## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `catalog-url`

- 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
FREE helper: returns the public Rainmaker catalog.json URL (same data as list-wells, hosted on rainmaker-catalog).
```

### `recommend-well`

- 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
Keyword-route a natural-language need to the best Rainmaker well ($0.005 USDC via x402). Returns well id, origin, tool, price_usd, mcp URL, and why. After recommend, open that origin's /mcp directly — gateway does not proxy (avoids double-charge). Free alternative: list-wells. Provided as is, with no warranty or guarantee of accuracy or fitness. Nothing is stored.
```

## Only reads (1)

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

### `list-wells`

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

Description, as the server wrote it:

```untrusted-server-text
FREE catalog of Rainmaker wells (001–012, 015, 016): id, name, tool, origin, price_usd, description, mcp_path. Also returns catalog_url. After picking a well, open {origin}/mcp directly.
```

## Claude Code permissions
