How to Use the EPA Computational Toxicology MCP in VS Code Copilot

Q: How do I share the EPA Computational Toxicology configuration with my team in VS Code Copilot?

Create a .vscode/mcp.json file in your project root, define the server details, and commit it to your Git repository. Once your team pulls the latest changes, VS Code Copilot automatically loads the ten tools using your global MCP settings.

Q: Can VS Code Copilot use EPA Computational Toxicology to write data schemas?

Yes, Copilot can call getchemicaldetails to inspect the exact JSON payload returned by the EPA. It then writes accurate TypeScript interfaces or database schemas based on the real-world structure of the CompTox data.

Q: How does EPA Computational Toxicology help with regulatory compliance in VS Code Copilot?

Your agent can call gethazardsummary to check a list of chemicals against ToxValDB toxicity values. Copilot can then write scripts to automatically flag any compounds in your database that exceed regulatory safety thresholds.

Give VS Code Copilot direct access to EPA toxicological databases to build, test, and run safety-compliant chemistry pipelines.

Equip your engineering team with this MCP Server

The `get_chemical_lists` tool integrates directly into your VS Code Copilot environment to keep your team aligned on regulatory compliance. By committing a `.vscode/mcp.json` file to your repository, every developer on the team instantly gains access to the same EPA tools. Your agent can check chemical lists to flag restricted substances during code reviews. This shared configuration eliminates manual setup headaches and ensures everyone uses the same data sources. Copilot references live EPA lists to validate your database migrations and compliance scripts. You build a consistent, team-wide workflow for environmental data engineering.

Accelerate chemical database lookups in VS Code Copilot

The `search_chemical_by_casrn` tool lets your VS Code Copilot agent find chemical records using standard CAS Registry Numbers directly from the chat panel. You don't need to open a browser or switch to an external database client to verify an identifier. This lookup retrieves the correct DTXSID and inserts it directly into your active file. If you only have a common name, the agent uses `search_chemical_by_name` to resolve spelling variations and IUPAC names. Copilot writes the data ingestion code using verified identifiers from the EPA CompTox database. It keeps your database clean and prevents duplicate records from entering your pipeline.

Fetch bioactivity and fate data during code reviews

The `get_bioactivity_summary` tool retrieves ToxCast high-throughput screening data directly into your VS Code Copilot workspace. When reviewing data pipelines, you can ask Copilot to explain the bioactivity profile of a target compound. This process fetches the active assays and explains the biological targets in plain English. To evaluate environmental persistence, the agent calls `get_fate_and_transport` to pull bioconcentration and half-life data. Copilot uses this environmental fate context to help you write accurate data validation rules. You catch potential environmental compliance issues before your code ever hits production.

Setup guide

Set up EPA Computational Toxicology MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the EPA Computational Toxicology MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the EPA Computational Toxicology tools listed. Try asking: "List my recent EPA Computational Toxicology transactions" and Copilot will invoke them automatically.
