🟠 [HIGH] Excessive filesystem access: / 
   Server 'filesystem' has --directory set to / — entire disk exposed. 
   Fix: Restrict to a specific subdirectory. 
 
🟠 [HIGH] Secret in env block of MCP config 
   Server 'github', env: GITHUB_PERSONAL_ACCESS_TOKEN 
   Contains a hardcoded secret value in the config file. 
   Fix: Move to .env file. 
 
🟠 [HIGH] Secret in env block of MCP config 
   Server 'slack', env: SLACK_BOT_TOKEN 
   Contains a hardcoded secret value in the config file. 
   Fix: Move to .env file. 
 
🟡 [MEDIUM] MCP server using HTTP without TLS 
   Server 'insecure-remote' connects via http:// — data not encrypted. 
   Fix: Use https:// instead.

## What it does 
 
Scans your MCP configuration files and finds: 
 
- 🔴 **Hardcoded API keys** — GitHub tokens, OpenAI keys, AWS credentials in plain text 
- 🟠 **Excessive filesystem access** — Servers with access to `/` or `/home` 
- 🟠 **Untrusted server sources** — MCP servers from pastebin, raw GitHub gists, etc 
- 🟠 **Known CVEs** — Checks against CVE-2025-49596, CVE-2025-6514, and more 
- 🟡 **Unpinned versions** — npx packages without version pins (supply chain risk) 
- 🟡 **Insecure transport** — HTTP without TLS for remote servers 
- 🔵 **Missing environment variables** — Referenced bu…
