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 Cursor?
Cursor's Agent mode turns EPA Computational Toxicology into an in-editor superpower. Ask Cursor to generate code using live data from EPA Computational Toxicology and it fetches, processes, and writes. all in a single agentic loop. 10 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

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.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
