Overview
What is LOINC API MCP Server?
A modular Python wrapper for the LOINC API that provides an MCP server interface for use with Claude Desktop. It enables intelligent medical terminology lookup and standardization, allowing users to search for LOINC codes, retrieve detailed code information, access panels, navigate hierarchies, and work with standardized answer lists.
How to use LOINC API MCP Server?
Install dependencies with pip install -r requirements.txt, then start the server with python loinc_server.py --username=your_loinc_username --password=your_loinc_password. For Claude Desktop integration, add the MCP server configuration (name, URL, basic auth credentials) to your Claude Desktop config file. The server provides MCP tools that accept JSON parameters for searching, fetching details, and navigating LOINC data.

What if I get empty results from a search?
Ensure your LOINC account has the proper permissions and that you are using the correct authentication credentials.
Can I use the server without an internet connection?
Yes. Create a local LOINC database by running python loinc_server.py --create-db --username=... --password=.... Then the server can operate offline against that database.
What are the main MCP tools available?
The server provides tools for LOINC code search, LOINC details retrieval, panel information, hierarchy navigation, and access to top 2000 codes and answer lists.
