## Findings

No check matched anything in these tool definitions.


## Only reads (3)

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

### `check_hazcom_readiness`

- The description's first verb is "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Explains the OSHA Hazard Communication (HazCom) employer compliance deadline and what a facility that stores chemicals needs in place (current safety data sheets, GHS container labels, a written program, and documented employee training), then points to a free, no-signup readiness self-audit. Does NOT invent fines, statistics, or legal conclusions. Use it when someone asks whether their business is OSHA HazCom compliant or ready for the deadline.
```

### `find_safety_data_sheet`

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

Description, as the server wrote it:

```untrusted-server-text
Look up the manufacturer safety data sheet (SDS/MSDS) for a workplace chemical or product by name. Returns the product name, manufacturer, CAS number(s), EPA registration where applicable, a link to the actual SDS PDF, and a confidence level. If the product cannot be identified reliably it says so plainly rather than guessing — a wrong SDS is worse than none. Free, no signup. Use it when someone needs hazard or handling information, or the SDS, for a chemical they keep on site.
```

### `find_sds_for_inventory`

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

Description, as the server wrote it:

```untrusted-server-text
Look up the manufacturer safety data sheet (SDS) for a LIST of workplace chemicals or products at once, e.g. the product-name column of a chemical inventory spreadsheet. Returns one row per product: whether a verified SDS PDF was found, the manufacturer, and the PDF link, using the same rules as find_safety_data_sheet (an unidentifiable product is reported as not found, never guessed). Up to 10 products per call; call again for the rest. Free, no signup. Use it when someone has several chemicals or an SDS binder/inventory to fill in.
```
