Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package mc-rp-assistant-mcp
Claude Code 
claude mcp add mc-rp-assistant -- npx -y mc-rp-assistant-mcp@1.0.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "mc-rp-assistant": {
            "command": "npx",
            "args": [
                "-y",
                "mc-rp-assistant-mcp@1.0.0"

mc-rp-assistant-mcp

MCP server for Minecraft resource pack analysis, validation, and management. Reads pack.mcmeta, validates structure, lists assets, compares packs, and queries Modrinth.

Tools

ToolDescription
read_packmetaRead pack.mcmeta from a resource pack directory or .zip file
validate_rp_structureValidate a resource pack's structure and flag issues (missing files, format mismatches, large icons, etc.)
list_rp_assetsList all asset paths (textures/models/sounds/lang) in a pack. Supports both directories and .zip files
compare_rpacksCompare two resource packs and report added, removed, and changed asset files
search_rp_on_modrinthSearch Modrinth for resource packs by name or tag. Returns up to limit results
get_rp_infoGet detailed info about a Modrinth resource pack by its slug or project ID
validate_texturesValidate textures for size limits (>2MB), naming conventions (lowercase, no spaces), and pack icon size
analyze_lang_filesAnalyze language files (.lang) and detect missing translations across languages
compare_rpacks_diffCompare two resource packs with detailed per-file info including file sizes for added/removed/changed assets

Exported Functions

  • readPackMetaExport(packPath) — Read pack.mcmeta
  • validateRpStructureExport(packPath, mcVersion?) — Validate pack structure
  • listRpAssetsExport(packPath, limit?) — List asset files
  • compareRpacksExport(oldPackPath, newPackPath) — Compare two packs
  • searchRpOnModrinthExport(query, limit?) — Search Modrinth
  • getRpInfoExport(slugOrId) — Get pack info from Modrinth
  • validateTexturesExport(packPath) — Validate textures
  • analyzeLangFilesExport(packPath) — Analyze language files
  • compareRpacksDiffExport(oldPackPath, newPackPath) — Detailed pack comparison

MCP Client Configuration

Add to your MCP client config (e.g., Trae settings.json or MCP CLI config):

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

Path note: ${workspaceFolder} resolves to the project root in Trae/VS Code. If using another editor, replace with the absolute path, e.g. ["C:/Users/xxx/Desktop/mc-rp-assistant-mcp/dist/index.js"].

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
RP_ASSISTANT_MODRINTH_API_BASEhttps://api.modrinth.com/v2Modrinth API 根地址，支持自建网关/代理
RP_ASSISTANT_USER_AGENTmc-rp-assistant-mcp/1.0请求 User-Agent（Modrinth 要求标明来源）
RP_ASSISTANT_TEXTURE_MAX_MB2单张纹理大小上限（MB），超过则标记为大纹理
RP_ASSISTANT_PACK_ICON_MAX_KB50资源包图标 pack.png 大小上限（KB）
RP_ASSISTANT_DEFAULT_SEARCH_LIMIT10Modrinth 资源包搜索默认返回条数
RP_ASSISTANT_MAX_SEARCH_RESULTS50Modrinth 搜索返回条数硬上限

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

扩展默认配置：编辑 src/rp-config.json（构建后为 dist/rp-config.json）可调整搜索上限、pack.png 大小阈值与 MC 版本 → pack_format 映射，无需改代码。

Requirements

  • Node.js 18+
  • @modelcontextprotocol/sdk, zod, adm-zip
  • adm-zip is required for .zip / .mcpkg resource pack support — included as a dependency

Development

npm run build   # Compile TypeScript
npm run test:unit  # Run unit tests
npm test        # Run all tests

Testing

npm run build
npm test

All unit tests are offline except searchRpOnModrinth and getRpInfo which gracefully return empty results when no network is available.

Platform Compatibility

All tools use cross-platform Node.js fs and path APIs. .zip support requires adm-zip. Network-dependent tools (search_rp_on_modrinth, get_rp_info) work on all platforms when online; they return empty results gracefully when offline.

  • Node.js 18+
