MEFS-MCP-SERVER

MEMO MCP Server provides a standard storage interface for AI agents, allowing AI agents to save generated content to MEFS and providing data retrieval capabilities. It provides decentralized storage for AI agents.

Use Cases

• Encrypted data storage: Store AI-generated content to MEFS.

• User context retrieval: Store user behavior and preference data to MEFS, and quickly retrieve relevant user data in subsequent requests to provide to AI agents.

• Seamless data sharing: AI agents can achieve trustless data sharing through content identifiers (CID).

      },
      "shell": true,
      "cwd": "./",
    },
  },
}

Replace YOUR-PRIVATE-KEY with your EVM private key obtained from the EVM wallet.
