  • •10-100x speedup over IHTSDO Snowstorm for importing clinical editions.
  • •Built-in MCP server allows LLMs to query medical ontologies locally.
Weaknesses
  • •Semantic search requires external Ollama instance, adding setup complexity.
  • •Markdown export and diff features are currently untested and incomplete.

Post Description

SNOMED-CT is the predominant medical terminology - essentially a namespace with an ontology bolted onto it. Existing SNOMED-CT tooling tends to focus on Terminology Servers, which are a pain to set up and learn. This toolkit is right on your computer, simple to use, and 6-60x faster than IHTSDO Snowstorm in tests.
