Solr MCP

A Python package for accessing Apache Solr indexes via Model Context Protocol (MCP). This integration allows AI assistants like Claude to perform powerful search queries against your Solr indexes, combining both keyword and vector search capabilities.

Features

• MCP Server: Implements the Model Context Protocol for integration with AI assistants

• Hybrid Search: Combines keyword search precision with vector search semantic understanding

• Vector Embeddings: Generates embeddings for documents using Ollama with nomic-embed-text

• Unified Collections: Store both document content and vector embeddings in the same collection

• Docker Integration: Easy setup with Docker and docker-compose
