The official Java SDK for Model Context Protocol servers and clients. Maintained in collaboration with Spring AI

Install java-sdk

Choose your AI client and copy the config.

Add to claude_desktop_config.json — macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\. Then restart Claude.

{
  "mcpServers": {
    "java-sdk": {
      "command": "npx",
      "args": [
        "@modelcontextprotocol/conformance",
        "server",
        "--url",
        "http://localhost:8080/mcp",
        "--suite",
        "active"
      ]
    }
  }
}

Add to Cursor

Or add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project).

{
  "mcpServers": {
    "java-sdk": {
      "command": "npx",
      "args": [
        "@modelcontextprotocol/conformance",
        "server",
        "--url",
        "http://localhost:8080/mcp",
        "--suite",
        "active"
      ]
    }
  }
}

Install in VS Code

Or add to .vscode/mcp.json in your workspace.

{
  "servers": {
    "java-sdk": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@modelcontextprotocol/conformance",
        "server",
        "--url",
        "http://localhost:8080/mcp",
        "--suite",
        "active"
      ]
    }
  }
}

Run in your terminal:

claude mcp add java-sdk -- npx @modelcontextprotocol/conformance server --url http://localhost:8080/mcp --suite active

Run the server directly:

npx @modelcontextprotocol/conformance server --url http://localhost:8080/mcp --suite active

Before you install: Install command taken from the project README. The README mentions API keys or tokens — you'll likely need to add them as environment variables ("env") in the config.
