#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.
