Overview

Mini-Blockchain is a simple blockchain implementation in Rust that demonstrates core blockchain concepts through block creation and chain validation, featuring a command-line interface (CLI) and MCP server integration.

To use Mini-Blockchain, clone the repository, navigate to the project folder, and run the application using Cargo. The CLI will provide options to add blocks, print the blockchain, and validate its integrity.

Basic blockchain implementation with SHA-256 hashing. - Menu-driven CLI for user interaction. - MCP server integration for external access to blockchain functionalities.

Learning and demonstrating blockchain principles.
Testing blockchain functionalities in a controlled environment.
Integrating with other applications via the MCP server.

Add to your AI client

Use these steps to connect Blockchain CLI in Rust in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "mini-blockchain-faustos88": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mini-blockchain-faustos88"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "mini-blockchain-faustos88": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mini-blockchain-faustos88"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "mini-blockchain-faustos88": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mini-blockchain-faustos88"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "mini-blockchain-faustos88": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mini-blockchain-faustos88"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mini-blockchain-faustos88": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mini-blockchain-faustos88"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "mini-blockchain-faustos88": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mini-blockchain-faustos88"
      ]
    }
  }
}
