How to Build Element Datasets with OpenClaw
Build complete element property datasets with OpenClaw and ToolRouter.
Tool
OpenClaw processes element data requests for the entire periodic table or any subset in a single batch run, making it ideal for building chemistry reference databases, materials science datasets, and educational platforms that need comprehensive, up-to-date element data.
Connect ToolRouter to OpenClaw
1Install the CLI
npm install -g toolrouter-mcp2Call tools directly from OpenClaw
toolrouter-mcp call web-search search --query "AI tools"
toolrouter-mcp toolsSteps
Once connected (see setup above), use the Chemistry Lookup tool:
- Run: "Get properties for all transition metals using chemistry-lookup"
- OpenClaw returns a complete dataset for all transition metal elements
- Load into your chemistry platform or research database
- Refresh annually to capture any updated standard atomic weights
Example Prompt
Try this with OpenClaw using the Chemistry Lookup tool
Get element properties for all 118 elements using chemistry-lookup. Return as a JSON array sorted by atomic number with symbol, name, atomic weight, group, and period.
Tips
- Pull the full periodic table once and cache it — element properties are effectively immutable
- Structure the dataset by group and period for efficient filtering in chemistry apps
- Include electron configuration in the batch pull to enable orbital-based filtering
