About EPA Computational Toxicology MCP Server
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.
Pydantic AI validates every EPA Computational Toxicology tool response against typed schemas, catching data inconsistencies at build time. Connect 10 tools through the Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code — full type safety, structured output guarantees, and dependency injection for testable agents.
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
The EPA Computational Toxicology MCP Server exposes 10 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
