## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_api_health`

- 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
The last measured liveness of free public data APIs (weather, geo, finance, knowledge, news, public-health and developer APIs): HTTP status and latency from one read-only GET per API, with the generated_at of that measurement. status SLOW means the API timed out at 10s and answered a 45s re-probe (works, not fast); DOWN means no answer within 45s; SKIP means the API needs a key and was not called. counts.measured excludes SKIP rows, so it is the health denominator, not counts.total. It does not measure AI model provider APIs.
```

## Only reads (2)

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

### `find_free_inference`

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

Description, as the server wrote it:

```untrusted-server-text
Lists free tiers, signup credits, trial credits and discounts on AI APIs: inference, GPU, search, embeddings, vector databases, speech and vision, eval and observability, and compute sandboxes. Filters by capability and by provider or offer name. Each row gives limits, offer_status, access (what the first call needs: api-key, credit-card, oauth, web-form, phone-verification, account or none, or null), source_url, verified_at and verified_days_ago. A row with access credit-card needs a payment card to get that offer; a null access is not a sign of card-free access. Rows state what the provider advertised on verified_at, not today.
```

### `get_offer`

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

Description, as the server wrote it:

```untrusted-server-text
Full record for one provider's offer, matched by provider or offer name: limits, caveats, deal_type, offer_status, access (what the first call needs, such as api-key or credit-card; or null, which is not a sign that no card is needed), expires_at, source_url, verified_at and verified_days_ago. offer_status is available, retired, unverified, or none (checked, and no free API path was found). Covers questions such as whether a provider has a free API, whether its free tier is still on as of verified_at, what its free limits are, and whether a card is needed. On no match it returns the nearest candidates rather than an empty result.
```

## Claude Code permissions
