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)
Retrieve a summary of high-throughput screening results from ToxCast/Tox21 assays
Get comprehensive metadata and identification details for a specific chemical using its DTXSID
Identify which chemical lists (regulatory, research, or commercial) this chemical belongs to
Retrieve all known synonyms and alternative names for a specific chemical
Retrieve predicted exposure levels and product use data (ExpoCast/CPDat)
Retrieve environmental fate and transport data (e.g., half-life, bioconcentration)
Retrieve a summary of toxicity values and hazard assessment data from ToxValDB
Retrieve predicted and experimental physicochemical properties (e.g., melting point, logP, solubility) for a chemical
Search for chemicals by their CAS Registry Number (CASRN)
Search for chemicals by common, IUPAC, or synonym names in the EPA CompTox database
Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 10 tools from EPA Computational Toxicology through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries EPA Computational Toxicology, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

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 the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
