What is the SubQuery MCP Integration?

The SubQuery SDK now supports MCP for supercharging development of SubQuery projects with AI tools. MCP is an open standard that connects AI models (like those in AI coding assistants) with the tools and files on your local machine—so the AI always understands the full context of your project.

With MCP, developers can now use AI-powered Integrated Development Environments (IDEs) like Cursor to create, build, and deploy blockchain indexers—without any authentication or private key access. Yes, this means your SubQuery indexer could be completely built with AI.

The best part? It all runs locally - just like the SubQuery CLI.

Why AI-Enhanced Indexers Matter in Blockchain Development

In today’s data-driven blockchain ecosystem, real-time access to indexed on-chain data is no longer a luxury; it's a necessity. Whether you're building DeFi protocols, NFT dashboards, or gaming dApps, reliable indexers are the backbone of fast, performant user experiences.

Now, with SubQuery’s MCP integration, developers can work faster and smarter with the help of AI:

  • AI agents can suggest and scaffold indexers in seconds
  • AI IDEs with MCP integration reduce human error and accelerate time-to-deployment

All this on top of our recent query service AI upgrade which allows developers to query indexed blockchain data in plain English. This marks a paradigm shift in blockchain development, moving from manual setups to intelligent automation.  

Key Features of SubQuery MCP

SubQuery MCP supports all major SubQuery CLI functionalities, now enhanced with AI capabilities. Already you can benefit from the below:

  • Create new SubQuery indexer projects
  • Build and debug SubQuery projects with AI-assisted coding
  • Publish projects to IPFS directly from your local machine
  • Import smart contract ABIs to auto-generate data sources
  • Deploy to a managed hosting partner (like OnFinality) in just a few clicks 

And we're just getting started — more features are on the way to make SubQuery's MCP integration even more powerful. Soon, you’ll be able to deploy your indexers to the SubQuery Network directly from the CLI, making it easier than ever to tap into the network’s decentralised and cost-effective infrastructure — no need to visit the app.

How SubQuery MCP Advances the Role of Indexers

By bridging AI and blockchain infrastructure, SubQuery MCP redefines what indexers can do. This isn't just about automation—it’s about intelligent collaboration between humans and machines.

Here’s how:

  • For Developers: Instant project scaffolding and deployment saves hours of manual setup.
  • For AI Agents: Enables agent-driven workflows for querying and modifying indexed data.
  • For the Ecosystem: Lowers the barrier to entry for builders in Web3 and speeds up product development.

According to Gartner, by 2026, more than 80% of software development will incorporate some form of AI pair programming or agent interaction. SubQuery is ahead of the curve.
