@lagentbot/msds-chain-mcp

Chemical safety intelligence for AI-assisted experiment design. Powered by ChainSDS — verified, current, and growing.

This is a remote MCP (Model Context Protocol) server providing 23 tools for chemical safety reasoning — compatibility checks, hazard analysis, PPE recommendations, storage guidance, waste disposal, mixing order safety, exposure limits, transport classification, regulatory compliance (23 lists, 10 regions), regulatory watch-list cross-reference, SDS version diff, PDF upload, signed SDS document download, chemical substitution, first aid, GHS labels, signed audit reports, and online PubChem GHS fallback for chemicals not yet in the database.

Quick Start

Claude Code:

claude mcp add msds-chain --transport http https://mcp.lagentbot.com/mcp

Then run /mcp and authenticate (browser sign-in). The legacy SSE endpoint (--transport sse https://mcp.lagentbot.com/sse) still works for SSE-only clients.

claude.ai (Web): Search "msds-chain" in Settings > Plugins.

Any MCP client (manual config):

{
  "mcpServers": {
    "msds-chain": {
      "type": "http",
      "url": "https://mcp.lagentbot.com/mcp"
    }
  }
}
