, gptq, int4, q3, q2, iq2, iq1.
        Estimates memory only (weights + 20% runtime overhead), not throughput. limit: 1-10.
```

## Only reads (2)

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

### `find_model`

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

Description, as the server wrote it:

```untrusted-server-text
Search the LLM catalog by name (e.g. "deepseek v3", "gpt-oss", "llama 70b").
        Returns model slugs to pass to cheapest_model_route / gpus_needed_for_model,
        most widely offered first. limit: 1-10.
```

### `list_gpu_families`

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

Description, as the server wrote it:

```untrusted-server-text
List every GPU family tracked on cheap-gpus.com, with VRAM, live cheapest
        on-demand price (USD per GPU-hour), and how many providers currently offer it.
```
