VS Code

Configure Clinical Terminology MCP servers in VS Code with GitHub Copilot.

VS Code supports MCP servers through GitHub Copilot’s chat feature. Servers are configured in your VS Code settings.json under the github.copilot.chat.mcp.servers key.

Config File Location

OS	Path
macOS	`~/Library/Application Support/Code/User/settings.json`
Linux	`~/.config/Code/User/settings.json`
Windows	`%APPDATA%\Code\User\settings.json`

You can also open it from VS Code: Cmd+Shift+P (macOS) or Ctrl+Shift+P (Windows/Linux) and search for “Preferences: Open User Settings (JSON)”.

Basic Setup

Add a single server to your settings.json:

{
  "github.copilot.chat.mcp.servers": {
    "snomed": {
      "command": "/usr/local/bin/snomed-mcp"
    }
  }
}

Complete Configuration

All seven servers:

{
  "github.copilot.chat.mcp.servers": {
    "snomed": {
      "command": "/usr/local/bin/snomed-mcp",
      "env": {
        "SNOWSTORM_BRANCH": "MAIN/SNOMEDCT-US"
      }
    },
    "rxnorm": {
      "command": "/usr/local/bin/rxnorm-mcp"
    },
    "icd10": {
      "command": "/usr/local/bin/icd10-mcp"
    },
    "icd11": {
      "command": "/usr/local/bin/icd11-mcp",
      "env": {
        "ICD11_CLIENT_ID": "your-client-id",
        "ICD11_CLIENT_SECRET": "your-client-secret"
      }
    },
    "loinc": {
      "command": "/usr/local/bin/loinc-mcp",
      "env": {
        "LOINC_USERNAME": "your-username",
        "LOINC_PASSWORD": "your-password"
      }
    },
    "umls": {
      "command": "/usr/local/bin/umls-mcp",
      "env": {
        "UMLS_API_KEY": "your-api-key"
      }
    },
    "ucum": {
      "command": "/usr/local/bin/ucum-mcp"
    }
  }
}

Servers Requiring Credentials

Three servers need credentials configured via environment variables or system keyring:

Server	Environment Variables
ICD-11	`ICD11_CLIENT_ID`, `ICD11_CLIENT_SECRET`
LOINC	`LOINC_USERNAME`, `LOINC_PASSWORD`
UMLS	`UMLS_API_KEY`

Start with servers that don’t require authentication (snomed, rxnorm, icd10, ucum) and add authenticated services as needed.

Remote / HTTP Setup

Connect to a remote server running in HTTP mode:

{
  "github.copilot.chat.mcp.servers": {
    "snomed": {
      "url": "https://your-server.com/mcp",
      "type": "http"
    }
  }
}

See HTTP Transport for server-side setup and Remote Deployment for deployment guides.
