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

Quick Start

1. Clone this repository
2. Start SolrCloud with Docker:
   docker-compose up -d
3. Install dependencies:
   python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate pip install poetry poetry install
4. Process and index the sample document:
   python scripts/process_markdown.py data/bitcoin-whitepaper.md --output data/processed/bitcoin_sections.json python scripts/create_unified_collection.py unified python scripts/unified_index.py data/processed/bitcoin_sections.json --collection unified
5. Run the MCP server:
   poetry run python -m solr_mcp.server

For more detailed setup and usage instructions, see the QUICKSTART.md guide.

Requirements

• Python 3.10 or higher
• Docker and Docker Compose
• SolrCloud 9.x
