KGrag MCP Server

KGrag MCP Server is a server that implements the Model Context Protocol (MCP) for managing, ingesting, and querying structured and unstructured data. It is designed for easy integration with graph databases (Neo4j), AWS S3 storage, Redis cache, vector search engines (Qdrant), and advanced language models (LLM).
The project provides a scalable, containerized infrastructure via Docker Compose to orchestrate data pipelines, semantic enrichment, and analysis through advanced queries.
Ideal for knowledge graph, AI, and information flow automation applications.

Example: Ingestion and Query with GitHub Copilot in VSCode (Agent Mode)

You can use GitHub Copilot in VSCode to interactively ingest documents into the MCP Server using an agent-based workflow and a configuration file.

Step-by-step:

1. Open VSCode and ensure GitHub Copilot is enabled.
2. Create an mcp.json configuration file in your project directory:

{
	"servers": {
		"kgrag-server": {
			"url": "http://localhost:8000/sse",
			"type": "sse"
		}
	},
	"inputs": []
}

3. Let Copilot suggest ingestion code and improvements such as error handling or batch processing, using the configuration from mcp.json.

This workflow enables rapid prototyping and automation of ingestion tasks with Copilot's agent capabilities and a configurable server endpoint.
