Description
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）
Usage Guidance
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.
Capability Analysis
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.
Capability Assessment
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.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install mcp-hello-world - After installation, invoke the skill by name or use
/mcp-hello-world - Provide required inputs per the skill's parameter spec and get structured output
