Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

hazcom

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.

safety

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.

How do I connect SDSentry — SDS Lookup & OSHA HazCom?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

No. SDSentry — SDS Lookup & OSHA HazCom completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is SDSentry — SDS Lookup & OSHA HazCom?

It answers our handshake in 656 ms on average, which is faster than 21% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
