Get the MCP Security Audit

One malicious MCP server can read your SSH keys, cloud credentials, and API keys — and the dangerous line is hidden inside a tool description you never read. This field guide is the exact audit to run on every server before it touches your machine: the 6-step hardening checklist (pin the version, read the tool descriptions, check the source, prefer OAuth over static env-var keys, isolate what you don't trust, keep tool approvals on), plus 3 copy-paste prompts that make your AI do the audit for you — one that reads your ~/.claude.json and risk-rates every installed server, one that scans a server's tool descriptions for poisoning, and one that vets a new server before you install it. Includes the delete-it-now red flags with real examples and the sourced threat landscape: CVE-2025-6514 (CVSS 9.6, mcp-remote RCE, JFrog/NVD), 43% command-injection (Equixly), 79% pass keys via env vars (Astrix, 5,200+ servers), the 12,230-tool 'Parasites in the Toolchain' study (IEEE S&P 2026), and tool poisoning (Invariant Labs, OWASP MCP03:2025). Every number tied to its real primary source.
