MSDS Chain MCP Server

Chemical safety intelligence for AI-assisted experiment design.

An MCP server that gives AI agents (Claude Code, Cursor, Copilot, pi, etc.) access to chemical safety reasoning — compatibility checks, hazard analysis, regulatory compliance, PPE recommendations, storage guidance, and more.

Built for researchers who design experiments with AI and need safety verification integrated into their workflow.

Why This Exists

When you use Claude to plan a synthesis route or set up an Opentrons protocol, safety validation shouldn't be a separate step. This MCP server lets your AI assistant automatically:

Check if chemicals on the same deck are compatible
Flag dangerous mixing orders
Recommend PPE for the specific chemicals you're handling
Verify compliance with EU REACH, US OSHA/TSCA, and 7 other jurisdictions
Generate signed audit reports for GLP/GMP compliance
