How do I use mc-rp-assistant-mcp?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mc-rp-assistant-mcp compare my resource pack with the vanilla one" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

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

Tool	Description
`read_packmeta`	Read pack.mcmeta from a resource pack directory or .zip file
`validate_rp_structure`	Validate a resource pack's structure and flag issues (missing files, format mismatches, large icons, etc.)
`list_rp_assets`	List all asset paths (textures/models/sounds/lang) in a pack. Supports both directories and .zip files
`compare_rpacks`	Compare two resource packs and report added, removed, and changed asset files
`search_rp_on_modrinth`	Search Modrinth for resource packs by name or tag. Returns up to `limit` results
`get_rp_info`	Get detailed info about a Modrinth resource pack by its slug or project ID
`validate_textures`	Validate textures for size limits (>2MB), naming conventions (lowercase, no spaces), and pack icon size
`analyze_lang_files`	Analyze language files (.lang) and detect missing translations across languages
`compare_rpacks_diff`	Compare two resource packs with detailed per-file info including file sizes for added/removed/changed assets

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_BASE`	`https://api.modrinth.com/v2`	Modrinth API 根地址，支持自建网关/代理
`RP_ASSISTANT_USER_AGENT`	`mc-rp-assistant-mcp/1.0`	请求 User-Agent（Modrinth 要求标明来源）
`RP_ASSISTANT_TEXTURE_MAX_MB`	`2`	单张纹理大小上限（MB），超过则标记为大纹理
`RP_ASSISTANT_PACK_ICON_MAX_KB`	`50`	资源包图标 `pack.png` 大小上限（KB）
`RP_ASSISTANT_DEFAULT_SEARCH_LIMIT`	`10`	Modrinth 资源包搜索默认返回条数
`RP_ASSISTANT_MAX_SEARCH_RESULTS`	`50`	Modrinth 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

Tool	Windows	macOS	Linux
`read_packmeta`	✅	✅	✅
`validate_rp_structure`	✅	✅	✅
`list_rp_assets`	✅	✅	✅
`compare_rpacks`	✅	✅	✅
`search_rp_on_modrinth`	✅	✅	✅
`get_rp_info`	✅	✅	✅
`validate_textures`	✅	✅	✅
`analyze_lang_files`	✅	✅	✅
`compare_rpacks_diff`	✅	✅	✅

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.

B3.4/5.0

Scored 2026-10-26 01:30 across 9 tools

Disambiguation3/5

Most tools target distinct operations, but compare_rpacks and compare_rpacks_diff overlap almost entirely (the latter mainly adds per-file sizes), and validate_rp_structure vs validate_textures both cover pack icon/texture size concerns. Descriptions hint at differences but do not clearly define when to choose each.

Naming Consistency4/5

Names overwhelmingly follow a snake_case verb_noun pattern, but domain abbreviations are inconsistent: rp, rpacks, packmeta, and lang appear without a single standard. Still readable and mostly predictable.

Tool Count5/5

Nine tools is well within the appropriate range for a resource-pack analysis assistant, with each major capability represented. There is no significant bloat or extreme thinness.

Completeness4/5

The set covers metadata reading, structure validation, asset listing, pack comparison, texture validation, language analysis, and Modrinth lookup. Minor gaps remain around model/sound validation or pack modification, but core analysis workflows are covered.
