This server provides a reliable way to access and query ontologies, ensuring accurate and up-to-date information. This repository contains a Model Context Protocol (MCP) server providing access to the Ontology Lookup Service (OLS) API. This server enables AI assistants to search for and retrieve ontological terms, concepts, and hierarchies from various biological and medical ontologies. This server is designed to work seamlessly with AI assistants like Claude Desktop, allowing users to query ontologies using natural language. It supports a wide range of ontologies, including Gene Ontology (GO), Human Phenotype Ontology (HP), and many others. Without (top part of image below) and with mcp server engaged (bottom of figure below): Features The OLS MCP Server provides the following tools: - 🔍 Search Terms : Search for terms across ontologies with flexible filtering - 📚 Search Ontologies : Discover available ontologies and their metadata - ℹ️ Get Ontology Information : Retrieve detailed information about specific ontologies - 🎯 Get Term Information : Get comprehensive details about specific terms - 🌳 Get Term Children : Find direct child terms in ontological hierarchies - 👨‍👩‍👧‍👦 Get Term Ancestors : Retrieve parent terms and ancestors - 🤖 Find Similar Terms : Discover semantically similar terms using LLM embeddings Supported Ontologies The ","default_branch":null,"files":null,"tree":[],"storefront":"/r/seandavi","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/seandavi/ols-mcp-server/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
