What is the 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.
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
How it works
- Subscribe to this server
- Enter your free EPA API Key (request it by emailing
ccte_api@epa.gov) - Start investigating chemical safety and properties directly from your agent
This tool is essential for toxicologists, environmental scientists, and regulatory professionals who need instant access to high-quality chemical data.
Who is this for?
- Toxicologists — quickly gather hazard and bioactivity data for risk assessments
- Environmental Scientists — analyze fate and transport properties of contaminants
- Product Safety Teams — check chemical exposure and product use profiles
- Researchers — retrieve identifiers and synonyms for chemical lists
Built-in capabilities (10)

Frequently asked questions
How do I obtain a free API key for the EPA CTX services?
You must send an email to ccte_api@epa.gov to request an individual API key. The key is usually issued free of charge for research and professional use.
What is a DTXSID and how is it used?
DTXSID is the EPA Dashboard Chemical Identifier. It is the primary unique identifier used across all CompTox APIs to ensure precise substance identification.
Are the results returned in real-time from the EPA databases?
Yes, this agent queries the live CompTox Chemicals Dashboard APIs directly, ensuring you have the most up-to-date scientific data available from the CCTE.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query EPA Computational Toxicology tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
