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.
Mastra's agent abstraction provides a clean separation between LLM logic and EPA Computational Toxicology tool infrastructure. Connect 10 tools through the Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution — deployable to any Node.js host in one command.
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 Mastra AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
