DuneLink

A modern bridge connecting Dune Analytics data to intelligent agents through Model Control Protocol (MCP).

Overview

DuneLink enables seamless integration of blockchain data analytics into your AI applications. By leveraging Dune Analytics' powerful query capabilities with the Model Control Protocol, this service allows LLMs and other AI systems to access on-chain data through simple, natural language interactions.

Core Capabilities

Data Retrieval Tools

Tool	Description	Use Case
`get_latest_result`	Retrieves pre-computed query results	Quick access to existing data
`run_query`	Executes a query on-demand	Real-time data analysis

Data Format

All data is returned in CSV format, providing:

Universal compatibility
Easy parsing by most data analysis tools
Human-readable output

Getting Started

System Requirements

Python 3.10 or higher
Valid Dune Analytics API key (Get yours here)

Quick Setup

Clone & Navigate

git clone https://github.com/olaxbt/dune-query-mcp.git
cd dunelink

Environment Setup

# Create virtual environment
python -m venv .venv

# Activate it
source .venv/bin/activate  # Linux/Mac
# or
.venv\Scripts\activate     # Windows

# Install dependencies
pip install -r requirements.txt

Configure API Access

# Copy example config
cp .env.example .env

# Edit with your API key
echo "DUNE_API_KEY=your_key_here" > .env

Usage

Running the Service

DuneLink offers two ways to run:

As MCP Service

python run.py

This starts the MCP service on default port 8000.

As Web Server

python flask_app.py

This provides access to the web interface and REST API endpoints.

Integrating with Applications

MCP Client Integration

from mcp.client import Client

# Connect to DuneLink
client = Client("http://localhost:8000")

# Get latest results for a query
csv_data = client.call("get_latest_result", query_id=1234567)

# Execute a query
query_results = client.call("run_query", query_id=1234567)

REST API

Endpoint	Method	Description
`/dune/health`	GET	Service health check
`/dune/query/{query_id}/latest`	GET	Retrieve latest results
`/dune/query/{query_id}/execute`	POST	Run a query

Example REST Call:

curl -X GET http://localhost:5000/dune/query/1234567/latest

Advanced Configuration

Environment Variables

Variable	Purpose	Default
DUNE_API_KEY	Authentication for Dune API	None (Required)
PORT	Server port	8000

Performance Tuning

For high-volume query execution:

# Set a higher timeout for long-running queries
export DUNE_QUERY_TIMEOUT=600  # 10 minutes in seconds

Troubleshooting

Common issues and solutions:

Problem	Solution
API Key errors	Ensure `.env` file exists with valid key
Timeout errors	Increase timeout for complex queries
CSV parsing issues	Check query returns proper tabular data
