在 OpenClaw 中安装
/install mcp-hello-world
功能描述
最小可行 MCP 服务器示例 - 在 OpenClaw 中调用 MCP 工具（add 计算 + hello_world 问候）
安全使用建议
This appears to be a straightforward example MCP server. Before installing: (1) review package.json and package-lock.json to confirm you trust the dependencies and their versions; run `npm audit` if possible; (2) note the small metadata inconsistency—SKILL.md contains an npm install hint while registry metadata said no install spec—confirm whether you will install from the bundled code or from an npm package name; (3) run the skill in an isolated/dev environment first (not production) and inspect network activity if you have concerns; (4) the skill does not request credentials, but if you later modify it to call external APIs, avoid embedding secrets in code or SKILL.md.
功能分析
Type: OpenClaw Skill
Name: mcp-hello-world
Version: 1.0.2
The bundle is a legitimate 'Hello World' demonstration for a Model Context Protocol (MCP) server designed for the OpenClaw ecosystem. It provides two simple tools (arithmetic addition and a greeting generator) implemented in Node.js using the official @modelcontextprotocol/sdk. The code in src/server.js and the supporting scripts (start.sh, src/full-test.js) are transparent, follow standard development practices, and align perfectly with the extensive documentation provided. No indicators of data exfiltration, malicious execution, or prompt injection were found.
能力评估
Purpose & Capability
Name/description match the implementation: a minimal MCP server using Node.js, providing two simple tools. Requested binary (node) and declared npm usage are appropriate and proportional to the stated purpose.
Instruction Scope
SKILL.md and bundled scripts direct the agent to install deps (npm install), start the server (npm start / node src/server.js), and call tools via mcporter stdio. The instructions reference example local paths and mcporter config but do not instruct reading unrelated system files or exfiltrating data.
Install Mechanism
No arbitrary URL downloads or extract steps; installation is via npm and the repository contains package.json/package-lock.json and source files. Note: SKILL.md includes an 'install' entry for npm, but the registry metadata earlier said 'No install spec'—a minor metadata inconsistency (see guidance). package-lock references a public npm registry mirror (npmmirror), which is typical of some dev environments but worth awareness.
Credentials
The skill does not declare or read any environment variables, credentials, or config paths beyond normal examples. There are no secrets requested and no excessive env/config access.
Persistence & Privilege
always:false and normal agent invocation are used. The skill does not request permanent platform presence or modify other skills or system-wide configuration in the files provided.
如何使用
- 确保已安装 OpenClaw（本地或 Docker 部署）
- 在对话框中输入安装命令：
/install mcp-hello-world - 安装完成后，直接呼叫该 Skill 的名称或使用
/mcp-hello-world触发 - 根据 Skill 的参数说明提供必要输入，即可获得结构化输出
