## Quality 96/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 663 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 1 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 663 tokens to load them all
- tool set hash: a5b2fcf2a369261db4e1359c09fd0190
- tools last changed: 2026-10-10T00:11:35.510Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.0xpi.sdsentry/sds-lookup.svg)](https://protogrid.dev/servers/com.0xpi.sdsentry/sds-lookup)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-10 `find_sds_for_inventory` added
  - 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.

## Tools (3)

- `check_hazcom_readiness`: 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`: 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`: 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.
