```

## Only reads (1)

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

### `calculator_describe`

- The name "calculator_describe" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The inputs this calculator takes (with units, ranges and defaults), the outputs it returns, and the assumptions and tables behind it.
```
