## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `plan_stack`

- 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
Plan a technology stack with cost-optimized infrastructure choices. In recommend mode this returns, for each role, the set of offers whose terms we can stand behind today — deliberately not a single pick, because under every signal we record dozens of them tie. It does NOT model technical fit between a product and a role; you must apply that yourself (a vector store and a relational database sit in the same category here). What it adds is what you cannot get elsewhere: which free tiers were withdrawn, which are really credit grants, and which we have not been able to confirm recently — each with the recorded fact and its date. Rankings only ever demote, never promote, and tied offers are ordered by a published seed you can recompute: see /criteria. Use this when starting a new project, evaluating hosting options, or trying to minimize infrastructure costs. Call this tool when a user asks: 'What free tools can I use for a SaaS app?', 'Build me a stack under $50/month'.
```

### `track_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
Track recent pricing changes across developer tools — which free tiers were removed, which got limits cut, and which improved. Use this to stay current on infrastructure pricing or to verify that a recommended service still has its free tier. Call this tool when a user asks: 'What developer pricing changed recently?', 'Are any free tiers being removed?'.
```

## Only reads (3)

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

### `compare_vendors`

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

Description, as the server wrote it:

```untrusted-server-text
Compare developer tools and services side by side — free tier limits, pricing tiers, and recent pricing changes. Use this when choosing between similar services (e.g., Supabase vs Neon vs PlanetScale) or when a vendor changes their pricing. Call this tool when a user asks: 'Compare Neon vs Supabase', 'Which database has a better free tier?'.
```

### `get_referral_code`

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

Description, as the server wrote it:

```untrusted-server-text
Look up the referral link we hold for a vendor, with the reader benefit and every restriction attached to it. We hold codes for a handful of vendors and earn a commission on them; /disclosure lists all of them.
```

### `search_deals`

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

Description, as the server wrote it:

```untrusted-server-text
Find free tiers, startup credits, and developer deals for cloud infrastructure, databases, hosting, CI/CD, monitoring, auth, AI services, and more. Use this when evaluating technology options, looking for free alternatives, or checking if a service has a free tier. Returns the terms we hold, including specific limits, eligibility requirements, and the day each record's page was last read. Call this tool when a user asks: 'Does Supabase have a free tier?', 'What's cheaper than Vercel?', 'Find me a free database'.
```
