EPA Computational Toxicology

EPA Computational Toxicology MCP Connector for Claude

A+

Access the US EPA's CompTox Chemicals Dashboard data — search for chemicals, properties, hazard summaries, and exposure data.

10 tools Official Updated Jun 28, 2026 Official Vinkius Partner

Connect to the US Environmental Protection Agency's (EPA) Center for Computational Toxicology and Exposure (CCTE) and explore a massive repository of chemical data through natural conversation.

What you can do

  • Chemical Search — Find substances by name, CAS Registry Number (CASRN), or DTXSID
  • Physicochemical Properties — Retrieve melting points, boiling points, logP, and water solubility
  • Hazard Assessments — Access toxicity values, NOAELs, and points-of-departure from ToxValDB
  • Exposure Predictions — Explore predicted exposure levels and product use categories via ExpoCast and CPDat
  • Bioactivity Screening — Analyze ToxCast/Tox21 high-throughput screening results for thousands of assays
  • Environmental Fate — Check persistence, transport, and biodegradation metrics
