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 |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `call_api`

- The name "call_api" says "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Make a live request to a dataandapis.com API with the user's API key (sent as X-Api-Key on this MCP connection). Give the API slug, the endpoint path from get_api (path parameters already filled in, e.g. '/v1/products/3017620422003'), optional query parameters and, for POST, a JSON body. Most calls cost 1 token.
```

## Only reads (2)

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

### `get_api`

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

Description, as the server wrote it:

```untrusted-server-text
Full reference for one API: every endpoint with method, path, path and query parameters with example values, request body and an example response, plus the token cost per call. Use the slug from search_apis.
```

### `search_apis`

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

Description, as the server wrote it:

```untrusted-server-text
Find APIs on dataandapis.com by the data they provide (e.g. 'sanctions screening', 'barcode nutrition', 'IP geolocation', 'company by domain', 'public holidays'). Returns up to 10 matches with slug, one-line summary, base URL and docs. Follow with get_api for the endpoints.
```
