## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `cheapest_provider`

- 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
Every provider serving a model, sorted by input price per 1M tokens (refreshed daily from provider endpoints), with output price, quantization and 1 day uptime.
```

### `latest_findings`

- 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
Latest notable results detected in the Gecko Tests and price data (fixed rules, numbers and quotes from stored results).
```

## Only reads (7)

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

### `compare_models`

- The name "compare_models" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Side by side: BenchGecko score, list price, cheapest provider, context window, shared benchmark scores and Gecko Tests grades for two models.
```

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch the full record for an id returned by search (model:<slug>, gecko-test:<slug> or scorecard).
```

### `get_gecko_test`

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

Description, as the server wrote it:

```untrusted-server-text
Results of one of BenchGecko's own tests (own measurements, CC BY 4.0): who-are-you (Does the model know which lab made it?) world-map (How well does the model draw the world map from memory?) censorship-index (How often does the model refuse legitimate questions?) knowledge-horizon (Where does the model's knowledge of world events actually stop?) tokenizer-tax (How many more tokens does the same text cost outside English?) same-model-different-host (Do providers serving the same open model give the same quality?) model-drift-index (Do models quietly change behind the same name?)
```

### `get_model`

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

Description, as the server wrote it:

```untrusted-server-text
Core facts for one AI model: BenchGecko score and rank, list price, price at every provider, benchmark scores with their original sources, Gecko Tests grades and as-of dates.
```

### `get_scorecard`

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

Description, as the server wrote it:

```untrusted-server-text
BenchGecko Gecko Scorecard: every model across BenchGecko's own profile tests with a letter grade per test and an overall Gecko Score (behavior, not intelligence).
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Search BenchGecko models and Gecko Tests. Returns ids for fetch.
```

### `search_models`

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

Description, as the server wrote it:

```untrusted-server-text
Find AI models in the BenchGecko catalog by name, slug or lab. Returns slugs to use with get_model, cheapest_provider and compare_models, with BenchGecko score and list price.
```
