Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.
Set these up before or after installing:
Environment variable: MSDS_API_KEY
Add this to your MCP configuration file:
{
"mcpServers": {
"io-github-littleblakew-msds-chain": {
"env": {
"MSDS_API_KEY": "your-msds-api-key-here"

Chemical safety intelligence for AI-assisted experiment design.
An MCP server that gives AI agents (Claude Code, Cursor, Copilot, 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.
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:
| Tool | Description |
|---|---|
batch_safety_check | One-call comprehensive report: compatibility + PPE + storage grouping for a chemical list |
get_sds_section | Retrieve a specific SDS section (1-16) for a chemical |
get_chemical_alternatives | Safer substitutes for restricted or high-risk chemicals |
validate_protocol_chemicals | Extract & validate chemical names from protocol text or code |
check_mixing_order | Safe addition sequence for reagent pairs (e.g., acid into water) |
get_waste_disposal | Waste classification, container type, and disposal procedures |
check_chemical_compatibility | Pairwise compatibility for 2+ chemicals |
get_chemical_risk_warnings | GHS classification, H-codes, signal words, flash point |
get_ppe_recommendation | Gloves, eye protection, respiratory, body protection |
get_storage_guidance | Storage class, cabinet type, temperature, isolation rules |
get_emergency_response | Spill, fire, or exposure emergency procedures |
get_exposure_limits | OEL/TLV/PEL/MAC across US, EU, JP, CN, INT |
get_transport_classification | UN number, hazard class, packing group, ADR/IATA/IMDG |
check_regulatory_compliance | Multi-region: EU, US, CN, JP, KR, CA, AU, TW |
search_chemical_database | Look up chemicals by name, synonym, or CAS number |
ask_chemical_safety | Natural language catch-all for any safety question |
create_audit_session | Full audit with signed PDF report (requires API key) |
get_audit_report | Download link for the signed audit PDF |

git clone https://github.com/littleblakew/msds-chain-mcp.git
cd msds-chain-mcp
pip install -r requirements.txt
Claude Code:
claude mcp add msds-chain -- python /path/to/msds-chain-mcp/server.py
OpenAI Codex:
codex marketplace add https://github.com/littleblakew/msds-chain-mcp
Manual config (Claude Code ~/.claude.json or Codex .agents/):
{
"mcpServers": {
"msds-chain": {
"command": "python",
"args": ["/absolute/path/to/msds-chain-mcp/server.py"],

Restart Claude Code. You should see msds-chain in the MCP tools list.
User: I'm planning a Grignard reaction with magnesium turnings, diethyl ether,
and bromobenzene. Check if this setup is safe.
Claude:
→ calls batch_safety_check(["magnesium", "diethyl ether", "bromobenzene"])
→ Returns: compatibility matrix, PPE requirements, storage grouping
User: My Opentrons deck has these in different slots:
Slot 1: Acetone, Slot 3: Concentrated H2SO4, Slot 5: Methanol,
Slot 7: Sodium borohydride. Any safety issues?
Claude:
→ calls check_chemical_compatibility(["acetone", "sulfuric acid", "methanol", "sodium borohydride"])
→ ⚠️ INCOMPATIBLE: Sodium borohydride + sulfuric acid (violent reaction, H2 gas evolution)
→ ⚠️ CAUTION: Acetone + sulfuric acid (exothermic)
→ Recommendation: Move sodium borohydride to maximum distance from acids
User: We need to ship toluene and dichloromethane to our Japan lab.
What transport regulations apply?
Claude:
→ calls get_transport_classification(["toluene", "dichloromethane"])
→ calls check_regulatory_compliance(["toluene", "dichloromethane"], regions=["JP"])
→ Returns: UN numbers, IATA packing instructions, Japan-specific regulations
User: Create a safety audit report for our quarterly review.
Chemicals: acetone, methanol, ethanol, isopropanol, hexane.
Claude:
→ calls create_audit_session("Q2 2026 Solvent Cabinet Review", ["acetone", "methanol", "ethanol", "isopropanol", "hexane"])
→ calls get_audit_report("SESSION-ID")
→ Returns: Signed PDF URL (Ed25519 signature, suitable for GLP/GMP compliance)
