Omophub MCP

Medical vocabularies for AI agents. Search, map, and navigate 11M+ OMOP concepts: SNOMED CT, ICD-10, RxNorm, LOINC, and more. Directly from Claude, Cursor, VS Code, or any MCP-compatible client. Its 11 documented tools cover concept, concepts, fhir, resolve. It runs locally over stdio via the published package.

People who work with concept, concepts and fhir and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Omophub MCP

before you install - you'll need

Set OMOPHUB_API_KEY before connecting. HEALTH_PORT is optional or environment-specific per the README.

Claude Code

claude mcp add omophub-omophub-mcp -- npx -y @omophub/omophub-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "omophub-omophub-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@omophub/omophub-mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

02 · Evidence

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

license MIT - declared in the repository

npm package @omophub/omophub-mcp - published under the repo owner's npm scope (@omophub)

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

03 · What Omophub MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can search for medical concepts by name or clinical term across all vocabularies, get detailed info about a specific OMOP concept by concept_id, map a concept to equivalent concepts in other vocabularies (paginated - see note below), and navigate concept hierarchy - ancestors, descendants, or both.

Tools grouped from the project's README - what Omophub MCP lets an agent do.

Concept

5 tools - e.g. Get detailed info about a specific OMOP concept by concept_id; Look up a concept using a vocabulary-specific code (e.g., ICD-10 E11.9); Map a concept to equivalent concepts in other vocabularies…

Semantic

1 tool - e.g. Search using natural language with neural embeddings (understands clinical meaning)

Fhir

1 tool - e.g. Resolve a FHIR coded value (incl. administrative codes via the HL7 FHIR-to-OMOP IG ConceptMaps) to its OMOP standard concept and CDM target table

What can Omophub MCP do?

With this server connected, an agent can search for medical concepts by name or clinical term across all vocabularies, get detailed info about a specific OMOP concept by concept_id, map a concept to equivalent concepts in other vocabularies (paginated - see note below), and navigate concept hierarchy - ancestors, descendants, or both.

How do I install Omophub MCP?

Run `npx -y @omophub/omophub-mcp`. The README documents 2 environment variables (OMOPHUB_API_KEY, HEALTH_PORT) to set first. Set OMOPHUB_API_KEY before connecting. HEALTH_PORT is optional or environment-specific per the README. You can also paste the ready-made client config above.

Does Omophub MCP run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
