PromptQL MCP Server

Connect Hasura PromptQL to AI assistants like Claude using the Model Context Protocol (MCP).

Overview

This project provides a bridge between Hasura's PromptQL data agent and AI assistants through the Model Context Protocol. With this integration, AI assistants can directly query your enterprise data using natural language, leveraging PromptQL's powerful capabilities for data access, analysis, and visualization.

Features

• 🔍 Natural Language Data Queries - Ask questions about your enterprise data in plain English
• 📊 Table Artifact Support - Get formatted table results from your data queries
• 🔐 Secure Configuration - Safely store and manage your PromptQL API credentials
• 📈 Data Analysis - Get insights and visualizations from your data
• 🛠️ Simple Integration - Works with Claude Desktop and other MCP-compatible clients

Installation

Prerequisites

• Python 3.10 or higher
• A Hasura PromptQL project with API key and DDN URL
• Claude Desktop (for interactive use) or any MCP-compatible client

Install from Source

1. Clone the repository:

git clone https://github.com/hasura/promptql-mcp.git
cd promptql-mcp

2. Set up a virtual environment (recommended):

# Create a virtual environment
python -m venv venv

# Activate the virtual environment
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install the package:

pip install -e .

Quick Start

1. Configure your PromptQL credentials:

python -m promptql_mcp_server setup --api-key YOUR_PROMPTQL_API_KEY --ddn-url YOUR_DDN_URL

2. Test the server:

python -m promptql_mcp_server

3. In a new terminal, try the example client:

python examples/simple_client.py

Using with Claude Desktop

1. Install Claude Desktop
2. Open Claude Desktop and go to Settings > Developer
3. Click "Edit Config" and add the following:

{
  "mcpServers": {
    "promptql": {
      "command": "/full/path/to/python",
      "args": ["-m", "promptql_mcp_server"]
    }
  }
}

Replace /full/path/to/python with the actual path to your Python executable.

If you're using a virtual environment (recommended):

{
  "mcpServers": {
    "promptql": {
      "command": "/path/to/your/project/venv/bin/python",
      "args": ["-m", "promptql_mcp_server"]
    }
  }
}

To find your Python path, run:

which python  # On macOS/Linux
where python  # On Windows

4. Restart Claude Desktop
5. Chat with Claude and use natural language to query your data

Example Prompts for Claude

• "What were our total sales last quarter?"
• "Who are our top five customers by revenue?"
• "Show me the trend of new user signups over the past 6 months"
• "Which products have the highest profit margin?"

Available Tools and Prompts

Tools

The server exposes the following MCP tools:

• ask_question - Ask natural language questions about your data
• setup_config - Configure PromptQL API key and DDN URL
• check_config - Verify the current configuration status

Prompts

• data_analysis - Create a specialized prompt for data analysis on a specific topic

Architecture

This integration follows a client-server architecture:

1. PromptQL MCP Server - A Python server that exposes PromptQL capabilities through the MCP protocol
2. MCP Client - Any client that implements the MCP protocol (e.g., Claude Desktop)
3. PromptQL API - Hasura's Natural Language API for data access and analysis

The server translates between the MCP protocol and PromptQL's API, allowing seamless integration between AI assistants and your enterprise data.

Troubleshooting

Command not found: pip or python

On many systems, especially macOS, you may need to use python3 and pip3 instead of python and pip.

externally-managed-environment error

Modern Python installations often prevent global package installation. Use a virtual environment as described in the installation section.

No module named promptql_mcp_server

Ensure you've:

1. Installed the package with pip install -e .
2. Are using the correct Python environment (if using a virtual environment, make sure it's activated)
3. Configured Claude Desktop to use the correct Python executable path

Python version issues

If you have multiple Python versions installed, make sure you're using Python 3.10 or higher:

python3.10 -m venv venv  # Specify the exact version
