Nexus-MCP

#Nexus-MCP ( Foundry-Reverse )

Newer Foundry MCP reverse-engineered to work on Ollama

---

A fully local, open-source alternative to the Azure AI Foundry MCP Server, powered entirely by Ollama.
No Azure subscription, no API keys, no cloud required.

Features

Category	Tools
Health	health_check
Model Management	list_models, get_model_info, pull_model, delete_model, list_running_models, compare_models
Inference	generate, chat
Evaluation	evaluate_response, evaluate_agent
Knowledge / RAG	create_index, list_indexes, add_document, query_knowledge, delete_index

Plus MCP Resources (ollama://models, ollama://running, ollama://indexes) and reusable Prompts (summarize, rag_answer, code_review).

Requirements

• Python 3.12+
• Ollama running locally (ollama serve)
• uv (recommended) or pip

Quick Start

# 1. Clone
git clone https://github.com/deadSwank001/Foundry-Reverse.git
cd Foundry-Reverse

# 2. Copy and edit configuration
cp .env.example .env

# 3. Run the MCP server (stdio transport)
uv run foundry-reverse

VS Code / Copilot Integration

Copy mcp.json to your VS Code workspace .vscode/mcp.json (or user-level MCP config), then restart VS Code.
