MCP Server SDK in Go and some servers I'm using myself

Catalog onlyCatalog onlySTDIO

Overview

MCP-Go SDK is a Go SDK designed for building Model Communication Protocol (MCP) tools and servers, facilitating the development of MCP-compliant applications that can interact with AI applications like Cursor IDE.

To use the MCP-Go SDK, you can start by checking out the example server provided in the servers/example directory. Implement your own tools by creating a struct that adheres to the mcp.Tool interface and register it with the server.

  • Provides a framework for building MCP-compliant tools. - Includes a flexible transport layer for communication. - Supports easy integration with AI applications. - Comes with example implementations for quick start.
  1. Building custom tools for AI applications.
  2. Creating servers that can process and respond to messages in real-time.
  3. Developing applications that require communication between different services using the MCP protocol.

Add to your AI client

Use these steps to connect MCP-Go SDK 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": {
    "mcp-go-sdk-dentaku7": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-go-sdk-dentaku7"
      ]
    }
  }
}

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": {
    "mcp-go-sdk-dentaku7": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-go-sdk-dentaku7"
      ]
    }
  }
}

Claude Code

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

.mcp.json (project root)

{
  "mcpServers": {
    "mcp-go-sdk-dentaku7": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-go-sdk-dentaku7"
      ]
    }
  }
}

VS Code (Copilot)

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

.vscode/mcp.json

{
  "servers": {
    "mcp-go-sdk-dentaku7": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-go-sdk-dentaku7"
      ]
    }
  }
}

Windsurf

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mcp-go-sdk-dentaku7": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-go-sdk-dentaku7"
      ]
    }
  }
}

Cline

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

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "mcp-go-sdk-dentaku7": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-go-sdk-dentaku7"
      ]
    }
  }
}
