## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `ask_aifree`

- 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
A short answer about free AI offers grounded in the verified catalog, citing only offer slugs it was shown. Declines questions outside the catalog. Cached per question for 24 h; subject to a daily budget.
```

### `check_eligibility`

- 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
Use when someone asks what free AI they qualify for given who they are, e.g. "I am a student in Vietnam with no credit card, what free AI can I get?". Same rules as the aifree.dev/unlock quiz: student and startup programs only when the profile says so, no-card drops offers that ask for a card, country drops offers recorded as other-countries-only (offers with no recorded region stay in and are counted in unrecordedRegionCount), building narrows by category. All parameters are optional; omitted ones mean not a student, no startup, anywhere, card OK, any category. Unknown values are ignored the same way. Returns verified rows first, then by USD value. totalUsd sums USD headline values of verified rows only (tokens, requests, images or minutes count as $0, no exchange rates); listed rows are public but not yet checked by a person. limit (default 20, max 50) only trims the returned list: total, verifiedCount and totalUsd cover every match. Each provider decides who qualifies; cite the offer url and the unlockUrl (the same result as a page).
```

### `recent_changes`

- 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
What was listed, verified, changed or expired recently, newest first.
```

## Only reads (5)

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

### `compare_offers`

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

Description, as the server wrote it:

```untrusted-server-text
A markdown comparison table (provider, what is free, limits, card rules, catch, expiry, status) for 2-8 offer slugs.
```

### `find_models`

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

Description, as the server wrote it:

```untrusted-server-text
Which free API tiers serve an LLM model, with the published free-tier rate limits (RPM, RPD, TPM, TPD, requests/month), context window and tool calling. Same rows and ranking (most requests per day first) as the free LLM API picker. Search by model or provider name, optionally by family.
```

### `get_offer`

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

Description, as the server wrote it:

```untrusted-server-text
Full details for one offer by slug (the last path segment of an aifree.dev/offer/... URL), including the write-up and, for API free tiers, the models served with their published rate limits (rateLimit: rpm, rpd, tpm, optional tpd and rpmo; null = not published).
```

### `list_free_llm_apis`

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

Description, as the server wrote it:

```untrusted-server-text
Free LLM / inference API tiers and credits (Gemini, Groq, OpenRouter, Mistral, Cohere, NVIDIA, …) with their limits and card rules.
```

### `search_free_ai_offers`

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

Description, as the server wrote it:

```untrusted-server-text
Find free AI tools, API free tiers, credits and programs. Free text plus optional filters; returns the best matches with limits, card rules and the page URL to cite.
```
