🔬 MCP server to query KumoRFM in your agentic flows

📖 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

📚 Available Tools

I/O Operations

• 🔍 find_table_files - Searching for tabular files: Find all table-like files (e.g., CSV, Parquet) in a directory.

• 🧐 inspect_table_files - Analyzing table structure: Inspect the first rows of table-like files.

Graph Management

• 🗂️ inspect_graph_metadata - Reviewing graph schema: Inspect the current graph metadata.

• 🔄 update_graph_metadata - Updating graph schema: Partially update the current graph metadata.

• 🖼️ get_mermaid - Creating graph diagram: Return the graph as a Mermaid entity relationship diagram.

• 🕸️ materialize_graph - Assembling graph: Materialize the graph based on the current state of the graph metadata to make it available for inference operations.

• 📂 lookup_table_rows - Retrieving table entries: Lookup rows in the raw data frame of a table for a list of primary keys.

Model Execution

• 🤖 predict - Running predictive query: Execute a predictive query and return model predictions.

• 📊 evaluate - Evaluating predictive query: Evaluate a predictive query and return performance metrics which compares predictions against known ground-truth labels from historical examples.

• 🧠 explain - Explaining prediction: Execute a predictive query and explain the model prediction.

🔧 Configuration

Environment Variables

• KUMO_API_KEY: Authentication is needed once before predicting or evaluating with the KumoRFM model. You can generate your KumoRFM API key for free here. If not set, you can also authenticate on-the-fly in individual session via an OAuth2 flow.
