• Comprehensive Data Access:
  • Catalytic reactions (equations, conditions, catalysts)
  • Material systems (structures, properties, descriptors)
  • Research publications (titles, DOIs, authors)
  • Surface reaction data (adsorption energies, binding sites)
• MCP Standard Compliance: Implements the Model Context Protocol for AI-agent interoperability
• Flexible Query Support: Execute complex queries with variables parameterization
• Error Handling: Robust error reporting for API connectivity and query execution
