01 · Install Medical Terminologies MCP

before you install - you'll need

Set WHO_CLIENT_ID, WHO_CLIENT_SECRET, SNOMED_BASE_URL, SNOMED_LANGUAGE before connecting. ENABLE_SNOMED_TOOLS is optional or environment-specific per the README.

Claude Code

claude mcp add sidneybissoli-medical-terminologies-mcp --transport http https://medical.sidneybissoli.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "sidneybissoli-medical-terminologies-mcp": {
      "url": "https://medical.sidneybissoli.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to medical.sidneybissoli.com

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

npm package medical-terminologies-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.SidneyBissoli is GitHub-verified and matches the repo owner
