Data Science & ML MCP Servers
Compare the best open-source MCP servers for data science & ML. Models, RAG pipelines, embeddings and datasets. Ranked by GitHub stars, with install commands, what each one can touch and scan reports where available.
Knowledge Rag
Local RAG MCP server for Claude Code — hybrid search (semantic + BM25), cross-encoder reranking, 13 MCP tools, 20 format parsers. Zero external servers, zero API keys.
MCP Engine Public
The SemanticOps MCP (formerly MCP Engine) is a Power BI tool that lets AI assistants like Claude interact with your Power BI models programmatically: read your model structure, run DAX queries, modify your semantic model, and perform advanced analytics - all through natural conversation.
PharosRAG
Pharos — local-first agentic RAG for your team's document library: multi-format ingest, hybrid retrieval, enterprise ACL, dual HTTP + MCP exits.
AgentCrew
Chat application with multi-agents system supports multi-models and MCP
Chiasmus
Chiasmus is an MCP server that gives language models access to formal verification
MakerAi
The AI Operating System for Delphi. 100% native framework with RAG 2.0, autonomous agents, MCP protocol, and universal LLM connector. Supports OpenAI, Claude, Gemini, Ollama, and more. Delphi 10.4+ (limited), full support from Delphi 12 Athens.
