Connecting AI Agents Across Chains: MCP + t3rn Integration

Gino Winnefeld

Apr 24, 2025

Hey there! I've been thinking a lot about how we can make AI agents work seamlessly across different blockchains, and I'm really excited about the potential of bringing together the Model Context Protocol (MCP) and t3rn protocol.


The Big Idea

The blockchain space is incredibly fragmented right now. We've got all these amazing networks, but they don't talk to each other very well. Meanwhile, AI agents are becoming increasingly important but face huge challenges when trying to operate across multiple chains.

By combining MCP (which gives AI models a standardized way to interact with external tools) and t3rn (which handles crosschain operations), we can build something really powerful: AI agents that can work across the entire blockchain ecosystem.

Why This Makes Sense

MCP is essentially becoming the "USB-C port for AI" or like HTTP was for the internet, a universal communication standard. It lets any AI model talk to any tool using the same language. This is huge for simplifying how AI agents interact with blockchain protocols.

Meanwhile, t3rn solves the crosschain problem:

  • A Settlement Layer for finalizing transactions across chains.

  • An Economic Layer that incentivizes network participants.

  • An Interoperability Layer connecting different blockchains.

Together, they create the perfect foundation for crosschain AI agents.

How It Would Work

We could build specialized MCP Servers that expose t3rn's functionality as tools that any AI agent can use. An agent could:

  1. Request a crosschain action through the MCP Server.

  2. The server interacts with t3rn protocol.

  3. Results get passed back to the agent.

This approach abstracts away all the complexity of different blockchain APIs. The AI just needs to know the MCP interface, and it can leverage all of t3rn's crosschain capabilities.

The Killer Use Cases

This opens up some really exciting possibilities:

In DeFi:

  • AI agents managing portfolios across multiple chains, automatically moving assets where they'll generate the highest yield

  • Crosschain arbitrage bots that can spot price differences between DEXs on different networks

  • Lending/borrowing services that can pull liquidity from anywhere

For Data & Analytics:

  • Agents that collect and analyze data from multiple blockchains, giving you insights you couldn't get from looking at chains in isolation.

  • Secure crosschain data transfer with privacy controls built in.

For Automation:

  • Multichain workflows managed by AI, imagine supply chain tracking that spans several specialized blockchains.

  • AI powered DAOs that can execute governance decisions across multiple networks.

  • Smart contracts that leverage AI to adjust behavior based on crosschain events.

Challenges We Need to Solve

Let's be real, this isn't going to be simple:

  • Security is paramount when you're dealing with crosschain operations.

  • We need to balance AI autonomy with appropriate user controls.

  • Regulations around both AI and blockchain are evolving rapidly.

  • Scalability will be crucial as more agents start using the system.

But the upside is huge, we're talking about building infrastructure that could fundamentally change how blockchain applications work by making crosschain operations accessible to AI agents.

Next Steps

I think the path forward involves:

  1. Building prototype MCP Servers for t3rn.

  2. Creating frameworks that help developers build AI agents that leverage this integration.

  3. Testing with some focused use cases in DeFi or data analytics.

  4. Iterating based on real world feedback.

This could be the foundation for a whole new generation of crosschain applications powered by AI. I'm excited to see some of these new applications come to life. 

We are excited to roll out t3rn 2.0, a ground-up redesign of t3rn’s cross-chain execution and bridging stack that replaces trust-based coordination with a cryptographically verifiable, trustless execution model. Powered by the new LiquidityWellCompact architecture, which unifies order management, escrow, and liquidity into a single gas-optimized contract, t3rn 2.0 makes cross-chain transactions significantly cheaper, faster, and more reliable. With automated retries, stronger liquidity incentives, and backward-compatible, composable APIs, t3rn 2.0 moves cross-chain execution closer to being a simple, predictable infrastructure primitive rather than a fragile special case.

We’re happy to announce Lucky Bunny, our NFT PFP drop celebrating community, interoperability, and a bit of luck in the t3rn ecosystem. Inspired by the Lucky Cat and t3rn’s bunny mascot, Lucky Bunnies symbolize curiosity, movement, and connection across chains. Minted on Rari Chain, this drop is a thank-you to the t3rn community, offering simple perks like future allowlists, raffles, and early access. With an accessible mint and proceeds supporting TRN buybacks, Lucky Bunny is about being part of the story — where culture and infrastructure grow together.

As multichain activity becomes a core part of Web3, simple asset transfers via bridges are no longer enough to support increasingly complex cross-chain workflows. While bridges effectively move assets between chains, they stop short of coordinating multi-step actions, leaving users exposed to partial executions, higher costs, and manual failure handling. t3rn addresses this gap by with cross-chain execution: an outcome-driven, atomic approach where all actions across multiple chains either complete together or fully revert. Rather than managing individual transactions, users define the desired result, and the protocol guarantees execution without leaving funds in unintended states. By operating above bridges and messaging protocols, t3rn provides execution-level interoperability, enabling safer, more reliable multichain applications as blockchain ecosystems continue to fragment and scale.
