Add MSDS Chain — Chemical Safety Intelligence MCP Server

[littleblakew]

Summary

Adding MSDS Chain as the first chemical safety MCP server in the Life Sciences marketplace.

• 18 tools for chemical safety reasoning — compatibility checks, GHS hazard analysis, PPE recommendations, storage guidance, waste disposal, mixing order safety, occupational exposure limits, transport classification, multi-region regulatory compliance (8 jurisdictions), safer alternatives, protocol text parsing, SDS section lookup, batch safety audit, and signed PDF reports
• Remote MCP at https://mcp.lagentbot.com/mcp (streamable-http)
• 5 languages (EN/ZH/JA/DE/ID), 4,200+ chemicals with multi-language aliases
• Free tier: 100 calls/month with API key (sign up at https://msdschain.lagentbot.com)

Why it belongs here

Researchers using Claude to design experiments need safety verification integrated into their workflow. The marketplace has tools for literature (PubMed), compounds (ChEMBL), genomics (10x), but no chemical safety reasoning. MSDS Chain fills this gap — it doesn't just extract SDS documents, it provides safety reasoning (compatibility judgments, risk analysis, compliance advice).

Target users

• Lab researchers designing experiments with hazardous chemicals
• EHS (Environment, Health & Safety) officers
• Pharmaceutical R&D teams
• Lab automation engineers (Opentrons/Hamilton/Tecan)
