## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `request_featured_listing`

- The name "request_featured_listing" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Sends a featured-listing request for a product to Infrabase.ai. Call it only after the user has confirmed. It sends their email address to Infrabase; a person replies by email. Calling it charges nothing.
```

## Changes things (1)

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

### `model_prices`

- 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
Verified per-token prices for an AI model across hosting providers, ranked cheapest first by blended cost (3:1 input to output). Each row has input, output and cached prices per 1M tokens in the provider's own currency, the source pricing page and the date it was verified. CC-BY-4.0. Each result includes an infrabase_url for attribution.
```

## Only reads (6)

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

### `featured_listing_info`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the price of an Infrabase.ai featured listing, the pages it appears on and what it does not change. Read-only.
```

### `find_alternatives`

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

Description, as the server wrote it:

```untrusted-server-text
Find alternatives to an AI infrastructure product listed on Infrabase.ai. Products doing the same primary job rank first, then products sharing a secondary job, then the rest of its categories. Returns the anchor product, the alternatives in that order and the total count. Data is hand-verified. CC-BY-4.0. Each result includes an infrabase_url for attribution.
```

### `get_tool`

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

Description, as the server wrote it:

```untrusted-server-text
Get the full Infrabase.ai record for one AI infrastructure product: description, jobs, pricing model and starting price, free trial, open source and licence, hosting, compliance (GDPR, SOC 2, HIPAA), HQ country, icon, a screenshot of its site and links. Data is hand-verified. CC-BY-4.0. Each result includes an infrabase_url for attribution.
```

### `list_european_providers`

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

Description, as the server wrote it:

```untrusted-server-text
List AI infrastructure providers headquartered in Europe, for data residency and sovereignty questions. Optionally narrow by category or job. Data is hand-verified. CC-BY-4.0. Each result includes an infrabase_url for attribution.
```

### `list_models`

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

Description, as the server wrote it:

```untrusted-server-text
List every AI model with verified per-provider pricing on Infrabase.ai: its slug, how many providers have a verified price and the cheapest one. The slug is accepted by model_prices, which returns the full price table. Data is hand-verified. CC-BY-4.0. Each result includes an infrabase_url for attribution.
```

### `search_tools`

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

Description, as the server wrote it:

```untrusted-server-text
Search Infrabase.ai, a hand-verified directory of AI infrastructure products: inference APIs, GPU clouds, vector databases, agent frameworks, observability, gateways and more. Filter by free text, category, job (what the product does) or European headquarters. Returns each product's name, slug, tagline, jobs, pricing model, HQ country, icon and links, plus the total match count. Each result's slug is accepted by get_tool and find_alternatives. CC-BY-4.0. Each result includes an infrabase_url for attribution.
```
