🔬 MCP server to query KumoRFM in your agentic flows

</div>

📖 Introduction

KumoRFM is a pre-trained Relational Foundation Model (RFM) that generates training-free predictions on any relational multi-table data by interpreting the data as a (temporal) heterogeneous graph. It can be queried via the Predictive Query Language (PQL).

This repository hosts a full-featured MCP (Model Context Protocol) server that empowers AI assistants with KumoRFM intelligence. This server enables:

• 🕸️ Build, manage, and visualize graphs directly from CSV or Parquet files
• 💬 Convert natural language into PQL queries for seamless interaction
• 🤖 Query, analyze, and evaluate predictions from KumoRFM (missing value imputation, temporal forecasting, etc) all without any training required

🚀 Installation

🐍 Traditional MCP Server

The KumoRFM MCP server is available for Python 3.10 and above. To install, simply run:

pip install kumo-rfm-mcp

Add to your MCP configuration file (e.g., Claude Desktop's mcp_config.json):

{
  "mcpServers": {
    "kumo-rfm": {
      "command": "python",
      "args": ["-m", "kumo_rfm_mcp.server"],
      "env": {
        "KUMO_API_KEY": "your_api_key_here"
      }
    }
  }
}

HTTP Transport

For HTTP-native MCP clients such as a Snowflake Native App, run the server with streamable-http instead of stdio:

KUMO_API_KEY=<YOUR-KUMO-API-KEY> \
MCP_BEARER_TOKEN=<SHARED-MCP-TOKEN> \
python -m kumo_rfm_mcp.server \
  --transport streamable-http \
  --host 0.0.0.0 \
  --port 8000 \
  --path /mcp

Notes:

• Set KUMO_API_KEY up front for headless deployments. This avoids the browser-based OAuth flow.
• If your MCP client cannot inject environment variables, call the authenticate tool with an api_key argument once at session start.
• If MCP_BEARER_TOKEN is set, the HTTP endpoint requires Authorization: Bearer <SHARED-MCP-TOKEN>.

⚡ MCP Bundle

We provide a single-click installation via our MCP Bundle (MCPB) (e.g., for integration into Claude Desktop):

1. Download the dxt file from here
2. Double click to install

The MCP Bundle supports Linux, macOS and Windows, but requires a Python executable to be found in order to create a separate new virtual environment.

Claude code

To include the server in claude code use:

claude mcp add --transport stdio kumo-rfm-mcp --env KUMO_API_KEY=<YOUR-API-KEY> -- python -m kumo_rfm_mcp.server --port 8000
