Quick Start

npm install
npm run build
node dist/index.js

MCP Client Configuration

{
  "mcpServers": {
    "mc-changelog": {
      "command": "node",
      "args": ["${workspaceFolder}/dist/index.js"]
    }
  }
}

Path note: ${workspaceFolder} resolves to the project root in Trae/VS Code. On other editors use the absolute path: ["C:/path/to/mc-changelog-mcp/dist/index.js"]（把 C:/path/to/ 替换成你的实际路径）。

Configuration

本工具零配置即可用（内置默认值，任何环境开箱即用）。以下项目可通过环境变量或项目根目录 .env 文件覆盖（复制 .env.example 为 .env）：

变量	默认值	说明
`MODRINTH_API_BASE`	`https://api.modrinth.com/v2`	Modrinth API 根地址，支持自建网关/代理
`CHANGELOG_USER_AGENT`	`mc-changelog-mcp/1.0`	请求 User-Agent（Modrinth 要求标明来源）
`CHANGELOG_MODS_DIR`	`mods`	整合包内模组所在子目录名
`CHANGELOG_ENRICH_LIMIT`	`5`	增强信息（enrich）时每个模组返回的版本数量上限

优先级：环境变量 > .env 文件 > 内置默认值。改动后重启 MCP server 生效。

Testing

npm run build
npm run test:unit   # Unit tests (100% offline)
npm test            # Integration tests (requires network for Modrinth API)

Requirements

Node.js 18+
@modelcontextprotocol/sdk, zod
Network access required only for get_mod_version_info and generate_full_changelog
