Overview

DeMCP is the a decentralized MCP network—a core infrastructure bridging AI and Web3. It offers providers (Agents) a platform to build, deploy, and monetize their own open-source MCP services while also enabling developers to access various large language models (LLMs) in a single place. DeMCP’s built-in crypto payment support (e.g., USDT, USDC) further opens the door to global participation. Through Secure Enclaves (TEE) and a blockchain-based registry, DeMCP aims to redefine the security and reliability of MCP, accelerating innovation for the Agent industry at scale.

In this study, we explore how the defillama-mcp server—a specific service in the DeMCP network—can be deployed within Phala Cloud’s Trusted Execution Environment (TEE). By combining defillama-mcp with Phala Cloud, it’s possible to ensure secure handling of credentials and reliable integration with on-chain data (e.g., DeFi metrics from DefiLlama) for AI-driven applications.

Why DeMCP on Phala Cloud?

1. Decentralized MCP Infrastructure: DeMCP’s open MCP services allow developers to quickly deploy or integrate with self-developed solutions. Having a TEE environment during deployment is especially beneficial when dealing with sensitive information or orchestrating commercial services with revenue sharing.

2. Security via TEE: Phala Cloud’s TEE isolates server processes from endpoint vulnerabilities, effectively encrypting data in-use. This means API keys, blockchain data, and user credentials remain protected—even if the surrounding environment is compromised.

3. Scalability and Trust: Combined with remote attestation and the open-source Dstack SDK from Phala, verifying the authenticity of the infrastructure becomes straightforward. This fosters end-user trust and encourages further adoption of MCP services.

Real-World Use Case: Deploying defillama-mcp

defillama-mcp is a service within the DeMCP network specifically tailored to interact with DefiLlama’s DeFi metrics. Below is how it work with Phala Cloud:

1. Setup and Registration: Signed up for Phala Cloud to establish the TEE environment and secure the necessary resources.

2. defillama-mcp Configuration: Cloned and configured defillama-mcp with the appropiate parameters and API credentials while sorting sensitive information with in the TEE -encrypted environment.

3. Deployment and Attestation: The defillama-mcp server was pushed to Phala Cloud and subjected to remote attestation to ensure it was indeed running within a genuine TEE.

4. Integration with AI Workflows: With defillama-mcp active, the service could feed real-time DeFi data into their AI tools—such as analytics dashboards or LLM-based agents—without exposing private credentials or risking data compromise.

Observed Advantages

• Seamless Payment Integration: DeMCP’s built-in crypto support simplified global usage, letting both providers and consumers transact in stablecoins.

• End-to-End Security: TEE-based encryption helped maintain privacy around crucial data, reducing the risk of malicious attacks or data leaks.

• Transparent Development: The DeMCP model allows Agents and developers to see what services are deployed, how they’re monetized, and whether they operate within attested TEEs.

• Rapid Deployment: Phala Cloud reduces setup complexity and speeds up release cycles (one-day launches), letting developers quickly iterate on new or updated MCP services.

Conclusion

By hosting key MCP services like defillama-mcp on Phala Cloud, DeMCP solidifies its mission to connect AI and Web3 securely. Developers can confidently deploy open-source MCP solutions in a verifiable TEE, benefit from decentralized payments, and keep sensitive data off-limits to unauthorized parties. As the Agent market matures, this synergy of decentralized infrastructure and hardware-level security stands to become a foundational piece for delivering dependable, scalable AI-Web3 applications.
