PopNx MCP 的三大支柱

这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。

它能帮你做什么

我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。

  • 连接方式: 在你的电脑上运行
  • 传输方式: stdio
  • 分类: 网络安全

安装

选择你使用的 AI 应用,然后复制设置。

安装之前

  • 基础检查:1 项中通过 1 项
  • 在你的电脑上运行,拥有你的用户账户的权限(文件、网络、应用)。
  • 注册中心没有列出需要填写的密钥。

你需要

  • npm已安装 Node.js(用于 npx 命令)

你用的是哪个应用?

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。

打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "yotta-verify": {
      "command": "npx",
      "args": [
        "-y",
        "@yottameta/yotta-verify-mcp"
      ]
    }
  }
}

在终端中运行这条命令

claude mcp add yotta-verify -- npx -y @yottameta/yotta-verify-mcp

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

{
  "mcpServers": {
    "yotta-verify": {
      "command": "npx",
      "args": [
        "-y",
        "@yottameta/yotta-verify-mcp"
      ]
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

在 VS Code 中打开

或者自己复制设置

粘贴到项目中的 .vscode/mcp.json

{
  "servers": {
    "yotta-verify": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@yottameta/yotta-verify-mcp"
      ]
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

yotta-verify-mcp · 元信MCP (YuanXin MCP)

YottaMeta's pre-install security scanner for Agent skills , exposed as a stdio MCP server. Before you install any skill, plugin or MCP server, it runs a deterministic static scan — prompt injection, malicious patterns, SKILL.md integrity and permissions — and returns a verdict , an audited badge , a CI gate and a report as MCP tools. Activates when configuring the 元信 MCP server in an MCP client, wiring a trust-scan into an agent / workflow, or calling the MCP tools. Zero dependencies (Python 3.8+ standard library); Windows + Linux + macOS; fully local and offline — no network calls, no execution of the scanned code.

What it is

The skill / plugin market has a trust problem: a 2025 survey of 22,511 skills found 140,963 issues, and 36% contain prompt injection. 元信 MCP gives you a deterministic answer before you install — the same scan as the yotta-verify CLI, exposed as four MCP tools so any MCP client (Claude, VS Code, Codex, Cursor, …) can call it.

It is a pre-install verifier , not a sandbox and not a runtime monitor: it only reads files and prints a report. It never executes the scanned code, never connects to the network for the scan, and never fixes anything.

Why use it

AdvantageDescription
Trust before installA deterministic verdict for any skill / MCP server, instead of "trust me"
Zero dependencyPython 3.8+ standard library; no daemon / database / network
Fully local offlineScans directories and npm tarballs on disk; nothing is executed or uploaded
Drop into any MCP clientStandard stdio MCP server — configure the server, and the four tools appear
Family synergySame rules table as yotta-verify (single source); verdicts merge with yotta-vetter / yotta-security-audit
Free & openMIT; the whole scanner is free

MCP tools

ToolWhat it does
scan_skillPre-install scan: target (dir / .tgz / npm package) → verdict + severity counts + findings
generate_badgeAudited badge: local SVG + shields.io URL; folds in validate / vetter / audit / version / tests
gate_checkCI gate: fail when the worst severity exceeds max_severity (default medium)
get_reportVerification report: Markdown or JSON, same format as the CLI

MCP client configuration

MCP configuration is optional. An AI agent may show you the target config file, the exact mcpServers JSON, and the effect, then wait for your explicit consent before writing anything. If you decline, use the bundled CLI scanner directly; the scan result is unchanged.

Tool reference

scan_skill

Scan a skill directory or package before install.

ParamTypeRequiredMeaning
targetstringyesSkill directory path, .tgz / .tar.gz path, or npm package name (auto npm pack to a temp dir, then scan)

Returns a JSON result: verdict, severity counts, and findings (prompt injection / malicious patterns / SKILL.md integrity).

generate_badge

Generate an audited badge (local SVG + shields.io URL).

ParamTypeMeaning
targetstringOptional: scan this to derive the verdict
verdictstringOptional: set the verdict directly
validatestringOptional: pass / fail (validate-skill result)
vetter / auditstringOptional: external verdicts to fold in
versionstringOptional: version label. Defaults to the scanner (yotta-verify) version (e.g. 0.1.1)
testsintegerOptional: engine test count
outstringOptional: write the SVG to this path

Note: the badge's version segment reflects the version of the bundled scanning engine

(yotta-verify), which may differ from the MCP package version. Pass version to override.

gate_check

CI pre-install gate.

ParamTypeMeaning
targetstringRequired: dir / package to scan
max_severitystringOptional: info / low / medium / high / critical (default medium)

Returns pass, verdict, worst, max_severity and an exit code.

get_report

Generate a verification report.

ParamTypeMeaning
targetstringRequired: dir / package to scan
formatstringOptional: json / markdown (default markdown)
outstringOptional: write the report to this path

Boundary

This is a local, offline, static scan:

  • Directory scan is fully offline — content never leaves your machine.
  • npm package scan only downloads the public package into a temporary directory (then removes it); it does not upload your content and does not execute the scanned package code.
  • It does not perform dynamic analysis, does not fix anything, and does not make the final decision. Treat the verdict as a strong signal and confirm any "install / don't install" decision yourself.
  • Only scan targets you are authorised to evaluate.

Installation of the skill

The package also ships a SKILL.md so an agent can explain how to configure and use the MCP server with explicit user consent. Pick any of the four methods below (skill files come from npm; GitHub can be slow without a proxy).

Method 1: npm one-liner (recommended)
# Optional China mirror: npm config set registry https://registry.npmmirror.com

npx -y @yottameta/yotta-verify-mcp --agent # install to the agent's default user-level skills dir npx -y @yottameta/yotta-verify-mcp --dir # point to the skills dir itself (e.g. ~/.codex/skills)

  • --agent installs to that agent's default user-level directory; --list shows each agent's default directory.
  • --dir installs to the given directory.
  • The installer also starts an MCP server when run with no arguments: npx -y @yottameta/yotta-verify-mcp.
Method 2: git clone (developers / git available)
git clone https://github.com/YottaMeta/yotta-verify-mcp.git <your-skills-dir>/yotta-verify-mcp
Method 3: GitHub Download ZIP (manual / no git)

On the GitHub repository YottaMeta/yotta-verify-mcp, click Code → Download ZIP, unzip it and put the yotta-verify-mcp folder into the agent's skills directory.

Method 4: install.sh (multi-agent one-liner script)
bash install.sh --agent <name>   # install to the agent's default user-level directory

bash install.sh --dir # install to the given directory bash install.sh --list # list agents -> default directories

Development & validation

Repository validation includes the MCP engine suite and a documentation consent regression:

# MCP engine suite (Python 3.8 / 3.13)

python scripts/test_yotta_verify_mcp.py

Documentation consent regression

node --test test/docs-consent.test.js

Run the MCP server directly for debugging

python scripts/yotta_verify_mcp.py
